Operation confirmed. I couldn't see any noticeable issues or dirt on the lens body, even to the untrained eye. I didn't notice any dirt during shooting either. The images were incredibly beautiful, and I was very impressed. Please consider purchasing only if you understand that this is a used item. Lens: NOKTON 10.5mm F0.95 Includes front and rear caps. No box. Immediate purchase is welcome. I will not respond to offensive comments or price negotiations.
