If it's $1300 I likely will not buy it.  In the rare circumstance in which my 35mm Art is just too wide, I'll settle for my Canon 50mm f/1.4.  This may be mostly psychological but at $1100 I might just go for the 50mm Art.

Coming in at 1/3 the price of the Otus but with similar build quality, nearly-as-good optics and AF?  If all that can be said, I think Sigma will get quite a few takers even at this price.

The only difference is that the Otus is cool and can be shown off, the Sigma can't. This is why I think the price will be < 1000 USD.

I show most people the 35mm 1.4 Art and they'd die to own one. I'd rather go "look at my amazing lens, it cost me $1300 and I can do everything I want with it" than "Look at my amazing lens. It cost me $4500 and doesn't autofocus, so I can't use it for work. But my wallet is sure big"

Shown off to who, if you don't mind my asking?  It's such an exotic piece of tech that only other photogs would know what it is. 

With that same money, you can you get a second FF body along with this new Sigma 50...  Just saying.

I'm going to go out on a limb and say that Zeiss is counting on a few of the Ferrari-driving enthusiasts to pick up an Otus and say "hey, look at my pricey new toy", but more likely they are aiming to impress the best pros with the best tool in that focal length.

I noticed it while hand holding and using AI servo to lock focus. I have pretty steady hands, but I really hope that I'm just an idiot and it was because of the hand holding. I haven't tested it using a tripod yet but I will tonight. I was hand holding because I was doing some AF testing that involved movement. When I noticed the inconsistency I did the tests hand holding still but not moving the camera or the subject. I'm still hoping it was just shaky hands! But I felt like it would be more honest to write it, I was pretty vocal about my 35 being so great...

AI servo isn't designed to lock focus, it tries to achieve focus quickly and constantly refocus to track action at the cost of accuracy. You shouldn't expect AI servo to get accurate focus in low light, switch to one shot in low light situations, it's a night and day difference in those situations. :)

If that's how you have set up your Servo you're doing it wrong. I can keep servo on a target for half an hour if I want to and move a little back and forth, or stay still and it's always locked right. I never ever use One Shot.

I do the same with my AI S, it even stayed on target when I jumped at it and pressed the shutter mid-air!

Wow that's bad. I admit I didn't always choose the perfect (most contrasty) targets, but this from a lens that manages to AF in low light mid-air no problem.
The previous were all on a tripod. I just tried handheld (AI S), 8/11 (72.7%) in the dim room. That's the exact same result as with the tripod (with AI F), and I used different targets and the camera was in a different place.

It's never been that bad before, it's been reliable even in lower light levels. Now I'm a little worried :( How can the AF just suddenly get so much worse? Or did I just try to focus on impossible things? What really gets me is that it nailed all the white-on-white targets. That doesn't even make sense (unless it nailed them because they were the only things emitting enough light?)
All tests were done wide-open. I was hoping it would just be a problem wide-open but I tried AFing on my black lens cap on bubble wrap on white in the dim room and it front focused :( even though i had the middle point at the edge of the cap so there must have been plenty contrast.
I should note that both rooms have like the dimmest lighting ever. Many normal homes are probably a lot brighter. This lens still focuses perfectly in bright light. It only seems to have problems in low light.

I love you Sigma 35... Please don't give up, stay with me...

edit: I talked it over with Viggo and realized that's not bad results at all because the light I tested in is actually terrible! (I just never realize how terrible because I'm used to it (really need to replace the light bulbs!))
In bright light it works great so I was just worrying for nothing :)

Or, if you make that second FF body a Sony A7/A7r, you could get the Zeiss/Sony 55mm 1.8, which probably makes photos that are indistinguishable from the Otus 99% of the time, and has AF (and, at present, is $200 off - i.e. $799 - if you buy it with an A7/A7r).  Come to that, the Zeiss/Sony on a 7R could well create better images than the Sigma, no matter how good it is, or even the Otus would on any current Canon sensor (leaving aside such questions as whether you need to track fast action).  Interesting times....

As is normal with internet experts who have become popular via links, clicks, likes, and linked advertising, he makes several basic errors that are just noise, this, for me, means he loses any credibility.

First, if the lens is projecting a circle then a lens hood needs to be a circle, but if we are using a rectangular section of the projection, as we do in photography, then the petal hood is correct for primes, or a rectangle.

Second, more glass equals bigger T Stop, unless your glass has exceptionally higher transmission characteristics than your comparison. Though the loss is small, the more glass light goes through the less less light comes out the right end, that doesn't mean the Sigma is not an f1.4 but his use of T stop and glass is entirely inappropriate.

He is just repeating memes he doesn't understand and using popular terms in irrelevant contexts, which kinda makes the video an annoyance to me.

This is simply silly! The Zeiss Otus is a lens like no other and the consumer group you refer to would never bother to use something that requires that much attention to detail to have any use of it at all.

All this comparison between an unreleased Sigma and the Otus has no meaning. They are built for totally different applications and use. The Sigma will Never compete with the Otus and the Otus will Never compete with the Sigma. Just like a Bentley does not compete with a Ford and a Ford never competes with a Bentley.

I have the Sigma 35/1.4 Art and based on the images we have seen of the 50/1.4 Art, the build quality can be expected to be the same. And it is a very fine lens. But compared to the Otus, the Sigma is plastic! The production tolerances, glass quality, mechanical quality, focusing mechanism (manual as it is) etc. is in a totally different league. It is a very long way from having a great design to produce stable, maximum performance from that design.

Yes, I´m sure that in certain cases the Sigma will produce equal IQ to the Otus and in lots of shooting situations I would much rather have the Sigma than the Otus. But looking at the sum of quality differences it is not difficult to understand why the Zeiss is a much more expensive lens.

And for the record, I have not received a single comment about the Otus other than a raised eyebrow why I bother to use i MF lens in these AF times. And I will most likely also buy the Sigma 50/1.4 Art, because it would fill a totally different need.

Let me rephrase: Zeiss lenses are prestigious items, Sigma lenses are not.

Do you think everyone who buys Leica couldn't be happy with a Canon or Nikon?
Did you notice manufacturers try to differentiate their premium products also visually? Canon has red rings and white lenses, Nikon has gold rings, etc.
If you buy a Rebel, the strap says Canon EOS. If you buy a 5D3 the strap says Canon EOS 5D Mark III.

I wasn't insinuating that the Otus is all about appearance; I'm saying that people are reluctant to spend too much money on items that don't give them gratification at various levels besides performance. Vanity is an important motivational component behind expensive purchases. This happens at a parallel level with respect to performance and is not limited to photography. Sometimes it merges with performance in the desire to own the latest & greatest.

Sure the Zeiss is nice. If it is even sturdier than the Sigma, that is fine, but what is the point of added toughness (beyond a certain point) in a lens that is so expensive most people baby it, and will never, ever subject it to abuse?  It isn't even weather sealed anyway.

I imagine that if most Otus owners got a cosmetic scratch on the barrel they would be sick to their stomachs even if the functionality was unimpaired due to the aforementioned toughness.  If you could make a lens out of the same stuff Wolverine's claws are made, and charged $50,000 for it would one sell the Otus and pick one up because it is indestructible?
