Sigma finally did it! They're beginning to offer new lenses with HSM for Pentax cameras! HSM will work only for cameras that support HSM/SDM (i.e the K100D Super, K10D, K200D, K20D), otherwise the lens will not autofocus (as there is no slotted screw drive).

Here's the list of lenses announced with links to the news release:
---------------------------------------------------

APO 150-500mm F5-6.3 DG HSM
http://www.dpreview.com/news/0801/08...igma150500.asp

APO 120-400mm F4.5-5.6 DG HSM
http://www.dpreview.com/news/0801/08...igma120400.asp

APO 70-200mm F2.8 II EX DG MACRO
http://www.dpreview.com/news/0801/08...0050150aps.asp

APO 50-150mm F2.8 II EX DC HSM
http://www.dpreview.com/news/0801/08...0050150aps.asp

18-125mm F3.8-5.6 DC HSM
http://www.dpreview.com/news/0801/08...sigma18125.asp

Very exciting to see Sigma getting serious about supporting Pentax!

At the time I don't plan to buy any fast telephoto lens. I wonder how the 50-150 f/2.8 is going to stack up with the Pentax DA* 50-135. If pricing is the same with the other big two, the Sigma should be a little bit cheaper and it has a longer range.

If I was going to get one out of those 4, I would go for the 70-200mm. Although the 50-150mm would be a nice match to go with my Sigma 18-50mm EX DC.

Hmmm - more options out there. The 70-200 f2.8 sounds interesting, but I'm not sure that I want to give up the ability to use AF if I were to use the lens on the K100. On the other hand, maybe the APO 120-400 with HSM would be even more promising (but I dont' think I can handle that long of a lens). All these new lenses sound like my budget is going to be forever into the red.

Very nice that HSM is now no longer a deciding factor between Pentax and the big two

Hopefully this'll drop the price on used 70-200mm f2.8 lenses a little.

I see the Long end of the 150-500 has a slightly wider Aperture. (6.3 insted of 6.7) just a tad faster!

Some of teh new sigmas have optical stabilisation built into the lens.

Do you have to pay for that with the Pentax versions and then not use it?

I was reading about that, but wondered if they would just leave it off the Pentax and Sony mount lenses. I'd be really interested to have one with it - I'd love to play with it and see if the in-lens VR would be more effective for me than the in-camera stabilization. And I wonder if the two together would work with each other to give you a better picture in marginal conditions, or work against each other.

The lens-built in SR only apply to Nikon/Canon mount. Not Pentax mount at all
