Andre, the single most important thing to know is that they come in at least two grades. The lighter and lower cost ones are OK for the X-ray units used on carry-on baggage. They are not OK for checked baggage, which may be subjected to megadose X-rays at some airports. I bought a bag that holds about 20 35mm rolls (removed from the boxes) and my film survived just fine after at least four doses. It cost about $35 in a camera store. If I can figure out where I put it, I will post the brand name. I would avoid the cheap $10 models from discount stores. There are others capable of withstanding the megadoses that checked baggage can be exposed to, but they cost more.

Andy, you can estimate the 35mm lens equivalent to any 6x7 focal length, simply by taking half of the 6x7 focal length. thus the 105mm Takumar is equivalent to a 52 1/2 mm, or roughly normal, lens, for 35mm format. The 90mm Takumar would be equivalent to a 45mm lens, which actually is more "normal" in terms of matching the film diagonal. Having used the 105, I can tell you it is very sharp!
The basic Pentax 6 x 7 is really quite good. About the only complaint I had was that when the battery dies, it will probably do so in the middle of taking a picture. The mirror hangs up in mid-swing, KAPUT! You lose the picture and the frame. Maybe they've improved this in the current model. Even with that, it's a good camera to start with. In other respects, they are easy to handle, aside from the weight. Just like a 35, only bigger.

I use my 50mm CF for landscape and cityscape shots. When shooting
structures like bridges with fine detail, I find the lens is very
sharp in the central region, becoming best around f/8. However, the
corners remain visibly soft until I have stopped down to around 11
and a half to 16. f/22 gives no further improvement.
The 50mm FLE is said to be better at medium and close focus because
of the adjustable floating elements. My question: does the FLE give
corner to corner sharpness that is improved over the 50CF at focus
distances close to infinity? Does it achieve corner to corner
sharpness at a wider aperture than the 50CF?
-
I have the 50mm CF. The lens is basically sharp, but to extend the sharpness to the edges, I have to stop down to f/11. To be sharp into the corners, I need 11 and a half to 16. 22 offers no additional advantage. This is for infinity focus. The central sharpness starts to deteriorate, though, stopping down smaller than f/8. I would be interested to know whether the FLE performs any better at infinity than the 50 CF. Any comments?
-
John, Iv'e never been disappointed with the focus on my SWC. The depth of field is so great, that if you just use the DOF scale in conjuction with a little judgment about estimating distances, you won't go wrong. I love mine. Buy it.
Regards, Bob

Tony, what is this about? DO= Depth Of (field)? That's what the
diagram indicates. Are you asking a question? Or is this an answer
to a question. What's gif? general illumination field? goodies in
focus?

David, the "whiting out" thing with the M6 is not to be taken
lightly. Being used to my M2, it's frustrating as hell to not be
able to focus in the presence of backlight. It is the reason that an
M7 is needed--aproblem yet to be solved. I am sorry I sold my M3,
and glad I still have my M2.

Al, when I was 12 I started using my dad's black-paint Leica model D,
also know as the Leica II. I seem to remember the lowest couple of
shutter speeds were 1/20 and 1/40, or something like that. 50mm
uncoated elmar. One day he left it in the car for a few seconds and
someone stole it. The insurance company bought him a IIIf, red-dial
I think. I used it until I was about 20, when I bought my own M2. I
never experienced the model D or IIIf as hard to load. It was what I
had. I loaded it. It worked. At 14 I shot a picture of Sharon, the
most beautiful girl I had ever seen, from my seat next to her in
biology class. Only took a second, nobody noticed. I wish I had this
camera back. (serial #685475) Also used it to photograph my Air
Force friends for several years. It is a very handy camera, but
lacks a built-in meter, of course. When my dad started letting me
use it, I think the speed of Kodachrome was 8. I think the basic
daylight exposure was 1/50 at 6.3, if memory serves. We had a Weston
meter, in case it was needed.
<p>
Unless you do flash photography, you wouldn't have to have a IIIf. I
always sort of liked the IIIc. I don't think it has flash sync (who
needs it?) But it is improved over previous models: die-cast frame,
one-piece top cover. I don't remember with which model they added
the ball bearings.
<p>
I think I would go with the 50mm collapsible Summicron. It was
available in thread mount. After all it has always been the world
standard.
<p>
There is a question in my mind about whether one would be better off
with an old Leica, or a a modern compact. I am a little partial to
the Olympus Stylus. My girl friend, a philosopher, came back from a
philosophy convention in Russia with great shots of the Kremlin, and
shots of Doestoyevsky's home in (I think) St. Petersburg, as well as
some relatives in the Ukraine, all done with her Stylus. But I
digress. I have also been hankering after a screw-mount Leica. So,
let us know what you decide!

