Comment:
If you want an ultra-wide rectilinear lens (especially a lightweight one for gimbal work), this should be near the top of your list!
The maximum aperture is pretty slow (f/4.5 is the max at 10mm and f/4.8 at 11mm), however, it is very sharp at maximum aperture, good enough for 4K.
Since this is a Canon EF-S lens, it has some vignetting on the 4.6k sensor (since that sensor is larger than the Canon APS-C sensor). Thankfully, however, if you zoom in to 11mm, the vignetting is gone and is gone from the rest of the zoom range. (So, if you have a 4.6k, just pretend it is a 11-18mm f/4.8-5.6!)
Another downside is that it is focus-by-wire. However, given its short focal length and narrow aperture, you'll rarely need to pull focus. Furthermore, this lens is ideal for gimbal/drone work as the lens can be electronically-focused from LAN-C remotes connected to the Ursa. (However, if you need to use a geared system, this lens will likely prove challenging.)
At ~$300, there were bound to be compromises, but I have yet to find a better ultra wide other than the Arri UWZ (~$53,000). (The new Sigma 12-24mm f/4 Art looks promising, but it is not as wide and it will not accommodate a screw-in ND filter due to its bulbous front element.)
