While 24-70mm lenses are generally the workhorses of choice for a lot of photographers, many others prefer a 24-105mm for the extra reach, even if it means losing a stop of aperture. Canon shooters have a wide range of options when it comes to 24-105mm lenses, and this excellent video comparison takes a look at three of them, the EF 24-105mm f/4L IS II USM, RF 24-105mm f/4L IS USM, and the RF 24-105mm f/4-7.1 IS STM.
