Purchased in 2023 and used only a few times a year for wildlife photography. The lens exterior was cleaned at Camera no Kitamura on May 13, 2025. I look forward to selling it to someone who will continue to use it. It has been stored in a dehumidifying box. The Canon RF 100-400mm F5.6-8 IS USM lens is ideal for wildlife and sports photography with its excellent focal length and lightweight design. - Brand: Canon - Model Name: RF 100-400mm F5.6-8 IS USM - Focal Length: 100-400mm - Maximum Aperture: F5.6-8 - Accessories: Box Thank you for viewing.
