Still testing the D7100 with the 300 f4 + 1.4 TC in 1.3 crop mode. I was driving the backroads around home & shot these handheld through the car window. I couldn't get out as they would have disappeared in a flash. It made for a difficult shooting position. They were backlit so the correct exposure is just not there yet. Technique still needs work & lots of practice. However, with each outing I'm feeling more comfortable & liking the D7100 more & more...the D200 is slowly receding into fond memories.
