I think this is actually good for Pentax. It will force Canon, Nikon and Sony to make bigger lenses to compete with the IQ, while Pentax can scoop up the "compact" niche (while retaining 95% of the IQ and maybe having more rendering "character"). And if you want the big Sigma, you can still get it in K-mount. It complements the Pentax lineup without competing against it directly (since the Pentax 50mm lenses are so different). Nikon and Canon are in a bit of trouble, though, since this Sigma is directly competing against their large top-tier 50mm lenses (and arguably, beating them).
Well Canon/NIkon shouldn't be too happy and so should be Zeiss and Voigtlander (and Leica somehow).
Sigma wants to be seen as an Optical Manufacturer with a big O and it seems to work.
Most younger people know about Sigma but a lot less about Leica/Zeiss/Voigtlander and Sigma keeps building its image.
Well done IMO.

I have some manual lenses, 28mm/2.8, 50mm/1.4, M 50mm/2, and for me, is a pain to use it, because are so small. Even with DA 35mm/2.4 I'm feeling unsecure, cause I don't have o lot of lens body to make a good grip on it. I'm feeling OK with my Sigma 50mm/1.4 HSM, and other lenses that are bigger. So, everything depends of the size of your hands. Yes, 810g is a big weight, but is easy to handle. At least, for me.

But a price of 800-1000$, is much easy to handle that 1500.

Apparently it will be about $1000,- (or €850) http://photorumors.com/2014/04/09/sigma-50mm-f1-4-dg-hsm-art-lens-price-and-...tus-comparison

I've downloaded the test photos made by Imagine Resources, and my conclusion is that Zeiss Otus has a small advantage in contrast. Studying the pictures at 3:1, I have seen that at extreme corners, Sigma 50/1,4 Art is a little better at CA. In fact, Sigma CA is almost invisible, even at 3:1, but can be seen in Zeiss Otus.

Exceptional lenses both. But Zeiss has no AF, is much heavier, and if this price of Sigma is right (1000$), the choice is simple. I hope it will come in Pentax mount too.

Quite a lot of discussion about how great this lens is, how it's going to affect the market possibly in Pentax's favor, how it's going to compete with Pentax lenses...

... for a lens that's not even coming to K-mount.

Half don't know that, and the other half only wants to discuss meaningless statistics. Ain't it grand?

No statistics are meaningless; otherwise, we wouldn't lie with them so much.

Good point! There are a few members here with systems other than, or in addition to Pentax, though.

In case anybody's been looking forward to images of something besides test charts (I know I have), a Korean website has posted a series of samples wide-open with a 5D MkII. Allegedly. They're viewable at full size, too.

Gear for Image :: Wide Open Images of Sigma 50mm f1.4 DG HSM ART

Sadly, they don't tell you much about its OOF rendering. We don't buy f/1.4 to shoot walls wide open...

I think that is to soon to tell that Sigma 50/1,4 Art will not come in K mount ever. Other Sigma Art lenses were originally released only for Canon, Nikon and Sony, and then were made for Pentax. I think it all depends on how much demand there is. And from what I see, Pentax is gaining ground.

I have a Sigma prime for my M43 camera and I must admit I am very impressed. It's much better than I ever would have thought it would be given the price point. Very sharp, very well made, metal mount. If this lens is anything like I'll be it's a good bang for the buck.

Actually up until now, Sony was always in the same boat as Pentax for Sigma's "Global Vision" lenses. The 18-35mm was originally only announced for Canon, Nikon and Sigma. Later they announced it for Sony and Pentax at the same time. Same thing for the 30mm f/1.4 Art. The 35mm f/1.4 was finally shipped at exactly the same time for both Sony and Pentax. Neither ever got the 120-300mm.

This is the very first Sigma "Global Vision" lens that has been announced for Sony but not for Pentax. That is a very bad sign IMO.

The choice is simple?
