Thank you for viewing. I purchased this for underwater photography with diving, requesting it from a shop owner in Izu. However, due to the COVID-19 pandemic, I was unable to go, and it has been stored at home ever since. As I am also elderly, I decided to list it, hoping to offer it at a low price to someone who is just starting out with photography. ★ The camera body to which this lens connects is listed as follows: 《Sold》【New, Unopened】Canon EOS 5D Mark IV Body Original Price → 262,206 yen - Sold ★ I also purchased lenses to attach to the above-mentioned body.
