Well I have been looking into which camera I should get the 40d or the 50d and one of the issues I'm debating is print. Not just quality but size. I'm use to working with applications for print such as illustrator and 3dsmax where pixel lost is not really an issue. So I'm use to getting large prints. Usually about 24x36 sometimes larger. I have a cityscape that is 2ft x 9ft. So I'm kind of leaning towards the 50d do to the greater number of megapixels. However, I have been told that when it comes to print it's not all about megapixels but quality of image as well. Having seen a 40x60 print from a 8mp camera I can vouch for that fact. One thing that does confuse me is the issue with the 50d and the optics. I've read that to take full advantage of the 50d's 15.1mp sensor you need really good lenses. The salesman at my local camera shop told me that while that's true a good lens does not necessarily have to be an expensive lens and recommended using a EF 50mm F/1.8 till I can afford a good zoom lens. So I'm curious if that's true? Also, if someone could explain this issue it would be greatly appreciated.
