The sensor in the m4/3 means that the Field of View is half that of the same lens mounted onto a 35mm full-frame.

Effectively:

35mm Samyang = 70mm on m4/3
24mm = 48mm on m4/3

Note, this applies even to the m4/3 lenses, so the Panasonic m4/3 20mm Pancake on a GH2 will have the equivalent FoV as a 40mm lens on a 35mm full-frame camera.

Other good thing in Samyang produced lenses is that they make good investment.

I can instantly use them on my Pentax, mount on m43 bodies.

And could mount on FF body is this become available.

So now since I have the Rokinon FE14M-C 14mm F2.8 Ultra Wide Lens I can say that YOU can't use any 77mm filter you like with this glass.

It's not a problem. I could've done more research myself ;-)

I love the 35mm one and can't wait for 24mm to come out. It looks very solid just like the 35mm one from the pictures you posted in the first post .

That's a great news. I'm in the market for good 4x4 nd filters.

@stonebat Yes, both the 35mm and 85mm Rokinons use internal focusing mechanisms and have fixed front lens barrels that neither extend nor rotate. The 24mm looks like it's built the same way as the 35mm, so I expect it uses internal focusing as well. The Nikon (and probably Pentax) versions of these lenses have focus rings that rotate in the same direction as Nikkor lenses, unlike Sigma's lenses, whose focus rings all rotate in the same direction as Lumix lenses, regardless of mount type.

I've found these properties highly desirable for using these lenses on a rig with follow focus and matte box attachments. With most follow focus gears, focus direction is determined by the lens. making focus ring rotation a crucial issue. In addition to being able to choose that direction by lens mount selection, the focus ring on the Rokinon 35mm rotates about 120 degrees, giving you very fine control. The fixed outer lens barrel makes it ideal for use with matte boxes and anamorphic adapters as well.

I recently tried out a 24mm f2.0 Nikkor AI-S lens in excellent condition. It was very compact, with beautiful image quality and precise focus control. Unfortunately, I had to conclude that it just wasn't what I needed in either a video or a stills lens. Like most vintage primes, while the front lens barrel doesn't rotate, it extends while focusing, And with AI-S Nikkors, the lack of a CPU chip on the lens mount makes them unusable with the light meters in many Nikon camera bodies. The modern design of the Rokinons makes them much more adaptable to my purposes.

samyang needs to make a really really good 50mm f/1.4 and a very good 135mm f/2 and they'll rule the world:) that way they'll have 8mm 3.5,14mm 2.8, 24mm 1.4, 35mm 1.4, 50mm 1.4, 85mm 1.4, 135mm 2: an entire set of all manual, decent build quality lenses, excellent optically completely future proof (FF coverage) perfect for budget video filmakers. And then one could dream about the same set but with stepless aperture and packaged in a set for good discount:)

Which mount version did you guys get?

really interesting lens - I love Samyang

Oops. I was asking for 35mm. 24mm isn't out yet.

Samyang lists Four Thirds as one of the mount options, but surely they must mean Micro Four Thirds, not the older and longer flange-distanced Four Thirds mount? Does anyone here own the 35mm Samyang in FT mount and can they confirm whether it's native MFT or needs an FT-MFT adapter? Thank you.

@stonebat
Yes, the Rokinon 85mm f1.4 is available both with the Nikon chip, and as a cheaper version without the chip. (Either will work with the GH2, but I'm seriously considering getting a Nikon for its legendary low-light capabilities.)

Hmm, why would Samyang put out a new lens in full FT mount when those cameras are no longer being produced, and MFT is the new Panoly standard? Makes no sense to me, unless the rest of the world is still flush with FT bodies. Not seeing the logic here.

I'm definitely buying the Samyang 24mm, that's a given. Was planning to pick up the new Panaleica 25mm but I'd much rather have a manual focus lens that's sharp wide open. But if the Samyang is really FT mount, then the irony is a GH2 shooter is better off getting the Nikon or Pentax mount depending on which direction you prefer to focus.

Actually with the hacked 42MB setting, ISO3200 is so clean I may as well use my $25 Industar 69 28mm f2.8 and call it a day.
