Two reasons. One is that it's not FF because Canon can't process
that size of an image, at that bit depth, at 10 fps. Yes FF would
be better than 1.3x. Unfortunately at the moment you have to pick
-- great high ISO images at FF and 4-5 fps -- or great high ISO
images at 1.3X and 10 fps. Then again, don't you think that either
of those options beats lously high ISO images at 2X?
The second reason is that a larger sensor costs more. Putting a FF
sensor in the camera would significantly drive up the price, which
isn't normally warmly received.
Hmmmm......... Now that I think about it, you Nikon guys don't seem
overly bothered by getting ripped off when you pay so much for
those small 1.5X sensors. I don't think I'd be enamored of paying
for five pounds of sugar and getting three.
Why not someone here in the Canon forum? There have been recent
threads touting the merits of FF... Yet Canon's newest "marvel" is
a crop job.. You certainly have to admit this is interesting to say
the least. I would like to see some Canon users comment on this..
Expecially all those that commented in the FF vs Cropped sensor
thread..
