I have a question about the Leica M6. It seems that there are a few versions like M6 0.72, M6 0.58....could anyone enlighten me the difference. Thanks.
have a look here for an explanation on the various versions of the m6.
basically, the 0.58, 0.72 and 0.85 refers to the magnification of the viewfinder. generally, the lower magnification helps with wider lenses. if i've not mistaken, the 0.85 doesnt come with the 28mm framelines.
other version of the m6 is the m6 ttl. it's basically an m6 that has ttl flash and a >o< meter readout as opposed to the m6's ><.
