Does B+W kaesemann xs-pro filter work with lens cap?

[rogergu]

I heard the B+W slim does not, but not sure about kaesemann xs-pro?

Thanks in advance.

I have regular xs-pro and it does work with caps.
Slim doesn't work because it doesn't have stacking threads.

I thought XS-Pro IS the slim version (as opposed to F-Pro being the standard brass mount). I've been using KSM XS-pro with lens caps without major issues - but you do occasionally need to wiggle the cap a bit - the thicker pinch type cap that is; the thinner, press-both-sides ones are fine.
