Seems as if Sigma doesn't want to get wet ... - Klaus - 02-26-2018

That approach is a little meh ...
It's really astounding that Sigma doesn't jump on the mirrorless wagon really.
The days that mirrorless cameras were exotics are long gone by now.

9 AF primes is "meh" to you? Feel free to kickstart your own design of AF lenses. Like Tamron, Tokina, Voigtländer, Laowa - whoopsy: No other brand comes up with new designed fast and affordable AF lenses? Don't they want to jump the Sony waggon? How come?

I'm sure you are aware that
- these are no dedicated mirrorless designs this just adding a spacer is a little cheap
- the AF motor is DSLR centric - works well with phase detection AF but crappy with contrast AF.
And whoopsy ... why can't Sigma do what Samyang can ... :-)

The AF - at least what Sigma claims - is changed to the needs of mirrorless. So it's a bit more than just a fixed spacer, but if I were Sigma I would go the same path: The lenses already are big, heavy and good. More distance to the sensor is a good thing in terms of corner vignetting, I think. Developing a new set of lenses, although there is no FF mirrorless from the big 2 would appear to me as economical bullshit, sorry. If samyang wants to dedicate themselves to Sony bodies, have fun - they already are new kid in town if it comes to AF lenses, so why not start with what it's available.
But Sigma's hesitation I understand fully.

This is rather disappointing in itself, and I would've said more fitting for slackers like Samyang, but even Samyang has started to work in the earnest.
I have no FE cameras to consider, and I'd hardly go for any of those to put on the NEX-3 that I happen to have - if anything, I'd rather get a Canon mount version to do double duty on an adapter.
I'm sure most users feel about the same.

FWIW, Sigma claims to have improved the algorithm - thus it's not about new AF hardware.

Indeed ;-)

I prefer to see the glass as half full and be happy of the possibility to mount the mighty ART 85/1.4, 105/1.4 & 135/1.8 with native high speed AF instead of with the slow MC-11 adapter.
As the size of the Sony Zeiss/GM 35/1.4, 50/1.4 & 85/1.4 is similar to the Sigmas, I'm not sure if a redesign from Sigma would be worth the efforts.
The case of the 14, 20 & 24mm is more disappointing but there are already many e-mount alternatives for wide angles.

That's probably the safest approach if you shoot static or slow moving objects.
In my experience, AF-C was not reliable past 3fps with the MC-11 adapter. I guess the protocol conversion introduces some lag in the communication between the camera and the lens.
For the e-mount lenses, Sigma claims to have licensed the protocol from Sony and that the lenses are compatible with high speed AF.
