I just bought a Nikon D5200 and I have a few questions. This is my first DSLR and I was looking for a battery grip but I can only seem to find ones that fit the D3200 and D5100. I was curious if it would fit for mine as well, or have I just not found the right one? Also, the girlfriend and I go to a lot of car shows(inside and outside) and I go to baseball games as well, I'm not sure which lenses would be best to go with. Thanks for any help in advance!
