GH2 75mm Olympus vs. 85mm Rokionon

[Psynema]

I know the 10mm difference and Af vs. MF etc. and a stop slower, but can someone chime in on IQ? Is there really a reason to get the 75mm if you're happy with the 1.4 Rok? Can't find side by sides at 1.8.

The main advantages of the Olympus 75mm f/1.8 lens...

1- Autofocus
2- Maximum sharpness wide-open
3- Smaller size and weight

I just googled it, I didn't realize the Rokinon 85mm came in a micro 4/3 mount. 85mm 1.4 for $299? That's a pretty awesome deal. The reviews mention it's a little soft wide open at 1.4, but I wonder if that goes away at 1.8.

If anyone in Denver has a Rokinon 85mm I'd be up for doing some side by side test shots.

I'm aware of that, I just need side by sides or someone who's done both. Wide open is unfair since it's a stop slower.

It's actually 2/3 stop slower, but I suspect that it will easily out-resolve any other lens in it's focal length range at the same F-stop.

I have been thinking of selling my Zeiss ZF 85mm f/1.4 and replacing it with this new Olympus lens. ( I would prefer a black finish and it sounds like this will arrive later this year )

I'd also like to see side-by-side comparisons. I have the Rokinon 85mm 1.4, and love it, though I imagine the Olympus is likely better. At three times the price, it should be!

Probably goes to the build and AF though. Both at 1.8 is the fairest IQ comparison. Hate the phrase "better wide open" when the lenses have different max apertures.
