Lens cover for Canon EF 100-400mm f4.5-5.6 L IS II USM Not including lens, camera body and tripod. Auto focus (AF Version)/Manual focus version(M/AF Version) Read the following carefully before ordering. The AF version of the gun clothig consists of 5 parts. Compared to the M/AF version, the AF version reduces the number of gun parts, and the overall performance is better. The gun clothing is more compliant and the hand grip is more comfortable. However, the manual focus ring cannot be operated after the gun clothing is installed, so only the AF function (For AF only) can be used. Please note before purchase: After installing the gun clothing, the zoom ring and the damping adjustment ring can be rotated independently, usually without affecting the lens operation. The manual focus ring and the stand ring cannot be rotated. The manual focus version of the lens cover consists of 6 parts. Compared to the autofocus version, the manual focus ring can be operated after the gun coat is installed, so the use of automatic and manual focus (For AF and MF) is not affected. Please note before purchase: After installing the gun coat, the zoom ring and the damping adjustment ring can be rotated independently, usually without affecting the lens operation. The bracket ring cannot be rotated. The part of the lens that protrudes at the 400mm end also has a special lens cover. It can be used without being installed. This part of the gun coat will affect the lens retraction after installation.
