My 907x-50c arrived, and while I'll post a more thorough review of this amazing little gem, what I found most remarkable is that pretty much all of the XCD lenses are optical masterpieces. I don't have an X1d, and have been waiting for the 907x before jumping into the XCD world.
Those who have seen my posts previously on the Leica User Forums, or the various PhotoRumors sites know I'm pretty geeky and exacting when it comes to image quality. I've written many test reports of some of the best lenses and sensors ever made, including Rodenstock HRs, Schneider blue rings for Phase One IQ3 and IQ4, Leica's flagship M lenses, Sony's GM lenses, etc.
But I don't think I've ever seen a set of lenses that were so uniformly excellent overall as these XCDs: 21/4, 30/3.5, 45/4P, 65/2.8, 80/1.9, 90/3.2, 120/3.5, 135/2.8 with or without 1.7x teleconverter. They are all quite outstanding in multiple ways—edge-to-edge sharpness, color, bokeh, low distortion, low CA, low coma, etc. Autofocus (especially after updating all the lenses' firmware to the current versions) was much better than I expected, with very high accuracy though speed is not going to set any records.
Thank you to Steve Hendrix at Capture Integration, who was able to get me nearly a full set of XCD lenses the day after I ordered them—a testament to Steve's excellent customer service.
