Richard,
Things move slowly in Leica World. My Summicron-R 50mm f/2, which I
bought used some years ago, was made by Leitz at their now closed
Midland, Canada factory in 1979 and has been upgraded to ROM. The new
ones are 50 grams heavier so something was changed between 2002, when
the lighter version was deemed "current" in the 7th Edition of the
Hove's Leica Pocket Book,
On the subject of books, the Hove's Leica Pocket Book has provided me
with a lot of information and insight into Leica lenses. It seems to
be no longer in print but used copies are available on Amazon for
around $20. That edition also seems to be the latest.
Also, if you have a moment, go to
http://us.leica-camera.com
and work your way through "R System" to "Lenses" and choose one.
You'll then have a choice of "Technical Data" and "Know How" from
which to chose.
Try both and see if either suits your fancy. The Technical Data
downloads were very helpful to me in understanding the DOF of a couple
of lenses in order to improve my images made in a dimly lighted church
where DOF was critical as everything was shot wide open at the highest
ISO available.
Hope this is helpful to you.
All the best,
Bill

Hi Doug & List,
I am systemically dipping into the Resource a listmember provided
(quite generously) and I am catching onto the incredible lack of
linkage between a lenses' Optical Formula and how many Cams are or
are not hanging off the back of it. While not being a universal
truism, the # of cams is more important as an advisory of which SLRs
the lens will be compatible with and in corrollary an indication of
the physical age of the lens itself. The 'gestalt' of designing the
lens 'correctly' in the first place of the Leica Realm is so much
different than the tailchasing plethora of AF lenses trying to
continually be new and different I grew accustomed to over the last
decade or two.
I'm quite thankful to the inputs people are providing after my
postings and questions. They are sincerely appreciated. I would like
to note that the way Leica lenses were handling contrast and flare
and out of focus transitions & renderings in the images I began
encountering while looking for Manual Focus options for my Canon are
why I'm looking for those lenses to try, experiment with, and likely
fall in love with.

For the 50 'cron there are some differences, mostly at the widest
apertures. In general it's like asking which is a better flavor,
chocolate
or strawberry? Other features should be considered too, such as the
filter
size. The Series VI filters for the early lenses can be difficult
to find
while the 55mm filter size of the later lenses is very common.
One example where I've seen a significant difference is with the 35mm
Elmarit-R (f/2.8). Even when it was current, Leica only described the
first version (Series VI filters) as a 'good' lens while everything
else
was described with superlatives. I found that the later versions of
this
lens (Series VII or E55 filters) are significantly better in detail
rendition and flare suppression.
The cam/ROM configuration isn't a reliable guide to the version
because
most older lenses can be retrofitted with additional cams or ROM.
