I thought seriously about getting a Digital Rebel - I've seen some
stunning images from it on the 300D forum. However, from the
associated comments, I gathered that getting those images often
took more fiddling than I'd have the patience for. Also, I didn't
like the idea of carrying around a camera that big and heavy, plus
all the associated paraphernalia (lenses, flash, etc.). That plus
my Powerbook plus my Treo plus the medications for my bad back
would be an awful lot of stuff to take through airport security
lines.
I've only had the A1 for a day or so, but so far I'm quite
impressed. Its focusing is about 10 times better than the G2's,
its colors are more accurate (something I hadn't expected), it has
a
lot less chromatic aberration than the G2 (and a lot less than
the kit lens for the Digital Rebel). In addition, I really like
the larger zoom, the heads-up information in the EVF, the zoom ring
and manual-focus ring, and the better ergonomics (fits the hand
better, and most functions are available through buttons and dials
rather than having to hunt through menus).
There are a few things I miss about the G2, the main one being that
its images are less noisy than the A1's - but I knew about those
things before ordering the A1, and decided that under the
circumstances, it was a good tradeoff.
Former G2 owner, tired of bad focusing and limited
lens.
Don't want to carry around a bunch of lenses (changing
the Lensmate and putting on lenses on the G2 was
a pain and the camera just looked weird).
Great focus for action shots -- I am amazed at how well
the A1 works in this category.
Great battery life -- I'm using the BP400 and the NP400s...
