Canon 400mm USM F5.6 L lens 10 month review

I take you through my journey with the Canon 400 mm f5.6 L lens photographing birds and animals for the last 10 months. The video explores the strengths and weaknesses of the lens and I give my summary of whether I recommend it or not. During the episode, I show the rescue of an injured great crested grebe and also try my hand at photographing World War 2 aircraft, so strap yourselves in and enjoy! #canon400mm #canon #Canoneflens
