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

2012-05-31 Thread Darren Addy
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.

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.

Thank you for your kind reply, John.

No, I mean that if I take the lens in my hand and roll my wrist, I can
hear a strange sound coming from about the middle of the lens.
Googling this, I found another person complaining of the same issue
and he said that he sent it in for service and when he got it back it
still did the same thing. I guess I don't care so much if the lens
performs as it should.

I'm building a little DIY LensAlign clone so I can adjust for any
front/back focus issues with it and see if I can get the truly sharp
images that people say this lens normally gives you. If not, I'll have
to assume that something is out of whack in there and send it in for
servicing.

Re: Tokina lenses and Pentax?

2012-01-30 Thread Darren Addy
This is a mystery to me, as well.
The most aggregious example that I am aware of is the Tokina 11-16mm
f2.8 AT-X Pro 116.
This lens was co-designed with Pentax and so Tokina doesn't make it in
a Pentax mount (presumably so a Pentax branded edition could be
produced) yet none is ever produced by Pentax. One might assume that
this would be because it would hurt sales of the DA 12-24mm f4. But
then why co-design it in the first place? To keep Tokina from offering
it in a Pentax mount, to the detriment of Pentax owners - is the only
answer I can come up with.

I would imagine that any agreements with Hoya would have transferred
to Ricoh, since they would have been made with the Pentax division
itself, not the parent corp.

There has been some talk of Ricoh and Tokina being competitors in more
business arenas than Tokina and Pentax were. If true, that might put
a damper on any such cooperation going forward.

Pentax and Tokina collaborated on a number of lenses in the '90s and '00s, as I

THK was merely the U.S. distributor who handled Hoya filters  Tokina

The lens ID is given by the lens to the body.

The K5 will NOT itself apply any lens correction because the K5 can do
so only for DA and FA Limited lenses.
Lightroom, though may do *IF* it has an associated profile (fot the

Tokina versions of Pentax lenses are not available in K mount. The
only way to get the Tokina is to switch to Nikon or Canon.

Also the lens is small enough that there is no advantage to a tripod
mount. It's really a very compact lens for its range.

I would second that.  I like tripod mounts on lenses that need them.
I have this lens and can't think of any need for one.  It is small
and light enough that it would only get in the way.

It seems likely to me that this is true of Hoya and Tokina, though I don't 
know where a person could go to check on it.


1) We all know that Pentax has been integrated into Hoya. Pentax Imaging is 
actually a division of Hoya Corporation.

See: http://www.hoya.co.jp/english/company/company_02_03.html

2) It is also quite evident that Tokina, Kenko and Slik are the same 
company.

See: http://www.kenko-tokina.co.jp/

Then, it seems that there is a close close relationship between Tokina and 
Hoya, which should remain different companies tough.
That does not prevent Tokina to be owned by Hoya. Heck, they even sell the 
same product with the same name! See Pro1 D line of filters, available as 
Kenko (brand used in Japan) and as Hoya (brand used worldwide).


Also, quoting from photography on the net 
(http://photography-on-the.net/forum/showthread.php?t=346581):


THK Photo Products, Inc. is the U.S. distributor for Tokina Co., Ltd. 
(Tokyo), one of the top manufacturers of converter lenses for the 35mm 
single-lens reflex camera, for all products of the camera accessory 
manufacturer, Kenko Co., Ltd. (Tokyo), camera filters of the worldly 
prestigious brand of HOYA Corporation (Tokyo). and the most copied line of 
tripods today.SLIK Corporation (Tokyo).


Having Tokina Optical Corporation as its core, a successful merge with 
Kenko Optics of America took place in June of 1993. As a consequence to the 
merge, the company has been renamed to its present name of T (Tokina), H 
(Hoya), K (Kenko) Photo Products, Inc.


As we continue to commit to our current distribution of camera products, we 
also strive to expand in the area of industrial equipment and mass media 
optical products, further providing extensive services as the leading 
optical products manufacturer in the world.


Some more hints:

If you go to http://www.hoya.co.jp, Pentax is listed as a subsidiary but not

Wikipedia and a few other sites indicate that Hoya supplies glass to Tokina,

 be
 excellent alternatives to Pentax lenses.

My Tokina 80-200/2.8 is a very good lens indeed, though my 17mm Tokina is 
only OK at best. They are capable of making very good lenses, though they 
also were capable of making some real bow-wows. I had a Tokina 24-40 that 
had so much barrel distortion that it was useless for anything other than 
horizonless scenics.

