Compatibility, Size and Fit
This lens is described for Canon EF/EF-S DSLR bodies and excludes Canon M and R-series mirrorless cameras. It is named with examples including EOS 5D, 90D, 80D, 7D and Rebel series models. Check the exact camera mount before choosing an offer, especially if your camera is mirrorless or uses a different mount.
What Else You May Need

How It Works
This is a manual focus zoom lens. The focus ring is positioned at the front of the lens and must be turned by hand to achieve focus. The aperture range changes with focal length, from f/8.3 at 420 mm to f/16 at 800 mm.
Setup and Correct Use
After fitting the lens, switch the camera to full manual mode. The lens does not use electronic contacts, so the camera may show a no lens error unless manual settings are used. The camera menu option to release the shutter without a lens is also named as a useful setting if the error continues.
Care, Cleaning and Storage
The lens is described as having robust construction and high-quality materials. Keep the front element and filter thread clean, and store it safely when not in use to help protect the lens body and focusing controls.
Before You Decide
Confirm that your camera uses a Canon EF or EF-S mount, because this lens is not for Canon M or R-series mirrorless bodies. Check that manual focus suits the way you shoot, and make sure the 62 mm filter size matches any accessories you plan to use.
