I just noticed this today - but it's been around since mid last year. I think it would be an interesting addition to my M equipment - even though I'm actually aiming for maximum compactness. Because a 1.2/35 ultimately delivers more than a 1.0/50 - the shorter focal length allows for longer shutter speeds without camera shake. And the depth of field is greater, making it less critical than with the Noctilux. Besides, with available light, the angle of view of the 50mm is often already too narrow. So the 1.2/35 could be the ideal available light lens.
