4.7

$2,049as of Jun 7

The Canon RF 200-800mm F6.3-9 IS USM delivers an astonishing 800mm of reach at a price that puts serious super-telephoto wildlife photography within reach of enthusiasts. Images are sharp with clean color, the 5.5 stops of stabilization are essential at these focal lengths, and the 4x range covers everything from 200mm to 800mm. The slow aperture and considerable bulk are the trade-offs for that reach.

Strengths

— Jaw-dropping 800mm of reach at a price that was unthinkable a few years ago
— Sharp, detailed images with clean color, ample for wildlife and the moon
— 5.5 stops of image stabilization that proves crucial at such long focal lengths

Watch-outs

— Variable f/6.3-9 aperture forces high ISO in dim conditions
— Large and heavy at about 2.05kg, demanding a substantial bag
— The tripod collar lacks built-in Arca-Swiss compatibility

Ranked #5 in Best Telephoto Lenses for Canon RF

Canon RF 800mm F11 IS STM

4.5

$1,099as of Jun 7

The Canon RF 800mm F11 IS STM is a quirky but brilliant solution to a real problem: getting to 800mm without spending a fortune or breaking your back. For around $900 it delivers genuinely good sharpness and surprisingly capable autofocus in a light, retractable body. The catch is the fixed f/11 aperture, which restricts it firmly to bright conditions, and modest stabilization for the focal length.

Strengths

— Massive 800mm reach for around $900, a bargain in super-telephoto terms
— Very good center sharpness that holds up well across the frame
— Remarkably light for its reach at about 1260g, easily handholdable

Watch-outs

— Fixed f/11 aperture cannot be changed, limiting use to bright conditions
— Image stabilization is a modest 4 stops, low for an 800mm lens
— No weather sealing

How they stack up

Canon RF 200-800mm F6.3-9 IS USM

It offers the longest reach in this group by far, going to 800mm where the Canon RF 100-500mm F4.5-7.1 L IS USM stops at 500mm, and it is more flexible than the fixed Canon RF 800mm F11 IS STM. It is not as sharp or as bright as the RF 100-500mm L, and it gives up enormous light to the constant-f/2.8 Canon RF 70-200mm F2.8 L IS USM, but for pure budget reach it stands alone.

Canon RF 800mm F11 IS STM

It is the cheapest path to 800mm in this group, undercutting the zoom Canon RF 200-800mm F6.3-9 IS USM in price but giving up that lens's flexibility and slightly faster aperture for a fixed focal length and a fixed f/11. It cannot match the versatility of the Canon RF 100-500mm F4.5-7.1 L IS USM or the low-light ability of the Canon RF 70-200mm F2.8 L IS USM, and it is far slower than the budget Canon RF 100-400mm F5.6-8 IS USM, but nothing else reaches 800mm this cheaply.
