My mate uses old Olympus lenses on his XE1 and I use a bunch of super takumar lenses with a canon adaptor.
The fujis are way better for this as they have focus peaking whereas modern dslrs lack any real visual focusing aids. My adaptor is electronic so kind of tells the camera when something's focused but it's not reliable and thinks every lens is f/1.4
