I recently traveled to southern Africa and decided to add the 7 Artisans 7.5mm f2.8 fisheye lens by to my lens collection primarily to perform some astrophotography and because the price was really attractive. My initial impressions of the lens are very favorable, it is well-made, small and fairly light. This 7.5mm is a fisheye lens that apparently has a maximum angle of view of 180 degrees. With 11 elements arranged into 8 groups, it also has a 12-bladed iris. It is a lens requiring manual focus and aperture adjustments although the price of $140 makes it a no-brainer to add to my lens collection. It is about 2.5 in wide and long and weighs 9.7 oz due to a mostly aluminum construction. I thought I would share some photographs and techniques using this lens on my Lumix GX8 camera.
