Enormous field of a view.High resolution in the centre at wide open, or all the way to the edges if stopped down to f8. Very good contrast and colours.Visible chromatic aberration in high contrast areas when wide open. Relatively light weight. Aperture control works perfect from the camera (K 5iis).

I love this fisheye. Placed on a Canon crop sensor camera you get magnification of 1.6x. Instead of 8mm, it becomes a 12.8 mm and this helps you not get the oval fisheye problem that you would see in a full size sensor.

This is what I call a fun lens. I got the Canon version, which is totally manual. This is really not an issue. Once you get the hand of it, it's very easy to use and the pictures look great! On the Canon it covers a field of vision of around 167 degrees. You can get a whole room on one shot.

Really enjoy this wide angle lens. My camera is 80D so I get about 13mm focal length with very little distortion. Took it to my trip on Highway 1 and I loved it.

This is a great fisheye and perfect for milky way and star trail photography. A little bit of a learning curve to use it, but nothing difficult. Very impressed with the build quality. Very solid little lens.

This is a great lens for the price. Do not get the first version with fixed lens hood. This one is detachable, mainly for storage. You still can't put a filter on it. This thing has some new glass in it and is very sharp.

I have not had this lens long, but really enjoy it. The good: build quality is solid with smooth action on the focus and aperture rings; close focus capability allows you to get in very close to a subject; perspective is fantastic; good color and contrast rendition; lens flare reasonably well...

Great price, great photos! If wanting to be a wedding photographer, you may want a little more high quality lens, but this lens is perfect for the price.

Sometimes you're just looking for a fun experience with your camera. One way is to put this lens on your DSLR body and start taking images. This lens is really useful when you just can't back far enough to capture the scene with a standard wide angle lens and you don't want to stitch a number of...

You can’t beat the price on the angles this lense gives you. It’s softer than I’d like. I have taken a lot of advice from people’s reviews on optimal settings, but it seems the variance in quality will leave you to just play around with focus and ape rather. Overall, I would recommend.