I also own a few Pentax lenses,
 that are quite bad.

Nice house or not, keep that up and you'll be voted off the island.


 How ever it seems odd that I cant find any info on the Tokina AT-X 16-50mm
 f2.8 with KAF mount. Does this not exist? And why is it priced much lower
 than the Pentax 2.8 16-50mm?

It wouldn't surprise me to find that there is an agreement between the two 
companies that on co-produced lenses, they don't get to market lenses for 
the manufacturer they are co-producing with.
Historically Tokina has made a pretty good lens, but they aren't as 
mechanically solid as first party lenses, and their coatings are definitely 
not as good as Pentax coatings.
Don't discount this, SMC is a pretty expensive way to coat lenses, and adds 
significantly to the cost of production.
I'm satisfied that the results are worth the extra money.

Not a bad little performer, especially for the (extremely) low cost.

 AFAIK, after this lens, Tokina had two (or maybe even 3) versions:
 one or two 28-70/2.8 and 28-80/2.8.
 28-80 is from their ATX-Pro line (which usually consists of their
 best, optically and by the build, lenses).
 I heard some good references about that one as well.
 
 I am not sure about the newer 28-70. I know that at least one
 version of it is ATX-Pro. (still listed in Tokina web-site archive at
 http://thkphoto.com/products/tokina/tokina-03.html ).
 They may have been a non-ATX-Pro version.
 
 I remember that somebody on this list or some other forum had mentioned
 that he was not fully satisfied with the newer 28-70/2.8, and it was 
 the one that was newer version than mine, but I don't remember which
 one. I hope somebody will clarify this for you.
 I hope I haven't confused you.

 PS. I also have Tokina 19-35/3.5-4.5, which is not as good
 (and 20-35/2.8 ATX-Pro is much better, as I heard), but still a 
 very reasonable performer. So, I have much better confidence in
 Tokina lenses then in any other 3-party brands, even though
 Sigma and Tamron have some very good lenses as well.
 Also: I am not sure if it is universal, but those ATX-Pro lenses that
 I saw had metal barrels, so they were heavier.

I've got the 28-70 f2.6-2.8 AT-X Pro in AF Nikon mount (the first AF

If it's as good as the later one, it's a good lens. I've got one with 
the 77mm filter threads in Pentax KAF mount and have been well satisfied 
with it. It's very good glass.

Not only that, my dealings with Tokina make me a more than satisfied 
customer.

The short version ... I dropped the lens and damaged the zoom ring. I 
contacted Tokina about repairing it because I didn't know if they would 
ship to an APO address and I was about to deploy to Iraq. They said yes, 
so I sent it in.

I enclosed a letter explaining:
1. I bought the lens second hand from KEH.
2. It was damaged when I dropped it.
3. I expected to pay for the repair since it was my fault.
4. APO and email addresses so they could send me the bill.

They repaired it and shipped it back to me under warranty; at no cost to me.

Hello, list-

I’ve seen some recent discussion on the list about some of the Tokina 400mm 
telephotos but have only caught a few of the messages (I usually follow the 
list via the archive which only seems to archive a small percentage of the 
messages for some reason), so I apologize if this issue has already been 
addressed…

Yes. I wonder why Mail-Archive does this.

Can anyone recommend suitable teleconverters for the lens? I have the SD if 
that makes a difference – I recently picked one up used. I see a number of 
Kenko and Tokina doublers / teleconverters available new and used. Are there 
any restrictions on which ones would work, or recommendations on which might be 
best? 

Thanks,

Rob

***

The teleconverters offered by Tokina, Tamron, and Kenko are all made by Kenko. 
Stick to 1.4x for better results.

Hi Collin: mine is the RMC version, and it is of course manual focus and 
manual aperture only, but works perfectly on everything I've tried from an 
ME up to the *ist-D.  As I said, I have found the glass good enough, having 
used it mainly at f5.6-8: you may recall my PUG shot Butterfly Dance was 
shot with it, and the displayed image is a fairly heavily cropped one, 
looking at that photo may allow others to judge it's quality.

 I've seen 3 varieties of this lens.
 The oldest of them is the RMC.
 Then came the SD
 Finally came AF and improved optics in the AT-X SD.

 Here's some general observations:
 The old RMC may be limited to the K/M mount.
 The SD can have A, or not, but also has a Ricoh pin.
 Fortunately Tokina had the foresight to make it a bump so that
 it won't interfere with Pentax' AF coupling.
 The AT-X SD is where auto-focus comes in.  I've seen no manual
 focus AT-X SD in the 400/5.6.  (Someone correct me if that
 observation is in error.)

