Tokina AT-X SP 60-120mm F2.8 manual focus Super-Portrait lens

2022-08-16 Thread JC OConnell
Just got ahold of my second copy of subject lens
(yes, its so good, I wanted a spare). They are
hard to find in a PENTAX PK mount. Recently one showed
up on ebay BIN for 200 pounds in LN condition
so I grabbed it. When I bought my first one twenty years
ago, I found the zoom range ideal for people shots
of all types on film. Seems even better with the digital
K-1

heres a simple sample nature photo showing the incredible resolution
for a zoom https://www.jchriso.com/temp/tree.jpg ( resized for web )
this is the same photo but shows a 100% mag crop
of the center of the image https://www.jchriso.com/temp/treecrop.jpg

Re: Shade for Tokina ATX PRo 28-70/2.6-2.8? - And some interesting history

2020-07-09 Thread John
This was always my favorite walking around lens. Mine failed a few years ago 
when the 'A' contact ring wore out.


It's the lens I dropped & Tokina fixed under warranty even though I told them 
I'd dropped it & that anyway it was out of warranty because I bought it used.


I got maybe 10 good years use out of it after they repaired it.

Igor's question prompted me to check KEH & eBay and I found one in Pentax Kaf 
mount in Japan on eBay with a "Buy it Now" price just about same as I remember 
paying KEH for the first one back in 2003.


It arrived at my front door just a few minutes ago.

I'm so happy. I will try to be a little more careful with this one.  8^)

Interesting. He mentions the Vivitar Series 1, 90/2.5 and says it’s heavier. It 
is indeed because it’s all metal and built like a tank. He also fails to 
mention that the Vivitar came with an optical converter that makes it 1:1. I 
was heartbroken because I thought workers had stolen my pristine copy, but I’m 
happy to report that I found hiding at the rear of a shelf just the other day.

Re: pentax/tokina 24-70/2.8

2016-02-24 Thread P.J. Alling
The more light you have hitting the metering sensor the more accurately 
it is measured.  That's pretty much true with any meter.  Pentax makes a 
number of over optimistic assumptions I think, but the calculations 
preformed from a wide open reading of the existing light, seem to be 
much better than the readings I get stopping down.


I've tested it with the FA 43mm limited.  Using the lens in dim light, 
set at f4-5.6 (on A), I get pretty good exposures.  Stop down metering 
in the same situation with the same aperture yields wildly varying 
shutter speeds, usually running to under exposure due to much shorter 
shutter speeds*, but sometimes to much longer shutter speeds.


The reason I tested it at all was that I noticed that the M 85mm in dim 
light was often giving extremely under exposed images, (sometimes 
extremely over exposed, but not as often).  The diaphragm doesn't seem 
to be sticky, it doesn't seem to have problems in bright light.  However 
when using the 43mm limited and A 24 f2.8 I had fewer metering problems.


*I've been experiencing this since the *ist-D days.  The K20D was a 
little better, the K-5II a little better than that, but open aperture 
metering still gives better, more consistent exposures in dim light.

OK, this really confuses me, because when you meter wide open, you are 
assuming perfect linearity from wide open to the projected aperture, 
and I seem to recall reading an article that explains wu this 
assumption tends to be overly optimistic, without even considering the 
difference between t-stops and f-stops. I believe that the problem is 
also exacerbated on digital sensors which are also particularly 
sensitive  to the direction at which light hits the sensor (though 
less so now).  I've got a few brain cells that are tickled thinking 
that this might be related to why split prism (and microprism) 
viewfinders look so much darker at smaller apertures than at larger ones.


Also, while things seem to have improved in the past few years, I have 
found Pentax metering so unpredictably inaccurate that if I don't want 
my highlights blown out, in the vast majority of cases I use the green 
button (or other exposure estimation), a test exposure and the 
histogram (or at least bracketing) for the vast majority of my shots 
anyways, so my workflow with K and M lenses, even without an aperture 
simulator, to usually be identical to using A and AF lenses.


Since every moving part increases complexity, cost, and opportunities 
for the camera to break, the ability to use unreliable auto exposure 
on a few $40 used lenses falls somewhere between un-needed and 
undesirable to me.


