Canon RF 35mm F/1.8 Macro IS STM

This Canon prime appeared in 2018, making it one of the older designs in the RF range. It fits Canon RF full-frame mirrorless bodies.

A single 35mm focal length suits everyday pictures, from street scenes and food to travel details and environmental portraits. It is a natural single-lens choice for a casual day out. The f/1.8 maximum aperture is bright, and the lens also focuses very close.

The main trade-off is fixed framing, so you move yourself to change composition. It also has no weather sealing.

The lens weighs 10.8 oz (305 g) and measures 2.93 in (74.4 mm) across and 2.47 in (62.8 mm) long. Its compact body adds little bulk to a camera bag. A screw-in filter attached directly must match the 52mm thread. Consider the camera and lens together when planning a day of walking.

On full frame,35mm gives a moderately wide view. This suits street scenes, interiors and portraits that include some surroundings. Perspective follows the camera position. Moving closer makes nearby objects more prominent against the background; stepping back includes more of the scene.

The f/1.8 maximum aperture gathers plenty of light for a compact prime. It helps you keep shooting in dim rooms and at dusk without raising ISO as far. Wide open, it can soften a busy background behind a nearby subject. Depth of field becomes thin when you combine f/1.8 with close focusing, so place focus with care on small subjects. Stopping down a little brings more of a small subject into focus.

Closest focus is 0.6 ft (17 cm), measured from the sensor. Maximum magnification is 0.5x, or half life-size on the sensor. The Macro name describes its close-up role, but it does not reach 1:1 life-size reproduction. Leave room ahead of the glass and avoid shading a small subject as you move close.

Working at this scale, small shifts in camera position move the subject across the frame quickly. Steady support or a deliberate hand helps. Camera shake can show more at close distances, so the built-in stabilisation is useful here too.

Built-in image stabilisation helps counter camera shake during handheld work. It can help with slower exposures of still scenes in dim light. At close distances, small changes in camera position also alter focus, so review the important detail before taking the next picture.

The stabilisation supports the camera only. It does not freeze a moving subject, so a walking pedestrian still needs a quick enough shutter.

There is no weather sealing, so keep the lens out of rain, sea spray and heavy dust. No fluorine coating is listed; that does not rule out other coatings or make a protective filter necessary.

The optical formula uses 11 elements in nine groups and includes aspherical glass. Its shaped surfaces help correct distortion, which can bend straight building edges, and spherical aberration, which can soften detail. These corrections matter for interiors and architecture, where straight doorframes and window lines are easy to see.
