|The only cosmetic addition to this lens that I do not like is the inclusion of the brushed silver ring around the base of the Fuji model. The design is a bit jarring and looks like an afterthought. I would have like to see this done up in black.|
The lens is completely manual on a Fuji X camera -- manual focus, manual aperture. This is not much of a problem with a fisheye lens considering the extensive depth of field of such a short focal length and the fact that it works best when stopped down a bit anyway. There are no electrical contacts to connect the lens to the camera so no lens data is passed along. You can set your X camera to know what focal length it is using, but that's about it.
The Rokinon is a Korean lens that also goes under the Samyang name. They both come from the same factory in Korea and are exactly the same lens. Sometimes they are priced differently so shop around.
I suspect many photographers will use this lens for astro photography where a lack of coma is important. I did not use it to photograph stars, but did check the city lights in the extreme areas of the frame and saw no coma present, particularly when stopped down 2-3 stops.
There is noticeable lack of vignetting -- something typical in many full frame fisheyes -- with this lens. This means you don't have to open up the exposure in the corners in post processing. Opening up shadows in post increases noise in those areas. So that is a plus for this lens.
I owned a Nikon 16mm full frame fisheye once and got rid of it after using it for astro photography and seeing the distortion mess it created in the edges of the frame. The Rokinon is a much better performer than that at a fraction of the cost -- well worth it for me.
