Leica has released a firmware update for the Leica M9 full-frame digital rangefinder camera. Enhancements in version 1.162 include an “improvement of the sensor homogeneity for wide-angle lenses”. There is an additional colour calibration for all wide-angle lenses, which minimises chromatic deviations between image centre and image corner, especially in critical shooting situations. Additionally, internal software processes have been optimised in order to improve overall system stability. You can download the update from the website below.
