Canon RF 24mm F1.8 Macro IS STM Review

Quick Summary

The Canon RF 24mm F1.8 Macro IS STM is Canon's small, affordable wide-angle prime for the EOS R system, and it tries to do three jobs in one body: everyday wide shooting, low-light work and close-up macro. It weighs only 270 g, opens to f/1.8 and adds optical stabilisation, which is rare at this focal length. The trade-off is a focus motor tuned for smoothness rather than speed, and a price that sits closer to premium than budget. It is currently available at about ₹57,000 in India, which places it in the upper-middle band of Canon's non-L primes.

Design & Build Quality

This is one of the most pocketable lenses in the RF line-up. At 270 g and roughly 74 mm across by 63 mm long, it balances well on smaller bodies such as the EOS R8, R10 and R50, and it does not unbalance a larger full-frame body either. A camera with this lens on fits into a small sling bag, which matters for travel, street photography and daily carry around a city.

The barrel feels solid for its class, with a knurled control ring and a separate focusing ring. Canon does not list dust and moisture sealing for this model, so it is better treated as a fair-weather lens. During the monsoon, a rain cover and a dry box at home are sensible habits, as with most non-L lenses. The small 52 mm filter thread keeps filters cheap, which helps anyone who wants a UV or ND filter for video.

Focal Length & Perspective

A 24 mm view sits between a true ultra-wide and a standard lens. It is wide enough for interiors, landscapes, architecture and group shots in tight homes or restaurants, yet not so wide that faces stretch badly when you keep people away from the frame edges. For walk-around shooting in crowded markets, temples and narrow lanes, it is a very practical angle.

On an APS-C EOS R body, Canon says the view becomes roughly 38 mm, close to how the eye sees a scene. That makes this lens a natural everyday prime for R10 and R50 owners, and a wide option for full-frame owners. The same lens therefore serves two kinds of buyers well.

Low-Light Shooting & Stabilisation

The f/1.8 aperture is the main reason to choose this lens over a kit zoom. It gathers far more light than a typical f/4–6.3 zoom, so indoor family functions, evening streets and dimly lit cafés become easier without pushing ISO very high. It also allows a modest amount of background blur, though a 24 mm lens will never separate a subject as strongly as a 50 mm or 85 mm portrait lens.

Stabilisation is where this lens stands out. Canon rates it at up to 5 stops on its own and up to 6.5 stops with Coordinated Control IS on compatible bodies. In practice that means hand-held shots of still scenes at slow shutter speeds, such as a lit-up street at night or the inside of a dim old building, without a tripod. For video on bodies without in-body stabilisation, it also smooths walking shots noticeably. Moving subjects still need a faster shutter speed, so the stabiliser helps with scenes rather than action.

Macro Capability

The macro label is honest but needs context. The lens reaches 0.5x magnification, which is half life-size, and focuses as close as 14 cm. That is enough for flowers, food, jewellery, small products and textures, and it is far closer than most wide lenses allow. It is not a true 1:1 macro lens, so tiny insects and fine detail work need a dedicated macro lens.

The short focusing distance has a practical catch. At 0.5x the front of the lens is very close to the subject, which can block light and scare off small creatures. For still-life work on a table, product photos for an online business, or close-up food shots, this matters less, and the wide view lets you show the subject in its surroundings, which a longer macro lens cannot do.

Autofocus & Video

Focus is driven by a gear-type STM motor. Canon tunes it for smooth, quiet movement, which suits video because focus shifts do not jump and the motor noise is unlikely to be picked up by the camera's microphone. For vloggers and people filming family events, that is a real advantage.

For stills, STM motors are usually adequate for everyday subjects but not as quick as the faster motors in Canon's more expensive lenses. Children running around or pets at play are manageable on modern EOS R bodies with good subject tracking, but this is not a lens for fast sport. At close macro distances, focus naturally slows as it travels across a longer range, so manual focus with the dedicated ring can be quicker for careful close-ups.

Features Assessment

The control ring is genuinely useful. You can assign it to aperture, shutter speed, ISO or exposure compensation, so a setting you change often sits directly under your fingers. Many photographers set it to exposure compensation and leave it there, which speeds up shooting when light keeps changing.

The single UD element is meant to keep colour fringing under control, which matters on high-contrast edges such as tree branches against a bright sky. Canon does not publish detailed optical claims beyond that, so expectations should match a well-made compact prime rather than an L-series lens. The nine-blade aperture helps keep out-of-focus highlights rounder when you stop down a little.

Ease of Use

Setup is simple: mount it, choose the control ring function in the camera menu, and start shooting. The light weight means you are more likely to carry it every day, and the lens rarely needs special care beyond keeping the front element clean. The 52 mm filter thread makes protective filters inexpensive. Because the lens is not weather-sealed, it is worth keeping silica gel packs in your bag during humid months to avoid fungus, a common problem with lenses stored for long periods in Indian coastal cities.

Value for Money

The lens is currently available at about ₹56,999 to ₹57,699 in India, against an MRP of ₹61,495. That is a meaningful outlay for a non-L prime, and part of what you pay for is the combination of stabilisation, f/1.8 and 0.5x close focus in one small body. If you would use all three, the price is fair because you would otherwise need two lenses.

If you only want a wide angle for landscapes and travel and do not care about low light or close-ups, a cheaper wide prime or a kit zoom gives more value. For APS-C owners looking for a natural everyday prime, the lens also competes with Canon's own 35 mm f/1.8 macro option, so it is worth deciding first whether you prefer the 24 mm or 35 mm view.

Who Should Buy It?

• EOS R full-frame owners who want a light, wide prime for travel, street and interiors.
• APS-C EOS R owners looking for a near-natural everyday view with a bright aperture.
• Video creators and vloggers who need smooth, quiet focus and strong stabilisation on a small rig.
• Small sellers and food or craft photographers who shoot close-ups and want the setting in the frame.

Who Should Consider Alternatives?

• Photographers who need true 1:1 macro for insects or tiny detail should choose a dedicated macro lens.
• Those who shoot mostly portraits will get stronger background blur from a 50 mm or 85 mm prime.
• Buyers who shoot outdoors in heavy rain need a weather-sealed lens, which this one is not.
• Budget-focused buyers who rarely shoot in low light may be happier with a cheaper wide prime such as the RF 16mm F2.8 STM.
