So I am working on going to school for photojournalism and when I talked with a pro she was not happy that all I had was a D7100. She told me I should have bought a D610 or some other full frame body instead. Not being anywhere close to a professional I don't exactly have the budget or the reasoning to buy a good full frame at this time.
What do you all think? Should I have bought a full frame over the D7100?
You made a great choice, you did NOT make a mistake.
I have both DX and FX, and let me tell you, FX and its lenses are a big, heavy and very expensive choice.
It WILL get your attention.
DX will show a longer view (a little telephoto effect, the 1.5X crop factor), so you only need a 200 mm lens instead of a 300 mm lens (for the same view). This is great for wildlife and sports.
The FX will show much wider view (the 1X crop factor I guess), so with FX, your wide angle lenses will show a much wider view.
Other than that, the big difference is the expense.
Just saying, when you actually have a reason for FX, you will know it. By then, there will be new models available. Meanwhile, enjoy, you surely have the best choice.
