Jellyfish - This is where my wife and her D7100 kicked my D600's butt! The FX D600 is a better low light camera than the DX D7100 camera and does better at high ISO's. However, and mind you this was not scientific, the wife was shooting jellyfish and just firing away. I'm standing there with my D600 zooming in and out trying to focus. Finally, partly out of frustration, I asked her if she was on manual focus (accidentally) and that's how she was seemingly getting all these pictures. She was auto focusing and absolutely killing me. Trying to figure out if it was the difference in lenses, Tamron 90mm on mine and a Nikon 40mm on hers, we swapped lenses. Nope, it was not the lenses. The D7100 auto focus hands down kicked the snot out of my D600's ability to auto focus in low light. I did not expect this, and my wife tells me it's simply because she is a better photographer. Whatever the reason, I felt like I had a knife at a gun fight. Here is what I manually focused and shot.
