How about a razor sharp set of f/5.6 primes that have a large enough working DOF that you'll never know that the AF has randomly whiffed? :p

Most modern lenses can be f/5.6 or even f/8 ;) I remember f/8 lenses with no autofocus at all, in fact, no focus at all.

Imagine a focus free lens.

I am hoping to see a 60mm Macro Art with weather sealing and IF or update to 180mm Macro with Weather sealing.

F/8 and be there, as they used to say.

Most disposable cameras are still fixed-focus, as were many early smartphone cameras (the latter, of course, relying on the tiny absolute aperture size). The first iPhone to get autofocus was the 3GS, for example.
 
They announce a new lens with no hint as to what it will be? Given their penchant for originality, it is hard to say what they are coming up with. My dream lens would be an affordable 500 f5.6 with same build quality and sharpness as a 500 f4, but at half the price and weight.

Half the price and AF equal to the 135 Art, and I'll buy one.

I really want to make a DXO-like scoring site for AF hit rate. Something comprehensive with a battery of standardized tests of lenses on all bodies from the last 5 years.

We collectively believe the Art Prime AF situation to be:

20 = too wide to care, AF is pretty reliable
24 = AF is pretty reliable
35 = a hot, hot mess; non-dock-correctible spontaneous misses happen
50 = a hot, hot mess; non-dock-correctible spontaneous misses happen
85 = new more powerful AF setup, apparently much more consistent than the 35/50
135 = new more powerful AF setup, apparently much more consistent than the 35/50

...but I'd love to put a hit rate test and results database together. It would be stellar to see how a 135 Art does on my 5D3, for instance. It would also be nice to quantify just how bad/inconsistent the 35 Art is when shot wider than f/2.8 (hypothesis = not so good).

I don't have the time or budget to do this, mind you -- but it would be sweet if someone did. :D

No reliable AF = no deal. That's essentially the same as Zeiss making MF lenses (at least while we're waiting for the miracle mirrorless).

FoCal can theoretically provide you such numbers. The 85 art consistency is quite good.

I've had such a long running issues with Sigma's unreliable AF, I switched from the brand years ago and now for me it's Canon L's all the way.
Having said that...the Canon mkI ef 35mm f1.4L AF was pretty reliable until you are in very low light. The it was dispotic and next to useless. I could get a lock on my 24-70L in light levels my 35L could only dream of. The ef 50mm f1.2 L wasn't much better. Both copies I had were consistently unreliable AF in anything other than bright light...which is bizarre considering it's intended usage.

That was my first thought as well. I remember an article from 2016 stating they were going to replace the current 70-200 'in the next comming years'. If they announce now, then I assume the lens will be available somewhere 2Q18 or 3Q18. I expect it will be near as good as the Canon counterpart for 65-70% of the price (say €1.400 - €1.500).

I love my Canon 70-200mm f/2.8 L IS II, but the rear zoomring is bothering me. The fact that the tripod support is just at that zoom ring makes it harder to zoom while keeping the lens stable. All my other lenses have a front zoomring. You can simply put the tripod support on the base of your hand and zoom with easy. If the zoom ring for a new Sigma 70-200 Sport is in the front and image quality is (near) as good as the Canon, I might just sell it and get the Sigma instead. I already have several of the Sigma Global Vision line lenses and the USB dock, so if IQ is good, this one would fit in perfectly.

What if the AF accuracy is also 65-70% of Canon's? ;)

If you own few Sigma Global lens and USB dock, then you would be aware that a Sigma zoom requires calibration at 16 points. If you use FoCal for a proper AFMA calibration, then it takes 32 FoCal runs in total at very minimum to to get initial reading at every calibration point a, disconnect lens from camera at least 16 times, set AFMA value in lens via USB dock, rerun FoCal to confirm the adjustment value was adequate.
Be prepared for at least 3 hours of ultimate fun and 1200-1500 shots taken while you at it.
Better even, you would have to repeat this process in about 6-12 months as AFMA values would drift in lens a bit with time.
It takes faster to calibrate 4 Sigma primes than a single zoom.
Sigma service centre won’t calibrate your lens at 16 points. They calibrate at 4 points and at x60 the focal length instead.
Regarding Canon 70-200 zoom ring located over tripod mount:
If you use the lens on tripod, it is not s problem. For handholding situationsIt takes 30 seconds to remove the collar.
It makes the lens much more comfortable to use. Turning tripod ring by around 120 degree is another option.

Jopa,

Good thinking. It may hit the rock bottom ( FoCal was unable to identify AFMA settings for your lens, return AFMA value set in lens to 0 and start again) on your next camera. Compatibility is not guaranteed. The statement that Sigma will provide a fix via firmware is false. There are ongoing issues with Art lenses that cannot be fixed.

Apart from AF accuracy, for Sigma Global lenses , all in camera image corrections must be switched off. If your requirement is a rapid OOC images delivery and you shoot jpegs then it may be an issue.

All in all, the notion of owning a sharp but unsupported by Canon lens, leads to unpredictable outcomes.
Personally, I had enough. I run and gun with Canon trinity of latest and greatest lenses and that puts a smile on my face each time I am zooming in on an image for critical focus evaluation.

Sure, yet all that effort does nothing for AF consistency, the real terror with Sigma glass. I went through great pains to use the USB dock during a 35 Art rental on my 5D3, got everything dialed in, but when shooting wider than f/2.8, the AF simply 'whiffed' inconsistently -- a complete miss either front or back -- at an alarmingly high rate.

TL/DR: A dock is great for your run of the mill back- or front-focusing, but it's useless when the AF randomly and completely lays an egg.

Correct. Worse even on your next and unreleased camera body. It may hit the rock bottom. As per my previous post on this page.

I'm hoping for a 50-85 f2 to compliment their 24-35 f2 for the ultimate wedding combo - faster than typical f2.8 zooms but more flexible than a 2-prime combo like 35mm and 85mm.
