"Thinking about a D7100..."


Weston, Florida, US
          

Hi all. I'm currently a D300 shooter and regularly use it with my 70-200 2.8 and 1.7tcII, giving me reach of 340. It's time for an upgrade, and prefer DX as I have the 17-55 2.8, love it and use it often.

It's my understanding that the D7100 has a 1.3 crop option. Would that give me essentially the equivalent of a 154-442?

Do I lose additional stops like I do with the 1.7tcII?

Thanks,

Barry

The 1.3 crop is just that, cropping -- the discarding of pixels. You get no magnification from it; it is the same as if you do the cropping in post-production. It will obviously change your field of view just like the FX vs DX "cropping".

Since the D7100 has more pixels than the D300, you might benefit there from the additional pixel density for more detail in cropping.

The only benefits to using the "additional" 1.3 crop factor is a slight increase in the "Frame Advance Eate" DX Jpg or 12 bit NEF 6 frames for second and at the 1.3 crop factor, 7 frames per second. Also, the files will be smaller on your memory cards. Otherwise it's more convenient to crop in post processing to the same size image.

IRT the 1.3 crop, here is an example. I took these frames with an 18-55mm zoom @ 46mm. DX on the right crop mode on the left

Thanks for the replies...I can see the advantage of cropping PP with the d7100.
