Hi,

it might be worth mentioning, for anybody who hasn't used a Leica,
that, unlike an slr, the image size in the viewfinder doesn't change
when you change the framelines. So whatever lens you have on the camera
the view through the finder is the same. The framelines are there
simply for framing the subject and the longer the lens, the smaller
the framelines.

No, it is not.  
 
Try using a zoom and seeing what's going on outside
of the frame.  With an SLR you cannot compare, in the 
same viewfinder and at the same time, more than one 
focal length.  Also, you must have a lens attached
with an SLR - that is not necessary with the Leica,
so you can place a lensless camera to your eye, move
the frame selector lever, and decide which lens is
best for your vision of the scene, and then mount
the appropriate lens.

I'm not suggesting that the rangefinder method is
"better" than an SLR, just trying to help you, and
others interested in this, what the differences are.

The one I bought about a year ago had the number 5359***, and
one that was about a year older, based upon its original
purchase date, is numbered 5351***  I have one numbered
532 and that has the older shutter.  However, some older
bodies were retrofitted with the new shutter box, and, it
seems, that the serial number on the base plate is not always
sequential to production.  Nonetheless, you'll do well to look
for numbers above 5355*** to be sure you're getting the latest
model.

I was astonished when I got my first Leica - an M3. 
Side-by-side with a Spotmatic one could see a remarkable
number of similarities in design, size, weight, and
ergonomics. Apart from the pentaprism, both cameras are about
the same height, the Spotmatic is just a scosh wider, and the
depth of their bodies are just about identical, with the
exception of the protruding area where the Pentax lens mount
is.  They both have their edges rounded to one degree or
another, allowing for a comfortable grip.  What this means is
that they feel quite similar when being held in shooting
position.  Weigh each body without their lenses.  The Leica
actually feels a little heavier.  Specs I've seen put the M3
at 595 grams, the Pentaxes just before the Spotmatic at about
575 grams, and the Spotmatic at about 600 grams.  Add a 50mm
lens of their time, and their balance is very similar, too.

These two cameras have much in common considering that they
sprang from two entirely different cultures and are of
different designs.  IOW, both Pentax and Leica got the basic
design - the ergonomics - right.  Both feel very comfortable
in the hand, both have controls that are easy to use and feel
properly located for most people, and both are respected and
sometimes even coveted forty and fifty years later. Both the
Leica M2/3/4 and the early Pentaxes were built conservatively,
with thought towards simplicity, durability, and longevity. 
Both are, IMO, examples of elegant design.

Thanks for all the comments, Shel, especially about the noise level. It
would be worth it to me to seek out a later camera. Anyone know yet what the
serial number range of LX's ended up being?

As for the above, I've always thought that Pentaxes are the SLR equivalent
of Leicas. Actually I held that opinion about the Spotmatics (their
Achilles-heel metering aside) , because the later cameras (with the possible
exception of the MX), nice though they are, don't quite live up to the
description. But the LX does.

Boy, would this ever get me in trouble over on the Leica list. Please,

Another wonderful feature is that the different frame lines
can be brought into view just by moving the frame selector
lever on the front of the camera.  One needn't change lenses
in order to see which lens will provide the optimal
perspective, or cropping, of the subject.  This will work for
lenses of 28mm, 35mm, 50mm, 75mm, 90mm, and 135mm, depending
on viewfinder and camera specs.  In fact, one doesn't even
need a lens on the camera to get this to work.  It's a nice
feature ... perhaps an even more valuable feature than DOF
preview in some cases.  OTOH, I do like DOF preview on SLR
cameras, and I use it often.

I really think the LX and the Leica complement each other very
well.  The MX and Leica are also quite nice together.

Re: What's all the fuss about the DOF Preview

2001-07-07 Thread Shel Belinkoff

Hi Mike ...

I read the Gibson interview just a day or so back, so I
suppose his comment was in the forefront of my mind, although
I have heard others express the same thought in a very similar
manner. I really didn't think much about their origin when I
typed those words.

