I'm aware that the Rokinon is manual focus only but I'm curious if any one in this forum might share their opinions on both or either of these FE's.
Thanks!

Autofocus is a waste of time with a fisheye lens - set to f8 and just behind infinity on the focus ring and everything from about 2ft to infinity will be in focus. Optically the rokinon is as good (maybe better) as the panasonic - save that money for another nice prime!

Thanks to all for posting, and thank you wjiang for the link! The Rokinon is the better lens and a bargain too. You rarely get those two qualities together!

If you're shooting close focus and in low light, I think having AF for this type of lens has it's uses.

Some call it the arm pit of NYC.
I shoot with a 12mm f/5.6 heliar on a Leica M body. When I first got the lens a few years ago, I was a little hesitant because it has no rangefinder coupling at all. This means I cannot focus it using the rangefinder mechanism.. I can only "guess" it.

After spending the day shooting NYC with only the 12mm in hand, I discovered that I had nothing to worry about. The DOF is so deep that you can pretty much shoot at the hip. The Heliar has two presets/notches on the focus ring to make zone focusing easy without even looking at it. Even in low light, the wide focal length makes it easy to hold longer exposures.... For some older slower focusing cameras, I would surmise that zone focusing would actually be faster.

I don't have either of these lenses being discussed but I assure you AF shouldn't be a deciding factor... just like many have already posted.

The Samyang/Roki fisheye is an absolute gem!

I love mine...manual focus is no issue at all (I set it to just this side of infinity and forget about it), and the manual aperture ring is actually fun to use.

Image quality is superb. I'm pretty sure it outresolves most (all?) of my other lenses...it's just ridiculously sharp. Contrast and colours are great too, vignetting has never bothered me (which is saying something with a fisheye!) and you can really play around with the distortion...put your subject along either the horizontal or vertical axis and the distortions are very manageable!

I bought it as a cheap toy to have fun with, but it's become an integral and serious part of my kit!
