Still, I was in need of a replacement camera, since we are going to Africa this summer and I've already exceeded the rated shutter counts on both D300's we have. So, after much research (pondering a 36MP 'FX' D800e or a 24MP FX D600) I opted to pull the trigger on the D7100. A trip to ProCam in Livonia, and a great deal from George, I was now a D7100 shooter.
What I did find, however, was an unusual number of soft images that had me questioning whether the focus calibration needed adjusting. For the next 3 hours I 'fought' the menus of the camera trying to adjust the focus so that I calibrate focus using a calibration chart. The camera kept selecting the bottom left corner focus points, and I couldn't figure out to center them. After RTFM I finally found the menu options that would allow me to set center focus and focus area so that with a half-press of the shutter I could lock focus on the center of the screen. A quick check of the focus calibration returned a value of +0 (no adjustment needed!).
I don't think moire is going to be an issue (not having the AA filter), so I'm extremely pleased with the performance of this camera. I'm looking forward to getting the battery pack so it'll be a bit more stable w/ the 300/2.8 VRII. I'm looking forward to getting out this weekend to try my hand at birds in flight w/ this combo. Stay tuned!
