Makes me wonder who would be interested in such a lens. Heavy, expensive, at least 1 EV vignetting no exif, no aperture coupling and manual focus.

first 17mm equivalent Ultra-wide len on MFT system, any scenery amateur will like this len. the Optic seems same like Touit 12 on E system and the distortion is sensationally small.   Here in China this len has same price with Touit 12
