Subject: [Leica] Correct a front-focussing 90 Summicron (Leitz Canada)

As Philippe said, send the 90 Summicron and M9 and say not to touch the 
body. It gets far more awkward when you use more than one digital body ;-)

Thanks John,

I was wondering about sending him everything, but then thought that might 
get expensive! Two things I know for sure:

1. The 90 'cron is badly front-focussing on my M9.

2. My other three Leica lenses (plus a Voigtlander 35/1.2) focus spot-on 
wide open on my M9.

So, if I send him all my lenses, he might get the wrong idea and fiddle with 
all of them and then charge me for that. But because all my lenses bar the 
90 'cron work fine on my M9, then the simplest solution seems to be to 
adjust the 90 'cron so that it focusses well wide-open on my M9.

Just writing that last sentence, I realise I should make sure to tell him 
that I want accuracy wide open to be the priority.

Cheers,

Peter



It may throw your other lenses out.... send him everything

I'm now thinking that perhaps my best course is to send the repair man my M9 
and ask if he can adjust the 90 'cron so that it focusses properly on my 
camera. Can you see any problem with this route?
