[QUOTE="Fortkentdad, post: 556227, member: 24285"] Short answer, maybe. More mega pixels to begin with will give you more latitude in cropping. The AF-D does not autofocus on a D3100 so you are focusing manually - which is wonderful if you have mastered that skill. But it does introduce a margin of error if you move after focusing. And depending on the aperture your depth of field will mean some will be in better focus than others. If you know you are going to crop shoot at a higher aperture so front row and back row are both in your focus plain - F2.8 is great for low light and that loverly blurry background. But not for mega cropping. But before you go out and buy a more expensive body for more pixels and a AF-S lens, Jim's post above makes an excellent point. If you want a single person shot - shoot that person. Cropping is always going to cost you in IQ. There are times when you have to and it is a tool in your bag, but use it when it is needed.
