Before you went to flame at this guy, Rick, you should have made sure
not to make the same mistake about Minolta as he did about Nikon.  You
don't have to replace anything if you want to use the xi series
cameras. All extras that xi lenses have is power zoom which is
necesary for auto zoom and they tell the camera what the current focal
length is.  None of these are a great reason to buy an xi lens, so I
use and prefer non xi lenses with my xi camera.

Apparently you've never taken a picture of something you wanted scanned
into a computer, Richard.  This could be the cheapest method yet devised
for entering images into hypertext documents, icons, or what-have-you,
but because Kodak can get patents on this stuff, and because they don't
percieve such a market to be lucrative enough for Great Yellow Father
to address, it will die before it is ever born.  A classic example of
why such patents are more than just evil, they are stupid and counter-
productive.

Even if you know only in F ---> -40C=-40F.
Wind is also an important factor here, because YOU have to take a photo. It

Here's a data point on Camera World of Oregon to be included in the
charts of "problems with mail order companies".

I've been ordering from CWO for more than 3 years and never had a
problem. Last time they backordered a filter. Two months and half
later, no filter (but credit card charged). I called to cancel the
order and learned that it could not be done through the 800 number.
Ok, I called the regular number and they took 5 minutes to finally
track down my invoice and cancel the order. In the same 800 call, I
decided to order a binocular. Ad price: $80; guy on the phone:
sorry, but the manufacturer increased prices, and now it's $95. I
declined, called Adorama and got the same item for $75.

That's the story, for what it's worth.

No, f/1.4 is a geometric relationship between the focal length and the
lens opening. To account for light losses you use T-stops.

I seem to have missed the beginning of a discussion on T-Max films, but
here's my 2 cents worth:

I, too, think the films are touchy, but in my opinion the results are
worth the extra care. The major problem I had is with agitation. I get
'surge marks' on the first few frames when I use stainless steel reels.
I switched to Paterson tanks and reels, and that solved the problem. I
use 5 inversions on the minute and 5 'twists' on the half minute. Next,
I always pre-soak in plain water for one minute (timed) before
developing. Needless to say, I have to be very careful with temperatures

The problem is where you buy UV transmitting lenses.  They exist as a rare subspieces of "glass" at prices guaranteed to astound.  Call Hasselblad for some scary numbers.  There used to be some demonstration photographs in their catalogs.  NASA has long been a regular customer.  There may also be some special film emulsions, all the examples I have seen were B&W, and I believe were 
taken on standard films.  Remember that X-ray films, and even conventional emulsions, pick up high energy electromagnetic radiation easily once in the optical path, so the main problem is getting around the low transmission characteristics of glass to UV. Then there are the problems of how to get rid of the unwanted optical wavelengths.

[ Lots of good stuff deleted... ]

you can use a lump of Stainless steel as a cathode, and remove the plated out
silver quite easily.

For small olumes, LOW current electro cell recovery would allow re-cyceling of
the Fixer, and a good saving from not buying new fixer, and stop the impact
on the drains...

Any-one have the voltage/current etc for this? Prferably for rapid ( NH3 )

I think that color films, or at least Fuji color films, will go down below
400nm. Looking at the spectral sensitivity curves they are certainly falling
at 390nm (which is the limit of the published data), but even so the
sensitivity at 390 is greater than at 500nm or 600nm (crossover points between
the blue-green and green-red sensitive layers). I wouldn't be suprised if there
was some attempt to include a UV blocking layer though. It would seem to make
sense to limit UV sensitivity if possible for consumer type films.

I don't think anyone has mentioned the 80-200/2.8L!  If you really want
85, 105, and 135 there's a lens that can do them all.  It's nice and
wide, but more importantly it's supposed to be quite contrasty and sharp.
Definitely the lens I'd go with!

to get the SC-17 extension cord to really hvae fun (AF is actually
useful because you hold the flash off camera with one hand and focus
and shoot with the other).

The 80-200/2.8 is great but don't expect to ever use AF with it.
Unlike at least one off-brand 80-200, the focusing isn't internal so
the camera is trying to rotate a Honda-size weight.  Of the wide
angles, I've had the most fun with the 20/2.8.  I also love my 60
macro.
