In 1993, Leica introduced the Apo-Telyt-R 280 mm f/4, an apochromatically corrected lens with internal focusing. It was among only a few R lenses to be almost entirely free of distortion, as well as delivering the highest resolution with optimal contrast rendition and colour fidelity over the entire focusing range – even at full aperture.
The Apo-Telyt-R 280 mm f/4 comprised seven elements divided into six groups. The new lens offered a vastly improved lens design and image quality compared to its predecessor, the Telyt-R (II) 4/250 mm (introduced in 1980). Its resolution reached an incredible 500 lp/mm, while optical aberrations were minimised to the point of being virtually invisible.
A rubber-armoured lens hood, offering protection from impact damage, and a rugged tripod base made the Apo-Telyt-R 280 mm f/4 an ideal lens for animal and landscape photography.
