You guys are wasting your time with this pixel peeping bullS___ and sensor S___ that you guys are talking about. First, not because you have a full frame sensor does not mean that you can produce a better picture than someone that has APSC size sensor. Second, lens matters. Even if you have full frame camera but has only a mediocre lens in front of the sensor, the resulting image is not as good as let's say, a T2i with 85mm 1.2L or a 70-200 IS II. And lastly, if you are really a good photographer if not great, then any of this camera and lens S___, will mean nothing to you. What do I mean by this? There's a lot of ingredients that involves in photography more than just a camera and a lens. One does not make a good photo just because he/she has the top of the line camera and lens.
