This is the Thypoch SIMERA 1:1.4/50mm ASPH. in silver. It is a Leica M-mount lens. I am selling it because I haven't used it much. It's incredibly sharp from the widest aperture and performs excellently, comparable to Leica lenses. I hope to pass it on to someone who needs it. The box is not included. It has been stored in a dehumidified storage cabinet. It can focus up to 45cm, making it convenient for table photography, etc. This is a used item. Please refrain from purchasing if you are looking for a new item or are overly concerned about condition. Thank you. I have selected a different mount because Leica M-mount is not an available option.
