My reading of the various postings regarding the new Summarits suggests that the 35mm might actually have a new formula, with an aspherical element added, but we'll see. On another forum someone had asked about the 75 2.5 I use with the Sony a7r. I had a copy of the old PDF that I posted for him, but I could not find the official ones where I thought they used to be. I wonder how Leica evaluates its sales into the non-Leica camera base. The WATE and everything above 50 mm is better than anything else on the Sony (unless perhaps one has a porter to carry around the new huge Zeiss top end).