 The SD and AT-X SD are Very Good optically.
 The RMC is much cheaper and OK optically.
 Not bad, like old Soligor.
 But imo it's worth the extra few bucks to get the SD.

optically.(Tamron and Promaster are identical.)
They are very usable but image quality still

it's quite good with short/medium teles.
Works very well with the Tamron SP90/2.8

I saw that one go on ebay... I think a lot of people underestimate the 
quality of Tokina lenses. I would go out on a limb and say Tokina 
lenses for the most part are as good and in many cases, better than 
Pentax lenses when everything is taken into consideration and that 
includes build quality. I have just completed collecting the three 
lenses I wanted most all Tokina's : 80-200 f2.8, 28-70f2.8 and the 
20-35 f3.5... (I think each and every one compares favourably to the 
Pentax equivalent and at a fraction of the cost. I recently sold the 
100-300 manual focus ATX lens which was an excellent overall lens..
Anyone looking for a great lens at a reasonable cost should consider 
Tokina's offerings.

Re: Tokina AT-X 24-200/3.5-5.6

2005-11-30 Thread John Munro

Robert Gonzales, aka Gonz, and I are testing a bunch of lenses and this 
Tokina is one  of them. Don't ask when we'll finish the testing, for we've been working 
on this project for quite a while, and it is definitely a bigger job than we anticipated 
mostly due to the number of lenses (Robert has a LOT of lenses.), and we don't have a 
permanent testing setup.

I'll give you my opinion. The lens is well built - only the lens hood has a plasticky feel. 
Considering the focal range the lens is quite compact and light. I use it for snaps so 
I'm not looking to produce large prints from it. I was involved in an auto accident, and I used it 
to take documentation photos with Kodachrome 25. The insurance company enlarged what I shot to 
20x30s and one 40x60. I was impressed with the quality. Yeah, the resolution and tonal range is 
probably not up FA 80~200/2.8 quality, but I will guess that it can favorably compare to the 
cheaper Pentax zooms and maybe beat some of them. If you care for more info, drop me a personal 
email and I'll gladly respond. Otherwise, please patiently wait for The Gonz Report.

It seems to get pretty good reviews (better than a lot of the more common
28-200 super-zooms).  Thanks.

Fred

That could get to be an expensive lens testing methodology. :-)

Hi Patsy,

Well, if the DS is here, that and a couple-three lenses.  If not, maybe a
Leica or two and a couple of lenses or an MX and two or three lenses.  But,
in truth, if the DS isn't here, I won't know for sure until much closer to
the date.  Heck, I may even decide to bring an LX or a Yashicamat.

Just got back from a two-day jaunt to Tijuana and back. Not really a  
photographic trip, but I did carry the camera and 20-35/4, 35/2,  
50/1.7 and 28-105/3.2-4.5 lenses. With the Pentax gear, this all fits  
in a nice, small, light bag. Such a difference from trying to carry  
my 10D in a similar manner!


All but 10 of the 80 exposures I made were made with the 20-35. (The  
other 10 were made with the 35/2 and 28-105; the 50 never got out of  
the bag.) This is a perfect focal length range for so much of my  
photography, and the optical performance combined with the physically  
small, non-intrusive size is a bang-on winner for me.


Switching to the FA35/2 AL, yes, the 35mm prime is a better performer  
and made a couple of exposures that would have been difficult with  
the f/4 lens. Only 1 stop faster on the Tokina compared to the  
FA20-35/4 isn't enough to warrant the additional size and weight,  
even if the Tokina is a good performer, IMO.

Specs can be misleading. The Tokina is the smallest 2.8 wide zoom ever
produced, and for the speed and reach, it's quite small.Unfortunately,
the samples I have tried were quite bad on digital, with lot of purple
fringing and other failures. I have heard good things about it on
film, and one news shooter quite liked his paper's, so maybe it could
be worth a look. Perhaps it's sample variation, or whatever.

I tend to agree with you, but I've just gotta see for myself.  It's not
just the extra stop that's of interest, although that's the prime
consideration, but other factors such as the characteristics of the image

Shel,

In addition to seeing Godfrey's 20-35, would you be interested in seeing a
Tokina 20-35/3.5-4.5 autofocus lens at the Pixel Party?  It's not the 2.8, but
it's mostly metal constructed, as far as I can tell and quite a bit heavier
than my other Pentax lenses.  As far as image quality, you will have to decide
for yourself.

