Having looked at other reviews, I would like to emphasize that this is a fully manual lens - no auto focus and no auto iris. The benefit of not having those frills is that the lens is extremely affordable and compact, especially for a fisheye. The lens is particularly good for videos, where autofocus and autoiris aren't that important anyway. Advantages: - Low price. - Clear image. - Durable metal body. - Pretty light for a fish eye. Hood is detachable. Cons: - The F-mount pin tends to get stuck in one of the countersunk screw holes on the mount, preventing the lens from rotating fully. Luckily, this is an easy fix - just press the lens release button while attaching the lens. I wish the lens could focus a little closer for macro photography. Luckily when using a lens on a Micro 4/3 camera like my BMPCC4K it is possible to achieve macro photography with a spool adapter.
