Note
This lens is a full manual lens for shooting movies.
• When used to shoot still images or when manual operations are performed in AE or other Auto modes, the lens may not
operate properly or the indications may not be correct.
• Do not operate the lens during initialization of the camera settings.
• This lens is developed primarily for movie production, and have a color balance typical for movies. This means that the color
reproduction is warmer than that of EF lenses which are basically used to shoot still images. Therefore, when using both
types of lens together, adjust the color balance (redo the white balance etc.) as necessary.
• In general, the depth of field becomes shallow and the focusing range becomes extremely narrow near the widest aperture
and when shooting a subject at close range. In addition, this tendency increases for lenses with longer focal lengths. When
shooting images, carefully check the focusing condition using the zoom mode of the finder or other means, and shoot a
sufficient number of test images before performing focus operations.
(for EF mount Lens only)
• The T number is printed on the iris ring of this lens, but the F value may be displayed on the camera side.
• Information of the focal length displayed on the camera side omits the figures below the decimal point.
