Is it worth getting 4 megapixel, or ir 3.2 way enough? It's going to cost me 560$CAN to get a A75, I'm telling myself that since it's already quite a lot, 100$ more won't kill me, and I won't regret buying the 3.2
Good point. If you want some really nice pics, the 4.0 all the way. But if you don't care about quality all that much (yet don't want something too ghetto), the 3.2 would be the way to go.
So theorically, there wouldn't be any difference between a 3.2 and a 4.0 with 5X7 prints. So it all comes down to "do I want to print 6X8 pics". Imho. Can we see above 300dpi?
