Wow, thats great. I must say I am surprised at the Rokinon. I was of course expecting the SSC to win out in the bokeh dept, which it did (in my humble opinion )

The Rokinon (Samyang) 85/1.4 does at 85mm what the Sigmalux does at 50mm.
At 100%, we can also get a good idea how they all resolve, although I have to say that I only focus bracketed 3 shots for each lens, so focus error could certainly play a role. I don't think there's too much error, but it is certainly possible.
That's it! I'm buying that damn Rokinion for my a900. At just over $200 after discounts, it's hard to go wrong seeing your tests. I will be sure to post some results when it arrives.

Wow, that Rokinon is a beast. IMO, it's the equal of the 85/1.2 in resolution, and I actually think it's a little better in the bokeh department.
Another test out there shows it to be at least as sharp as the Summilux 80/1.4 (wide open) and with much smoother bokeh. Here's the link http://forum.getdpi.com/forum/showthread.php?t=8293 Despite the focus variation in the test, it is pretty easy to see how the Rokinon performs against a lens that is worth 10x as much money.
I am very much anticipating the Samyang (Rokinon, etc.) 35/1.2 Aspherical

Looking at the last six images I see some slight extra cyan/green in the skin tones with the FD. With the final group at f2 I think her head is slightly more in profile with the Rokinon and the EF/1.8, so the cap looks more detailed and in focus than the FD shot.
But they are all very similar which surprises me. I am quite impressed with the Rokinon here. What is also noticeable is how strong the EF lens is. The EF looses some bokeh value by not being able to go beyond f1.8, but its color and detail look really good. It definitely holds its own at f2.
What would be interesting is to add a European 85 into the test.
The test of the Samyang 85 at letsgodigital found it superior wide open and up to about one or two stops down but mentioned that it never really achieves the absolute resolution of other 85's when it is stopped down further. Perhaps it was just their sample? Paul, can you confirm this finding with your sample?
I'd love to see any 28-35mm f/1.4 prime that equals Sigmalux or Rokinon 85/1.4. It'd complete my Rokkor like a charm on the XSi... Those two and a WA (Vivitar 17? Tamron 17? Zuiko 21?) would be a 'cheap alt trinity'...
Now, you've done it, I've been close to pulling the trigger on this for a few weeks and now i have.
What else does Samyang have up it's sleeve? I've heard of the 14/2.8 and 35/1.2( 35/1.4 for those who don't shoot Canon). Dare we dream of a high performance 180/2 for $1500?

The EF's bokeh is just plain bad compared to these other two, IMO. Look at the f2 bokeh samples again. The EF just doesn't have a chance. Unless, of course, you like the cat's eye effect. The fact that the EF shows this effect so stongly in comparison to the others is due in large part to the size of its rear element. Yes, that's right, it is bigger than either of the others. The EF's rear element is 35.5mm across, wheres the Rokinon and FD 1.2 are both 33mm. This size difference (especially in relation to the size of the rest of the lens) directly effects the "optical vignetting" which causes the cat's eye effect (see http://toothwalker.org/optics/vignetting.html).

Sure, I'll do some stopped-down testing as well, if I have time. I have to admit that I'd never use any of these lenses stopped down past f4, but it would be interesting.
I do know that the Rokinon is not so shit hot at infinity. Again, a moot point to me but may be important to some.
