What a lens! The quality feel is outstanding. The weight only is remarkable for such a small lens - yes, I opted for the chrome version. Focusing is smooth as butter, the aperture ring is perfectly distinct. Just holding it in my hand reinforces confidence and putting it on my grey M9 makes it the most beautiful camera on the planet in my humble opinion :) Optically it is a masterpiece and I truly feel very lucky to own it. I look forward to get to know the Summilux intimately and share plenty of photographs with you.
