Leica released a second version of the Leica Lux Grips in Silber.

This is a grip that offers additional control options for the iPhone when used with the Leica LUX app. When you purchase the grip, you also receive a 12-month Pro membership for the Leica LUX app.
The app offers additional settings options, just like those found on a “real” camera. You can also select special Leica looks and the look of specific Leica lenses.
