The Canon FD 7.5mm f/5.6 Fisheye lens is a film era full frame fisheye lens that also works on crop sensor cameras. We used our Fotodiox Canon FD to Micro Four Thirds lens adapter to mount this retro lens on an Olympus OM-D E-M10 camera. - - #fisheye #fisheyelens #canonfdfisheye #CanonFD #olympus #OlympusOMD #OlympusOMDEM10 #OlympusOMDEM10markiii #fotodiox #fotodioxpro #fotodioxadapter #lensadapter #manuallens #vintagelens #wideangle #cornfield #plants #farm #harvest #microfourthirds #7mm
