Product Description
The Rokinon 8mm f/2.8 UMC Fish-Eye II lens is the second generation of this popular lens for mirrorless cameras. It offers a 12mm focal length equivalency (12.8mm for Canon M) in the 35mm format with a 180° angle of view and a minimum focus distance of 1'. Two aspherical elements and three ED elements minimize aberrations and create clear, high contrast and color-accurate images. A built-in petal-shaped lens hood helps to deflect stray light and protects the front element. The lens's mirrorless mounts include Canon EF-M mount, Fujifilm X mount, Samsung NX mount, and Sony E mount.

The only thing I don't like is that the close focus is not very good--this only affects a very small portions of the shots I would ever take, so it's not a major issue to me, but please take note. It's close focus is about 1' away, which is not close enough if you want a small flower or feature to fill up the frame (or even if you want the gimmick shot of the person or dog with a "big nose"). I believe the older, f3.5 fisheye has a closer focus, at least my friend's alpha mount version does. Extension tubes are too thick to allow macro focus on such a small-focal lens, but I found I was able to remove the lens and pull it out about a milimeter to enable close focus, but this required the lens to be rotated 45 degrees to half fit in the bayonet mount, and then the petal hood, no longer aligned, cut off the edges of the image. Since you can't remove the hood on this lens, its not easily corrected.

It's a good price. It's reasonably good quality glass and the build quality feels solid.
It's also a really compact size for a fisheye, which is really nice. I've got it on an a7 ii, which keeps the total camera size down to something that's very easy to carry around without too much hassle and still get some cool pictures.
It's not the widest angle you can find, and not the best glass, I suppose. It's got no tech in it and is only APS-C you have to make sure your camera will drop to APC properly, which is a little annoying.
But all-in-all this is a very good lens. I'd definitely recommend picking one of these up.
Straight from the camera, as you can see in the first two shots (made with the Rokinon 8mm f/2.8), there is quite a bit of distortion with it being a fisheye. If you're using this for real estate photography, you're probably going to want to use something like a Lightroom profile or some other software to straighten the photos from this lens out a bit.
Overall, I'm pretty satisfied with this purchase!

Thus it is very useful for taking pictures in tight interior spaces, and also for sweeping panoramic landscapes.
I have 2 Canon EOS M cameras (M5 and M6II) along with most of Canon’s EF-M lenses, the widest of which is an 11-22mm. I wanted an even wider-angle lens but was reluctant to try a non-Canon lens, especially one that doesn’t contain the EF-M electronics that control focus and exposure. But I took a chance on this lens, and have been very pleased.
Unlike all of Canon’s EF-M lenses, this is a “dumb” lens, i.e. it has no electrical connection to the camera body. That means it has several limitations:
It’s not an auto-focus lens, thus you need to focus in manually (like in the old days).
It can’t participate in the camera’s auto exposure system. You set the aperture mechanically using a ring on the lens, and that’s the aperture that is used.
It doesn’t report lens information to the camera for use in the camera’s lens aberration control mechanism or to be recorded in the EXIF information that the camera embeds in each photo to tell you which lens was used and the exposure information.
And in the camera’s viewfinder, the aperture is reported as “F0.0” since the camera has no idea what you have set the exposure ring to.
What does this mean? I think the first 2 items are easily dealt with by anyone who knows photography well enough to have the kind of camera this attaches to. The last 2 items are issues for me, albeit relatively minor.
The lack of autofocus is not an issue on a wide-angle lens since you are already far away from the subject and usually have almost no depth of field. I just set the lens on infinity and check back to see that it has not been changed from that, and my shots have been very sharp.
The Rokinon instruction manual says that (for Canon) you should set your camera to M (manual) exposure, but I put mine on Av (aperture priority) and let the camera choose the shutter speed and ISO after I have selected the aperture manually on the lens ring.
The good:
I love, love, love the extremely wide-angle capability this lens provides. The image completely fills the frame on my EOS M cameras, and even without any post-processing you would almost not notice the small amount of “fisheye” distortion unless you have tilted the camera.
The F2.8 aperture gathers a lot of light.
It has a built-in non-detachable lens hood, which is good because the lens is highly convex and protrudes a good distance. Thus you CANNOT put a filter on this lens, regardless of what is stated (but not a problem for me).
Bottom line:
This lens is a great addition to a Canon EF-M stable, and very useful as a tool for obtaining ultra wide angle shots, especially in interiors. I like it a lot.
