Canon has a camera for just about every price range.
The A75 and A85 are almost identical except for the 1 megapixel. Here is a comparison chart:
3 megapixels will produce an excellent 8x10 print.
The camera companies are in a megapixel race and you don't have to join in the race.
As far as being obsolete....who knows?
The Canon "A" series of cameras has been around for a long time. My brother still has his A60 and loves it. Most of the camera companies will be announcing new cameras in late February.
We are getting ready to purchase our first digital camera and I'm not sure whether to go w/Canon A75 or A85. I know the main difference is that the A75 has 3.2 megapixels and the A85 has 4, but I don't understand how much difference that makes. We want to use our camera for family photos and travel, and would occasionally make 8 x 10 prints...
I am leaning toward the A75 b/c it's less expensive but don't want to buy a camera that will be completely obsolete in 6 months. Any advice would be greatly appreciated!
