7 Artisans 7.5mm f2.8 Fisheye for Micro Four Thirds subminiature Do not buy this ifThe 7 Artisans 7. 5mm f2. 8 is a manual focus fisheye lens for Micro Four Thirds cameras. It's a fisheye, so there's a ton of distortion on purpose but this lens does provide corner to corner coverage. Focusing action is smooth, which is nice; the aperture action has no click stops, which is either nice or not nice, depending on your preferences. Clean glass, good function. Includes front and rear caps.
