For my part I use my FujiFilm X-T1 with its handle MHG-XT and XT Eyecup EC-L. There is very very fair at the height. Neoprene is deformed by the upper part ("Prism") the case.
With or without the handle MHG-XT and XT Eyecup EC-L, it also remains very fair at length with the XF 18-135 and visor mounted upside down.
In 2 cases, we must get the neoprene to close but this lodge :-)
The 2 buttons hold well this is what counts.
Finally the online help for the choice of the site Optech USA case was not deceived (English only touch).
