All - I'm trying to determine if there's a native m4/3 mount version of this lens, and if so, what are the specs, in terms of size, weight, minimum focus distance, etc... I've done some research on the web, and it looks like there is one listed on B&H, but the photos reference an alternate mount. When I look at Rokinon's site, they only list the regular 4/3 version. I already have the Sony version, along with a m4/3 adapter, but would prefer one with a native mount to keep the package smaller if possible. Thanks!
