I was in Cooter's late yesterday and talked to Chris Cooter about the M8. They are supposed to be getting them some time shortly after Photokina.
But there may be a chance to try one out earlier. There is a
Leica Workshop going on in Fredricksburg in late October. Cooters have asked Leica to have an M8 there. If this happens, those at the workshop would have a chance for an early test of one.
On the lens front, I got to look at the 75mm f/2.0 'Cron. It's a lovely thing and I learned they had never gotten one back. I also tried the 35/1.4 'Lux on an M7 body and think I'll stick with the 35/2.0 'Cron as it's much smaller and more what I would look for in a "walk around" on a Leica.
