APO-TELYT-R 280 mm f/4
Product # LE11360
Special
order only |
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. |