As for the LX noise, it varies from camera to camera, and, it
seems, depends a lot on which lens is attached.  I have three
LX, and the older one makes that "sproing" sound in just about
every instance.  However, I have two newer models, one of
which I recently purchased new myself, and their sound is more
like a quiet "thunk".  However, when I placed a K24/2.8 on the
newest body, the shutter sounded like the older camera. I was
very upset, thinking that I'd damaged the body somehow.  But
when I changed to another lens the camera went back to making
the quieter, more substantial sound of the new body.

I've also heard some list members note that the sound changed
after a CLA.  So, while you are correct in terms of what you
hear with your LX and with whatever lens(es) you're using,
it's not true of all LX under all circumstances.  This of
course in no way diminishes the fact that, in all cases, the
LX is louder than a Leica.

Hi Frank ...

I think the best feature about true rangefinder cameras is the
viewfinder.  With the Leica, as with others, one is able to
see outside the frame lines, and can watch the scene and the
action unfold in front of you.  One makes a photograph based
on the presence or absence of various aspects of the subject,
and is able to anticipate a photographic "decisive moment" by
what's taking place outside the frame line.  With a reflex,
the camera tells you what it sees.

Having used a Leica quite a bit lately, I can tell you that
going back to an SLR is like looking through a tunnel or a
small tube - the view is quite restricted by comparison.  If
one likes to photograph people or scenes in which there is
some action, the rangefinder offers, IMO, a much better
viewfinder, especially with lenses in the 28mm - 90mm range.  

Of course, the rangefinder is much quieter, and more
unobtrusive. A Leica, for example, will get you photos that
just wouldn't be possible with an SLR.  The MX and ME Super,
for example, are actually smaller than the Leica, and weigh
less, too, yet their noisy shutter, and (mostly) larger
lenses, make for a less stealthful and more annoying camera in
many instances.  One exposure with an SLR in a quiet room
alerts everyone to the fact that someone's taking pictures.

It has been demonstrated time after time that people are less
concerned about being photographed with a Leica than with an
SLR.  Perhaps it's because the camera has an old-fashioned and
non-professional look to it, or because the lenses are smaller
and don't pose quite the threat, or because the camera is
quieter ... it doesn't matter, people accept being
photographed with a rangefinder more easily than with an SLR.
I suggest seeing the movie "Pecker" to see an example of
this, albeit a somewhat exaggerated example. 

For the techno-enabled the Leica is a poor choice.  There's no
auto exposure, auto rewind, data imprinting, matrix or
multi-segment metering (heck, only the most recent even have
meters, and they're quite rudimentary), no custom functions,
etc.  It's only the photographer and the camera, with the
photographer calling all the shots.  The camera never
interferes with your intentions, but, unlike many wunder-SLRs,
one must develop more of a relationship with the Leica in
order to get the best results.

In many ways the Leica is much slower to operate.  Film
loading and rewind are slower, and slower yet with earlier 
models, yet, once loaded and in shooting mode, the camera 
is amazingly fast to use.

Of course I'd never give up my LX cameras.  They make a great
combination with the Leica.

Hi,

there's nothing very complex or difficult about the depth-of-field
calculations. It's a very simple matter to type a few formulas into a
spreadsheet, even one on a PDA. I put some into a spreadsheet and put
it on my website some time ago:

You're welcome to download it if you want. I got the formulas from
"The professional guide to photo data" by Richard Platt. Everyone should

Personally I find it easier to use the scale on the lens.

Right - as you, I use a rather "crippled" combo of SuperProgram
w/ m42 Takumars via the K-adapter for 95% of my photographing. I
am effectively in "Permamnent DOF Preview Mode" since exposure
must be made "at aperture". However, after having used the old
6x6 folder and then a few Canonets for earlier years in my latest
round of "interest photographic", I just got my first SLR's a mere
5 or so years ago. By then I had become aware enough of DOF effects
that I rarely relied on the mechanical preview - rather just the 
scales on the Takumars. Much easier than the charts I carried around
w/ the non-SLR cameras. I like that my 6x9 Bessa II has a DOF scale
incorporated into the focusing knob (no need for charts :^)

You're right that doing it "by the numbers" is a good exercise, and good to know
