what gives?... how darn big do I need to print???? I really want to justify the more expensive sharper lens but I need to SEE the difference. How big? 48x80? help me out here guys.... when is sharp just not sharp enough?... for prints?
yeah, I can't see any differences when printing stuff in my house unless if I am really looking for it. certainly hung up on a wall there's no way anyone would see any difference. so, if your only goal is to print stuff for your own pleasure, it seems clear to me one doesn't need very best lenses, at least sharpness-wise. and that goes for those ultra-high resolution cameras too like the d800. if going straight to print it doesn't make much of a difference, even enlarged quite a bit.
however, in these types of arguments one thing that doesn't get much attention is the ability to crop. the sharper it is from the source, or higher the resolution, the better your crops would be, and the more you can crop. that is a huge advantage for composition or editing. we're not all perfect photographers who get all things right in a shot. when I get home I almost always like to tweak the images a little to maximize effect.
but yeah, if you don't edit, and just take pics to print for your house, you can spend 1/2 as much on equipment.
there are plenty of folks at work that LOVE to print out pics of their baby kids from crappy printers on crappy paper and post them on their cube walls. they'll also post heavily compressed images on facebook of the same kids. I can tell they use slrs with large apertures, but sharpness is totally irrelevant in those uses.
