I'm looking at a digital camera... I've narrowed it down to the Canon A60, A70, A75, or A80. The megapixel difference is 2MP through 4MP on A80. Otherwise they are pretty much the same camera. Ken Rockwell (photographer) argues here: A60 vs. A80 and here: The Megapixel Myth That I'd be just as well off getting an A60 as an A80. What does your experience tell you? Is this guy loony or not? I'd love to be able to print out the ocassional 8x10, though that would be the exception... Opinions??!!
