A fisheye adapter for a full frame camera may conjure memories for some of those awful Jessops / Rokinon / Soligor / Teleplus 0.42x semi-fisheye/macro converters every camera shop used to stock, but this Sony converter certainly isn't one of those.

Super cheap and sharp option for a fisheye for the full frame sony setup. The Focus is very fast! Great build! The build of this adapter is even better than the lens.

I typically don't shoot a lot of ultra-wide images. Over the years I find my widest preference around the 24mm focal length. But with this very affordable option to attach to the 28mm lens, I decided to give it a try.
