Just this weekend, a member of one of the numerous M4/3 clubs around facebook decided he no longer had a need for this particular glass and so I decided to purchase it.
This fast prime at 50mm gives an effective focal length of 100mm on an M4/3 camera which is already a moderate telephoto range but is very nice for portraiture because of the comfortable distance that is afforded by the length. It has 8 aperture blades inside and a distance scale as most manual lenses do. The lens is mostly made of metal which gives it a heft that adds to stability when shooting handheld.
It requires an adapter to mount it to the M4/3 receptacle as you can see above; this lengthens the lens profile to about 1.5x the original.
Currently it is glued to my GF3 because of the ease of focusing using the entire screen rather than through the EVF, and because it is fast enough, I am able to shoot in low light with relative ease with only the need to focus on the subject left to consider.
Color fringing on high contrast areas is quite apparent on this glass but apart from that this is quite a wonderful addition to my roundup. Sample images can be seen on the blog post right after this one do check em out.
