Subject: RE: [Leica] Re: Modifying the 21/3.4 to meter with an M6

there have been various pieces of Leica information suggesting that 
S/Angulons above a certain serial number (2,473,251) will meter on the M6. 
This is incorrect, I guess they meant they were modified not to actuate the 
M5's swinging arm and were therefore safe to use on the M5, this is the 
explanation in the latest Leica literature.
I know that when I attempted to check this out with my late example (past 
the certain number) there was no response from the M6's meter.

I know the page well. It is no longer up but I have it bookmarked on my 
computer (I'm at the office). I will try to look it up and forward it to 
you. Indeed as Henning points out, it is a definitive modification and 
frankly one that I don't think you need to make. Believe it or not you CAN 
meter with the lens the way it is. However you must recalibrate and I 
believe it turned out to be a two or three stop shift in sensitivity, but, 
importantly, it does work. It becomes less useful in low light situations, 
but in normal lighting, it worked fine. Just mount it up and experiment how 
many stops you have to shift the meter. Let me know if you have any more 
questions and what you discover.
