Slightly off topic, but I would love to see what the Canon QL 50/1.7 lens looks like in M mount. Any chance we could see that?
I also looked at the MS-Optical website to see the list of lenses that can be converted (and how much). I was absolutely delighted to see the Minolta Hi-Matic E 40/1.7 in that list, as well as the Rollei Zeiss Planar 50/1.8 (QBM mount). Those are the two lenses that have had the greatest influence on my strong affinity for high quality prime lenses and rangefinder cameras in general. Those 2 lenses exactly. So now I'm thinking of converting these for my M system. Why not? My Hi-Matic doesn't work anymore, and I sold all my Rollei QBM gear (except that Planar, for some reason).
Back to the topic. This new 35/1.4 looks beautiful, and I'm sure it will perform just fine for most shooters. Most serious shooters learn to work with their lenses, and even exploit "errors" to their advantage. I wish I could afford one of these.......but then, I need to figure out how I'm going to convert my 40/1.7 and 50/1.8 now. The cost might be "reasonable" considering what you get, but its still a fair expense.
