This lens is, of course, the *extremely* tiny MS Optical Perar 35mm f/3.5 Super Triplet MK II.
Today's drive out to Granite Falls gave me the opportunity to put this little guy through its paces - we took mainly back roads, and found some interesting subjects.
The corners of the Perar are very soft when shot at maximum aperture but things are well-behaved by f/5.6 and great at f/8. Though nothing like a Leica lens, there is certainly some real magic going on here - the microcontrast is rather good and the performance is phenomenal considering the lens's size and the fact that there are only three elements.
I'm very happy indeed!
