Excerpt: I bought this fisheye for fun, had a great time taking photos with a new perspective. The price is very reasonable. It is not the sharpest lens but very respectable. F stop of 3.5 is slow for inside a building or with movement. Size wise, it is perfect for micro 43, does not add much weight at all.
Excerpt: With this lensi you can take photos at ISO 100 in extremely low light situation. It's only 3.5 aperture but with that wide opening it's enough for taking photos without extra support (just by hand) at so slow shutter speed than 1: 2,5 without problems. Manual focus is not a problem either.
Summary: I love fisheye lenses; I own the 8mm Samyang fisheye for Canon EF-S mount and had great fun with it. This one is even better! Because it's so tiny, mounted on my Panasonic GX7, it's really easy to position it in interesting location.
Summary: I have the Rokinon version of this lens, another brand is Bower, all are actually made by Samyang. I also use it on a GX7 and I have to say I have a completely different experience than the one-star reviewer -- this lens is super-sharp and has become one of the favored lenses in my kit.
Excerpt: This is an exceptional lens. Don't let the price tag fool you. Some of my favorite shots have been taken with this lens. Just take your time during composition and mind your toes and knuckles.
