It served quite adequately on a full frame Sony A7r using 1.4x Clear Image Zoom, but 8mm was just too short for my landscape work. It resisted flare & also rendered quite sharply w/ macro tubes for closeup work.

So far, so good. Its not auto anything, but, as long as you take it as it is, its a really fun lens to use. I have both crop & full frame cameras. I find it more satisfactory on the crop because you see exactly what you will get. For the money, great value.

This lens is great for the price. The photos are super clear and the colors are excellent. I used it set on manual with aperature priority and it worked beautifully. If you set it on f22 , aperature priority and attach to a Nikon D7200 the autofocus seems to work. Will buy another for my Sony.

For this price, i just ordered it without expecting too much. But its image quality is beyond my expectation.WOW! it's got Aperture ring. So the Av(aperture priority) mode works.

This is a fantastic lens to add to your collection for intermediate photographers. The lens is reasonably sharp and most shots are very immersive.The AE chip helps with exposure metering to keep things well balanced and exposed.

Fun lens great optics for price you cant go wrong!

Will not work with Nikkon D3400

Ordered this lens because of the price as I never used a fish-eye lens before. It came packaged extremely well as to prevent any damage. The only thing I wished they would have included was a better manual stating how to use this lens.

Samyang mazes a great Fisheye lens at a third of the cost of the other high end manufacturesNormally Im strictly a Nikon lens buyer but after reading the reviews I wanted to try it out so glad I did ...

Interesting for taking special photos.
