Sony PMWF3K Operating Instructions - Page 28

Preparations If you have attached an aberration correction lens The aberration correction function is activated automatically. Starting the camcorder with an aberration correction lens may require more time than normally because of data loading at start-up. The lenses supplied with the PMW-F3K are aberration correction lenses. Contact a Sony service representative for information about other aberration correction lenses. Adjusting the flange focal length Adjustment of the flange focal length (distance between the lens mount attachment plane and the imaging plane) is necessary in the following situations: • The first time a lens is attached • When changing lenses • If the focus is not sharp at both telephoto and wide angle with a zoom lens The flange focal length for this camcorder can be adjusted by rotating the adjustment screw. Use an Allen wrench (sized 7/64 inch) for the adjustment. Counterclockwise rotation lengthens the flange focal length and clockwise rotation shortens it. Adjustment screw of flange focal length Removing the lens Proceed as follows: 1 While holding the lens, turn the lens mount frame counterclockwise. 2 Pull the lens forward to remove. Note When another lens is not immediately attached, attach the lens mount cap to its original position and secure it by turning the lens mount frame clockwise. Using Lens Files By your storing the data (such as compensation data) specific to the lenses in files, required adjustments and compensation can be performed merely by retrieving the appropriate file when changing lenses.
