I plan to list this item until December 1st. The item is currently under negotiation for purchase, so it may be removed early. Thank you for your understanding. Leitz Summarit 5cm (50mm) F1.5 This lens has been re-polished by Yamazaki Optical Photo Lens Laboratory. Due to its value, I cannot offer a discount. Please refrain from comments requesting a price reduction. The size section indicates "α E-mount," but it is actually a Leica M-mount with an L39 mount adapter attached (it is an L39 screw mount if the adapter is removed). Leica enthusiasts will know that the front element of this lens is soft and easily scratched, making it difficult to find a decent one on the market. Unfortunately, I have lost the repair slip from Yamazaki Optical Photo Lens Laboratory. Therefore, the items included are the lens itself, the original front cap, and an aftermarket LM rear cap. To be honest, I don't want to sell it, but due to circumstances, I would like to sell it to someone who will cherish it. Thank you.
