I checked this out with a local dealer, and you're right.  The N8008
*can* drive the AF-D lenses.  In addition, he noted that the plain AF
lenses are no longer available.  However, there *are* motors in the
AF-D lenses.  So Nikon N8008 owners now get to pay for the motors in
the lenses like all we Canon owners...  AND NOT GET TO USE THEM!

In addition, the whole argument that the N8008 boosters have been
using is that "Nikon is a more professional camera".  Well, how
professional is a camera that does not get support in focal lengths
above 300 mm?  And face it, even driving the 80-200/2.8 IF ED is a
real challenge for the N8008s.

Well, I don't know when the F3AF and Penteax MEF came out relative to the
T80, but I can't imagine they were out much sooner.  Though the T80 was
a disaster, Canon managed to get it right in the end.

Whatever happened to the disc cameras that kodak first introduced a few
years ago.  I don't see them being sold anymore.  I had one of their first
models and the picture quality wasn't that good. But, I was thinking a 
few years more, they would have improved it, maybe a 35mm disc with autofocus.
But it looks like they didn't. What happened?

I use a remote contact with my 8008s and 8008.  Specifically, I employ
the threaded-barrel connection on the front of the camera body.  nikon
sells remote cords that mate with this.  You can also buy aftermarket
connectors that essentially convert your cable release to a switch actuator.

You might try what I have been using for a year or so with reasonable
success. Get a plastic dishpan as a water bath. Buy one of those
six-buck 200 watt immersion heaters that are meant to boil one cup of
water for tea. Wire it in series with a six-buck dimmer switch. By
trial and error find the setting of the dimmer switch that will hold
the temperature of your water bath. Don't try to heat the bath from
scratch with this device. One warning: don't give it full power when
not immersed. It can get red hot in seconds.

Subject: Vignetting with Canon EF 28-105mm USM
Date: 29 Dec 92 16:20:01 GMT
Organization: Spider Systems Limited, Edinburgh, UK.


About a week ago someone posted something here saying he had experienced
vignetting at 28mm with the Canon 28-105mm USM lens.  I own one of these
lenses, so this was interesting to me.  I had never noticed the effect,
but I marked the post as unread so I could look into it and respond later.
Unfortunately, my friendly neighborhood news system deleted it anyway.  So,
this post is a followup to the previous post, and I hope the original
poster sees it.

Anyway, I have owned this lens since the end of October, and I have probably
shot a dozen rolls of prints with it.  I looked at my negatives, scrutinizing
those I thought had been taken at 28mm, and I could see no vignetting.  All
I can think is perhaps you were seeing the effects of either an improper
hood, or a large filter.  I use a Hoya UV filter over mine, and still have
not had any problem.

By all counts, the lenses in Canon EF lineup are excellent, even the cheap
plastic Rebel/1000 lenses.  Given that the 28-105mm USM costs about 40% more
than the 28-80mm USM, and that Canon is selling it along with their next-to-
top-of-the-line EOS-A2/5, I would hesitate to suggest the lens itself has
such a fundamental flaw in its design.

Reply-To: research@oasys.dt.navy.mil (Mike Leavitt)
Distribution: na

I'm a new reader of rec.photo, inspired by a need to upgrade from my 20-year
old Canon FTb.  I have several questions.  If they're FAQs, please respond
directly, since I haven't been able to get at moink.nmsu.edu to see what
they've got.

First, I'm leaning to the A2 rather than the 7xi for a couple of reasons.  The
A2 has built-in most of what I would have bought cards for the 7xi; the
five-position "smart" focus gadget looks very neat; it has a better rep. for
construction solidity; it has a better design for information exchange between
camera and lens; it looks like it should be a better low-light performer given
the wide diameter of the lens mount area (or whatever you call it!).  

On the other hand, the A2 does not have a power zoom/
autozoom capability.  Question for autozoomers:  is it very important to have
that gadget?  If the camera can do everything else, can't I zoom it myself?  
Question for everyone else with experience with either, am I omitting any
crucial differences that will be show stoppers?  (I intend to do mostly
outdoors/nature work.)

Second, the old mail-order vs dealer question.  Since I'm a new reentrant to
this area, I'm a little nervous buying mail order (I buy most of my computer
stuff mail order with no hesitation).  The price difference looks to be in
the $150-$300 range for body and one good zoom lens.  I found a local dealer
who seems serious about post sales service.  Any comments on my dilemma?

[question and elaboration deleted]

With complicated AF systems, it is hard ot be 100% sure when buying
used stuff.  If there is a problem, it is not as easy to service it
at local centers.

I first recommed a complete check of all functions as described in the
users manual.  I also recommed shooting a test roll, with some flash
pictures, on slide film.  Reason is that slide film if properly developed
gives an accurate indication of how the exposure is being metered.
(Printing from negatives always involves adjustments and can mislead
you about camera performance.)  ONe way to check flash sync is to fire
the camera/flash with back open - you should be able to see the flash
illumination at up to the rated sync speed.

The resulting test pictures should have good sharpness.  The viewfinder
image can be misleading; it may appear focussed in the finder, but be
out on the print or slide.  Such would indicate problems with the focus
system or physical distortion of the camera body.

I also recommend at thorough check in you local shops.  I personally
do not have a high opinion of the photo/camera fairs.  Often their good
deals are actually higher than local shops.  After the show is over,
you have no recourse if there is a problem with the equipment.  If you
buy used equipment from an established local store, you have a place
to go if the stuff turns out to be bad.

I have found the camera fairs to be an interesting way to spend a morning.
They are also great sources for hard-to-find accessories and discontinued
items.  If you were searching for a Nikon F1 (old, reliable manual body)
and the earlier series of lenses, then the fair would be a good source.

From Materials and Processes of Photography by Stroebel, Compton, Zakia, Current

            D = SQROT v / 141  where D = pinhole diameter in inches
                                     v = pinhole to film distance in inches


From Ilford Manual of Photography

            D = SQROT v / 125  units same as in M&P book


From Handbook of Photography by Henney and Dudley (1939)

To have focused, your subject must have been in the middle of the
viewfinder.  So, it makes sense to take the exposure off the middle of
your viewfinder because the subject is there.

Am I missing something?

This is one reason why I can't see how the 5-segment OTF metering of
the N90 can be much better than centre weighted.  The segmetation
pattern looks good for centred subjects, but by the time you're
exposing the film, you've recomposed...

Is it just a guess or have you actually tested any of the TS-E lenses? A

24/2.8 at any aperture. I'd like to hear any first hand experiences though.
