Here are a few shots form the 50mm/1.5 Summarit on the M8, quickly processed.
In this image I see for the first time qualities from my M8 that I get from the DMR. Here is the full frame. This one at f/2.8 (if I remember correctly).
Image is so-so but a crop helps, perhaps along these lines.
This one exhibits the swirly bo-ke that sometimes works very well in some images. Wide open at 1.5
