I own Nikon Action Touch (A/T) and Yashica T3 (T3).

A/T:
According to the Nikon specs, A/T is waterproof down to 10m (30f). In six years
I have been using it, A/T never failed while submerged to ~20m in Atlantic,
Pacific, Read Sea and Dead (solty like hell) Sea. It withstood saunas and
russian steam baths. The thing IS rugged.
Contras: Lens has substantial off-center distortions. Limited shutter
speed range. No exposure compensation.

T3:
Very good for P/S lens [my other camera is Leica M 8-)].
Wide shutter speed range: 1" to 1/750".
Exposure compensation.
Good for rain and snow.
Contras: Weak construction  - one 4 ft drop of a cased camera resulted in
the cracked flash lens and popped LSD display cover.

Keep in mind that a disc copy will in some cases "tie up" the machine 
even longer than a simple transfer.  The CD readers/writers are the slowest
part of the system.  The scanner can make a 2kx3kx24bit scan in about 6 
seconds, whereas a 150kbyte/sec reader and a 300kbyte/sec writer are 
limiting factors.
The lab may also turn a larger "margin" on the conventional film processing.

I have been using only B&W film in my 4X5 camera and now with the
fall season upon us here in the East, I thought I'd take some slides
of the fall colors. 

I have a box of Ektachrome 64 and the thing that I'd like to know is
how do you rate this film. Is it like Kodachrome 64 where you rate it
at 80ASA or do you rate it at 64 like the box says, or maybe something
entirely different. 

I would appreciate any advice from someone who has used this particular
film in 4X5 size, and I thank you in advance.

I agree. He had an artist's approach to the process, and not a
technician's.  Or, he chose to make it a little difficult to follow.
Either way, he was pretty vague.

I got some nice metallic golds, reds, browns, blacks, combined with
artifacts of the equipment I was using (pyrex trays and canning jars).
At least the concentrations for the solutions were apparent from the
articles (I believe there was an Amateur Scientist article on the same
topic in the same issue.

I designed an experiment, that gave me a cross section of some of the
possibilities of the process. One, two and three ingredient sequences,
with varying times between the ingredients. With a little effort, you
can design the experiment to take place on a couple of sheets of
paper, divided into quadrants. From that, I made my compositions, and
then experimented semirandomly. 

This seemed to work pretty well. You can see the colors as they are
generated, so the feedback is fast.

Interesting. I would like to experiment a little with combining
conventional paper exposure with this stuff, to produce washes ofw
color. The amount of light required for the chromoskedaisic (was it
really spelled chromoskedesik?) would seem to rule this out, though.

I think the photoswap idea is great.  Often it is hard to tell exactly

Sometimes I get the impression that not only Nikon, Canon, and
Minolta users are reading rec.photo ;-); from time to time even
some Pentax addicts show up. For all of these who are interested
in the new lenses announced during the Photokina, here are the
technical data from the data sheet I got at the exhibition:

                      FA* 1.4/85 (IF)        FA* 2.8/200 ED(IF)
Elements/groups         8/7                    9/8
Smallest aperture       22                     32
Cl. focusing dist.      .85m                   1.2m
Diameter/length (mm)    79x70                  82.5x134
Weight                  550g                   785g
Filter thread           67mm                   77mm

Both are new designs and don't have much in common with the previous
85/1.4 and 200/2.8. They have quite a solid "look and feel" (at a
first glance) and have a real focusing ring (!) that can be engaged
by sliding it forward (similar to the one on the 24/2.0).

What I didn't particularly like was the shiny cream surface and the
unnecessarily large and pretentious lens shades that can be bayonet
mounted to the front of the lens.

BTW, the Pentax rep who I was talking to admitted that Pentax had
neglected the 35mm SLR market for some years, but they would try to
win back some of the serious amateurs. Although, he said, the market
presently wasn't profitable for *any* big manufacturer (apart from
Leica, perhaps). 

Would you believe that??  I had always thought that at least Nikon
and Canon were making profits...

     I am interested in anyone's opinions of Sigma manual focus lenses, 
specifically:

75-200 f/3.8 Ultra Compact
70-210 f/4 Macro

Are apochromatic lenses REALLY worth the added expense? From what I've gathered,the APO lenses of the same focal/fstops are roughly 50% more expensive.

I'm interested mostly in direct experience opinions of Sigma lenses, but 
general comments on Sigma and "I've heard this..." type comments are also 
appreciated.

Not to sound pushy, but there's a time constraint here, so quick replies will
be appreciated dearly.

I thank all of you for helping me with various other q's (and this one, too,
of course!)

Over the years I have found that I can alter the character iof the slide films
I use by sligh variations in exposure, or by placing the neutral "grey"
zone in different relative contrast areas.  Slightly over exposed
RDP (1/3 stop or even a bit less) becomes a bit de-saturated, and the
color response is thus quieter..on the other hand slight underexposure
deepens the colors..but you have to be slight!

I have read a lot about how poeple rate their Velvia..quite a few shoot it
at 40 rather than 50.  I have found that it is not so much a balnket theingas
how you choose the placement of the neutral zone in each photograph.

It is a highly saturated filom, and does NOT need any polarization on
a clear blue sky day...and sometimes if you shoot it at 64 (well, meter at
50 and open 1/3 stop) you can make that intense blue a bit less so.

The point is that with chromes you have tyo do your compensations in the
camera as opposed to print film where the darkroom is the final arbitrator
of exposure value and color saturation and density..this cals for more
exacting evaluation of the subject and makes one a more attentive shooter..
at least that's the theory!

I agree, it's a pretty good mag (I've been getting it since 1979)!

It's one of the few magazines around anymore that devotes significant
space to showing individual photographer's work - and not just an "eye 
bite" (like a "sound bite"), but enough so one can really get an idea 
what the photographer is doing.

And they do tend to review an interesting mix of cameras.

I have not received my free copy either. (6006, March 92).
They promised a free copy of Nikon World for responding to their questionnaire.

It seems that Nikon wants to get customer info for free and we should

I have no personal experience with 110, but keep in mind that required
film flatness is a function of aperture and ultimate degree of

with 4x5 and drops off to practically nothing with 110.  The formula

If you are interested in Stieglitz and art, I would like to recommend
you to see paintings from his wife Georgia O'Keeffe. Especially her "100
flowers" book of paintings.
I like her very much, it seems that there were an interesting couple.
