Elk at 300
yards, not feet, though I have taken shots when they are only a few tens of feet away (depends on how close they are to the road/trail). I'm lucky to live where wildlife can be close, both to the camera and to the house (don't have to drive far).
Keeping the aperture requires a killer lens, which I know you have, Amir! For those who might not be aware, full frame helps because the larger pixels provide lower noise, allowing you to take better advantage of that aperture, and of course wildlife shots in the wild tend to be at dawn and dusk when light is at a premium as well. I'd love to have a 500 mm L-series lens, but my son needs a new used car... I should start another thread on what inexpensive tele to get. If I go the 5D route, I'll get it with the 24-105 mm f4/L "kit" zoom, but need to pick up a longer lens. Probably not the 500 mm, but some sort of decent 100 - 300'ish zoom. That's one thing nagging me to act; Canon has rebates if you buy lens and camera together by the 30th.
I have Adobe Photoshop CS2; have not upgrded in a while because frankly I don't use it. Hopefully the new camera will spur more use, but of course there are always time limitations. I am seriously considering getting the $100 "lite" version. CS2 is on my old, dying notebook and when I tried to xfr to my desktop (also old but not dying, at least not yet) Adobe said I had used both installs. Probably on my previous desktop, tossed when the HD crashed and graphics card fried taking power unit with it. I called Adobe and was surprised they would not provide a key; they said I would have to buy new. I asked if I could just upgrade CS2 to the latest and they said sure, for $500. I gave up. I strongly suspect the customer service rep I got that day had excessive blur applied.
I don't get out often, but when we do it's often one of the local parks or to hike one of the local trails (we even have Mt. Herman just a few miles away

) so the weathersealing of the 7D or 5D is appealing. I have read mixed reviews about whether it really matters for the casual hiker, however. I am not a 10-20 mile a day guy (ok, might hit 10 on a hard day trip, but I am not a backpacker).
Still cogitating...
