Reference Information
This lens is a full manual lens for shooting movies.

• 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.
NOTE
1. Clean off any dust on the lens surface using a lens blower or a soft lens brush. In case of getting
fingerprints or stains on the lens, use a clean cotton cloth moistened with commercial lens
cleaning fluid, or use lens cleaning paper. Gently wipe in a spiral pattern from the center of the
lens. Be careful not to rub dust across the lens, which may scratch the lens surface.
2. Routine inspection about once a year is recommended, depending on the conditions and
environment of use. Request overhaul, if needed.
CAUTION
Always attach the lens cap, hood cap, dust cap or covers before storage. Storing the lens without
the caps or covers attached poses a risk of fire if the lens concentrate light in direct sunlight.
NOTE
Immediately wipe off any moisture on the lens from misty or foggy environments, using a dry
cloth. Seal the lens in a plastic bag with a desiccant (preferably new) to prevent moisture inside.
Otherwise it may cause the mold or the malfunction of the product.
