[Leica] Tele-Elmarits

[Martin Davidson <martin.davidson@bbc.co.uk>]

Apologies if this has been thrashed to death before.  I am looking to add a
fourth lens to my M6 (I have the 28 Elmarit, the 35 Asph summicron, and a 50
summicron).  Having been thrilled by the asph performance of the 35, I was
saving and waiting (and saving and saving) for the new 90 f/2 asph -- but am
worried about its size and weight.  By chance I came across (and rather fell
in love with) an old Canadian tele-elmarit -- at around 500 UK pounds (seems
the going rate in the UK), half the price (at least) of the new asph, but a
lot to pay for a lens that (for all I know) may now be regarded as rather
obsolete.  In short, I am fishing for a few user-experiences of this lens,
for which I would be very grateful.
