New USA Cat #11360- This apochromatically corrected lens with internal focusing is free of distortion and it delivers the highest resolution with optimal contrast rendition and color fidelity over the entire focusing range – even at full aperture. The rubber-armored lens hood, protecting it against impact damage, and a rugged tripod base make it an ideal lens for animal and landscape photography. And it bridges considerable distances, bringing distant objects up close. Thanks to its compact size, it is easy to use for hand-held photography. It focuses down to 1.7 m (5'7") for a reproduction ratio of 1:5. The LEICA MACRO-ADAPTER-R transforms it into a full-fledged macro lens. Attaching a LEICA APO-EXTENDER-R 1.4 x or 2 x creates the high-performance combinations 400 mm f/5.6 and 560 mm f/8.0. With the LEICA APO-EXTENDER-R 2 x, a reproduction ratio of 1:2 can be achieved.
