The EF mount version won't have auto-aperture, since the EF mount has an electronic aperture coupling. It should have auto-aperture in F, K and alpha(?) mount since the aperture is coupled mechanically to the camera via a small lever.
Yes, I should have specified that it will be manual aperture with stop-down metering on the Canon mount. Other mounts is manual aperture, but the aperture is stopped down mechanically.
i can't actually see anything (picture not loading), but it would be useful to see a comparable shot from the other 35/1.4's. i've noticed significant loCA in shots from all accept the new nikon which i haven't seen enough shots from.
Although the text is in Polish language, on the following pages you can find test photos showing bokeh, sharpness, chromatic aberration, vignetting and distortion - at each aperture.
Here is a short summary of this test.
Advantages:
- decent sharpness in the range f/2.8–f/4.0; very good for f/8.0– f/11.
- well corrected chromatic aberrations and coma
- nice bokeh
- easy manual focusing
Weak points:
- poor sharpness in the range f/1.4–f/2.0
- heavy vignetting
- heavy distorsion
- big dimensions

Is this true? I thought that stop-down metering would be required. I don't think the camera has any way to control the aperture.
Urgh, stop down metering? I was hoping one of the small luxuries of a new EF mount lens would be that you would have the aperture controlled by the camera body. Was hoping for a nice manual focus 35mm lens at a decent price, but looks like I have to fork out for a Zeiss to get what I want.
Let's wait with the final conclusions for another review which should be posted soon by LensTip (http://www.lenstip.com/). I wonder if they confirm the results of first test.
Keep in mind that the above test was on a lower MP/ resolution Nikon D700. What happens on a current 20+MP body? IF the test is representative of the lens, things are going to look even worse.

the D3X-samples and d700-samples we have seen so far are not indicating that at all. I would wait for a more reputable test and samples from the crowd that will get it. It will not rival the nikkor 35 1.4 af-s in the center wide open resolution-test, but I suspect it will rival the new 35 1.4 ZF/ZE from zeiss though.

Your point is very valid and influences and relieves all withdrawal symptoms i might have had in regards to this lens.

the weird thing is that at 100% the d3x shots look sharper than the d700 shots at least @f/1.4.

Could be user error and the test is not representative of what the lens can do. The D700, in particular, is not really known for superb per pixel detail as, for instance, a classic Canon 5D is. Those shots do look particularly soft to me though.
I simply do not see anything "plenty sharp" taken at F2 or faster. It's alright but nothing special. Stopped down it looks fine but then I would not buy a large 1.4 lens and shoot it at F4-F8 all the time. I think this particular lens really needs to perform as well as the Samyang 85 1.4 between the critical f-stops of 1.4 - 2.8 and I'm just not seeing it yet myself. As you say though, the lens may prove to be better then what we are seeing once it finds itself in the hands of competent photographers.

Well, it looks like the new zeiss does from 1.4-2.8.. :P as said earlier, the only lens that really "wow"-s me in this range is the new nikkor 35 1.4.
