GH3 Olympus 4/3 mount vs Micro 4/3 mount?

Four Thirds lens mounts are different to m43 (sensor size is the same). There are adapters, particularly from Olympus but not all features of the 43 lens may work. In this case, since the lens is manual that's not an issue, although I can't really make out if there is an aperture ring.
 
Looks identical to Samyang's 85/1.4. They already sell under the brand names Vivitar, Falcon, Rokinon, Walimex, Bower, Opteka, Polar and Pro-Optic, so why not Bell & Howell.

Don't know if there's a dumb 4/3>m4/3 adapter & I'd be a bit hesitant to test the smart versions by Panasonic or Olympus.
 
As others noted it's a fully manual lens, but you'll still need an adapter to use it on m43. I'd get the Nikon mount lens for the same price and an adapter because it can be used on other mounts more easily.

Another thing to note is Samyang's lenses with a Canon mount have a focus ring that rotates the same direction as Cine, Canon, Lumix, Leica, Contax & others, while their Nikon mount lenses turn the opposite direction.

I agree. Even though I own a dumb 4/3 to m4/3 adapter, if you can buy a Nikon or Canon EF mount version of the lens for the same price, those would be more adaptable to other cameras, and the corresponding m4/3 adapter you would buy to fit it to your GH3 would be more useful.

Gotcha. Thanks for all the responses. All my current lenses are Micro 4/3 mount, and I don't really like to use adapters. Too many moving parts between the camera and the lens for my taste.
 
I had the Rokinon "cine" version of this lens in Nikon F mount. The adapter for m4/3 was fairly inexpensive (under $20 from an amazon vendor) and had no moving parts besides the Nikon F "latch/lock" system. It all worked just fine but I only kept it a month and made myself "afford" the Olympus 75mm f1.8, a far,far better lens overall.
