<p>I've just had my Summarit recoated - actually the groups had to be teased apart first, so rebuilt would be more like it - and it's a wonderful piece of glass, now that the thing is spotless and has been optimized with modern gear to current standards.<br>
Wide open it's an instant "antique" Xenon-type large format look, especially in black-and-white and just a stop and a half down it's back to the regular signature Leica 35mm look.<br>
I use it for fashion and beauty portraiture and street / lifestyle shots on an M9, and can compare it with a v8 50mm 'cron and a 45mm f/2 G2 Planar that I also have in M mount. Well worth it, and definitely not for everybody. </p>