Like Godfrey, I find myself using this focal length a lot in addition to the
28-105/3.2-4.5 now that I am using the digital body.

It's an excellent lens.  I guess $300 AUD (about $225 USD) is a decent
enough price for it, if it's in such good shape, although I have seen
apparently good specimens go for a bit less.  You might want to make sure
it's a Ka-mount lens, though - this model is available both in A and in

They may say what they want, but I have handled both the 2.6-2.8, 2.8
SV (yes, it features PRO denomination as well). The 28-80 I have
only handled once, and not shot any photos. Simply, there is
difference in mechanical construction and materials* once you compare
the SV and non-SV versions. SV was previous line of Tokina's consumer
lenses, the SV PRO is a merge of the two?!? Optically, I have seen
better results from the non-SV versions, esp. at full aperture. That
said, it's not a bad lens at all, just not as great as the earlier
(and quite a lot more expensive) Tokina 2.6-2.8 or 28-80 probably.

*: the zoom rings are plastic in the SV version. Like with most partly plastic
lenses like Sigma 70-200/2.8, once you squeeze the zoom ring a bit, it
turns much less freely compared to a good all-metal zoom. More of the
outer shell is plastic too. The design looks the same, but the
materials differ, just hold them in hand :)

Hope that helps.

Re: Tokina 80-200 f/2.8 questions

Hello David,

When I got this lens, I had quite specific needs.  I already had a
Tokina 80-200/2.8.  I found that lens to not really fit me.  For my
wedding work, it was too big and bulky to use comfortably - I replaced
it with an A 70-210/4 and for my baseball work I needed a lens that
went to at least 300 and could be used at f4 with good results.  There
is always the teleconverter route and I tried that first.  Just didn't
like the results all that much.  Not to mention that AF is slowed down
a bit when having to go through the converter.  About the only time I
use AF is for this baseball stuff.  So the only lens that would really
fit my needs was the Sigma 100-300/4 EX.  I can say that through
testing, I am satisfied with it's wide open performance.  Overall,
optically it is very good.  The tripod collar is very nice and quick
to switch the lens orientation and the hood is very good - bayonet
both ways so can be stored on lens when not in use.  Build quality
seems to be quite good - doesn't have that indestructable feel of the
Tokinas though.  Both zoom and focus are internal so the lens body
doesn't change length at all - very usable that way.

So yes, I would recommend it, if that is the kind of thing you are
needing.  I generally shoot it from a monopod.

Igor,

I used to own the manual focus version (with A, ha ha) of the 2.8 and now
have the AF version.  And I also have the Tokina AT-X 80-400/4.5-5.6, which
is also an AF lens.

The 80-200 AF is notably smaller then the manual focus version.
Optically, I liked the manual focus version better.
But both are excellent.

The mechanical feel of the two is a toss-up.  The MF version is easier to
get my hand around, but the AF version, being a little smaller, is easier
to hold in general.

Everything I've heard about the recent Sigma offerings has been
positive.  They needed, badly, to put out some good stuff to rebuild their
reputation.

The 80-400 is easy to handle.  It get's soft when past about 380mm.  And
like everything else Tokina, stop down the aperture one stop for maximum
sharpness.  It's a fine lens.  One showing significant outside wear went
for a bargain price on eBay last week.  I hope some PDMLer got it.

The 80-400 is a little difficult to use with AF in low light 
or out around 400mm.  So use it MF and you're fine.

The 80-400 AF is faster on the DS than the 80-200/2.8 AF response.
I wonder if Pentax needs to add some dynamic adjustment to light sensitivity
or contrast level to the AF system.  The 80-200 is great, but does tend
to hunt a bit.  The 80-400 didn't hunt much at all.

The older 80-400 has no tripod collar.  The new II version does.  With
any of these lenses, that's important.  Since we don't have anything
resembling IS yet.  But alas.

And all of your options are $  (Pentax / 2).

Whatever you get, they all produce excellent images.  Don't worry about
that side.  Just get one and shoot.  You'll be happy.

Excellent lens. Image quality also excellent. Pretty
hefty but not too unwieldy. Sold it only a couple of
months ago. It became pretty much redundant when I
bought a 100-400 (for EOS)

I also used to own Bruce's Tokina 80-200 f/2.8 which I
quite liked too :-). I even bought a second copy in 
EOS mount. Now I have neither. They were sold to fund
other purchases, not because I wasn't happy with the
quality of the images.