Features that I would like to see, which would cost Ricoh nothing but 
a little bit of programming (which I'd probably do for them for free 
given the source code):


Having the RAW/Fx button not only put the camera into on occasionally 
used mode, but take it out of that mode with a simple press. As it is, 
if I press the button accidentally, it will change the mode of my 
camera, and then I have to go through the menus to undo what I 
accidentally did.


Having the histogram read raw files, rather than the jpegs so I can 
tell what my sensor is really doing.


Having astrotracer read the lens focal length from the manual settings 
so I can use it with manual focus lenses (or telescopes).


Restore the ability to set astrotracer to times less than 10 seconds. 
Often, when shooting the full moon, I'll want astrotracer to stop the 
blur, but only want a 1 second exposure.  Honestly, I'd rather it went 
down further than that.


While we're at it having a lunar astrotracer mode, because the moon 
moves differently than the stars relative to the ground.


Having astrotracer work like every other exposure mode so that I don't 
have to go through all of the menu rigamarole everytime I want to 
review a frame or change the shutter time.


Have bracketing work on astrotracer.

Have astrotracer/non-astrotracer bracketing so that when you are 
shooting night landscapes you can get clear shots of both the 
foreground and the stars to recomposite later.


(come on guys, astrotracer is cool, you advertise it, polish it up so 
that it's not just a kludgey parlor trick).


Being able to set exposure times longer than 30 seconds, with the mode 
of being able to easily take dark field frames at the times of my own 
choosing without having to fiddle with a lens cap.


Have a metering mode that takes a sample picture (or several) and get 
set the exposure (or exposure and bracketing) to capture all of the 
data, rather than taking a guess and having to guess based upon the 
inaccurate jpeg based histogram. While we're at it, have the info

When shooting for HDR, being able to bracket more than two stops between

doesn't really gain me a lot in the cases where I need the added 
latitude, and I don't want to have to shoot five exposures to get the 
latitude I want.


Being able to choose bracketing independently of what the auto exposure 
value is.


Being able to bracket the focus (when shooting macros with an autofocus 
lens).


Recording the shutter press time stamps more accurately than the nearest 
round second, and by when the shutter is activated rather than when the 
file is written.  I'm not sure which of these cause bracketed photos to 
show up in lightroom in some bizarre, semi random order.


Wifi based flash control (now theoretically possible with the K-1).



The only one that makes sense is Pentax thought that they could get away
with orphaning all those K mount lenses prior to the A series and add a
few bucks per unit to the bottom line. The Shit Storm that hit them was
a huge surprise, (which shows how tone deaf a company can be), so they
got some software engineers to institute the green button kludge.

It's worth noting that we are likely to see even the remaining
mechanical diaphragm actuation lever eliminated in the future and all
interaction between the camera body taking place through electronic
communication. Nikon is already moving in that direction and making
lenses with built-in electronically-controlled diaphragms (Canon has
had only electronic diaphragm control since the introduction of the EF
mount in 1987). Though it's early days, such lenses are not compatible
with any Nikon DSLR prior to the D3. Tamron's two new lenses are
electronic-only for diaphragm control and incompatible with early
Nikon DSLRs. This is likely why Tamron and others offer so few lenses
in Pentax mount – it's much easier to deal with multiple lens mounts
when there's as little mechanical interaction between camera body and
lens as possible.

When Pentax does introduce electronic aperture control in the future I
expect them to go the Nikon route and make most lenses and bodies
backward and forward compatible.

Only a tiny minority of Pentax shooters care about the mechanical
aperture-position sensor (and I suspect they're all old curmudgeons on
the PDML!) which, after all, is only needed for lenses made between
1975 and 1982 – a small fraction of the K-mount's 40+ year history.
According to Don Nelson it added too much to the cost of camera
manufacture, both in parts and assembly (and now it would also
necessitate re-writing lots of computer code because none of Pentax's
DSLRs have provision for reading/using data from the potentiometer).

Re: pentax/tokina 24-70/2.8

2016-02-24 Thread P.J. Alling

Bottom line is the only reason that makes any real sense.

The rational has variously been that it was inaccurate, but it isn't as 
inaccurate as stop down metering can be.


Space in the camera has been touted as an issue, but the K-1, (and for 
that matter the K10/20D), cameras aren't that small, so there's probably 
space it would probably have required slightly different packaging.


