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.

Not a big fan of this lens. The auto exposure doesn’t work that great and it makes it hard to focus correctly. I’ve had better result with cheaper fish eye lens! It’s too late for me to return it. i don’t recommend it!!

Great lens for the price. If you know the various personality issues of a fish eye lens (distortion, etc) and accept that this is manual focus and aperture adjustment, then you should love this lens. It is very solid and well made.

As with all Rokinon/Samyang lenses, it depends on how good your copy is. Unfortunately the copy I received was bad. It could not focus to infinity. I even did some tests where I started at "1 ft." on the focus ring and gradually increased the focus distance on the scale.

It said that this lens would give a circular image, which i have seen with other 8mm lenses on full frame bodies. (I use them all the time for work). This did no such thing, First of all you can see the lens hood which is not detachable, and second it produces a fairly squashed square.

It's not as sharp as I had hoped but awesome value.

Don't let manual focus scare you. This is my second M focus fisheye and I have never had a problem, just put it to infinity and you're golden. I hated spending the money on it but once I got it, oh man was I ever stoked. Build quality is amazing compared to cheaper fisheyes (ex. Opteka).

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...

It's a fun lens, but picture quality isn't the best. Can't expect a lot for a cheap lens though. Don't use it on a full frame camera. Ice got a 6d and a 650d but only use it on the 650. Manual aperture as well, but can usually put in on about f8 and everything is in focus.
