D7000 vs D7100 - D7100 grainy background
Mar 16, 2013

I picked up my D7100 on Thursday and proceeded to set it up the way I had my D7000. Since most of my shooting is nature/wildlife, I like to use the Landscape Color control, with one notch extra contrast and saturation. On the D7100 to me it looks like I need one notch extra sharpening also. These settings are for what I typically like for jpgs right out of the camera. Though I typically will also postprocess those I like best.

Anyway, right from the start my D7100 images looked on the grainy side, which made it more difficult as I check AF Fine Tuning. I ended up an +4. My D7000 is set for -3 as default for any and all lenses as that is what I kept coming up with, and it works great for the lenses I have rented (300 F2.8 and 600 F5) as well).

Now with that, since it is a rainy day, I set up a stuffed wolf, with my 70-200 VR II, on a tripod and put the central focus point on the eye, then shot with both the D7000 and the D7100, each on ISO 100 and no exp compensation. Have a look at the following two crops. The JT7_0728 is my older D7000, and the J71_0127 is my new D7100. Notice both that the D7000 image is slightly lighter, and that the D7100 image is noticably grainier.