The only one that makes sense is Pentax thought that they could get away 
with orphaning all those K mount lenses prior to the A series and add a 
few bucks per unit to the bottom line.  The Shit Storm that hit them was 
a huge surprise, (which shows how tone deaf a company can be), so they 
got some software engineers to institute the green button kludge.


I doubt that leaving the aperture simulator off the original *ist Film 
camera and *ist-D saved them much more than ¥5000 in manufacturing 
costs, but over the production run of several hundred thousand cameras 
that kind of savings is nothing to sneeze at.

Pentax Fora seems to think that the new lens is made by Tamron, but AFAIK 
Pentax never had a relationship with them, while a number of Pentax and Tokina 
lenses were in recent history co developed, including the 10-17mm fisyeye zoom 
and the 12-24mm.

__

As someone else noted, Pentax has gotten super zooms and the old FA 2X TC from 
Tamron. I suspect the current DA 18-135 is a Tamron design, also possibly the 
DA 16-85 (which is now my go-to lens).

As for the Pentax/Tokina lenses, Tokina developed the 12-24. All the other 
joint Pentax/Tokina lenses were designed by Pentax.

As for the rebadged Tamron lenses, I suspect that Pentax put off a decision on 
the full-framer until the last minute. Then there wasn't time to develop lenses 
for it in-house. Hence they went to Tamron. And Jun Hirakawa now works for 
Tamron, and he may have been involved in designing them. These rebadges are 
reviewed to be quite good.

Both the D-FA 24-70/2.8 and the D-FA 15-30/2.8 lenses appear to be rebadged 
Tamrons.
However, the most famous lens designer working for Pentax during the 
FA*-series era (Mr. Jun Hirakawa, designer of the FA* 1.4/85mm) now works 
for Tamron, hence there must be some Pentax heritage in above new "Pentax" 
lenses.

Paul, its a Tamron lens, and is supposed to be pretty good. Pentax puts their 
own coating on it.

The forthcoming 15-30 and 70-200 are also Tamron lenses. They are also supposed 
to be good.

But in some ways Pentax never learns. They are still putting the SDM label on 
new lenses.

So what are Pentax's lens designers doing?

No need to expect, it's already arrived and in stock at B&H, (as well as 
other fine retailers).

Weather sealed with HD coatings.

It was my workhorse lens for almost 10 years.

the 28-80/2.8 if I ran across it.

I now have the comparable Sigma 24-70/2.8.

The only thing I don't like about it is the 28-70/2.8 was internal
focus/internal zoom&  didn't change length. Looking at the Tokina

If anyone is interested in a well-buildt inexpensive manual focus push

than $50.00 new in the box. Mine arrived in two days. Brief hand-held 
testing looks sharp with nice contrast. These were designed for FF. Five

Re: Anyone tried the Tokina AT-X AF 28-70 F2.8 Lens?

2015-02-16 Thread Igor PDML-StR


Darren,

Thanks for the followup. I had never heard about "Angenieux", either in 
the context of this lens or in any other context.

So, it was interesting to read this (fairly recent) writeup.

Also, based on the description, I think my lens is actually "II",
as it has a bayonet hood.

The non-PRO version had rotating front element, and IIRC, 72mm filter.
The rest had 77mm filter.

SV was lighter and reportedly not as good as the preceeding versions.

The f/2.8 Tokina AT-X PRO 28-70mm is the first auto-focus lens I bought
to go along with the PZ-1p that was my first auto-focus SLR.

Within a year of getting the PZ-1p, Pentax came out with the *ist-D. On
APS-C cameras the field of view makes it the equivalent of a 42-105mm
zoom. That's the only real "con" I can think of for that lens; on APS-C
you lose the wide end of the zoom range. I don't think that's going to
be a problem for Pentax's putative Full-Frame DSLR.

Just before I deployed to Iraq in 2004, I dropped the lens damaging the
zoom gear & I had to send it to Tokina for repair. They returned it to
me in Iraq, repaired under warranty & it's been my most frequently used
lens for the last decade.

Since I got a K-3 I've been having a problem where I mount the lens &
the camera displays an error "--" indicating it can't read the aperture.
I sent it to Erik Hendrickson in Knoxville. He didn't find anything
wrong with it so he just cleaned the contacts & checked the AF gears.

