I recently got 2 Canon Digital Rebels (300D, 6M pixels) & a 20D (8 M pixel).
I was using the 300D's in the desert, for astronomy (astrophotography) &
OffRoadRacing.
http://www.jumplive.com/laughlin05/index.htmlhttp://www.jumplive.com/sanfelipe05/index.html
Both climates have dust issues, especially the latter. The 300D "locked up",
because of dust. I had to do the "sensor clean", before I got it running.
Anyone else, have to go to this mode in their exploits in Mother Nature?
A few times, I had the 20D lockup, & I had to power it down (or did I have to
remove the battery all together?)? My Canon T90 (the forefather of the
modern Canon film cameras, then the digital cameras) would ocassionally
lockup ("EEE" error code), & I would have to powerdown to get it normal
again. I guess it's the old "there is no such thing as a perfect computer
program", computer software is gonna have bugs.
Anyone thinking of trading in their 300D's, for the newer version with 8M
pixel (which is also lighter)? I could use the extra pixels, the "lighter"
feature is certainly something a professional photographer can appreciate
since lugging around a lot of cameras & lenses is the No 1 complaint: Weight.
I know the professional Nikon film cameras like the F3 (I have 2 of them),
can go down to some pretty extreme temperatures. They can be used stock in
places like Antarctica. There was a solar eclipse in Antarctica, I think
someone I know used a Canon 10D down there..no problem.

I know that cold weather & moisture can lead to problems with fogging.. The
high-end amateur CCD cameras (for all intents & purposes..they are nearly
professional grade) have built-in moisture-absorbing-rings (the things
cameras get packed with..I forgot what they;re called..oh,
yeah..dessicants). I have the kit which can power the D300 externally: the
"fake battery" module, which has leads for a external power supply. I hacked
this kit, to power it off an old Sony camcorder car-power unit. That's one
way, out of the "cold battery syndrome"..just use an external battery (that's
in a warm-box). That's what I use for astrophotography--because the
exposures are in the several minutes to half-hour (or longer), you couldn't
possibly use a regular battery..it would get exhausted in no time. I use an
18 A-H gel cell (which saved me one day, when my car battery drained itself
in the Arizona desert!). I also have a Honda EU2000 generator (with battery
charging cables), so I sometimes use this for powering the astronomy stuff
(lotsa stuff: laptop, cameras, CCD cameras, etc). I would recommend to
everyone to get a portable gas generator (bring along a 120v battery
charger), for any contingency-conditions. I'm installing 2 additional marine
batteries (in addition to the 1 marine battery & starting battery) in y 4x4
van, since I'm going to be powering all sorts of electronics equipment. I
just got a satellite-DSL thing for my van, so I can download/upload from Baja
or anywhere else. I also have a satellite-phone, if I have to call for
emergency help. I have a Verizon wireless DSL phone-card for my laptop, so I
can access the Internet from practially anywhere ($80/month, unlimited
bandwidth downloads).
Has anyone else, tried to be "Mobile & Hostile"? (mobile Internet setup).
Or is it, pretty much download pictures to laptop or portable hard-drive & go
home to do the stitching?
I recently got some cold-weather gloves, for handling D300 in 30 deg (or
colder weather)..oh those aching fingers!! (i actually lost fingerprints &
feeling in my hands for about a month, since I totally brutalized them in
December cold in Arizona, handling the D300). Some camping guy finally told
me how to do camping right: wool socks, hiking shoes, coldweather-gloves
