Discussion Forum Leica M System M Lenses Leitz 5cm F1.5 Xenon, Leica's first Super-Speed lens.
  • #10697

    I picked this lens up a few months ago for $400 off ebay- had some internal Haze. I got some tips for disassembly on Leicaplace, was able to get to the inner surfaces with the issues. The glass cleaned up nicely. This is an uncoated lens, 7 elements in 5 groups. After using it on the M Monochrom and M9- I’m impressed. More flare that the Summarit, not quite as sharp wide-open as a contemporary Sonnar. which i also brought along,

    Wide-Open, Series VI orange filter in use.

    I believe the shape of the aperture of this lens is to minimize focus shift.

    I will be writing an article comparing the Xenon and the uncoated/pre-war Sonnar 5cm F1.5 on the M9 and M Monochrom.
