Does anyone know what the EX DC HSM at the end of the lens description means?
Would the above lens be compatible wih a Pentax K10 camera?
And lastly, what focal length lens would complement a 10-20 in a landscape photography kit?
Many thanks for any advice offered.

EX - Sigmas top lenses, best glass 'pro' lenses
DC- Only works on cameras with an APS-C sensor ie the ones with 1.5 or 1.6 crop factor
HSM - Hyper Sonic Motor. Fast silent focus. The equivalent of canons Ultrasonic motor. Dunno what the Nikon and Pentax equivalents are.
As to the other questions I'll let someone else answer them
If you go to the Sigma website, it'll tell you everything, just click on the tabs for the pop up menu.

I think you just need the 10-20 and that's it - spend the rest of your cash on Cokin X-Pro filters
Agree, but sometimes a longer focal length is handy - perhaps the Sigma EX 20-40mm would be a suitable companion?
I'm eyeing one up on ebay to use on my film cameras....though they work with digital too.

Nikon = AF-S
Pentax = SDM
Nikon equivalents are bloody expensive.
By the way just got the 10-20, in a word, fantastic, solid, clear, inexpensive, fast, super wide, ok maybe a few words.
I have the 18-50 ex as well and have found that ok for landscapes but almost always at 18mm hardly anywhere above that, so if it where a choice for landscapes defo the 10-20.
I use Sigma 10-20 & I think it's the best Lens I have.
I use a Sigma 10-20 on my Canon 30D, really pleased with results that I get with it. Nice to use and great for landscapes.
Much better colour and sharpness than a Sigma 28-70 f2.8 I have recently purchased.
As above, I have the Sigma 10-20, not just a landscape lens, but alows you to get up close on subjects, and is my most used lens, I thought about the 20-40 Sigma, as a partner to it but on a 1.6 crop I opted for the 18-50 2.8 EX, to get that little extra at both ends,also a very sharp lens, the 2.8 is good on walkabouts.
k 10 + 10-20 Adrian
I have 10-20, which is a fantastic lens (and much used/owned on this site). As a "partner" lens to the 10-20 for landscapes, I'd opt for a tele photo to pick out parts of the landscape. It also gives you the option to capture wildlife. I also use a Sigma 70-300 lens, which has a macro option.
I have the Sigma 10-20, its a lovely lens, i use it for landscapes mostly, perfect. i also have the Macro 105mm lens from Sigma, again a very nice lens. back in the 70's sigma was a brand most of us avoided, the quality was not there, but now they are up with the caamera makers lenes, and sometimes better than them,
Best lens I have never used

A telephoto - to pick out details. Which one? deepnds how much you are prepared to spend.