Since I got it back, I noticed that the lens only gives the "--" error
when I zoom to 28mm. From about 30mm on up, it works fine. I think the
problem is related to wear in the zoom ring & in the detent that locks
the aperture selector into the 'A' position. I've been thinking about
sending it to Tokina to see if they can/will fix the problem.

It's a great lens. I don't think I've ever seen one offered for sale
since I bought mine.

As an alternative to sending it to Tokina, I've been thinking about
putting in a "wish list" request with KEH to see if I can get another one.

Kennyboy has a review of that lens on his website, It might be one of 
his good reviews, (he does have good ones occasionally) or it may be one 
of his trademark hands off reviews, I' can't be bothered to read it, but 
it might actually have useful information.

Years ago I owned the Tokina 28-70 AT-X Pro II 2.6/2.8 in K mount and I
remember being very impressed by it. It is heavy and made of neutron
star innards! I recall it being sharp when stopped down a couple, but
reasonable wide open. It was certainly amongst my kit up until the time
I bought an EOS D60 in 2003 and sold the bulk of my K mount kit for some
lenses to go with a DSLR. I may have even obtained an EF version of the
Tokina - but memory does not serve well here.

Re: FSF: Some Pentax A, FA, Tamron, Tokina, Vivitar, etc lenses and 1.7x AF Adapter

2013-11-29 Thread Miserere
Embarrassingly, I briefly lost my FA 20mm f/2.8 this afternoon. Now
that I've found it again, I'm downgrading its external condition to an
8 due to some scuffs on the barrel; nothing that affects its physical
integrity. Front cap is original Pentax, rear cap generic. I also have
(and always have had) a 67mm filter on it.

Needless to say, all lenses are free of fungus and have oil-free
snappy blades. If you're not happy with your purchase, you have 10
days to return it to me for a refund (minus shipping costs).

Cheers,

Looks like it's an 'A' lens that's not locked in the 'A' position.

The red dot is there on the side of the bayonet. If you follow the
vertical side of the letter 'P', you can just barely see it (or its
reflection) right under the edge of the flange.

Re: Question about Tokina Zoom 28-210 vis a vis Pentax

2013-07-19 Thread Jeffery Smith
My 28-80 2.8 Tokina zoom is built like a tank and is better with film than with 
digital. The zooms that really seem to have gone up in quality (optical and 
build) are the Sigmas and Tamrons, IMO. Since the Tokina is a gift, that trumps 
paying for a Pentax, Tamron, or Sigma. :-)

Re: Perspectives on Tokina AT-X 400/5.6 & Pentax M* 300/4

2012-09-21 Thread Mark C
I have both the Tokina ATX and the A* 300mm f4 (not the M* but I think 
the lenses are the same optical formula.)


Hands down, I would take the Tokina over the A*. I have toted my A* 
around for over a decade and have barely used it. It is certainly an 
above average lens, but not on par with some of the truly excellent star 
series lenses.


I have found the Tokina to be pretty good, especially at f8. It does get 
soft at f 5.6. I searched high and low for the Tokina about a year after 
it was discontinued, IIRC in the late 90's, and ultimately bought a 
Sigma 400mm f5.6. I later swapped that lens for the Tokina and a bit of 
cash. I think I paid about $650 for the Tokina then. My original sample 
got the fungus. I looked for a replacement for several months and got a 
SIgma 135 - 400 when I could not find one. Later I bought a replacement 
Tokina off ebay last year (or maybe the year before) for about $400. The 
SIgma zoom is a nice lens at 400, but not on par with the Tokina.


The SIgma 400 f5.6 macro was probably a better lens than the Tokina 
400mm. I recall someone here on the list noting that the Sigma was 
sharper than the Tokian at 5.6, but the Tokina surpassed the Sigma at 
f8. Not sure if that is true but at the time I did not understand how 
important it is for a telephoto to be very sharp wide open.


I have several shots with the Tokina on my website -

http://www.markcassino.com/b2evolution/index.php/spotted-sandpiper

http://www.markcassino.com/b2evolution/index.php/white_throated_sparrow

http://www.markcassino.com/b2evolution/index.php/of-finches-and-thistle

The goldfinch shots were taken with the fungus-clouded lens.

