I purchased and used this several years ago. I am selling it because I no longer have the compatible camera. This is an adapter for using M-mount lenses on L-mount cameras. Compatible with: sigma fp/fp L Panasonic S5, S1 series, etc. There are signs of wear such as scratches and minor marks, but it is generally in good condition. There are no issues with the operation. Please feel free to ask if you have any questions.
