I will own this lens for anime convention photography if the reviews come in as positive for it. So, who is getting it first and posting a good review of it here?

I would like to have this lens too, specially if the promised DA Limited zoom FL~20-40mm (Roadmap 2013) does not comes out as promised this year.

after scrutinising some image samples taken at f/1.8~f/5.6 range I can say the FA31 can rest easy.
I realize that there's "more to it" than resolution but, according to Lenstip, the Sigma 18-35 is 20lpmm sharper than the FA 31 wide open and is as sharp at f/2 as the FA31 is at f/4-5.6. The thing is huge however, as big as the Nikon 24-70, so there's that to think about among other optical characteristics.

And price...you can get a brand new Sigma cheaper than the 31mm LTD

I think all things Zeiss and Leica are of more interest to collectors, several of the lens collectors I know have an almost fetishistic view of Leica cameras. Frankly, I find it to be a bit disturbing. I really don't consider cameras to be objects d'art....they are tools, nothing more.
I have a Lumix P&S with Leica written on it. When people try to sell me Leica products, I tell them that I have more than enough already.

But the astigmatism from the sigma lens is higher, coma is also worse, as well as across the frame sharpness and flare tolerance - Sorry, but the FA31 wins by a considerable margins as far as those optical performance characteristics are taken into account. A lens with fewer lens elements in it will always beat a lens that has more when it comes to managing flare*.

*assuming the optical coatings on the lenses are identical - in which case they probably aren't. Sigma has always lagged behind in this area.

Good point, I had forgotten about that one... Let's hope the new DA Limited lens will come soon enough, and we'll compare then. In the mean time I'm hoping my DA*16-50/2.8 will hold out till then.
OTOH, I doubt the DA limited will have as large an aperture as the Sigma 18-35/1.8, Pentax having oriented the DA limiteds towards small size rather than larger aperture (like the FA limiteds).

Didn't Hoya 'help out' Sigma with their lens coatings during their Pentax ownership period?

Nah, probably Pentax will just make it up to F4, just as like the beloved FA 20-35mm (with SDM) to justify the skyrocket asking price

Or worse, it will stay on that roadmap forever.

Should Pentax release their promised lens, I hope they make it ASAP because the Sigma lens will be definitely a looker and much cheaper too.

The thick cynicism in this post represents a big problem for Pentax. They have lost the confidence of many of their loyal customers that they can be competitive in the lens business. It's this kind of perception that can kill the brand.

I would say that without the support of Sigma, there is very little chance that I would have stayed with Pentax. I hope they do turn things around, but at this point I don't have much confidence in the leadership at Pentax.

This is spot on. There is very little faith among the brand loyalists.

TBH, I'm a little tempted by Sigma's own DSLR offering, the SD1 Merrill. I would just have a hard time justifying the switch, considering that I already have one of their compact, fixed-lens cameras, which uses the exact same sensor.

I should add that I'm no brand loyalist. I would switch if I was really disappointed with Pentax, but I'm not. I'm still very happy with the K-5 IIs, and I don't feel limited by the lenses I can use. Far from it.

If they did, I certainly didn't notice any improvement with my Sigma 8-16mm f/4.5-5.6 - the DA15mm f/4 Limited puts that bulbous lens to shame when it comes to flare control.
