the one on the right with sigma 70-200mm F/2.8 HSM OS. The left is the D5100 w/nikon 50mm/f1.8. The D7100 seems like the best bang ($1100 for body only) for the buck with all/most pro features in a cropped sensor. Don't care much for full frame and having the extra reach is important to me
.Took around 300+ pics so far and it's awesome with 51 focus points. With the sigma lens, it matches my GF's brother's 5Dmark II's focus speed.
The D5100 will be for the GF to shoot. I could tell she gets bored when she's just watching me shoot.
