Canon RF 70-200mm F/2.8L IS USM

This Canon RF zoom covers 70–200mm on full-frame cameras. It suits portraits, weddings, sport and stage work where you stand some distance from the subject. The range lets you change framing as a person moves or an event develops.

Canon introduced it in 2019. Its f/2.8 maximum aperture stays available throughout the zoom. The main trade-offs are weight and width. A wider lens helps with large nearby groups and small rooms, while long sessions call for a plan to carry and support the camera.

The lens weighs 2 lb 5.7 oz (1070 g) without its tripod collar. It measures 5.75 in (146 mm) long when retracted and 3.54 in (89.9 mm) across. A monopod or rest can take the load during long waits. Screw-in filters must match the 77mm front thread.

At 200mm, one player or performer appears larger than at 70mm from the same position. The shorter setting includes more surroundings and helps you find moving action before tightening the framing. Leave space in the direction a player is moving. This gives the picture a sense of direction and reduces the chance of cutting off a hand or foot. How much of the frame the subject fills still depends on distance.

The maximum aperture remains f/2.8 as you zoom. You can retain that opening when framing changes, though a different part of the scene may need a different exposure. Under stage lights, f/2.8 gives more room for a faster shutter speed or lower ISO than a smaller opening.

At close portrait distances, f/2.8 can give a thin zone of sharp focus. A background far behind a person can become soft. Focus on the eye that matters most, then stop down when more of the face or another person must stay sharp.

Closest focus is 2.3 ft (70 cm) throughout the zoom, measured from the sensor. Maximum magnification reaches 0.23x at 200mm, useful for bouquets and larger details. Very small objects remain modest in the frame. Anything nearer than the minimum distance is too close to focus.

Image stabilization reduces camera shake and steadies the view at long settings. A still subject can allow a slower shutter speed. A running player or walking guest still needs enough shutter speed for their movement. Firm support remains useful for long exposures.

Dust and moisture resistance help outdoors. Use cover in persistent rain. Fluorine coating helps water and oily marks wipe away from the front glass. Remove loose grit before cleaning. The zoom lock prevents the barrel extending during transport; release it before changing focal length.

Two aspherical elements help correct distortion and spherical aberration, which can bend lines or soften detail. One also uses UD glass. That element, three further UD elements and one Super UD element help reduce coloured fringes along high-contrast edges, such as a player against bright sky.
