 It only really becomes an investment if the product is discontinued
while there is sufficient demand for it.  Examples:  4+ years ago I
bought a new Fujica 645 folder for $380, and I now see used ones going
for $700+.  Used Olympus XAs were going for twice what they cost new
while still a current product.  I bought a black Nikon FE2 new for $250
in '85, now a black in mint condition sells in Shutterbug for $400-450!

So if your Hasselblads or Olympi are discontinued, you will have an investment
on your hands, and start to wonder whether the cost of its utility is outweighed
by its collector's value.  Who wants to slam around an expensive collector's item
that is somehow more valuable gathering dust on a shelf?

I concur, but a number of fashion photographers in the Miami Beach area
prefer Kodachrome.  Maybe it's just to please the magazine editors.

When you use Tech Pan and Technidol, basically what happens is that
the film grain and resolving power no longer have any effect on the
quality of your photograph.  It's as if those limitations go away.

Then other limitations come into play.  For the first time you'll find
you need a tripod even at 1/100 second, because you can't tolerate the
slight blurring that used to seem acceptable.

And you must focus _very_ carefully, and use a good sharp lens...

	My guess is that using 49mm, as opposed to 52mm and larger lens
	diamters, makes it harder to gather light in the fast end, and hence
	would contribute to an f/2 lens being built rather than an f/1.4 lens.

Well, I don't know much about the 70-210/2.8, and I don't know anything
about the Canon EOS, but I do know that I'm quite happy with my Sigma
75-200/2.8-3.5 for my Minolta Maxxum 7000.  Good, crisp details, multi-

sheild on it.  Don't know if that helps, but I like it.

every1 seems loving thoses high speed high dollars lens
such as 300mmF2.8 or 200mmF1.8 lens.....but not many
people can afford it or willing to pay the big bucks for
it.
For me, i'm thinking this way:

I can get a 300mmF4 or 200mmF2.8 for roughly 400$ (used but
in perfect condition).

with such advancement in today's color films, 200ASA does
have VERY good resolution (almost that of 100 ASA films)
so if it's true that a 200 ASA gives an additional stop over
100 ASA, and if i'm using 200 ASA instead of 100 ASA with
thoses 300mmF4 or 200mmF2.8, HEY, 
I just got a 300mmF2.8 or 200mmF1.8 !!!!! for not mucho money :-)

That's a simple solution for thoses 300mmF2.8 fanatics who can't
afford it and U give up only a minimal loss in resolution but well
not every picture will be blown up to 11 X 14 or more :-) so 
200 ASA is not that bad...

Well, I'm one RB user who DOES lug his RB67 plus 2 lenses and filters and
tripod through the mountains.  Not something one does casually, but it's
"do"able.  I like the format, the interchangeable backs and when it's windy
(fairly common up high), the weight isn't such a bad thing.  You can trigger
the lens shutter after you trip the mirror for real long exposures.  Finally,
they're built like the proverbial brick outhouse.  Given I was going for the
most image size I could get in a med fmt slr, I like the 6x7.  Bronica makes a
smaller and lighter 6x7 without the rotating back.  I personally like the RB's
back.  A drawback with the RZ is that it's dependent on it's batteries.  In the
cold they suggest you use a remote pack you keep under your coat.

They don't have their rep for nothing, but even their used stuff is pricey.  I
was able to get into my RB system for 2/3rd's what it would of cost me for
Hassie used.  And when you're up in that price range, that means you get an
extra lens or few backs for the same money.  Ansel Adams loved the Hassie
optics and the square format, but I guess I'm a more rectangle kind of guy.

Other potentially interesting features:

I asked for a a price just across the border in germany, i think
the price in the local foto-shop there was about DM 450 or DM 500
(i'm not sure, i had the price written down but not at hand.)
I think that was the price for just the flash itself, there will be
additional money involved with the adaptor. The folder announces
'package deals' of both flash and adaptor.

I did not yet do a 'price/bargain hunt'.. i will try to find out
more. Anyways, i wouldn't be surprised if the european prices
would be somewhat higher than the american ones....

