Hi Frank,

first I have to say sorry because I didn´t send you further infomation
about the FA24-90 so far :-(
But there is hope, I have some special testshots
(with FA77 and FA43 :-) ) in front of me now.

Yes the MZ-5 will warn you, but due to the "big" (in diameter) lens
it will warn you if you go wider than 50mm because you might get a
shadow of the lens.

Ciao

Re: Need K2 instructs

[Terence Mac Goff]

Hi Peter.

I don't actually have the book itself (I used to, but have no clue where it 
is). However, if its a particular function or problem you are trying to 
track down, please feel free to shout, and I may be able to help.

As a complete aside, from memory, you have a fairly good stock of lx bits, 
and I was wondering if you had any of the new sg screens in yet?

Thanks,

T.

Re: Roberts tech manuals

[Scooterman]

I saw a website where someone had made .JPG's of every page for the
ME-Super & a single .HTML to access it all.

I like the idea of .PDF files (cuz they're small & few bother to get the
proggie to MAKE/alter PDF files) 

Since you've already made several manuals available, what do you think
the practicality would be of using my PC-cam to take pics of a manual &
then zip em all up as a PDF file?? (I've got the full-tilt ACROBAT 5
pgm).

Too big? Waste of time? Neat idea?

I've got cherry copies of the Program Plus & ME-Super owners manuals ...
plus I think I can talk my tech into letting me have access to his
library. (I think.. we'll see).  AND a decent copy of the PENTAX
Accessories handbook (@ 1982 ver).

Re: FA-1 finder innards, final resolution.

[Shel Belinkoff]

César asked:

> [...] but how do I talk myself back into getting an FA-2?

Beauty and simplicity, César.  The lines of the FA-2 finder are pure
and simple, uncluttered by the hot shoe, and gives the LX a look more
akin to its Spotmatic and earlier ancestors.  The LX looks cleaner and
less cluttered, more in character with the straightforward
mechanicals.  The FA-2 finder connects the LX to its history.

In principle something like this is possible, but you would have a hard
time getting it accurate, as all measurements of distances would have to
be relative to the primary and secondary principle points of your lens.
And there positions are generally not known.  But still, you can find all
the relevant formulas in
http://www.photo.net/photo/optics/lensTutorial.html>.  One
possibility that might be more reproducable is to use the closest focusing
setting your lens allows and take a picture of a ruler.  Afterwards, you
photograph all flowers at exactly this focusing distance and compare the
image size of the ruler with the image size of the flower.  No need for
math containing unknown variables ...

FA-1 finder innards, final resolution.

[Matamoros, Cesar A.]

Thank you Steve L. for giving me the encouragement to take the FA-1
apart.  The rattle was the diopter correcting glass.  It was fun taking the
whole assembly apart.  H, how do all these washers go back in?  Is it
efficiency if you have parts left over?

I ended up having to do three trial runs of placement of the diopter
glass and the gearing for the diopter dial, but the finder is now allowing
me to focus properly.  It is great having a couple of extra finders to check
your work.

Thanks again, but how do I talk myself back into getting an FA-2?
Wait a minute, with this group enabling is always just a keystroke away.  I
only have the three FA-1s, so I really should get the FA-2, I rarely use the
hotshoe since I normally use the AF400T with them.

César Matamoros II
Panama City, Florida

P.S.  By the way, I was in a restaurant and decided to try out the AF on the
MZ-S with the 77 on a neon sign up on a wall.  I basically just placed the
camera on the table for support and roughly pointed it in the proper
direction and fired.  Nice shot.
I put the 77 on the LX and did the same placement, THEN, I took off
the finder and composed and focused using the focusing screen.  Nice shot!
It is probably only the third time I have ever done that.  Nowadays people
just look at you and say REMOVABLE finder?

Re: ME Super noise/filters & misc

[Scooterman]

The only noise mine makes is the rattle from the plastic film "grippers"
on the film take-up spool.

One thing I did notice, the auto-timer spring seems to be quite tired.
I spoke with my tech (last CLA) & we pretty much agreed that it's
probably a teensy-tiny spring (much like a watch spring) that'll be a
BEAR to change & a new one (if it can be had at all) probably won't be
that much of an improvement. I don't use it (never have)... but how's
the springs on other cameras as old fairing??

