Lenses are valuable items and even a small scratch can mar them forever. Always protect your camera's lens with a lens cap! Keep a spare cap in your gear bag for the inevitable lost lens cap, too! Pinch the sides of the cap and snap it into place - it fits securely and your lenses are covered!Lens cap is compatible with the following lenses + many other lenses that have a 72mm thread:Canon EF 17-40mm f/4L EF-S 17-55mm EF 24-70mm f/4L EF 24-105mm EF 28-300mm EF 70-200mm f/2.8L 70-200 2.8 IS USM EF 100-400mm EF 24mm f/1.4L EF 300mm f/4L EF 400mm f/5.6L EF-S 10-22mm EF 16-35mm f/4L EF 24-105mm f/4L IS II USM Lens 24-70mm f/4L LensNikon AF-S Nikkor 70-200mm f/2.8E FL ED VR Lens 10-24mm f/3.5-4.5G ED AF-S DX 12-24mm f/4G IF-ED AF-S DX 16-35mm f/4G ED VR 17-55mm f/2.8G ED-IF AF-S DX 18-300mm f/3.5-5.6G ED VR 18-35mm f/3.5-4.5G 20mm f/1.8G 24-120mm f/4G ED VR 24-70mm f/2.8G ED 24mm f/1.4G ED 24mm f/3.5D ED 28-300mm f/3.5-5.6G ED VR 300mm f/4D IF-ED 300mm f/4E PF ED VR 45mm f/2.8D ED 70-200mm f/2.8G ED VR II 80-200mm f/2.8D ED 80-400mm f/4.5-5.6G ED VR 85mm f/1.4D IF 85mm f/1.4G 85mm f/2.8D Sony AF 70-200mm f/2.8 APO G Lens 24-70mm f/2.8 Carl Zeiss 70-400mm f/4-5.6 G Lens 11-18mm f/4.5-5.6 DT Lens 135mm f/1.8 Lens 16-35mm f/2.8 ZA SSM Lens FE 85mm f/1.4 GM Lens FE 70-200mm f/2.8 GM OSS LensOlympus ED 14-35mm f/2.0 SWD Lens 35-100mm f/2.0 ED Lens ED 300mm F/4.0 LensSigma 10-20mm f/4.5.6 17-50mm f/2.8 EX OS 70-200mm f/2.8 EX OS 24mm f/1.4 ART DG HSM 24mm f/1.8 28mm f/1.8 50mm f/1.4 EX DG 50mm f/1.4 ART 85mm f/1.4 EX DG HSM
