Dance Concert D7100 vs. D610

Last December I shot a dance concert with the D610, and while I got some very nice shots, I was disappointed with the focusing system and made a note to try the D7100 next time. Well, next time happened earlier this month.

These concerts are always both stressful and fun. I’m not sure there’s any focusing system that would be optimal in these circumstances, but the D7100 definitely did a better job than the D610, and I got well over 150 keepers from the first performance. But you know what? I just couldn’t leave well enough alone.

While I was over-processing, pixel-peeping, and over-analyzing images from night one, I decided that I had sacrificed dynamic range and low-light capability by choosing the D7100. I resolved to shoot night two with the D610. It’s a good thing I got most of what I needed on night one.

Now don’t get me wrong. I got some good shots with the D610, but it was more of a crap shoot, focus wise. I knew that I was trading focus acuity for lower noise at higher ISOs, but I was surprised at what a bad trade it turned out to be. There are several factors at work here: 1) the D610 doesn’t focus as well as the D7100 in low light, 2) the full frame sensor produces less depth of field at the same aperture, 3) the full frame sensor also required me to use the lens at its extreme end of 200mm, where it is less likely to be sharp than in the middle of its range. (I haven’t tested this, but it’s a plausible hypothesis). Whatever the reason, the images were not as sharp as often, and that was a shame, because the dynamic range and high ISO were visibly better.

As I say, I got most of what I needed at the first performance, and the teacher is happy with the 198 images I delivered. This experience reminds me to carefully choose the right tool for the task at hand. One week after the dance concerts I did a studio shoot with the D610 and cannot imagine a better camera for the job (blog to come).

So the very good news is that I got to see these magnificent dance performances, make some very nice photos, and learn something important about my cameras. Win, win, win.