According to the folder the Nikon, Minolta and Canon adaptors were available,
and the Pentax adaptor was announced. I don't know (yet) if the Pentax
adaptor is available already. (and the pentax adaptor is most interesting
for me (as Z1 owner))

Actually, it uses a new SCA-3000 system to support the new features.
The SCA-300 adaptors can be used, but then not all new features are available.

Could you (or someone else) elaborate a bit about the funky features of
the SB-25? I know litle about it, and it would be interesting to compare...

Wrt camera-specificic funky features: from the folder i got the impression
that the _adaptors_ do have some knobs for camera-specific features
(eg. TTL flash exp. compensation for Nikon, front-rear curtain sync selection)

		Hello; I asked in November 1992 about a Crown Graphic [4x5]
	I've inherited two solid 4"x5" view cameras from a great-uncle; I had
been looking in pawn shops etc for 4x5 cameras then after several months I
remembered these mysterious relics.
	Thanks for the cogent advice !  I enjoyed shopping around while educated
of the equipment.
	But so far I have spent just $22 and that for film.  [This week I'll get
that first exposure finished.]

			The hardware that I've exhumed :
		"Graflex D" [Graflex' "Speed Graphic" plus a viewing hood;
~1950; no questions]

		"Premo Pony" [made between 1910 and 1920]
	The piston lens allows f/8 to f/64 [and accurately 1 second to 100th and
maybe 200th second].

		I have questions [to those reading this in January 1993] :
	1] For what bellows length [or it equivalent, object distance] are the
Premo f-stops valid?  For close-ups with extended bellows I intend to open
further but from what standard -- perhaps the focus scale below the bellows?

	2] Will a piston lens snap any faster than its top setting?  Past 100th
second the tension knob continues a bit before reaching the Bulb and Timer
settings; I figured that it might reach 200th second.

	3] In covering three visible bellows holes [on corners] should I avoid
duct tape?  I plan to use black, fibrous duct tape.  *Your method* is welcome. 
Local shops would only replace my bellows.

Most small silicon solar cells should work. Most small audio transformers with
a resistance of about 8 and 1-400 ohms should work. The SCR could be something
equivalent but it should be able to handle 200 or preferably 400 volts between
its A and C leads. Since a SCR is used the flash needs to connected to it the
right way, meaning the SCR's output is polarized and it needs to match the input
to the flash. If the flash does not fire with the connections wired one way try
reversing them.

If you like Kodachrome, use Kodachrome 25.  You'll need a tripod anyway,
probably, and K25 has much kinder reciprocity characteristics -- with long
exposures (1/10 of a second or more), K64 goes greenish but K25 doesn't.

This is in fact a good possibility, dumb as it may sound.  I've got some
information that came with a Tiffen catalog I got a few years ago, and
among other things (on how they make their filters) it says:

     "The TIFFEN View On Multi-coated Filters
      ---------------------------------------

   After extensive research, Tiffen has found no significant advantage to
multi-coated filters.  Tiffen has determined:
   o  Multi-coated filters have no significant effect on picture taking.
   o  Multi-coated filters, when used with multi-coated lenses, may change
      the spectral values of your lens and alter color response of your film.
   o  Multi-coated filters are very difficult to clean, often damaging their
      coatings when pressure is used to clean them.
   o  Multi-coated filters are priced higher than uncoated filters.
   o  Multi-coated filters are not really multi-coated, they are only two
      layers coated to a visual color and not to a spectral curve.

   In view of the above information, Tiffen has chosen not to manufacture
multi-coated filters."



Personally, I do use multi-coated filters whenever I can.  I think my only
Tiffen filter is an FLD, because theirs works better for me than the
others I tried.

I'm the guy who posted the article. You must be more than lucky with your lens
because 2 friends of mine have the same lens and the same vignetting problem
at 28mm without any filter or hood, and "Chasseur d'Images" also mention it. 
However it's *not* a big vignetting, I'd say 0.5EV maximum (well it can hurt 
with slides :)

Also, if you put the Cokin filter holder, the vignetting is more than obvious at28mm (black corners).

Bottom line, I can deal with that and I still like this lens!

Happy? ;-)