Overall, I've found the Tokina to be a great lens. The biggest drawback 
is that it lulls you into shooting without a Tripod (too small and 
light) and images suffer from that. Even with AS, you need a tripod for 
telephoto work. Ahd like I said - I almost never use the A* 300mm f4. 
Just too short, focuses too far away, and not so hot optically. I had 
hopes that using it with the Q would finally be a nice for the 300mm, 
but my recent tests have not born that out.

The 300mm f4 M series lens is rather rare.
The 300mm f4 A lens is identical and more available..
I often take the 300/4 A with the AF1.7X on trips.
It makes a sharp and small birding combo.

I think that I tend to look at little Pentax lenses, which they are
good at.  Really, though, I've seen some good images from that DA40
XS.  Paper thin and cheap, too?  I hope they make a smaller camera to
put it on.  Really, Sony NEXs are tiny bodies with lenses like logs,
and Pentax makes a brick with a lens like a slice of salami.

Subject: Taking the Tokina out for some exercise

I had been having some mixed feelings about my Tokina 80-200/2.8.  It seemed 
like I just couldn't get sharp photos with it.  Last night, some friends were 
playing at the Trout Farm up in Zayante, and I decided to get a little more 
practice with it.  Since I did manage to get a few shots, that actually were 
sharp, even wide open, I realized that the lack of sharpness isn't entirely the 
lenses fault.  Big surprise, that I'm the limiting factor in the sharpness of 
my photos.  

After reading the article on sharpness in TOP, I think that a lot of my 
perception of lack of sharpness is actually lack of contrast.  I think that 
other things also come into play, such as the difficulty of manually focusing 
on moving subjects in low light.  Even with a split prism focusing screen.  For 
that matter, even with live view it is difficult when the subjects move faster 
than the latency of the image.  If I actually had money to buy glass, I'd be 
very tempted to look for the autofocus version of this lens, not only would it 
make focusing easier in many cases, but the shake reduction would work a lot 
better too.

While f/2.8 is as fast as a zoom lens gets, I certainly notice it being a lot 
slower than my primes.  There were several times last night, on TAv mode where 
the ISO went all the way up to 25,600.

Things also might have been a bit sharper if I hadn't left my ball head at home 
and could have used my monopod. 

The other thing that I've been playing with is my post processing trick of 
dialing up clarity all of the way, up to the point that it nearly looks like 
over done HDR, but with a lot more noise. Interestingly, I think that when I 
use this trick the photos work best when they are actually just a bit soft to 
start with.  I'm guessing that this is because the clarity slider does 
something not entirely unlike sharpening, so if I under sharpen first, then 
they don't look quite so oversharpened afterwards.

For them that care, I put the 24 best up on flickr, here they are with the 
fluidr front end so you can see the exposure data:
http://www.fluidr.com/photos/ellarsee/sets/72157631375658366/

Interestingly, 20120901-LRC70488.jpg was something like five stops 
underexposed.  I'm not sure how.  I normally shot the drummer at something like 
1/40 f/2.8 ISO 1, and it was shot at 1/125 f/5 ISO 125.  It's a bit rough, 
but still a testament to capabilities of the K-5 that I was able to get it that 
good.

There are two problems with that:

1)  The FA* 80-200 probably weighs twice what the Tokina does.

2) At the end of the week, I'd be asking you how much you'd want for the FA*, 
and I can't afford to adopt another one of your old lenses right now.

And yes, the framing is rather strange.  It was one of those mistakes that

Thank you Steven.  I think the skill is in the taking the photos, the art is in 
throwing most of them away.  The trick that I'm playing with the clarity slider 
sort of reminds me of when we discovered solarizing prints as kids.  Someone 
accidentally exposed a print that was still developing to light, and the 
results were pretty cool.  I had that one shot last month that was really nice, 
except for being totally out of focus, and screwing around with it I noticed 
how pushing the clarity past the reasonable point led to some nice results.

One of these days, I need to spend a little more time photographing in decent 
light.  Unfortunately, then I won't have an excuse for crappy image quality.

I think that it is front focused on the back of his shoulder.  One of the 
problems of the small screen on the cameras is that photos which are only 
slightly mis focused look sharp when you check them on the screen.   Judging by 
the number of photos that were front focused by a few inches, what I think I 
did on those were was use live view to focus, then move the camera back to my 
face, rather than moving my face up to the camera.  Another reason I would have 
done better with the monopod.

