Sigma HSM /AF on Nikon DSLR

Unless they get too big for themselves, this is where you can talk about the "other" brands of DSLR's: Konica Minolta / Sony, Pentax / Samsung, Olympus, Horseman, etc.

Sigma HSM /AF on Nikon DSLR

Postby idleowen on Thu Mar 20, 2008 5:05 pm

Hi,had a question on a newly purchased Sigma 10 - 20 lens,for my D80,hoping somebody might be able to offer some advice / assurance!
I'm used to the Nikon 18-200VR lens for focusing,when it correctly focuses on the subject(still object),repeated half presses of the shutter doesnt seem to prompt the motor to activate,indicating locked on focus.With the Sigma,on a still object,it emits a motor engagement noise as though its repeatedly trying to focus/refocus but the green viewfinder light stays green. Doesnt seem to shift the lens barrel to 'hunt',pictures are sharp.Just wondering if this is a Sigma HSM trait?
thks in advance!

I used to have this lens, and cant recall having this problem.
I have a 100-300 f4 HSM lens currently and it only makes motor noise when trying to focus or shifting focus from one position to the next.

I have the EX APO DG 180mm f/3.5 Macro, never noticed this problem, but I guess a macro is a very different story. My experience is much like ljxphotography, no noise if no shift in focus.

10-20mm will work different to 18-200mm,,.... you will not notice the small shift in focus as with a wide angle the shift in focus is quite small unless you move from something close to far away.........

Its a common issue with this lens, nothing to worry about. Mine had the same 'small focus hunting', you just get used to it over time.
