GH3 Two different Rokinon 85mm f/1.4 lenses?

[Jaime Valles]

Is there a difference between these two lenses?

Both are 85mm f/1.4 manual focus lenses, and they both cost the same at B&H. So... what am I missing?

Apologies if this is a really stupid question. Thanks in advance!

One is 4/3 and the other is micro 4/3.

Oh! I see. Missed that part. So, you'd need an adapter to use the Four Thirds lens on a Micro 4/3 body.

I guess so but I plan on getting the Nikon mount version to use with my Speed Booster adapter.

Me too. That way I will have lenses for my Nikon and the GH3 (4K when it comes out). Also each lens will have double focal lengths equivalent to full frame for the GH. By example the 24mm lens with the speedbooster will be almost 24mm and with a regular adapter it will be 48mm.

The M43 Speedboster uses a 0.71 multiplier so the 85mm lens x 2 = 170 x 0.71 = 120.7mm. The 24mm would be 34.08mm instead of 48mm so it's actually closer to the 48mm.

So the 24mm will give me a 35mm and 48mm on the GH. That still sounds good to me.
