specific lens for *ist D

I am after some advise re the lens compatibility for the *ist D

I wanted to double check that it is fully compatible with my Sigma lens, specifically...
Sigma UC Zoom 28-70mm 1:2.8-4
Sigma DL Macro 70-300 1:4-5.6
Sigma Zoom 18-35mm 1:3.5-4.5

They are K-af Bayonet mounted lens

I am assuming that they will work with the *ist D but do they need any special mounts etc? Are then any issues with auto focus vs manual focus?

They will all work a treat

No issues whatsoever, just the 1.5x focal length (so the 300mm end becomes 450mm).

excellent! just the answer I was after

thanks
