Never, no no never, ever, in a million years, no no, really, no, I mean it, never ever sell Leica.
I have over the years worked my way through a number of LTM, M and R bodies and lenses. It would be true to say that I have bought twice on many an occasion... 2 M6, 2 DR Summicrons, 2 90mm Collapsible Elmars... the list goes on. Problem is, once you have used a Leica lens or body it imprints itself on your consciousness. Months or years later you reach out for it - and it's gone. Then you see it in a shop window, or in extreme cases, go on a quest to replace your lost love.
Don't do it.
Regards,
Bill
