Which ones work with the R8? 3-cam, 3rd cam (i.e., *only* the 3rd cam), and ROM lenses (which are 3rd cam with electrical contacts). > 2) I have seen several claims that you loose some functionality when > using lenses without ROM contacts.

I'm not sure if they currently serve any other use, but other, more informed members of this list will be able to. > 3) Are the 1 CAM, 2 CAM, 3 CAM lenses really just M lenses which have > been retrofitted to fit the R system? M lenses cannot be "retrofitted" for the R system: the lens flange to film distance is radically different, along with things like different bayonet diameter, metering cams, etc. Some R lenses are the same optical design as their M counter parts (the 135mm f/2.8 comes to mind), but largely, these are two entirely different and independent lens lines. > 4) Is there any way to estimate the production date from the serial > number on the bodies? http://www.leica-camera.com/cgi-bin/overview.pl/en/sn2p > 5) I understand that some of the early production R8 bodies had some > bugs in them which were weeded out in the later production runs.

I did a survey on R8 camera reliability when they first came out and was trying to use the LUG Archives search function to find the summary posting... but for some reason, the LUG Archive refuses to search anything other than 2003 messages, regardless of the "back issues" setting. Perhaps it will work in a day or two. Do a search for "R8 Reliability Survey" as I believe that was the title of the posting.
