I've heard from a number of sources that the sigma 35's bokeh is blah.. and not as impressive as the Canon option.

I find the bokeh in the Sigma 85mm not as pleasing as the same, shot with my Canon 85mm f1.2L II.  Performance wise, the Sigma smokes the Canon 85 but that is not the subject here. 


The good news for bokeh is that the 50 is basically a modified 35, so it should be a slightly better longer focal length version of that lens (very slightly sharper on average, less distortion, same bokeh in other words).

I actually went the opposite way with the 85mm Sigma though, the bokeh of the Sigma has a nice pop to it, with beautiful interesting OOF highlights, the Canon's is very very flat, which can be a good thing if that's what you like, but I liked the Sigma 85's better.

 :P Just swallowed my big grains of salt.

I'm calling it here. I think those tests are fake! If you can get your hands on the Otus AND this Sigma lens that no one else seems to be able to get a hold of, I would think the the test shots would have been more professional. I have seen better fake iPhone 6 pictures!

yes, we need to see some real tests but I think Sigma's likely got a lens they can be proud of.

... as I continue to cuss the inconsistent AF of a new, but past warranty EF 50/1.4

As much as I love my 2 ART lenses I just don't use the 50 I already have that much. Not due to the quality or lack of wit the 1.4 but the FL. I truly hope they have a great lens at a decent price but I think I'll be passing no matter what it comes out at.

One word: Impressed.

From this initial testing, this can be a real competitor to the Zeiss Otus. If I had to replace my Zeiss 50mm with something else, I would consider the Zeiss 50mm f2, then the Sigma or Zeiss Otus. But if the Sigma is that good???

I have the Sigma Art 35, and I honestly love it.  Sharp, bright, and lovely bokeh and colors.  I do believe this lens will be, if not totally equal to the $4k+ Zeiss lens in sharpness, etc., then at least 95% there, based on the fact Sigma seems to be vouching the lens will be even better than the 35. 

I also think the only reason Zeiss does not put AF on their nice lenses, which even the cheap-o kit lenses everyone else makes do include, is that they only have the ability to make so-so AF.  They only put it on a few cheap-o Sony lenses, and it is only cheap-o AF.  They make MF lenses with glass that works like a decent precision microscope, but they simply have nothing special to offer in the area of AF (OR I.S.), so they shy away from trying, so they don't catch the flak for slow/inaccurate/mediocre AF that would tarnish the reputation of their optics.

I also had both, and I think that the difference is often not a big deal, but I like the 35 L better, it seems smoother.

I have a feeling choosing between this and the Fuji 56f1.2 isn't going to be much of a contest.

Aglet...Thanks for the link to IR ...THAT was VERY informative and really helped me to understand what I am looking at with these rather primitive Chinese test images.   If these are legitament test images, even though they we shot on different camera bodies...the tests are still telling a story, and since it is the only info we have at this point it appears that Sigma has a real winner on its hands here.  I really like the way the story of this lens is developing! Can't wait to find out more.

I'm in the same boat as you - being a bit newer to photography I figured/hoped that the 'old' problems with that lens would have been addressed in the intervening years.  19 months out and I have a lens that is pretty inconsistent past about 10 feet away.   I'm not planning on sending it in for repair and spending nearly half the price of a new one for the privilege.   I have a 40mm I'm quite pleased with.  And I really only use the 50mm occasionally, not regularly.

If you've heard that then it probably originally came from me, or from the source I originally used.

What happened is that the first outside photographer that got to sample the 35mm f/1.4, was somewhat amateurish and used very weird clarity enhancing technique on his photos (no doubt to make the incredibly sharp lens look even sharper). This made the bokeh transitions look seriously bad, and because Sigma published their photos as the first official samples I and a few other people immediately pointed this out that the bokeh was defective. This was not the case and ever since everyone has praised the bokeh of this lens.

The 35 ART's bokeh is very similar to the 50mm f/1.2L, contrasty yet buttery. The 35L has bokeh that's closer to the 85 L II, which is very flat on the other hand.

The main problems with the Sigma are distortion and purple fringing.

<ironic>I think everyone can beat the OTUS or Sigma lenses with a Canon Lense, even the 50mm f1.8. Just patch your lense, today. It's soooooo easy</ironic>  ;)

Hi wicked, your right, Bokeh seems Ok, but I think you had too many of these BEFORE taking the shot, the Glass is leaning to the left, you needed to stand with your left foot on a box of matches so you could have the beer level, works for me.
