Although not a match for a dedicated 20mm, if you stop it down to f4, it actually performs really well, and costs significantly less and takes up far less space. It communicates with the camera to keep your EXIF right, and feels like a natural extension to the 28mm f2 FE lens. The donor lens becomes an f2.8 by default once mounted, and IQ is acceptable here, but vastly improves, especially towards the corners from f4 onwards. AF works as normal. An inexpensive way to add an UWA perspective to your kit.

A wide angle 21mm F2.8 lens. Excellent value for money.

this len great for outing that not need to take more len out, this len is good to go.

No distortion at all edges with the UWA added. Fits nicely as if it is a single lens. Only draw back is that I cannot use Polariser filter for landscape shots.

28mm is wide enough most of the time, and I keep considering the possibility of a lens around 15mm, but when I need just a little more than 28mm, the 21mm wide-angle adapter fills the gap. It may not be brilliantly sharp wide open, but a 21mm lens typically needs a smaller aperture, so this is not a problem. Only negative is inability to use filters.

I bought this lens a month ago and i like it, the photos are not as sharp as at 28mm, but overall is a good lens! I use this lens for vlogging, and for video it's amazing.

What a great addition to anyones lens collection having the option to add to the 28mm len Quality is superb and up to Sony standards i am very happy with my recent pictures and can only improve with practice with the UWC
