I have two of these lenses and I would like to trade the other. The lens is quite small, but of course the adapter will add some bulk. It has 49mm filter thread. The lens is in good optical condition, some marks in the coating and very little dust. This does not affect image quality. The depth of field preview button does not function properly, but you can not use this function with m4/3 anyway, as the adapters tend to engage the stop down lever in the lens mount. It has an original rear cap and a Hama lens cap. Example image and pictures of the actual lens can be seen in my gallery https://www.mu-43.com/gallery/u979-krang.html This lens usually goes for 25€ to 50€ (30$ to 60$ or 20£ to 40£). So I would like something of similar value in the trade. I can use olympus OM, Nikon AI, M39, M42 and C-mount lenses. I would prefer Europe, but will consider other places. I live in Finland.
