Hello,
For those who've owned this lens, would it make a good compliment to my DA 20-40? Thank you.

It definitely would, minus the WR factor. I own both. For a wide angle zoom lens it delivers fine performance. However, the Sigma 10-20mm f/3.5 is also very good, and I see currently it is less expensive. It is a bit larger though, with an 82mm filter size instead of the Pentax lens's 77mm.

Mike,
I have the Sigma 10-20 3.5 and there's way to much distortion at 10mm. How about the DA 12-24, is there distortion at 12mm? I really don't know how to deal with it in Lightroom, nor do I want to be bothered with it.

The 12-24 is an excellent lens. What kind of "distortion" are you referring to? Wide angle lenses, by their nature, naturally will cause buildings to "tilt", etc.

I shoot my K-1 and 15mm and get none. That's where I want to be.

Trees leaning in landscape shots. I didn't get distortion with the 15 mm limited on my KP.

That tall building and interior look great.

As a bonus, Terry, I know you also have a K-1, and there will be some times when you don't want to lug that 15-30mm f2.8 around, the DA12-24 will work for you from around 17mm up.

Thank you, Clackers. So it's 17mm without any distortion. I may just get the 15mm Limited. Theres no distortion with that on my KP. I just don't care to mess with it in post, which is why I don't have the Irix 11mm for my K-1.

Not distortion, Terry - vignetting.

Distortion is a whole other topic, reflected in choice of lens, your camera placement and orientation with respect to the subject, and post processing. Even the DA15 will do it on your KP, it would take about ten seconds with your camera to demonstrate that.

Got it. I realized what you were saying after I replied. Thanks.

There's a bloke who loves his cakes, never mind the perspective geometry … he really doesn't need the camera 'adding five pounds'!

Beautiful, Brooke.

I have decided to keep the Sigma 10-20, and ordered the 15mm Limited. Does it make sense, no. I just wanted the 15 Limited, and I'm sure the Sigma will be fine, once I learn to use it.

I get a much better IQ from my DA12-24 than I do from my copy of the DA15, especially at wider apertures. As far as I'm concerned all the DA15 has going for it is its small size. I find it far too unpredictable. Best of luck if you plan on not doing any post-processing.

I think that shot is beautiful. Well, the tweeked version, anyway. I just like the Limited lenses. It seems like many people with a cropped sensor body has it.
