Sony SEL057FEC is a fisheye converter Sony made for the stunning 28mm f2.0 Sony E full frame lens. It’s huge, and given that the good 28mm it’s not so small, the appearance of the full package is dismaying. the over 400g of weigh are not reassuring either. As far as I know the lens transforms the lens in a 16mm f3.5 equivalent, eating up a bit of light. It’s said to be read on the exif too. I’ll wait to have one to be able to dig into it. (a magnet? some contact?)
compatibility