Among the things I hate about you Larry is that your lousy shots look
so good.  It's a nice set.  There is a definite art to making photos
taken under bad conditions into something that is pleasing to the eye.

the sparkle in his eye



I had been having some mixed feelings about my Tokina 80-200/2.8. 
It seemed like I just couldn't get sharp photos with it.  Last 
night, some friends were playing at the Trout Farm up in Zayante, 
and I decided to get a little more practice with it.  Since I did 
manage to get a few shots, that actually were sharp, even wide open, 
I realized that the lack of sharpness isn't entirely the lenses 
fault.  Big surprise, that I'm the limiting factor in the sharpness 
of my photos. 

After reading the article on sharpness in TOP, I think that a lot of 
my perception of lack of sharpness is actually lack of contrast.  I 
think that other things also come into play, such as the difficulty 
of manually focusing on moving subjects in low light.  Even with a 
split prism focusing screen.  For that matter, even with live view 
it is difficult when the subjects move faster than the latency of 
the image.  If I actually had money to buy glass, I'd be very 
tempted to look for the autofocus version of this lens, not only 
would it make focusing easier in many cases, but the shake reduction 
would work a lot better too.


While f/2.8 is as fast as a zoom lens gets, I certainly notice it 
being a lot slower than my primes.  There were several times last 
night, on TAv mode where the ISO went all the way up to 25,600.


Things also might have been a bit sharper if I hadn't left my ball 
head at home and could have used my monopod.


The other thing that I've been playing with is my post processing 
trick of dialing up clarity all of the way, up to the point that it 
nearly looks like over done HDR, but with a lot more noise. 
Interestingly, I think that when I use this trick the photos work 
best when they are actually just a bit soft to start with.  I'm 
guessing that this is because the clarity slider does something not 
entirely unlike sharpening, so if I under sharpen first, then they 
don't look quite so oversharpened afterwards.

Interestingly, 20120901-LRC70488.jpg was something like five stops 
underexposed.  I'm not sure how.  I normally shot the drummer at

Yes, there is no problem with this lens reporting the proper focal
length in EXIF.
My "shake reduction" question was the result of an unfortunate leap in logic.

I think I'm going to like this lens.

I'm curious... if it shows up in Photoshop as a Pentax-F 35-105mm,

If it is doing image stabilization for a 105mm focal length when the
lens is set to 200mm, that could definitely lead to some lack of
sharpness. I think I will see if I get better results with Image
Stabilization off and tripod mount it (which I guess I should be doing
to test for sharpness anyway!).

I don't know.

I think the camera just has to have some kind of a code to bury in
the EXIF to identify the lens & it uses the code that PhotoShop
thinks is the Pentax-F 35-105.

Don't blame the camera - it just reports the code it gets from the lens.

Some manufacturers (most notably Sigma) didn't request a code from Pentax
(presumably because there was a cost involved), so  just used the same code
for multiple lenses (usually one that corresponded to a Pentax lens that
was similar to the first lens). I'm a little surprised to see that Tokina
did this - they used to be a Pentax partner, so I'd expect them to get it
right).

As for the original query: it should be pretty easy to confirm that the
reported focal length is correct - that information is also in the EXIF.




When I mount this on my K20D, it shows the correct focal length in the 
image information when I review images on the LCD.

Re: Tokina AT-X 828 AF PRO 80-200mm f/2.8 question

2012-05-25 Thread P. J. Alling
The camera uses the code recorded in the data chip in the lens.  Having 
partially disassembled an FA and an F lens I can say with relative 
assurance that that focal length is reported by several conductive 
strips that are sampled differently as the zoom ring is turned.  I 
expect that the reported focal length is most likely correct.   The 
Acontacts tell the camera the absolute maximum and minimum apertures the 
lens is capable of, (as per Boz K mount description page).  Now I don't 
know how the following is done, but based on behavior I'd say the lens' 
on board chip sends a modification signal to the camera body based on 
the focal length selected so the camera will display and record the 
correct f stop.  This doesn't happen with A zoom lenses since they have 
no chip.

That is good to hear! (Your report, not the sound in the lens).Thanks

Yep, there's a bit of heft in that lens but the way I look at it...
some people spend good money to lift weights at the local spa while I
