Very useful APO lens, 280 ~ 800 mm

This APO lens ranges 280 - 800mm is very useful for nature and animal hotographers in particular, who use multiple focal lengths in this range and, with the LEICA APO-EXTENDER-R 2x even up to 1,600 mm. This can be used to replace a range of fixed focal length lenses. As a result, two lens heads and three focus modules instantly create six APO lenses, all providing consistent top-class optical quality from Leica.
