Yes, manual EF Cinemorimes can be shimmied, no electron contexts to worry about.
But on shorter focal length UWA lenses like the Tokina Mk1 Cine (and Duclos Mod version) which only has less that a 180-degree total focus throw, with witness marks for closer focus distances that are really useable, you have several 1.x then you get 2, 2.6 and 3-feet. After that, you only have and Inf. On the Duclos you go from 4, to 7, then Inf. So for anything close to normal shooting distances of 10- to 20 feet, no witness marks after 10-feet.
With the lack of an available shim kit for the Tokina 11-16, tells me the lens is not user shimable.
That said, perhaps the new Mk2 version currently in process of being released, will have a shim kit.
Shim the inexpensive Cine-like Zoom lens to be Parfocal, then use an EVF to set the focus. With the Duclos Mod, I can zoom in to 16mm, use the EVF zoom and get an accurate focus, then zoom back to the focal length you want. With the zoom Parfocal, focus will be set correctly and very accurately.
You are not going to find many Cine type, or other zooms, that are going to give you a parfocal Zoom and accurate witness marks, unless you spend more than $10K for the lens.
