[Fixed] I used this lens on a cross-country road trip, using the Blackmagic Pocket Cinema Camera on a suction mount inside the cabin of a truck. Even looking through the window glass, when I switched lenses from a high end Nikkor Zoom to the Kowa 6mm, during the edit, you could see the marked jump in acuity. Given the lack of filter potential (a weakness for a native ISO 800 camera) I could only use this lens at the very beginning and end of the day when shooting in the truck. There was no room for a matte box system, needed to get an ND working. This lens will stand up to most any prime lens, and is a welcome (wide angle, finally!) addition to any pro shooting situation with the Pocket Cinema Camera.

[Manual] I bought this lens to use with a In-line process camera for my laser processing work station. This fixed focal length long focal length lens worked perfectly and I was able to zoom the work area with a clear image. I recommend this product srongly for imaging where the working distance is a constraint.

[1"] A great, sharp ultra wide lens for the BMPCC with low chromatic abberation and distortion. It covers the BMPCC and Panasonic GH4 4K sensor. Downside is that this lens has no front filter thread, but if you search diligently enough one of the anamorphic lens holders will clamp onto it.