Someone was kicking it abt filters recently
While digging out my ME Super from its gear bag (more museum than
working bag) I "discovered" a stack of 49mm PENTAX filters...
("So THAT's where they got off too... I thought I had more somewhere!")
They weight a TON compared to some Hoya's I've got... esp the PL's

Running (dancing) to the PENTAX website, I didn't find any.
Does Pentax still make em or have they surrendered the field to the
competition??
~
And while I'm here

While perusing the "junk" table of a camera shop (must be a year ago
now)... I picked up an AF 1.7x adapter. Supposedly one can mount it to
their AF-Pentax & use their M & A style lenses in AF mode.

Anyone have any experience with this item??
I don't own an AF, but for the $12 they wanted for it (NOS) & spotting
the yellowed $150 price tag, I just couldn't let it pass.
Is thing actually useful or should I have just rolled the $12 up &
smoked it? 
Think it'll only work on certain AF's... or right down the line to the
ZX-5N??

NO!  Denatured alcohol will leave no residue, but isopropyl will.
And, many plastics are harmed by alcohol.  Keep it away, just
to be safe.

RE: [O.T.] Scanners

[Rob Brigham]

Epson 1640su Photo is about as good as it gets, although not sure what
the price is in the US.  The 1240 should be pretty good, but I think you
have to buy the hood separately which may almost cost as much as the
1640 bundle and is less dpi.  I think 1600 dpi is about as low as you
should go for 35mm negs and only then at a push...

RE: focal lenght

[Jostein Oksne]

Mauricio,

Stan Halpin forwarded your message to the Pentax Discussion Mailing List,
from which I reply.

If I got this right, you wish to take photos of flowers at exactly 1:20,
then make a grid that you can print onto the slide afterwards to measure the
size of the flower.

I advice against using this method because the accuracy will be pretty low.
1/10mm * 20 is 2mm error margin. If your small flowers are eg. 10mm, that's
an error margin of 20%. That might be okay, but it's definately not
scientific standards.

May I suggest another method for you to consider:
Make a grid design that you can use in the field, and place right in front
of the flower. Like a tennis racket, only with a finer grid. Then photograph
the flower and the grid together. Then you can measure the size of the
flower correctly independent of scale in the photo. Your accuracy will only
depend on the accuracy of the grid.

You could also photograph the flower with any object of known size. Eg. an
ordinary liner or ruler, or a cylinder (filmbox etc.). As long as you know
the size of the object, you can calculate the size of the flower:

  Oi/Or = Fi/Fr
or
Fr = (Or*Fi)/Oi

where
Oi = Object size on image
Or = Object size in real life
Fi = Flower size on image
Fr = Flower size in real life

If you project the slide on the wall and measure there, your accuracy will
be pretty good.

Hope this helps?

Re: Me Super noise

[Anthony Farr]

Loose rewind shaft?  Or loose film speed setting/compensation dial?  Perhaps
even something in or around the battery chamber.  There's not a lot of
mechanical content on this side of the camera, apart from the shutter and
mirror box, so I think these are the easy ones to investigate.  Beyond that
it's a tech's job, I reckon.

Is the rattle light (tinny or tinkly) or heavy (thud or thunk)?  From the
top or the bottom?  Does it still rattle when the camera has film loaded?
All these are good indicators of the problem.

Anthony Farr

Re: The MZ-S; a batteryholic?

[Anthony Farr]

It is common for studio flashes to have a full power duration in the region
of 1/100sec.  Using a shutter speed shorter than that could result in uneven
exposure across the travel of the shutter, because the closing blades would
commence before the flash had quenched.  It is not a fault of Pentax but a
phenomenon common to all brands of camera where a focal plane shutter with
X-synch shorter than 1/100 is used.

Anthony Farr

on it it goes to 2:1it is alright at 8~11.
but the build quality is no were near the other lenses.

I have experiance with the SMC-M 100mm 4.0 manual focus lens. If you intend is to use 
this lens only for macro it is the best choice.
you can use the focus-trap on your camera. this lens is build to last and costs about 
200 dollars used.

I recently bought the SMC F 100mm 2,8. Yes I like the extra speed and the AF for 
normal distance pictures,
but the focus trap does not work since you can not put the lens to manual focusing!
I should have bought the SMC FA 100mm 2,8 which does has an extra switch on the lens 
to put it in manual focusing mode.

But in the end, macro lenses are used around aperture 11 and every macro lens is 
optical OK by than!

Classification:



Anyone compare the FA 100mm macros?  I see there is a big price
difference between the F3.5 and F2.8 versions.  How do they compare for
sharpness?

Also, how do they compare to third party lenses eg Sigma 105 EX?  Flare
resistance is not really an issue for this lens as it will not generally
be used in condidions where this is a factor.

[O.T.] Scanners

[mike y.]

