Asked by: Roderick
On the Sony aps-c bodies the 21mm ultra wide conversion lens will give you 31.5mm. I used this combo on both full frame and aps-c bodies and it works great.

Can it compatible with sony Carl ziees 55mm f1.8 ...

Can it compatible with sony Carl ziees 55mm f1.8 ?
Asked by: Sok
I am happy with the good sharpness of the 21mm adapter for the Sony 28mm 2.0 lens. The two components were very carefully matched to act as a single lens with lens elements of each half coming close to each other without glass touching glass. I have never tried putting the 21mm on another lens that it was not designed for. If you try it and the threads do match on the 55mm lens, you should take precautions to insure that the front 55mm lens element and rear 21mm adapter elements do not touch. Even if glass elements did not touch I would be surprised if the edge sharpness would be as sharp as it is on the 28mm Sony. Wishing you the best with your experiment!

question

Can one apply an ND filter to the 28mm f2 lens first (for video) and then add this on top of that so that I can shoot video in bright daylight at f2.8 with this?
Asked by: Jamie
I don't think so. I don't have circular ND for 28mm lens, but I attached UV filter on this lens. When I Put 21mm converter on 28mm, I have to remove the UV filter, otherwise I can screw in the converter. Same as the 16mm converter which I also own.
