    Summilux 50mm ASPH damaged or normal?

    I found a 50mm/1.4 asph on one of those auction sites, but this looks like it has been mangled with a file:



    Can someone post a picture of their 50mm focus ramp, or verify this is normal?
    Thanks!

    I think it's normal, at least my copy too has this rough rim.
    Noticed this on the 28'cron as well.

    All the best.

    How is that possible? Isn't Leica (never even held a Leica lens in my hands) supposed to be superior workmanship? And that looks quite unfinished to me.

    Thanks for the picture - I did look at my 24/2.8 asph and it was quite a bit smoother than my first post of the 50/1.4

    Amazing such a precision mechanism (the rangefinder) is controlled by such a rough surface. Not much room for error at f1.4

    I took a look at a few more lenses -- both the f/1 Nocti and 75/1.4 are more finished than the 50/1.4 ASPH but still show some machining/file marks.

    Perhaps a rough surface prevents the wheel from sliding on the cam and creating a wear spot? Still looks a bit unfinished to me.

    The rangefinder cam is the inner smooth ring. This looks like a simple cutout so the cam does not hit the outer ring.

    Exactly, I noticed that the longer focal lengths like 75, 90 and 135 are rather smooth, but it's the shorter lengths that apparently need this cut-out.
    Kevin, no worries then - go out and start shooting

    All the best.

    That ring on my Summilux is perfectly finished, but that looks like a Friday afternoon job to me.

    Hi there Steve,

    it's not the ring, but it's the cut-out that's rough.
    It can be seen on my 28, 24 and 21 lenses as well.
    Now - please don't tell me they're all Monday morning or Friday afternoon jobs ...


    Kind regards.

    The cutout on my 50 lux asph is smooth.
    Sorry for the rubbish pic, my RX100 doesn't have very good macro capabilities



    Shall we start the bidding at $5000?

    Out of curiosity I checked my 21/3.4 Super Elmar ASPH and my 35/1.4 ASPH FLE and both are smooth as my lux.

    It is just a miracle that such hacked off lenses work wonders in some hands!

    Lets not get caught up in pointless corrections, I did mean that area of the ring with the cut out in it FWIW all my of eight my modern era Leica lenses have a good finish in this area, so a rough finish can hardly be called normal.

    Yes I'm lucky, but it isn't enough information to draw statistical conclusions, I wasn't even going to mention it until an act of pedantism cropped up.

    Definitely smoother than mine 2007 copy, Mirek.

    All the best.
