A Meaningless Experiment

I was setting up a few lights at home to shoot pictures of my daughters, and I took the picture you see above while testing the hair light, you can see it is quite hot (I ended up reducing it by one stop), and what you can't see, is that it is causing lens flare, because it was not gridded.

Nikon D600 vs. Nikon D7100 comparison (daylight)

While I'm still analyzing the D600 and D7100 low light shots, here are more comparison shots between the D600 and D7100, this time in daylight.  For this test, I used the Sigma 35 1.4 on the D7100 and the Tamron 28-75 (at around 52mm) on the D600.  I know, your first reaction is that it's not a fair comparison because the Sigma is considered one of the sharpest lenses, whereas the Tamron is sharp in the center but it's not in the same league.
