7100 focus motor strength
Has anyone used some of the older lenses that are driven off of the focus motor in the camera on the D7100? I'm thinking of moving from the D200 to the 7100 and the D200 drives my old 80-200 2.8D very swiftly. I'm curious if the 7100 is as strong or at least pretty close.
I recorded focus speed with D90 and D7100.
I used nikkor 80-200 2.8 AF D lens and sigma 70-200 2.8 D lens.
Hope it helps:)
I have a screw drive Tokina 50-135 f/2.8 that is somewhat pokey in the AF department - just barely too slow for sport, but an awesome lens for portraits. However I shoot kids at events quite a bit and I need that AF speed.
The D7100 is noticeably slower than the D300/D200 bodies when AF with this lens. That does not mean that it is very slow or unusable, but there is a difference. The D7100 seems to be about the same as my D7000 and D90 when AFing with this lens, but I never had all three cameras at the same time to do actual controlled measurements.
I vaguely remember that the grip may give a bit better motor torque/speed, but cannot remember if that was the D90 or D7000 where I read about that. It may or may not apply to the D7100.
Ok, thanks. I really need to take my lens to the store and see how it does.
