Canon RF 800mm f/11 IS STM

The longer-reach sibling to the RF 600mm f/11 — same budget fixed-aperture formula, extended to 800mm, and unlike the 600mm it's confirmed compatible with Canon's RF extenders for up to 1600mm effective reach. A popular affordable choice for extreme-reach wildlife and birding, and for moon or eclipse photography, where absolute focal length matters more than aperture speed or sealing.

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
