Wide and narrow apertures display 0x?? rather than values
Created originally on Bitbucket by hudson (Trammell Hudson)
If the firmware doesn't understand an aperture setting it displays a hex code like 0x93 rather than the real value. DOF and hyperfocal distance no longer work, either.
If you run into this bug, please add a comment with the lens you were using, the aperture and the hex code that was displayed so that the Magic Lantern table can be updated.
