In the image above the lenses on the right side are all homebrew lenses I made for the Pentax Q.\u00a0 I purchased\u00a0three Q mount to C mount adapters, took them apart and used only the part that mounts to the camera.\u00a0 The lenses themselves are a 12mm pancake distortion creator\u00a0a 35mm f2.8 and the newest one a 40mm f1.9 from a Canon AF35ML which is currently set to a fixed focus point and aperture\u00a0and works like a macro lens.\u00a0 They are of course manual focus and with the conversion factor the 40mm has a field of view similar to a 220mm lens on a ‘full frame’ sensor or 35mm film.\u00a0 Each one of these lenses has limitations in the quality of the image they produce but are a fun way of experimenting.<\/p>\n\n\t\t
