Used Leica APO-Extender-R 2x 3-CAM Converter
Leica produced two apochromatically corrected tele-converters for its a R-series lenses, the APO-Extender-R 1.4x and the APO-Extender-R 2x. Like any tele-converter, they enlarge the central part of an image to increase the focal length of the primary lens, while reducing the intensity of light on the imaging receptor. The APO-Extender-R 1.4x increases the focal length by 40% and leads to a one-stop loss in lens speed (a lens set to f/2.8 will become a f/4), and the APO-Extender-R 2x doubles the focal length and results in two aperture stops in lens speed loss (a lens set to f/2.8 will become a f/5.6).
Both APO-Extenders maintain the fully automatic iris diaphragm of the lens with which they are coupled. Also, the closest focusing distance of the primary lens remains unchanged, so that the maximum magnification ratio of the lens is increased. Both tele-converters are highly corrected for aberrations and optimized to work with Leica's APO-lenses, notably its of long tele primes.
