Great filter up to 24mm with full frame, it's ok then you can see the edges, performance is excellent..

ordered the 79" K&F first but it was lost in transit so instead I chose ordered this unit. I'm using it for a full frame canon 5dsr with 70-200m and a Sony a6600 with 16-55 Sony lense. The tripod is sturdy and very easy to for 360 degree movement. Great product. Highly recommended.

It slings over your shoulder. It holds about three two four lenses depending on their size and your full frame or APS-C camera. Worth the price.

It would have been nice to have a sheet showing the location of all the pockets. :)Nice that my full-frame Nikon with Battery Grip fits in the camera pocket. There is a separate hand-carried camera case in which my camera also fits.Very nice construction. Something to take pride in!

Works great with my Panasonic S5 full frame camera. Very good fit and finish and fits well on the camera body and M42 Pentax lens. Very satisfied!

This adapter turns a cheap Canon M camera into a professional one. Simply combine it with the full-frame lenses without an L fixed focal length.

use the lens on my Canon 5d II full format camera - I am very satisfied with the imaging performance. Of course there is vignetting with an open aperture of 2.8 - but you hardly take pictures with it anyway. There are certainly better lenses - but you have to put down at least twice as much and therefore I can only recommend the lens to everyone who wants to use it from time to time. Anyone who needs a UWW professionally should take a look at the 11 or 15 mm from IRIX.

bought this lens with some apprehension. I'm a bit of a purist when it comes to my lens collection and apart from one Sigma item I only own Canon glass. I own a Canon 550D and have never felt I could get a wide enough lens (that was also compatible with a full frame camera) for a reasonable price. A friend of mine owns the Canon equivalent of this device and it has always made me jealous. Since it's only about 15% the price of a Canon lens, I didn't have high hopes for the quality of the stills (or movies) this thing would be capable of. How wrong could I have been. For the money, this lens is just amazing. Wide but also very sharp at 100% crop. I am quite amazed at how good this product actually is. At this point (a week of extensive testing) I don't regret buying this lens at all. It works very well for pictures and videos (which is what I mainly use my camera for). Build quality feels solid, my only downside is that the focus ring on my device is a little rough in places. I also don't think this unit will stand the test of time as well as my Canons, although I'm not sure why I think so. In fact, using the lens is also a bit more complicated than its more expensive counterparts - as you've noticed in the description is the full manual; focus and aperture. I can understand that this isn't for everyone, but it didn't pose any major problems for me. Focusing can be a little tricky at times, but having Magic Lantern on your camera can really alleviate that difficulty. When you factor in the price of this kit and the price of its closest competitor, it's a no-brainer. At least it is for me. Looking at the comparison shots of this and Canon's 14mm counterpart, there's only a negligible difference in favor of the Canon. For a £1700 difference it's really not worth it in my humble opinion. If you need a wide angle lens, get this lens. You will not be disappointed.
