I just wanted to add my thoughts about this lens after about six months of using it all over the world. As far as the optics go, it pretty much crushes my old Canon 35 1.4. Autofocus accuracy is pretty good, and the general construction of the lens is almost "L" quality. That said, I have found one major problem with it. While in Bangkok covering the protests last week, the autofocus driver died numerous times. It was clearly connected to the humidity (which never got THAT bad, about 80% while I was there). I have been in contact with Sigma, and will update when I receive a resolution. Obviously, the Sigma isn't weather sealed, but if the lens can't handle a mildly hot and humid afternoon, I'm not sure if I can give it my trust anymore.

All of that said, unless you are working in weather extremes, buy it, it's a hell of a lens.

Seems there ought to be a DIY way of adding an o-ring at the camera mount.

If the Canon EF 35mm f/1.4L is weather sealed, I see no evidence of it.  I suppose it must be, though.

I'm curious if any of you have done astrophotography with this Sigma lens.  If so, is there much coma toward the borders, and if so, how far does it need to be closed down before that goes away?  I'm sure somebody has talked about this before, or perhaps over at lensrentals when they imatested it...but I forget.

The Canon EF 35 f/1.4 isn't officially "weather sealed."  That is a feature many are looking for in Mark II is released.  Regarding the Sigma, lenstip looked at coma:
http://www.lenstip.com/359.7-Lens_review-Sigma_A_35_mm_f_1.4_DG_HSM_Coma__astigmatism_and_bokeh.html

But I'd be interested if any one has used the Sigma for astrophotography.  I am on the fence about the Sigma.  Other than the Rokinon 14 mm f/2.8 UMC, it would be my first non-Canon lens.  Hearing about two different AF issues isn't helping move me off the fence.

Thanks very much for that link!  Looks like an incredible lens for astrophotography to me.  Even the best Zeiss are no better than that.

You should just buy the Sigma and attempt to make it have AF issues.  If it doesn't during the return period, then decide if you want to risk keeping it.

I personally would rather have a 28mm f/1.4, than either a 24 or a 35.  Apparently 28mm is the redheaded stepchild of modern lenses.  Nobody likes making one anymore.  Nikon had a great one in the past, from what I have read.

I have become convinced that you ppl with an eye and a feel could do that with whatever lens I put in your hands...

I like this shot,

Thanks!
Actually i took that shot in a rush in response to someone else posting a shot of a newer "stax" headphone. i thought, i use those, well, a much older version, but close enough for me.

so i posted here, then i went over to that thread where i asked people to find the fault in a shot and i see that you posted there also. then i got back to cutting pumpkins and thought, i bet that was sarcasm. if so, that would explain it, and that's a good one. nice..

Yes that was sarcasm... I did see the sleeping kid... but finding inconsistencies with the presentation v. the scene seemed the way to go...

The headphone shot comment was guenuine...

ok, gotta say wow.  not only about this lens but this focal length.  I have been spying the meta filter in lightroom and this lens has quickly become my most used lens.  Of course the quality is outstanding, but more to the point --- it's in the land of, wow been shooting for so long without a variety of lenses but now...just wondering how I could have lived without this focal length.  It's just so versatile...

I have to admit that I really love the outcome in the Rusko, and the Jessica & Steve shot. I'm no big fan though of the vignetting in the sky on the J&S kiss, but that is only my personal taste.
