    Back Focus FS5
    #1
    Default
    I recently rented out my FS5 to a regular customer, and when he returned it he said he was having problems with the back focus being out.

    Can anyone point me in the direction of a good tutorial or guide to fixing this problem? The camera is used with Canon EF glass and a Metabones Ultra Speed Booster.

    To my knowledge the Fs5(nor 7) has any type of backfocus adjutment. The F5/55 does, but that’s a very rare thing, unless you count shimming PL mounts on PL cameras(but it’s generally the lens that’s shimmed). It’s usually a function of the lens(or as mark said, the speedbooster). So it was either the lens used, the speedbooster used or a combination of the two that caused the problem.