Jim, there's another thread on this, posted by Joe Buechler. Also,
someone (but I can't find the thread) posted a similar item on
another small part, and the responses were to the effect that Leica
mails them to you free, and you glue them on. Me, I haven't lost one
yet. Guess I'm not using my Leicas enough.
<p>

Jim, I'm with Keith. I checked my 50 Summicron and found with the
lens focused to 10 meters, at f/8 everything from 5 yards to infinity
will be in acceptably sharp focus. Fire away!

I've tried a few, but they all have problems. Either you can't search through them by subject, or else you can't interact on them (like the ListQuest archive). The Majordomo things seem to require a PhD. in computer science to figure out!
<p>
Any suggestions?

David, If you get anything wider than a 28mm, you will probably
experience a sort of "hole in the middle," or gap, between it and
your 50. then you would feel the need to fill in the gap with
another wideangle lens. I feel that 24-35-50 makes a good
progression. And 24mm is wide enough so as to seldom need anything
wider. I agree with everyone who gave high marks to the 35mm
Summaron.
<p>

I looked at the website Al Smith cited (I should have done this in
the first place). The lens has 6 elements in 4 groups. If you have
access to the Leica M Compendium, take a look at the 35mm Summicron
on page 51. Now, take away the thin lens just to the right of the
diaphragm, and the remaining components, I feel pretty sure, would
bear a close resemblence to the 40mm Summicron.
<p>
That's the best I can do. Hope it helps.
-
A point to note here is that schematics published over the years, in
several books, such as The Leica Compendium, or the Leica Manual, or
Photgraphic Optics by Cox, show that the 50mm Summicron doesn't even
resemble itself too closely in its various versions. For this reason
it might be difficult to divine much about the 40mm, or how it
compares to other Summicrons. I should imagine it probably is a
gaussian design, with a pair of cemented groups, each having a deeply
concave surface facing each other from opposite sides of the
diaphragm; possibly a thin lens airspaced and interposed between one
or both of those concave surfaces, and the diaphragm; and single
element positive components for the front and rear elements. This is
the basic setup of the 35mm Summicron of the time period. But, then
again, the 90mm Summicron doesn't adhere to this type of formula, and
this too makes me question how much we can figure out by examining
the schematic. Why not ask some users to comment on the performance
of the 40? I think it's supposed to be good, but I've not used one.
<p>

This actually depends on your vision, not the camera. If you have
20/20 vision, or better (some people do) you do not need a diopter
correction. If you wear glasses, and the optometrist gave you a copy
of the prescription, look at the entry under "spherical" for your
dominant eye (the one you look through the camera with). If you are
right-eyed, look at the figure for "O.D." which means "right eye."
It might say something like, '-1.5" or "-3.0" if you are nearsighted,
or maybe +2.5 or so if farsighted. this is your diopter correction.
It may also have an entry under "cylinder" such as "-1.0 at 100
degrees" and this is your astigmatism correction, which could be
included in a custom ground corrective lens.

Steve, according to The Source Book: Kodak Ektagraphic Slide
Projectors, Eastman Kodak Co., 1984,
"For most viewing purposes, pictorial slides made on properly
processed Kodak color films will be acceptable through 3 to 4 hours
of total projection time. This is true when the slides are used in
an EKTAGRAPHIC III or EKTAGRAPHIC slide projector that is equipped
with a tungsten-filament lamp and had unrestricted air circulation,
even if the projector is operated with the power-selector switch set
at HIGH." (p.154).
<p>
But, this is only a generalization, because slide life is roughly
proportional to light intensity. It is difficult to give an exact
figure, because "there are too many variables, such as proper
processing, adequate projector ventilation, ambient temperature, and
so on. However, the film types . . . does not make a significant
difference . . ."(p.153)
<p>
And note: > ". . . [slides] will change somewhat less if projected
continuously for a given time rather than intermittently until the
same projection time is reached." (p.154).
<p>
Hope this helps.

