I am having trouble deciding between the D7200 and the D610. I am upgrading from the D3200, so both camera would make a great difference.
At the moment, I have four lenses. The 70-200mm f2.8 (tamron) and 50mm f1.8G. The other two are for dx and I don't use them anymore.
Next year, I will be the photgraph for the sports at my local college. Which are hockey, football, soccer, basket ball and volley ball. I also want to shoot music shows and open a little studio to do headshot at home.
I would like to go full frame for everything other than sports, but I feel like the D7200 would be better for sports than the D610.
What do you think would be better?
Could the D610 be enough for sports?
I am really having hard time choosing.
Thanks in advance and sorry for my bad english.
I am not sure how are you shooting sports, but when I am shooting actions, I am doing quite much shots for every action continuously holding camera. Later I am choosing the best images. It means you need camera with great continuous FPS. Both nikons have 6 fps, so at this point there is no clear winner.
Here are good technical comparison pages:
Do not look at overall assessment as you need to shoot sport.
The other parameter I would consider is weight. You will stay with camera prepare for capturing images around one hour (effective). So the lighter camera the better. Also lenses for full frame cameras are usually heavier.
The next is max shutter speed. Hockey is played in the very good lighting conditions in comparison to concerts, so you will be able to reach very high shutter speed, I cannot tell if you will for sure shot 1/8000, but it could be.
So for sport I would get D7200, this one is also cheaper, so when you destroy it somewhat, you will less cry :-).
The problem is that you mentioned as well concerts. This is completely opposite lighting situation to hockey. Poor lighting is really bad for smaller sensors. The parameter here is called low light ISO or effective ISO. So for the concerts I would choose D610.
Now is your turn. Check how many concerts per year you will attend and how many sports events, then decide on one or the other camera. The feeling I have from your description is that you will attend more often sports events. But you need to check it with your college activities plan.
BTW. Buy additional accu and as fast as possible memory card(s) - it will pay off.
Not related to details of your question, but have a look at comparison 10 Recommended Cameras for Sports, Wildlife, and Action Photography
Both cameras have strengths and weaknesses for the various shooting scenarios you have mentioned. It's up to you to decide which features are more important and thus work better for you.
From personal experience I can tell you that 200mm on a FF camera is not long enough for everything you'll want to do with football or hockey, much less soccer. Even with a DX body you'll be cropping a lot with a 200mm maximum focal length. You'll also need something with a wider FoV than 50mm (in either sensor format) for some of what you'll want to do with basketball and volleyball.
Fast glass is paramount for shooting indoor and night sports. Ditto for concerts and theatrical work. Anything slower than f/2.8 is marginal, although at wider angles of view you can sometimes get away with f/4. Fast, reliable AF is also important. The older Tamron 70-200mm f/2.8 Di LD (IF) Macro has a reputation as a slow focuser. The newer Tamron 70-200mm f/2.8 SP Di VC USD lenses (both the original and the new version 2) are much better in this respect.
If one camera you're considering has a "flicker reduction" feature that times the shutter release with the peak in the light cycle of flickering stadium and gym lighting and the other doesn't, that would probably be the tipping point for me. It makes a huge difference! Nikon is now offering such a feature with their top tier bodies, but I'm not sure if either the D610 or D7200 have it. The D750 & D500 both have it. The D610 has a feature in movie recording modes named "flicker reduction", but it doesn't appear to be the same thing.
