D7200 has bigger buffer, better low light focusing, a little less noise at high ISO, and a little better dynamic range. The D7100 is $200 lees, or $500 less if you grab a refurb. They are both great cameras.
Over and out.
Same here.If I were upgrading and buying new, I'd opt for the D7200.
Biggest differences between the two is that the D7200 has built-in Wifi and NFC, better IQ with the new processor and sensor, much higher ISO range, better low-light capabilities, much better AF and much better buffer size.
Is that all