Just as a pure guess, it might be that they didn't include a 24mm
frame on the .58 model because maybe the 24mm lens, with hood, cuts
off too much of the right side of the viewfinder to be useful. I
can't think of anything else to explain this omission.
-
Wladimir, I had a camera, about 1952 or so, that used 35mm film
guage, but with sprocket holes only on one side, as you suggest. I
believe the film size was 626, if memory serves. I think it was a
Kodak Pony.
<p>
Now, as long as we're all being amateur camera designers, how about
this: 20th Century Fox once developed a deluxe version of
Cinemascope (anamorphic widescreen process) which used 55mm film,
supplied by Kodak. How about a Leica-type camera in this guage,
using approximately a 44 x 54mm image size? Same idea as the Mamiya
6x7, but in a 645 format with horizontally travelling film so the
camera would retain Leica-type ergonomics.
-
My favorite is: M6 with 50mm 0r 35mm lens, Fast film (e.g. Tri-X),
and available light. With some good daylight coming from a nearby
window, I have my best chance of getting a natural shot with a
gentle, non-harsh light. Enough light on the eyes is really
important. Flash looks plastic and artificial to me. I don't think
Eisenstadt used a flash for his picture of Albert Einstein.
<p>
Just my thoughts on the subject
-
I think Michael's comments about the difficulties of scanning pushed
film apply equally well to printing. Extending the development time,
in an effort to increase negative density, leads to blocked up
highlights which reduce the printability of the negative. Pushing
Provia 100 leads to higher contrast and inky-black shadows.
<p>
So, what of Kodak's claim that T-Max films are easily pushed, for
example in T-Max developer? I think one gets away with it a little
better, with T-Max, because of its very good shadow speed. I can
readily see that T-Max really does have more shadow detail than, say,
FP-4, to name one where I've made this comparison. Kodak even
recommends a normal development time when "pushing" (underexposing) T-
Max by one stop. Even so, you don't get as much shadow detail as if
you had not pushed. But the loss is minimal at one stop under. Only
thing is, T-Max tends to be a bit flat, IMHO, in many developers,
including T-Max developer.

Ron, I have both the collapsible 50 and the Summicron-M. The latter
is not the current version, it's the one with the focusing tab. I am
hard pressed to see a difference in sharpness between them. Small
architectural details look about the same when comparing at the same
aperture. I limited my test to f2, 2.8, 4, and 5.6, so as to keep
the shutter speeds high with Velvia and Technical Pan. Now, when it
comes to contrast, the M is contrastier. Shadows are darker, not
filled with diffused stray light. So, I guess the question is, if I
can barely tell the oldest from the latest, how much difference can
there be between the oldest and the second-oldest?
<p>
Just something to ponder . . .

OK, how about $75 for a hood for the 35mm Summilux? I wanted it . . .

NHP, let me jump in here one more time. It sounds like you want to
do what Henri Cartier-Bresson did, capturing "the decisive moment."
He used a Leica, you know. I don't believe his lenses were anything
too fancy. Probably 35mm and 50mm lenses available at the time.
Maybe Elmar, maybe Summar, Summaron, who knows. He learned to use
them to meet his objectives.
<p>
Now consider the Life Magazine photographer, Alfred Eisenstadt. You
know, the one who took the picture of the sailor kissing the nurse in
Times Square. Another Leica man. "Eisie" said that whenever he felt
tempted to buy something, he always asked himself whether it would
really improve his photograpy. Usually the answer was "no" and he
didn't buy it. He said he couldn't justify a new Gadget bag for that
reason. Eisie talked, not about Leicas, but about the importance of
developing a rapport with his subjects.
<p>
Let's move on to W. Eugene Smith. He shot mostly with cameras
borrowed from friends. Nothing fancy. Yashicas and stuff. The
country doctor. The two kids walking down the tree-lined path. The
death of Gus-Gus. According to the latest issue of Aperture, you can
get five prints of Smith's work in a nice little cloth-lined box, for
only $1500.00.
<p>
Now imagine the following scenario. A painter goes to Claude Renoir,
and asks him whether he should trade in his 35mm Sable brush for a
35mm camel's hair; or whether a 28mm or 50mm brush will make him a
better, more famous painter. What do you think the master will say?
<p>
A driver in New York City rolls down his window, and yells to a cab
driver: HOW DO YOU GET TO CARNEGIE HALL? The cabbie yells
back, "PRACTICE! PRACTICE! PRACTICE!
<p>
Best Wishes,

Yep. That's about it. Two frames to be conservative. One frame if
you like living on the edge and pushing the edge of the envelope.
