I have one too. It is truly an excellent lens despite quite a bit of purple fringing and aberrations and heavy breathing. Exceptional lens. However, I 'm actually thinking of selling mine. I got it cause my two other main lenses, the 20mm 1.7 and the nikkor 50mm 1.2 AI-S in FF terms are 40mm and 100mm, leaving a big gap in between, which the 35mm covers as it is equivalent to 70mm. But, for portraits and close ups, I prefer the nikkor 50mm, for handheld and "wides", the 20mm is obviously better, so I haven't really got much use from the 35mm. I think if you shoot in confined spaces like small houses+apartments, and do interviews and stuff, it's really usefull, but for most of the stuff I do, I can move with the 50mm a bit further back and get the 70mm equivalent, not that big of a deal for me. But I'm not too worried as it's a good investment and I bet is easy to resell, so I'll think about it a bit more, it's just that I'm short on cash and haven't got proper income, and I'd rather have another couple lights. :(

The Rockinon rocks!!! I got the lens few weeks ago. When I got the lens, I thought it's really heavy and big, because I used to use Nikon 35mm 1.8G for 35mm FOV. Now I want to sell my all other prime lenses to get all Samyang.

+1. They gotta rename the brand to Rockinon. Or Rocky!!!

I thought about selling my FD, AI-s, Vivitar, Hexanon... but those are fun "small" lenses for my personal work. Keep'em all.

Samyang is internal focus. A big plus when using a matte box with 4x4 filters.

GH body + m43 pancakes for candid photo. GH body + big lenses for video. It took me more than a year to make up my mind.

I feel great about this purchase. YMMV.

I have this lens too, for a few months now. Nice for stills, but not usable for video; maybe only handheld.
Focusing makes the optical block inside wobble up and down. If you turn the focus ring clockwise, the image moves up, if you turn it ccw, the image moves down. The optics move about half a millimeter, but on a 24 inch screen, it's already almost a centimeter. Guess what it looks like on a 20 foot cinema screen...
I tried to swap it for a better one two times, but this is just a design flaw; the three lenses i've seen were identical. So, i've stopped using it.

No focus pulls on this baby.

I didn't see the up and down issue either.

BTW does it need a lens support?

It is a beast. But it sure looks great with Cinematics matte box. I bet some clients would be impressed by the look. Haha.

I am intrested this lens a lot. What adapter would work best with this? Nikon? Canon?

Re: Wobble:

I have the 35mm 1.4... And I am experiencing a wobble- however it has nothing to do with the optical block inside the lens- the whole GH2 is simply moving up and down .5mm or so when I use the Follow Focus (seriously small pulls). Any ideas regarding GH2 stabilization - especially for this lens (and other larger lenses?)

I am using a TrusMT FF + Shoulder Rig + Rails + Letus style quick release block.

Maybe its time to get a cage?

@alcomposer

Here's how I mount the Rokinon 35mm on my follow-focus shoulder rig - it's very stable:

@alcomposer

It looks like Chinese now make many adapters with such mount.
Pentax PK, Nikon F, etc

Thanks @LPowell!

Ill get one and report back here what it is like (I have a few gear reviews in the pipeline) I am a bit suspicious re the build quality- (would prefer a PL style) - but I may be surprised!