Well, just in time...  My PrimeFilm film scanner crapped out just when my 
tax rebate showed up (I'm thinking it's a conspiracy).  So, I'm looking for 
some new hardware.  Can anyone tell me if it's possible to find a flatbed 
scanner with negative/slide adapter with decent resolution for under $300?  
Any recomendations?

Re: The MZ-S; a batteryholic?

[Francis Tang]

My mum picked some cheap, "Kirkland" alkalines.  In the pack of 12, I
remember two were just "dead".  The first two I picked out of the pack
included a dead battery - naturally the device (Walkman) didn't work.
Perhaps you were just very unlucky and picked three dead batteries in
your three attempts?

Subject: focal lenght

Dear Friend:

I work with plants and i am needing to build a ruller that allows me to
determine the size of small flowers. I need a ruller that measures 1/10 mm.
I decided doing a reticule model at 1:20 and taking a picture and using the
design printed on a slide as a ruller. I need to know the relation between
the film position, the focal lenght of the lens and the object distance. I
will be working with a 80 mm lense and I will place the object at 1,6 m from
the camera in order to have a 1:20 scale.

thanks in advance for considering my inquiry

Mauricio

Your suggestion makes sense to me. 

Since max sync speed is the minimum amount of time the shutter can stay
entirely open...
Maybe the max sync speed is not enough time for the light meter logic to
process more than one flash? Eg. if it fires the main flash first, breaks it
off at correct exposure, waits a few milliseconds for the light to die,
"resets" the OTF meter sensor and then fires the other flash. 


Well... I'm just speculating...

Re: OT-- BRAZIL

[Albano_Garcia]

You must try caipiroska (made with lime and vodka). It rules, man.
All kind of daikiris too.

Drunk Albano (from neighbor Argentina. In wines we rule)


The caipirinha became popular and kind of trendy in New York City about
1994 or so. The trendiness lasted until we all figured out that there
were better things to drink than something that tasted like sweetened
kerosene. The trend disappeared fairly quickly and I haven't seen that
stuff here in many years.
But last year I went to the Dominican Republic for a vacation and they
were serving them at the bar at the resort I stayed at. Tried one again,
hoping they had improved the quality of the kerosene. No such luck, so I
went back to drinking something else.

Re: Super Program metering problem.

[Jody]

On that topic:
1) I have a "Standard Camera Cleaning Set" made in
Japan with blower brush, lens tissue, cotton buds, and
cleaning solution. What is the cleaning solution
likely to be? Is it safe? I think the diagrams show
that you can clean your lenses with it.
2)I "acquired" a few isopropyl alcohol wipes from the
hospital where I work. Are these safe for cleaning
say, Spotmatic internal meter contacts? Or lenses
(outside only)? I assume the alcohol would just
evaporate and not leave any residue, is this correct?

Jody.

Re: Super Program metering problem.

[Allen Murray]

Mark,

Thanks again, I was actually already at your site. You provide a great
service with these manuals. Would there be any place for the Super Program
owners manual there? The reason I ask: I've got my original owners manual,
Adobe Acrobat and a scanner. If I created the PDF would you like to put it
on the site for others? Any tips on creating the PDF for the site? The
manual is in reasonable shape with a couple minor water stains and squashed
mosquitos and black flies. What about copyright?

More MZ-S flash (was: The MZ-S; a batteryholic?)

[Alin Flaider]

  Diving deeper into the mail pile:

Max wrote:

MM> Has any owner use theirs with studio flash yet?
MM> I ask this because the manual recommends lowering the shutter
MM> speed to a full stop less than the maximum sync. speed when

MM> A mistake surely.

  Max, I don't own neither the MZ-S nor the new flash, but here's my
  take.
  I don't think it's a mistake - actually it is the camera that should
  automatically set a lower speed than sync speed no matter if it's in 
  auto or manual. 

  I suspect the reasons are the same why you need a longer speed when
  in contrast control mode:
- the camera has to distinctly talk to each flash due to the
serial nature of the comm link. 
- also the camera should  measure/time each flash discharge
independently to allow for selective compensation.

  Perhaps this sequential approach together with the corresponding
  computing requires double the sync time (although if the PZ-1p logic
  can do it in 1/125, why MZ-5N needs 1/60 !?)

  Add for MZ-S the pre-flash initial stage where it measures each
  flash by itself to determine how much it contributes to the overall
  lighting, and you get a pretty impressive procedure that may justify
  the additional time expense.
  Eh, just my guess anyway...

  Servus,  Alin

They're free. I ask people to send me copies of any other Pentax service manuals

I have used this method quite sucessfully with my

for that matter is the LX (correct me if I'm wrong).
