TTArtisan 50mm f/0.95 (for RF mount). Used a few times for cherry blossom photography. I think it can also be used indoors or for illuminations. The warranty period has expired as it has been over a year since I purchased it new. Items to be included: ① Everything that came with the new purchase ② Hood, hood cap. Operation is not a problem. Dust is visible in the lower right of the lens in the third photo, but it was removed with a blower, so it is in a clean condition, and the inside of the lens is also clean.
