The magnificent Mamiya 300 f2.8 APO lens in very minty condition. It comes with original hard case, front and rear Mamiya lens caps, and custom 3d printed "Mamiya" lens cap. This lens cap is not like the original included one that is leather. This is much more convenient like a regular friction lens cap. Comes complete and is likely the cleanest one you will ever find. Also available for purchase are Leica S adapter (Leica and 3rd party available) and a Novoflex adapter for Sony. $2500 net. I will take pics if there is interest.
(also available is a 200mm APO f2.8 minty in box). I am 1joel1 on eBay and Fred Miranda for references. I can also refer to references here on Getdpi.
