I have just published Episode #63 of my Wild Nature Photography Podcast. In this episode, I discuss packing and equipment for my Arctic Fox expedition in the Hornstrandir Nature Reserve in north-western Iceland as well as discuss the often maligned Canon RF 100-500mm f4.5-7.1 IS L series lens. This is a lens I was not too keen on initially based on its variable f-stop, but recent tests have made me a complete convert. This lens is a must-have for Canon wildlife photographers.
