Unless you really want to shoot macro it's an absolute no brainer, the 30/1.4 is a full 2 stops faster.... what's there is think about ?

I really love the images I've seen from both lenses, but the sigma is only sharp in the center. It shows strong border softness. That said, it's probably fine. I'd love to have a sigma 30 for candids of my daughter, but people do say it's not a landscapers lens.

So what's the problem? I use the Sigma for candids of my daughter (sometimes even for landscape when I don't have anything else), 16-50 for landscapes

If you want to isolate subjects and have shallow DOF get the Sigma 30mm, for macro and landscapes get the 35mm

Sigma 30 excels at isolating subjects from the background.
It gets the previously said job done unlike any other lenses I've used. Best 3D effect from lenses I've used so far.
Not to mention Shallow DoF and amazing sharpness in the center.

DA 35mm f2.8 is more versatile.

The Sigma may be good for certain applications,
and seems to please photographers specializing in those applications,
but unless you're one of them,
you'll find the DA35 Ltd Macro to be a far more versatile tool,
very compact and sharp, with amazing rendering.

In the photograph above, the field curvature of the Sigma
makes the right-hand side sharp (at web resolution), and the left-hand side soft.
Personally, I find that effect disturbing. YMMV.

DA 35 macro - for macro, excellent build quality, superb optics, quick-shift, small size

Sigma 30mm - for thin DoF. Beware, you will also get less sharp photos, some distortion, a much larger lens with poorer build quality, and a high risk of having to focus adjust to get good AF (!). I have seen many fantastic photos from it though, but at the end of the day, I made my choice & the Sigma wasn't a limited...

I have both the Sigma 30mm f/1.4 and the Pentax DA 35mm f/2.8 Macro Limited. As much as I thought the Sigma would make the DA redundant, I've actually kept the DA because:

- it focuses closer (the Sigma only goes down to 0.4m), allowing me to fill the frame better for close-ups and photographing small objects
- it's flat field makes photographing objects accurately and distortion free possible
- bokeh is actually pretty good
- much smaller in size compared to the Sigma
- color rendition is warmer than the Sigma, which I prefer

I do like the Sigma a lot, it is brutally sharp wide open in the center and I've not had any issues with it. The wider max aperture and the DOF effects are nice but I'd give the nod to the Pentax as being the more versatile lens, perhaps because I shoot plenty of close-ups.

The Sigma can't deliver this kind of shot whereas the DA can:

Wait - which is the spanner and which is the kit in this analogy?

Personally, I'd also go with the DA35 Macro Limited. It isn't the best macro in the world (plenty sharp, but you gotta almost rest it on whatever you're macro-ing), but it excels for regular, real-world photos.

The 35mm Ltd. also might have the least LoCA (longitudinal or axial chromatic aberrations - those green & magenta-purple halos in OOF areas) of any lens currently made for Pentax. The Sigma has plenty of this in its bokeh (linked image, see holes in wood), which makes the butteriness a bit less tasty to me. Of course, I kind of just hate LoCA for being so hard to fix in post...
