Im looking for something that takes great photos and has decent HD. Therefore I was mainly looking at the D-90 and the canon 1ti i belive it is. And i'm not sure about what lense i should aim for, im new to the lenses and stuff so im not sure what the different lenses you can get with them are for. any help, other recomendations or opinions would be great. And which out of the two would be best or a third option?
