Alongside the RF 24-105mm f4-7.1 IS STM lens announcement, Canon has also revealed the development of the RF 100-500mm f4.5-7.1 L IS USM, Extender RF 1.4x and Extender RF 2x for 2020.
It's clear that Canon is committed to its new EOS R system and the RF mount, with nine RF lenses promised for 2020. What's also interesting is that the first lens is a distinct step from the fast, bright, 'look what we can do' lenses of 2019, focusing more on the more affordable, lightweight lens.
There are no further details as yet for the RF 100-500mm f4.5-7.1L IS USM lens, nor for the Extenders (Canon's name for teleconverters) – more details will be shared as soon as they are available.
