[QUOTE="aroy, post: 295741, member: 16090"] Unless you are doing a lot of wild life and need the reach offered by the telephotos on the DX sensor; in my opinion; a D610 is a better buy than a D7100. (At least in India they are within 10% of each other). What you get with FX is wider FOV and slightly better low light capability. What you loose is the "apparent" reach of long telephotos. One place where the DX trumps over FX of same MP is when the image fills in less than the area covered by DX sensor. For small images; as in case of mild macros and most wild life taken at a long distance; the higher density DX sensor will have more pixels in the image. Again D7100 has more AF points, which are spread evenly across the image area, while the D610 has a fewer points and they are clumped together. So D7100 makes more sense if you use AF right upto the corners. In my case I am mostly limited to the centre, hence number and the spread of AF points is not that important. [/QUOTE]
