Recently, I got a good deal on SIGMA APO 1:5.6 400mm, but not sure that would AF on Nikon D700, anyone knows how to check that? I tried the web site, but this lens had discontinued for long time.

It's a white colour lens if that helps.


thanks in advanced.

Well I have got an old Sigma 400mm f5.6 APO lens in the storage room that works on my D700 and D3 but it sure isn't white in color. It is black with white printing on it and a large gold type "APO" on the barrel near the mount, about 7 1/2 inches long.

does it do AF?

You might need to send it in to sigma to get it chipped properly so that it will AF properly..

so all Sigma/Tokina/Tamron lenses will AF?

No, I'm assuming that it won't. I don't know honestly. Just that older Siggy lenses wouldn't AF properly all the time with newer bodies... So that's why I suggested to send it in and tell them that you want it working with your D700
I assume that the lens is a AF lens... And that it's also F-mount...

It does autofocus, I was going to ebay the lens when I found it in the equipment closet but I put it on the D700 and it worked so I thought my son might like to use it for his birding and he has on several occasions.
