Comparing the 2010 Leica Summilux-M 35mm f/1.4 ASPH to older version

Leica M9 owners might be wondering if the new 2010 Summilux-M 35mm f/1.4 ASPH is a worthwhile upgrade over the original version.

The announcement of the 2010 Leica 35mm f/1.4 Summilux-M ASPH also provides a rare opportunity to compare equivalent MTF charts of an older legend to an improved design. The focal length is identical, the measurements follow the same protocol, so it’s the perfect comparison.

To my Guide and Review of the Leica M9, I’ve added an analysis of the older lens to the new 35/1.4 Summilux-M ASPH, which should help anyone considering whether to upgrade.

I look forward to testing the new 35/1.4 'Lux when it appears in ~ July.
