Super-telephoto lenses are tools of specialisation. They aren’t impulse purchases, and they aren’t casual additions to a kit. When you commit to 800mm, you’re committing to a very specific way of working — one built around distance, patience, fieldcraft, and intentional composition.

After considerable thought and research, I purchased the Canon EF 800mm f/5.6L IS USM. This article goes beyond surface-level impressions and dives into why I chose it, how it performs technically, and why it continues to be a relevant and powerful option even in Canon’s RF era.

Riding The Canadian: Testing the Canon RF 100–300mm f/2.8L IS - on a Transcontinental Journey

Travelling from Ottawa to Vancouver Island aboard VIA Rail’s legendary transcontinental route—The Canadian—is an experience that blends nostalgia, wilderness, and sheer geographic scale. Over two weeks, I crossed the entire breadth of the country with a rare opportunity in hand: a loaned Canon RF 100–300mm f/2.8L IS, one of Canon’s fastest and most versatile telephoto zooms. What better proving ground than a journey through six provinces, endless forests, prairies, mountains, and some of Canada’s most dramatic wildlife encounters?
