Nifty, but given the size of the front element, I would prefer a 50mm f0.5

Now that would be awe inspiring.

Awesome. My favorite focal range runs 105-135 for portraits. I have 8 lenses in that range and love them all. This thing, though, is a beast. A trip to the local camera shop is in order upon release for a look at it. Sigma has never excited me, but this might do it. Can't wait to see posts from buyers.

If I ever bought this lens, I'd then also have to get a cat.  ;)

Very niche lens - I wonder who it is for.

Portraiture.  (How on earth was that your third guess?)

Only if you don’t mind having just one eye in focus. Just me, but this lens screams - just because you can build it doesn’t mean you should build it.

Sure, similarly the 200mm f/2L IS isn't for everyone.  But it's gold for some folks because those are the sorts of images they want to make. 

This is no exception to me, and if bokeh/isolation is your jam, this new Sigma is probably the 135 f/2L II you don't have the patience to wait for.

While this lens is - as all Art Lenses - of superb IQ I doubt that it is useful for my shooting "style": I like to be unbound.

A camera/lens combo mustn't go into the way while taking photographs. A 1.6 kg lens with 115x130mm size (on a 200D) is a BRICK. Loosing one f-stop and some IQ the EF f/2 100mm with its tiny size and weight (compared to the Sigma) lets me see this lens as the superior lens for MY requirements (as non-professional).

If the EF f/1.4 85mm IS had 1:4 maximum reproduction ratio it were the perfect lens for me: high max aperture combined with image stabilization (that I like to see in high aperture lenses designed for low light) + moderate weight/size again compared to the sigma.

But all in all Sigma is providing great options for those who like or need it and I would like to see more lens options from Canon with their mix of specs: very high but not superior IQ, small footprint, IS in high aperture lenses etc.
Most used tools: EOS 200D + EF-S 60mm + EF 100mm Macro + EF f/2.0 100  + 4.0 / 70-200 IS

it would be wide field deep sky stuff, that lens would be great for the likes of orion or the antares region particularly on a crop body where you can get tighter framing on bigger objects while being able to shoot at 1.4

for example i used my 24-70II at 70mm on a modified 760D for this just last weekend

Antares, Rho Ophiuchi and Blue Horsehead by Tony, on Flickr

i quite regularly use my 135 1.8 for dso as well

Great for those who want this. I prefer 135mm f1.8

Digital Vignetting gets in the way.
If you try to send light onto a digital sensor from too extreme of an angle the light gets blocked by all the layers of circuits and stuff before it hits the actual photoreceptors.
Backlit sensors help (theoretically at least, I don’t think I’ve seen a direct comparison), but in general most of the extra light wider than f1.4 never makes it to the pixels.

Personally, I like to hand hold my camera when doing portraits, and I would think that this lens is just too heavy to hand hold for long periods of time.
I doubt one will find its way into one of my camera bags.
You can get used to handhold such lens pretty easy. I was using 200/2 on monopod since day I acquired it, but today I use it hand held even on several hours shooting.

Precisely. 105mm is definitely in the "wideangle" (or wide field as they say) range for DSO astrophotography. It's much shorter than your average telescope.

Careful what you wish for.  Canon's two f/1.2L primes and the new 85 f/1.4L IS have the mirrorbox clipping phenomenon where you get D-shaped bokeh that -- once seen -- you can't unsee it in any other future pictures.

The presumption is that the wide open aperture of such a lens will be so enormous that the mirrorbox behind it will serve as an unavoidable 'bokeh template' like you see enthusiasts use to deliberately make background lighting turn into shapes (stars, hearts, whatever).

If this is a minor nuisance on a 50mm f/1.2, imagine how jarring the f/0.5 output would look.  You'd have breathtaking isolation, but the bokeh would look like blurry/boxy 1980s video game space invaders.  And I'm not even sure if FF mirrorless would solve this as even without a mirror in the mix, something in the mount/internals/etc. would likely be in frame for such a comically large aperture.

It's very simple -- you covet bokeh/isolation enough to carry this, or you don't.  It's not too heavy if that's the output you are gunning for. 

Also:  this Sigma is only a shade heavier (~100-150g) than the 70-200 f/2.8L IS II everyone and their mother carries around all day at events and photo sessions.  It's not a Sigma 200-500 2.8 or anything!

I think it's a bigger pain to have to pack this in your bag as it clearly won't fit in most conventional ~ 3.5" chambers in a camera bag.

At f/1.4 and outdoors, I suspect there will be a load of ND filters sold with this.  ;)

Very niche lens - I wonder who it is for. Wouldn't astro photographers want a wider angle? I had the Sigma 85 f1.4 EX for a few years and it was a nice lens, but too niche to carry most of the time so I finally traded it in. One thing about the 85, though, it was very handholdable. If this is heavier than a 70-200 2.8 I have a hard time understanding the appeal. It's not telephoto enough to be a wildlife lens. Maybe if you are a wedding and/or portrait shooter and you just want that little extra blur (to eliminate busy backgrounds on city streets, etc).

I have the Sigma 85mm f1.4 art (which is very different than the EX).  I also have the Canon 200mm f2, which is my favorite lens (I've got a S____ ton of Canon glass).  I'm not a pro, just a guy with a wife that understands.

The Canon 200mm is $6000, the Sigma 85mm is $1200.

I fricking love the Canon 200mm, it's by far my favorite lens and I've got the 600mm f4 II, I've got the 16-35mm III, I've got around $40K invested in Canon glass.  The 200mm is the one lens that if I dropped it I would buy another one the next day, it's that good.

In my opinion, the Sigma is 80% as good as the Canon.  Much better bang for the buck.  Here are some shitty pictures I took when I was drunk at a party, that's all the Sigma.  It's a great lens, it is becoming my second favorite lens:

Sigma has really stepped up their game.  I'm not sure why you would want the 105 over the 85, well it will flatter your nose a bit more, but if it is like the 85mm art, you can't go wrong with that lens.  These Sigma lenses are not like the shitty couldn't focus crappy quality Sigmas of 20 years ago, these are L quality glass and the auto focus works.  Kudos to Sigma.

I've seen 5 of your images and 2 are front focused => I don't think that Sigma AF is dramatically improved on fast primes. (I like the Sigma - I own 85/1.4 EX, 50A, 120-300S, but none of the lenses are any close AF consistency to Canon glass.)
105 is better than 85 any time you can not get closer to your subject and blurred background will be a lot smoother and I hope there will not be any fringing (all 85/1.x - Canon, NIkon, Sigma, Sony exhibits) = I hope the IQ will be more like 135mm
