"Screw drive power/speed?"


Mankato, US
          

Anyone know if the screw drive mech in the D7100 for AF-D type lenses is as powerful as the D300/D800? You'd hate to get it and find out your 80-200 AF-D, 300/4 AF-d or whatever has become a focus speed slouch!

Thanks!

Mark

A call to Nikon Tech might render an answer... Or a call to a shop that has both on the shelf.

My screw-drive Tamron 17-50/2.8 focusses faster on my D7100 than I recall it did on my D200. Is this because of the motor or better AF module? Both, neither?

Actually, why not ask Richard? http://www.nikonians.org/profile?index.php&user=richardd300

He has the D7100 & the D800...

I could not get my 80-200mm 2.8D to lock focus with the d7100 but it works great on my D300 . I tried to tune the focus but you could constantly hear and see it trying to lock focus no matter where I set the tuning at. I currently have the 80-200 up for sell to fund the 70-200mm I bought to replace it .

I didn't have any problems with the 300mm f/4d on my D7000. I haven't tried one on my D7100 but i would assume it would be the same (if not better).

I had the 80-200D and thought it was always slow even on my F4
You'll be more than happy with the AFS 70-200 and besides the IQ is soooooo much better than the 80-200
Enjoy your lens camera set up

My 80-400 seems a slower, other AF-Ds focus very nearly as well as on the D800.

Do you think the 1.5x multiplier slows it down
or just a less powerful motor?

I belive the D7100 doesn't have the screw power of the D800. But I'm talking 10ths if not 100ths of a second slower.

I don't have D800 or D300, but I can testify that D7100 focuses faster with my Tamron 90mm than my D90 does. And this lens has a very large focus range being a macro lens.
Hope this helps a little.
