Jono, one function that you and Sean Reid really can serve is to keep Leica's marketspeak from running away from engineering reality (and also photographer's reality). I recall in the M8 days Leica was extremely reluctant to explain how their files were compressed (lossy, by a simple algorithm that was quickly identified by a Russian blogger). This time around, Leica is saying to all who ask that they correct distortion optically, not in software, but Sean Reid (with Sandy McGuffog's AccuRaw software) finds this is not true. The 23/2.0-2.8 prime does correct some quite visible barrel distortion in software. The lovely m43 PanaLeica 25/1.4 also has considerable barrel distortion which must be corrected in software, so maybe this isn't terrible. It will, however, mean that once again the choice of raw conversion software that is used will introduce important variations in the results with the T.
Another interesting aspect that Sean exposes in his review is that the 23 TCron focuses incredibly close, but with an interesting restriction -- the maximum aperture starts changing from 2.0 at 0.5m and drops as low as 2.8. 0.5 meters! Modern Leica RF lenses stop at 0.7 m for obvious reasons like parallax error, and the 35/1.4 FLE uses its FLEs to get there without focus shift problems. But how close does the new effective 35mm focus on the T and how do you like the results?
All that grumbling aside, I viewed Andreas Kaufmann's Zen meditation video, and the 45 minute conceptual art piece on polishing a machined block of aluminum with a mixture of horror, amusement, and admiration. That's the style!
