I was looking for a manual focus lens for the CL, in the 40mm [effective field of view] range, as it seemed a good compromise “carry around” lens for my frequent 35/50 pairing on the MM. I was wondering if anyone had tried the combination of the 28mm f2.8 v4 [pre-asph] on their CL and how they found it? Any smearing in the corners? Color shift? I seem to remember it being used on the M8 successfully by a number of folks, some time back.
