Hi! i'm new!
This is my first time in this forum.
I'm a happy owner of a k20d, and in these days i'm thinking on buying a super wide-angle lens.
I'm thinking on Sigma 10-20, but I need your help.
Does anybody know if this lens for pentax DSRL has the HSM or not?

Thanks guys!
It doesn't have HSM, at least not the one I tried at a local shop. But who needs focussing at 10mm f/4 DOF will be roughly from you nose to the moon at any focussed distance

I think it is EX (not DG, though, so for crop sensors only ) and relatively heavy.

Nice to hear! the EX is the range of better lenses at sigma right?

The new sigma 50 1,4f EX had wonderful reviews I hope that the pentax DA*55 can get the same

The Sigma 10-20mm and the DA 21mm are both excellent choices. I can't see how HSM (whatever) is important for landscape purposes.

I thought the same. I almost prefer manual-focus so I don't even have to think about the autofocus bother me trying to capture the photo

I am using the Sigma 10-20 all the time for landscapes, if I don't reach for primes. It is versatile, well made and has very good image quality. It is comparetively small for its reach, which for me is a big plus. The Pentax 16-50 I recently got, also is an excellent performer and I adore the silent SDM drive. But as others already wrote, for landscapes, AF is of no importance.

I very much doubt, we'll ever see the Tokina 11-16/2.8. So far no recent Tokina lens was released with Pentax mount. And if Pentax had co-developped that lens (as was the case with several other Pentax/Tokina lenses), I guess, we would have already seen the Pentax incarnation.

Older lenses, that would be very good choices include all flavours of the Pentax 15/3.5 wide angle, which is simply stunningly sharp (but prone to flare). Also of interest might be the old 16/2.8 fish-eye lens, which isn't too fishy on the APS-C sensor and needs distortion correction, but is very sharp for such a lens. There are also some older K and M wide angles, on which I can't comment, which have good reputations.

I'm another member of Sigma 10-20 club. As for HSM/USM whateverSM, it doesn't bother me too much. I usually (95% of shots) use it on 10mm f5.6 MF on 1m mark. Results: didn't have many bad shots. It's really sharp and it's FOV is great. Plus it's CA and PF are very well controled.

Totally agree with you Axl.
This lens is very "forgiving" I found.
