I recently bought a new Leica M7 and 35mm lens, as above. Just got my first film back, and I'm delighted with them - the lens often does give a 3D feel. However, on three of the pictures (obviously contre-jour) there is a lot of flare (lenshood on permanently). One of the pictures has a bright orange polygon in the middle of the picture. Is this common in this lens? Cleaned it, carefully, for the first time yesterday, and surprised to note that it has a concave front element! Still delighted with the lens, and the camera, I'll just be more careful in future.
