[brad-man]

I wish they would put OS on these lenses. It sure would look sexy on my M5...

 

[Chaitanya]

Sigma is killing it.

 

[exquisitor]

Wow, this is unexpected! This focal region will be quite crowded in the Sigma line: 85/1.4, 105/1.4, 135/1.8.
It seems to be a non-macro lens. In this case there is also no distinction between all three.

 

[mb66energy]

While this and the 70 macro are interesting offers one point is open:
Like brad-man I ask myself: Do they have image stabilization? While for the 1.4 105 I think this is not the case a macro lens should have it to be an interesting offer.

My Opinion: I would prefer an updated EF 2.0 100 with IS, better LOCA correction, 1:4 close focus and only moderately increased size / weight. A 1.4 105 with tripod foot nearly not as flexible to use - I bet it has a mass of 1250 g.

 

[AE-1Burnham]

A perfect lens -- if it had OS!?!

Well, keep it up Sigma. Great options and wow, really filling the holes of Canikon! Thanks for that.

Happy shooting y'alls

 

[Besisika]

I wouldn't mind the weight as long as it has IS. I would be interested. I need IS in that focal length for that F-stop.

 

[aceflibble]

Nice. Just last week I was lamenting still using the 100/2 while Nikon has the 105/1.4.

I don't trust Sigma's AF, though—every single one I've owned, rented, or borrowed has had such horrifically inconsistent, vague AF that I've had to resort to just focusing manually—and they're not well-made for manual focus, either. All their lenses of this type lacking sealing, as well.

Fingers crossed they've had some kind of breakthrough in AF and they've stopped being stingey gits and have built a premium lens with an actual pro-quality focus ring and sealing. If they have, this is the most obvious, no-brainer, instant buy for me. (And hopefully they then put out a 28mm to match it.)

My Opinion: I would prefer an updated EF 2.0 100 with IS, better LOCA correction, 1:4 close focus and only moderately increased size / weight. A 1.4 105 with tripod foot nearly not as flexible to use - I bet it has a mass of 1250 g.

You don't get to throw in IS, let alone better-corrected glass, for only a 'moderate' increase in weight over the existing 100/2. That lens is extremely small and light to begin with; anything more up-to-date will always be much bigger than it. If you want closer focus too then you're looking at basically the existing 100mm L but with a wider aperture; exactly how light do you think that could be?

 

[MintChocs]

I can’t believe there is a huge market for such lenses. As said above 85,135 and now this. How do they make a profit on such small production runs? I would prefer lighter f2 versions with IS.

This Sigma 105 is going to be GIGANTIC. Too big for me. Like you, I'd be more interested in a 100mm f/2.0 with IS. Let's hope Canon makes that in the near future.

Tamron's 85mm f/1.8 with VC (IS) is about 700 grams. Heavy for an f/1.8, but not extreme. Perhaps a 100mm f/2.0 with IS could be about the same weight.

 

[funkboy]

Wow!

This is going to be amazing for portraits, concerts, weddings, etc. I'm a big low-light geek & this gets me hot.

Like lots of folks, my first reaction was "why no stabilization?"

but if you think about it:

• Adding IS to large-aperture lenses is *hard* & adds size & weight. Large glass elements are harder to stabilize as they need bigger motors etc.
• Cost. Sigma knows that no matter how good it is, there's a limited number of people willing to shell out much over a kilobuck for a "3rd party" lens. This'll certainly be more $$ than their 85mm f/1.4, which is already a grand at B&H.
• This sucker is going to be heavy, so that makes it easier to hold steady.
• Bragging rights. This is the only competition to Nikon's 105mm f/1.4
• I already own a Tamron 85mm f/1.8 VC; would I buy a Sigma 100mm f/1.8 OS? Probably not. Do I want a 105mm f/1.4? You bet I do.
• Super-luminous lenses like this are less needy of stabilization than smaller aperture zooms where it's harder to maintain a high shutter speed. You can "stabilize" a fast 100mm by setting auto-ISO to e.g. 1/125 min shutter speed, but there ain't no substitute for the "wow factor" of a full-frame f/1.4 lens.

 

[wtlloyd]

No IS? I'd think cost is the reason, first. A lens this fast will give very good shutter speeds at still-decent ISO, shot close to wide-open. Weight and cost, without IS, will be much more manageable. Bet they sell a bunch.

 

[IglooEater]

I wondered if some third party would release this, when Nikon released theirs a while back. It’s a way to get bokeh close to Canon’s 85mm 1.2, fits into a Nikon lens mount throat diameter. I’ve been told that their smaller mount makes some very specific lenses difficult, such as an 85mm 1.2

Edit:
I think it’s quite telling of the shift the market has taken over the last few years that nowadays when a fast prime is released that we even ask whether it has IS. Go back 10 years and there were no stabilized anythings 1.8 or faster.

 

[slclick]

If only it had stabilization, just kidding. It's been said right? I agree with fb, this will be an interesting lens. Can't wait to see image samples.

 

[vscd]

It's a perfect portraitlens, but no weathersealing - no buy.

I had quite a few raining-events on weddings or in location and I don't need another failure like on a 50mm 1.4 Art... seal it. 8) I went to Tamron in the meantime and got sealing+VC together with f1.8 which is working out very well.

 

[ahsanford]

Judging by the size of that front element relative of the mount, that is going to have one big filter diameter. 86mm? 95mm maybe?

Also, presuming this is real and happens soon, Sigma Art will have knocked out fast primes in all of the following FLs:

14
20
24
35
50
85
105
135

That represents almost the entire non-white L prime lineup -- including fringe-ier items like 20mm and 105mm -- knocked out in less than 6 years.

If you look closely at the lens name in the image in the original post (http://www.canonrumors.com/wp-content/uploads/2018/02/sigma105artnok.jpg), it says 105mm diameter.

 

[jolyonralph]

Would be great if someone came out with an equivalent of this lens with autofocus.


And yes, I know what the specs say, but this is a Sigma. If my sigma art 35 lens gets focus right 50% of the time then it's a really good day. Doesn't matter how great the optics are if the autofocus is junk.

The 35 and a few others used a much older AF motor and algorithm and the later models are quite impressive. Some rival 1st party such as the 85 and 135 not to mention the 24-35 as well for an older model with good AF (easier on wide , I know) It really is night and day.
