Model Name: TTArtisan 50mm F2.0 Thank you for viewing. I am selling this lens to change my equipment. It is a manual focus lens, but it is lightweight, bright, and easy to use. The rear cap is a 3D-printed homemade item and is not very clean. A black mist filter is attached to protect the lens. I will send this along with the lens. Regarding the condition of the lens, I have never felt any problems using it, but I am not the type to handle equipment very carefully, so there may be some scratches.
