This lens is a full manual lens for shooting movies.
Cinema lenses were developed primarily for movie production, and have a color balance typical for movies. This
means that the color reproduction is warmer (shifted toward yellow in the CCI coordinate system) 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.
EF Cinema lenses were developed primarily for movie production, and the T
-numbers are indicated on the iris ring
of the lens. On the other hand, the iris information from this lens to the camera uses the F-number in consideration
of use together with conventional EF lenses. Therefore, the camera side displays a different value (F-number) from
the indication on the iris ring of the lens.
