I've read Sigma went to lengths to minimize flare and ghosting on this one.
In my experience Sigma lenses are pretty abysmal when it comes to flare tolerance, I have two top tier Sigma lenses 100-300mm f/4 APO EX DG and the sigma 180mm f/3.5 APO EX(non-DG) Macro and neither of them handle flare as well as their equivalent pentax lenses do.

Long as in focal length? Any sample photos?
Yes, focal length. But, rereading your intended us it shouldn't be an issue. My problem is that I use it for chasing a baby and the rooms in my house are not huge so to get the baby fully in the frame I have to be all the way across the room, especially if I am shooting video.

DA 21 is in the works to cure this problem.

Yeah, that's kind of what I was afraid of. I don't know if it would matter too much, as it may not be outdoors a ton; however, I would like the option. I guess I'll rent the DA*55 and go from there.

Ah, yeah. I've got three 50s now, so I'm aware of the focal length. I don't really have anything to chase around the house right now, so I can wait a bit on something wider.

Lenstip had kinder words for the Sigma 50mm f/1.4 than they did for the Pentax DA* 55mm f/1.4, however their sample flare pictures made the Pentax look better to me. Photozone.de didn't talk about flare at all. I did find a review for the Sigma in Canon mount at another site, where the reviewer said, "Overall, the Sigma shows slightly less flare than the Canon f/1.2 and f/1.4 - and less than the f/1.8."

you had better have some decent examples, I personally find the bokeh from the sigma 50mm f/1.4 to be smeared and uninteresting.

This thread is useless without pics, so I'll post some examples from my 50mm f/1.2

this is what I call good bokeh rendering:



ISO 100 1/250th @ f/1.2

And good handling of Micro-contrast while providing High resolution.


ISO 100 1/8s @ f/11
