I bought a used 50 cron for my M8 a few years back. It appears to be a 5th version, with removable plastic slotted hood. It says Leitz, not Leica, and was made in Canada. According to the serial number chart, it appears to be manufactured in or around 1981.
I've sold my M8 and now have an M9 on order and am trying to decide what to do about a 50, now that that focal length is more relevant. If given the finances, I'd get a new 50 Lux ASPH and be done with it, but just can't do it all at once.
I was never thrilled with it on my M8, Can't really say why, just didn't seem to have the sharpness, color or micro contrast I wanted. Mostly it just sat in the bag.
So my question is: Now that I need a good 50, a go to lens, I started to think about it again. Is this a decent lens? Is it worth sending in to get a cleaning and adjustment, possibly 6 bit coding? Or was the lackluster performance I saw with it on my M8 as good as this lens will do? Anybody have experience with one?
