I picked up a D3300 a few days ago and the IQ is stellar. The new kit lens is very cool. Small and sharp.
The D7200 is going to have to be very special, because as it stands the D3300, D5300, and D7100 stand neck and neck in regards to IQ. As it is the only thing the 7100 has going for it is the sturdier build and more buttons.
For products shots in my studio I’ve been using a D5300. I don’t need a weather-sealed body nor a camera with a million dedicated buttons. Set it and forget it.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
