Review of Canon 100-400mm II | Still worth buying in 2021?!

This is my long term #review of the #Canon #100-400mm F/4.5-5.6L IS II after almost 4 years of regular use. I talk about all the #pros & #cons I've discovered and show you some of my #best #sample #images taken with this lens. The question remains: in the current world of mirrorless cameras, is it worth #upgrading to the new #RF 100-500mm lens or stick with this one for considerably less #money? Will it produce similar #results in terms of #image #quality or fall considerably behind the new revamped #version for mirrorless systems?
