I have Olympus OM 50mm f3.5 macro lens for sale. The set comes with original Olympus 25 extension tube (for even higher magnification), m43 adapter, skylight filter and three caps (including a cap for m43 adapter). It also includes Olympus OM box (albeit made for 28mm OM lens but fits this lens perfectly). The lens is in very good condition, it’s very clean, no fungus, scratches, etc. and works great. I am asking $149 for the entire set including shipping in the US. In addition, I have a portrait lens Olympus 50mm f1.8 which is in absolutely pristine, virtually like new condition. It is the latest generation of that lens with a serial # 5,111,375 and is noticeably sharper with no ghosting or contrast loss wide open compared to older versions. If bought together, I can include this lens for additional $29 (the lens also comes with both caps).
