Well, I luckily caught my view camera when it was blown over; the cost of
that lesson was just a good adrenalin rush... ;-)

Anyhow, I always thought I'd never drop a camera; that only happens to other
careless people (ha!). Experience has taught me otherwise. Accidents happen
to everyone, and their likelihood is proportional to the expense of the 
equipment involved... 

For instance, there was the time that I had my 800mm Nikkor T on my Horseman
camera and it was pointed up at about a 60 degree angle. This is a
front-heavy combination, due to the weight of the lens and the fact that I
had the rear tripod standard set to the rear of the camera (I was preparing 
a second tripod for the front of the camera). All of the sudden, the friction 
lock on the junky Bogen tripod head just gave out (a phenomena I have
witnessed several times since with Bogen heads), and the camera swung 
downwards. The front of the monorail hit a tripod leg and put a 1/8" deep 
dent in it. I was certain the lensboard was going to fly off or the at 
least the front standard was going to swing forward and let the lens crash 
into the monorail. Thanks to the VERY sturdy construction of the camera 
and VERY positive locking mechanisms, none of this happened. The camera 
and lens were unscathed, the ding in the tripod leg cosmetic. Think what 
would have happened to a wood camera (though the real lesson is don't 
overload your tripod head)!

Also, there was the time my folded-up Linhoff Technikarden dropped three
feet onto asphalt when I opened the back door of my car. It was in a Zone 
VI field camera bag, which offers *zero* mechanical protection when dropped 
on its side (and that's how the bag landed). One corner of the rear standard 
was flattened about 1/16" of an inch; this was the first contact point 
with the pavement and made a hole in the bag's naugahyde. The camera was 
otherwise unscathed and works perfectly (I've since replaced the Zone VI bag
with one made with high-density foam and that won't slide around on a car
seat, AND I open car doors slooowly and carefully now!) Anyhow - if it 
had been a wood camera in the bag, it would have been busta-mundo. 

So, while I think that wood cameras are beautiful, in my book, metal 
cameras are much more practical!

Reply-To: chaloux@mandolin.mitre.org (Dave Chaloux)

I have been getting into Astrophotography lately and have been using a
Pentax K1000 for same. I have thought about replacing this camera and getting
something that:
1) I can use for Astrophotography.
2) I can use for Auto Everything.

When I went to the store and started looking at cameras I noticed the
following.

1) Many of the cameras do not have cable release.
2) Many of the cameras drain the batteries even in Bulb mode or T mode or
whatever the manufacturer likes to call it.
3) As far as I can tell, many still do not have mirror lock up which is
part of the incentive to use something other than my K1000 for
Astrophotography. Brighter focusing screens are another.

Can anybody recommend a good autoeverything camera that still has
cable release and mirror lockup and that preferably doesn't drain the
batteries and short of that takes NICADS.

Looking at the 8008 it looked like it had some sort of remote unit that
might serve the function of a cable release. Is that correct? Looking at
the instruction book, I could neither verify or reject that. Also, does
it have mirror lock-up? I saw nothing about it in the book.

Also, I have noticed the shutter on my K1000 gets very cranky when I am out
in 20 degree weather. Is there something I can, should, etc. lubricate to
help it out in this regards?

Thanks.

On a somewhat related note, what should I expect to spend for a good
color enlarger?

Finally, I have heard mention of a FAQ for the newsgroup but still haven't
seen it. Does this exist? Thanks.

That's a good question.  Ray McSavaney related the story about John Sexton
as if it was new news but I didn't think to ask him when it happened.  Does
anyone have any recent information?

Linda Conner prints on POP, and I asked her where she got her paper.  Unfor-
tunately, I can't remember the answer, but there is a manufacturer.  Perhaps
it is the Chicago reference mentioned in another posting.  Her prints are 
very rich and warm; it is certainly worth following the trail and finding 
the source if this interests you.

Simple question, but no simple answer! microwatts/sq.cm is a radiometric 
unit, whereas footcandles (= lumens/sq.ft) is a photometric unit.
Radiometric units are fundemental and cover the whole spectrum while
photometric units are based on the response of a "standard" human eye.
To convert from one to the other you need to know the spectral irradience
as a function of wavelength for the source of the light measured in
microwatts/sq.cm. You then have to integrate this function across the
"standard eye" response curve from 380 to 770nm.

What this boils down to is that, for example two sources of different
color temperature (say a lightbulb and a flash) may give the same reading
of microwatts/sq.cm, but they will have different values for footcandles.
The source with the greater amount of power in the 380 to 770nm part of
the spectrum (biased towards the peak response of the eye at 555nm) will
have the greater footcandle reading.

Just got one last week.  I thought the color and sharpness was good for a 
lens of that range, but AF with my Nikon F4s is terrible.  Mind you,
F4s is perhaps the best and even the most expansive AF 35mm production
today, but it takes a long time to do AF with the Sigma lens.  Of course
the primary problem is the 5.6 aperture (Nikon stated it requires 4.0 or
faster), but I thought it should be work maybe 90% of the time.  It was more
like 10% or 20%.  

Even with manual focus, the standard split-field focusing screen often
black out on one half, but you can usually get it to work with a little
eye level adjustment.

If you get it for manual focus, fine.  But I would not recommend for AF.

Hi everybody,
this *may* be a FAQ, but I'm going to ask it anyway :)
Are unexposed/exposed films affected by the X-rays they
use at airports to scan luggage etc.?
I know of "film safety bags" that are used in order to
protect films from the effect of some sort of rays.
What I don't know is whether they contain some kind
of lead in order to provide a shielding against those rays.
I also heard that only films of > 400 ASA are sensible
against those rays.
Any comments? Please answer by e-mail, I'll summarize.

	Yikes...I wouldn't call the Elan "low end". I think it was said
best by whoever noted that the 10S and Elan are complement cameras since
the Elan incorporates a few new Canon EOS features brought out since the
10S.

I've observed that most people who post complaints about mail-order compamies
are saying that they didn't get some order when it was promised and had to
leave on some trip or something without the product.  I've not been burned
yet by mail-order companies (I even once had success with Cambridge a long
time ago!), but I didn't bother trying to order a Bogen tripod last summer
when I realized I needed it just two weeks before I was to go on a trip, even
though my usual place (Adorama) gets things to me in 2 weeks on a regular
basis.  I'm suspect that one of the reasons that I like mail-ordering
is that I'm usually lucky enough that the time I have the money to buy
something never coincides with when I go on a vacation (1/2 :-().

I think it's a good rule-of-thumb that if you need it in anything less than
a month, then don't order it by mail.  Of course, sometimes you can't get it
locally, and then I guess you have to throw yourself on the mercy of the New
Yorkers.  As Mike pointed out, you can't believe what the sales-critters
claim about shipping dates, apparently no matter what you pay to have it
shipped.  I wonder; should such a warning be added to Mr. Blondin's survey
(sorry if I spelled the name wrong!)?
