Geez, you guys, you don't seem to get the point. Yes, of course it does, but
so do ALL the other lenses. I only chose 8x because it is the largest
enlargement most people ever have made. I could have chosen 11x14's or
16x20's and all the SQFs would have been lower, but the RELATIVE
performance of the lenses would have been exactly the same, i.e the
optical quality of the EF75-300 is certainly comparable (and in some
cases better) than that of the lenses I compared it to.

Has anybody found out from any review , etc. whether the two databack

For Sale:

        Norita 66 SLR     
          Includes Prism finder and 80mm f2.0 lens

        This camera would be a relatively cheap way to get into Medium
Format interchangable lens SLR.  If you're thinking of getting one of the
Kiev's this would be a good alternative.  It's made in Japan and was designed
by the same person who designed the Nikon F.  It's designed like an
oversized 35mm SLR which makes it easy to hand hold.
        This specific example is in GREAT condition.  Shows only slight
brassing in a few spots (E-mail for precise description).

        Also includes original Norita promotional material which describes
everything they ever made for it. (lenses from 40mm to 400mm)

        $500  -   Shipping not included



	Nikon F w/ FTn finder & lens
		FTn meter is active but consistently underexposes by one stop
		F's film counter will reset only if taken past about 5
		esposures (only a problem if you are shooting 4 exposure rolls)
		meter problem defeated by resetting film speed

		Body shows significant brassing
		which is common for black bodied cameras

		lens is 43-86 f3.5 Nikkor zoom (AI) and is in very good shape.

I don't have flourescent light in my darkroom, so I can't comment on the

had significant afterglow.  It was in fact strong enough for me to read in.

After some investigation, I discovered that the light switch only cut one
of the wires, and not both.  Since the lamp also was connected to 
earth/ground, the voltage at the live wire was enough to cause
a significant glow when the lamp was still warm.  
I replaced the switch with one that cut both wires and the glow went away.

My understanding is that the ultra-expensive telephoto and
zoom lenses featuring ED-type elements allows colors in
whatever wavelength to focus on a single plane.  My question
is, if you take a non-ED lens of the same focal length, and
stop it down several stops, would not the inherent depth of
focus at the film plane have much the same effect, esp. with
a subject focussed at infinity?  In other words, would the
ED type lenses really come into their own when used at near
fully open apertures... which kind of implies that the photographer
wanted to either hand hold, or for some other reason wanted to
maximize shutter speed (sports, nature)?  What it comes down to,
for tripod-mounted landscape use, with small apertures, is there
any advantage to ED?

Mamiya are still in business but no longer make 35mm gear (they specialize
in medium-format cameras, and make several good ones).  The Mamiya ZE mount
never caught on and nothing has been made for it for years.

Well I probably shouldn't be doing this...but I do have TWO XA's and I

 The problem with faster exposures is that you often catch the screen in
mid-scan.  a longer exposure limits the visible effects of this 'scan 
aliasing' (for lack of a better term).

Another possibility is a flash exposure (it will probably have to be off
the camera to avoide having the reflection show on the screen). This also
allows you to have people, or other moving objects in the picture.

A simple double-exposure is another excelent option.

The January? issue of Peterson's has an article on all the available 35mm
films.  Along with the specs on the films, they also include the three letter
film code.  I agree that it would be good to have these in the FAQ sorted by
film code.  Perhaps someone already has the list on line.

Hi,
Suppose I hand hold a filter (eg soft focus) in front of a 
lens instead of screwing it on. Now, if my hand holding the
filter happens to shake, will the final image be less sharp
than if I had screwed on the filter? Assume the camera is on
tripod and the filter diameter is much larger than the lens.
Also, does it make a difference if the filter is held very 
close to the lens (small gap ~ 5mm) or at some distance
away from the lens, say 10-15mm ? Thanks in advance.

I had a similar experience in Munich, Germany.  My film didn't seem to
be fogged, but the only fast stuff I had was some Ektachrome P800/1600
which had already been exposed at 1600.  That stuff was grainy (as
expected), but not particularly fogged.  I don't know what the new
system is, but I saw that O'hare Airport, Chicago, USA had the same
"color" x-ray system.  Maybe it's a different freq of radiation, so
that's not the same "x-ray" as the "old" system, and maybe it won't fog
film as quickly.  It seemed to me that the color corresponded to depth
in the bag, or attenuation of signal.  Could be that the x-ray source
and the detector are now in a computer-controlled feedback loop so that
the minimum number of x-rays are used to irradiate your luggage and
film.

All this still begs the question of what are these new security
sensors.  I thought, "CAT scan" refers to using multiple x-rays scans
to cross-section an object, and derive a 3-D image vs. the normal 2-D
"projection" image.  Maybe, we could eliminate what it wasn't. 
Magnetic resonance imaging seems out -- too little time needed, too
many problems with interesting things people but in their luggage, no
signs warning of large magnetic fields, instrument wasn't big enough. 
Ultraviolet, visible, and infrared seem ruled out because to detector
size limitations arising from the opague nature of luggage at these
wavelengths.  Microwaves maybe?

Does somebody out there know the straight dope (beside Cecil Adams)?  I
tend to think that those are just fancier versions of the ol' x-ray
machine.  I suppose somebody could leave a couple sheets of
photographic paper in the machine for say 30 minutes, and see what
happens.  I'm not sure that slightly fogged 35 mm film is particularly
easy to detect unless you have photographed some known subjects, and
can compare film from the same batch.

You can get pages similar to those from the photo labs except that they
are extended to make room for three holes.  Put your negs in such
pages, and put the pages in a archival binder.

Two popular brand names are: PrintFile and VueAll.  VueAll ones are
less expensive, but I I prefer the PrintFile neg/slide pages myself.

As for binders, I quite like the "Portfolio II" from Eraplast Inc. in
Montreal, Quebec, Canada.  Most of the other binders I've seen require
the little tabs to be bent more than 90 degrees.  The Portfolio II has
one big tab that only needs to be depressed about 10 degrees.  Should
hold up better in the long term.

Alas, most archival binders have hinges that rely on the plasticity of
the material (polyethelyne) and may eventually break as most binder
hinges are apt to do.  If you're going to be opening and closing the
binder lots, you might be better off finding an archival box instead.
They're cheaper (less complex), usually made of cardboard (no
plasticity required), and some have binder rings.
