Up for sale is a MS Optical Sonnetar 50mm f1.1 serial number 730. This hand assembled lens was purchased last year(2015) from Bellamy Hunt of Japan Camera Hunter.
This lens is in fairly good condition. While in my possession it was very actively used. This means the lens does show signs of used. The optics are nearly immaculate, with no visible scratches or blemishes. The lens does have a little bit of dust on the inside. Below it or not, it actually came that way from Japan.(i guess that's just par for the course when it comes to handmade artisan goods such as this lens) Please refer to the pictures to get a decent reference of the condition of the lens.
