Viltrox came out with the first cheap electronic focal reducer. I got it because I'd like to use some Canon lenses that have no aperture ring. Sadly, corners are not quite as sharp and there is a little more bulging. Also, inside the adapter is less space because of electronics, and some vintage lenses wont fit without cutting protruding pins.

Any plans for 4K video review? :-)
