Purchased from the official Canon online store at the end of 2022 (with a delivery note). Used mainly indoors and stored in a dry cabinet when not in use. Maintained annually, so in good condition (most recent maintenance performed January 2025). No mold, haze, or dust observed (visually). No problems were found during use. The maintenance technician also mentioned that there was hardly any dirt. Selling due to equipment consolidation. *I am confident in the condition, but please understand that this is a used item. Please ask any questions before purchasing.*
