jtbthree Posted January 15, 2011 Share #1 Posted January 15, 2011 Advertisement (gone after registration) My new 50mm Summilux 1.4 ASPH lens came with the normal soft black lens case, but had a very large light gray dot on the bottom of the lens case (painted on the leather, not a "sticker") - does that signify anything, like being retrofitted with the 6-bit coding???

michali Posted January 15, 2011 Share #2 Posted January 15, 2011 I write the lens name on there, it makes it easier to identify which lens is in which case. Link to post Share on other sites More sharing options...
lct Posted January 15, 2011 Share #3 Posted January 15, 2011 Don't know if it means anything but many of my M and R lens cases have this dot, including uncoded ones. Link to post Share on other sites More sharing options...
Walt Calahan Posted January 15, 2011 Share #4 Posted January 15, 2011 The mystery of the Gray Dot. You'd think they'd use a red dot. HA! Link to post Share on other sites More sharing options...
andybarton Posted January 15, 2011 Share #5 Posted January 15, 2011 It's for writing the focal length / aperture of the lens on, so that if you have several similar sized lenses stored in a bag, you know which one is which. Link to post Share on other sites More sharing options...
stunsworth Posted January 15, 2011 Share #6 Posted January 15, 2011 It's for writing the focal length / aperture of the lens on, so that if you have several similar sized lenses stored in a bag, you know which one is which. That's assuming you use the cases. Personally I don't. Link to post Share on other sites More sharing options...
twittle Posted January 16, 2011 Share #7 Posted January 16, 2011 Advertisement (gone after registration) It's for writing the focal length / aperture of the lens on, so that if you have several similar sized lenses stored in a bag, you know which one is which. I've always assumed it was an homage to the white dot on the film M's shutter that's used for spot metering. Link to post Share on other sites More sharing options...
ho_co Posted January 16, 2011 Share #8 Posted January 16, 2011 That's assuming you use the cases. Personally I don't. Steve, you can send them to Leica as proof-of-purchase tokens for a discount on future case purchases. Link to post Share on other sites More sharing options...
lars_bergquist Posted January 16, 2011 Share #9 Posted January 16, 2011 It's so you can see which end is top. The old man standing on his head Link to post Share on other sites More sharing options...
farnz Posted January 16, 2011 Share #10 Posted January 16, 2011 It's for use in the factory so that when hundreds of leather cases are sitting side by side it's easy to see which ones are the wrong way up. Otherwise they'd have to pick each one up and work it out by the position of the zip. Pete. Link to post Share on other sites More sharing options...

luigi bertolotti Posted January 16, 2011 Share #12 Posted January 16, 2011 Always at "factory-level" it could even have something to do with an automatic packaging machine , if they use one for final casing. Link to post Share on other sites More sharing options...
Nicoleica Posted January 16, 2011 Share #13 Posted January 16, 2011 I thought that they were added in the days of earlier film cameras. So that if your shutter tore, you could repair it in the field by cutting a new one out of the base of a lens case that included the metering patch. (Provided you were carrying your Leica 'Solms camera knife' with all of the little thingamibobs, of course. ) Link to post Share on other sites More sharing options...
MarkP Posted January 16, 2011 Share #14 Posted January 16, 2011 Someone should tell Leica after all of these years that its too small, and the wrong grey, to use as an 18% grey card in the field:D Link to post Share on other sites More sharing options...
