What is the range extender after Leica R transferred to Canon?

Leica R was equipped with a 1.8 rangefinder after it was transferred to Canon. The rangefinder is now combined with Leica eyepiece, allowing magnification of 45 to 90 times. This unprecedented zoom range expansion, wildlife, natural and astronomical observation and digital photography, has become a greater pleasure. The integrated automatic locking on the bayonet connector allows a quick and simple connection between the extended program reporting range and the eyepiece.