2005-08-19 Thread Joseph Tainter

Is this the current one? If so, it tests less well than two others:

Tamron 28-75 f2.8
Tokina AT-X AF Pro 28-80 f2.8

I have the Tokina 28-80, and can attest that it is very sharp but heavy, 
and can flare if shot into the sun. The Tamron is also very sharp, 
lighter, and less expensive.

 Message-Id: [EMAIL PROTECTED]

 Does anyone have the Pentax version of this lens? I'm wondering how  
 it compares to the much more expensive and heavy Pentax FA 28-70  
 F2.8. The Photodo rating for the Pentax is 3.5 compared to a 3.1 for  
 the Tokina. I've had my eye on the FA for some time now, but for its  
 price I could get an FA 24-90 plus maybe a couple others on my list  
 (16-45, 50-200, etc).

 Thanks,
 Jay T


I have AT-X 28-70 PRO f/2.6-2.8, purchased back in 1997, which 
I believe is the previous version of this.  This is a very good lens, 
and at that time it was tested very well against other brands. 
I don't remember details, but my impression that it was rated just
below the counterpart from Pentax, and way above the similar lenses
from the Sigma and/or Tamron (I don't remember who had what at that
point).
Overall, my lens is very good. I think it a bit soft on with the 
aperture one open, but half a step closed down it seems to be alright.
It is rather heavy and large in size, but to me it is worth hauling
it around.
With ZX-5n and *ist DS it is usually quick to focus (if the manual
focusing ring is disengaged). Maybe not as fast as my Pentax SMC FA 50/1.7,
but, still fast enough.

Again, I am not sure how the new lens is compared to the old one,
and what is the difference between the 28-70/2.8 and 28-80/2.8,
i.e. which one is the continuation of the 28-70/2.6-2.8 design, if any.
I was curious about that myself.

FWIW,

If you don't want or need AF, you can get either the Tokina SD
or the Tamron SP 80-200mm F.8 Lenses for under $300 in nice shape
used. They are both excellent lenses...

Hi All!

I've been using a Tamron 70-300 f/4-5.6, but now I am thinking about
replacing it with a better quality lens. Recently, the limitations of this
lens appear in the images a bit too often.

Pentax 80-200/2.8 appears to be out of my budget 
(unless some kind soul would sell it to me at some mid-triple-digit price).
:-)

So, I am currently looking at Tokina AT-X 828 AF PRO (80-200, f/2.8) It is
still expensive (~$610-$60~=$550), but ...

Does anybody have experience with this lens?
Has anybody used it with *ist DS/D?
Are there any comparative tests online? (I tried to find, but couldn't so
far)

Also, - I see that there is a $60 rebate for this lens.
Usually this means that the price should go down soon, most often due to a
new lens coming on the market. Has the been any talks of Tokina going to
bring out new lenses, 
maybe in a digital line?

Related suggestions are greatly appreciated (am I overlooking 
other alternatives?).


Thanks in advance,

Igor

Hello Igor,

Here is a link to some shots taken with that lens:
http://forums.dpreview.com/forums/read.asp?forum=1036message=14636626

There is a link in there to more shots.  In answer to the thread, the
photographer indicates that they were shot with the lens in question.

At one point I owned this lens.  The two issues I had with it were
that at 200mm and f2.8 it was too soft.  It sharpened up by f4 or
shorter focal lengths.  The second issue was that for most of my use
(wedding/portraits) it was just too big and heavy.  I finally ended up
with a Sigma 100-300/4 EX for sports shooting on a monopod and the A
70-210/4 for my wedding and portrait work.

The rebate has been going on for quite some time now.  I don't really
get the feeling that Tokina is trying to dump them for a new version.
Most things I see and read lead me to believe that the Sigma
70-200/2.8 EX is a better lens, at least optically.

I can say that if I needed that type of lens again, it is one that I
would consider, along with the Sigma.

HTH,

Bruce

Works best on the muggers if you remove the hood first. Don't want to

Works nicely for frightening small children and old ladies. Especially

Tokina made a really good 80-200 f/2.8 manual focus lens for quite a while.
I think it was an SD lens. Mine doesn't have an A setting, which is too bad.

the too bad part is the cameras fault not the lens's.
Put the shame where it belongs, K/M type lenses are perfectly
capable of everything but program AE and shutter priority
AE ( neither of which are/were very popular ) but the PENTAX
DSLR is ignoring their capabilities... Its not the
lenses fault at all...Its PENTAX DSLR fault for not
utilizing ALL the features of the K/M type lenses...
(specifically not sensing the aperture ring setting cam)
