BillGarrett: Interesting new lens. IQ would need to be amazing, though, for me to give up my Sigma 10-20mm AF zoom.
Just compare the Sigma 10-20 to the Samyang 14/2.8 & 16/2.0 and this one is supposed to be even better.
AcerAntec: Grmf... 'Hope the Wizards at Magic Lantern's will increment this in their next release, to make Dual pixel, continuous focusing available for my 5D MkII. Et voilà.

Kurnia Lim: Can I use T-stop lens for just photo not video?
Joe Ogiba: Sony Professional Cameras S35 ? Is that the E mount ?
S35 is a sensor / film frame size, a bit larger than APS-C variants and unrelated to lens mount.
sportyaccordy: You know, on the outset these sound like great lenses, and I'm sure they are. But I think I will pass. The 16 2.0 for example sounds FAST. But on APS-C it's equivalent to 24 3.2 35mm. Meanwhile, I can get a Lens Turbo and an old 24 2.8, which would translate to a 16 1.8, for less money. A lowly 50 1.8 becomes a 33 1.2. Etc. etc. Plus I would be getting 2 lenses in 1 with each lens. Not saying these lenses are worthless or that the speed booster combos would be a match in IQ, but for me right now, ehhh. I mean a 24 2.0 an 50 1.4-1.8 would cover the span of a standard zoom with max apertures reaching 1.0 depending on the combo. Plus it's all MF anyway.
An old old 24 2.8 + a focal reducer (yet another glass element) will be inferior to a top echelon modern 16mm F2.0 lens, especially wide open and for off center qualities.
D1N0: of course it is only t3.3/4.4 equivalent ;)
And I bet your comment is based upon thorough light transmission testing vs other F2.0 / T 2.2 lenses :)
Digital Suicide: 90% shots it will be set to infinity. So MF shouldn't a problem.
It's way better to set the distance at 1-3m rather than infinity as with whatever F number other than fully open you'll get DoF reaching infinity anyway.
Chop lens and AF, add a popular lens mount (*), peaking feature and and HDMI connector for an external display and it'll sell nicely as a specialized sensor + mount body for demanding pros and enthusiasts.
* Ideally one of the short flange distance mirrorless mounts, 2nd best EOS mount.
