Was at the Leica store looking at the new M240 and tried with the 28mm Elmarit-M Asph. I own this lens, but the one at the store (and in the current catalog) looks slightly different from mine, New one takes E46 filters and I think only stops down to f/16, while mine takes E39 filters and stops down to f/22. Otherwise they look the same.nmSame tiny case and same build. Even the same hood. Is there an optical change? I can see E46 filter size being a benefit its regards to vignetting, but would be interested to know if there are other changes. This is my favorite lens on the M8.2 (where vignetting doesn't really matter with the crop).
