Best Lens for Canon R8 Mark II: 3 RF Picks for Beginners

For most new Canon EOS R8 Mark II owners, the best first lens is the Canon RF 50mm F1.8 STM, a small, inexpensive prime that opens to f/1.8. If you want one lens that zooms, choose the RF 28-70mm F2.8 IS STM as a compact f/2.8 zoom, or the RF 24-105mm F4L IS USM if travel range matters more to you than a wide aperture.

The three picks at a glance

Each lens below solves a different problem. Pick the one that matches what you shoot most, not the one with the biggest number on the box.

Lens	Best for	Why
Canon RF 50mm F1.8 STM	First prime, portraits, low light, background blur	f/1.8, about 160 g, the cheapest RF lens at launch
Canon RF 28-70mm F2.8 IS STM	One compact zoom for photo and video	f/2.8 over 28-70mm, collapsible, about 495 g
Canon RF 24-105mm F4L IS USM	Travel and general range	24-105mm at f/4 with IS, L-series build

What in-body stabilization changes for a prime without IS

The R8 Mark II adds in-body image stabilization (IBIS), which the original R8 does not have. That matters most for lenses that have no stabilization of their own. The RF 50mm F1.8 STM is one of them: its name carries no IS, unlike Canon's RF 35mm f/1.8 IS Macro STM.

On a body without IBIS, a non-IS prime leaves you relying on shutter speed alone to avoid shake. With the sensor doing the steadying, you can try slower handheld shutter speeds for still subjects: a building at dusk, a dim interior, a plate of food on a restaurant table. That pairs well with f/1.8, because you get both a wide aperture and a steadier camera working for you in low light.

Stabilization has one limit you should keep in mind. It steadies the camera, not the subject. If a person moves during a slow exposure, they blur no matter how still your hands are. For people, pets and kids, keep the shutter speed fast and let the wide aperture and ISO do the work.

The R8 vs R8 Mark II comparison covers what else changed between the two bodies, and the R8 Mark II low light settings guide covers ISO, IBIS and shutter speed together.

Canon RF 50mm F1.8 STM: the first prime to buy

A 50mm lens on a full-frame body gives an angle of view that looks natural, which is why it works for so many kinds of pictures. Canon pitches the RF 50mm F1.8 STM for portraits, everyday shots and landscapes.

What the specs give you

Canon lists a 7-blade aperture, a 0.3 m minimum focusing distance and a 0.25x maximum magnification. That close focus lets you get near food and small objects with background blur. The optical design uses 6 elements in 5 groups, and the lens measures about 40.5 mm long and weighs about 160 g.

The front ring works as a focus ring or can be set to control settings such as shutter speed or aperture. A switch on the barrel moves between "Focus" and "Control". The filter thread is 43mm.

The-Digital-Picture notes that the RF version focuses slightly closer than the older EF 50mm f/1.8 STM, giving 0.25x against 0.21x.

What reviewers found

The-Digital-Picture says the lens is not a top performer for image quality, but that it can produce high-quality images when stopped down modestly. PetaPixel describes its resolution as decent overall but a little wild in places.

At its introduction it was by far the least expensive RF lens, half the price of the next cheapest Canon RF lens. Fstoppers reviewed it at $199. That reviewer called it well built and sturdy, while noting it has no weather sealing.

Digital Camera World's reviewer wrote that it is fast enough for low light, quick to focus, and silent and smooth enough for video. Digital Camera World's verdict: if you own only one lens for an RF-mount camera, it should be this one.

The Fstoppers reviewer reported that with Eye AF set for people, the lens locked onto his subject's eye quickly and held it shot after shot. The R8 Mark II autofocus guide explains how to set up Eye AF on your camera.

Getting the most from f/1.8

Canon Ambassador Irene Rudnyk, comparing it with the far pricier RF 50mm f/1.2, said close-up portraits show little visual difference, while full-body shots show more. Her advice was to stay close to your subject or place them farther from the background.

An Fstoppers reviewer found sharpness evenly spread from f/5.6 upward, while wider apertures softened the sides of the frame unless the subject sat in the center. In practice, center your subject for wide-open portraits and stop down for scenes that need edge-to-edge detail.

The R8 Mark II background blur guide covers aperture and distance in more detail. If you are weighing focal lengths, see RF 50mm f/1.8 vs RF 35mm f/1.8.

Canon RF 28-70mm F2.8 IS STM: the compact f/2.8 zoom

If you would rather not change lenses, this zoom covers 28mm to 70mm, a standard range Canon says is frequently used for both stills and video. Its f/2.8 aperture holds across the whole zoom range, which Canon says supports handheld shooting and background blur at every focal length.

Canon kept it small with a smaller stabilization unit and a collapsible design, at about 92.2 mm long and about 495 g. That is roughly three times the weight of the 50mm prime, so it is the heavier choice, but you get a zoom with a wide aperture in exchange.

The optics use 15 elements in 12 groups, including a UD element at the front. Canon says this design gets image quality close to an L lens across the frame. For focus, Canon added a magnetic sensor to the lens's STM motor for quieter, smoother autofocus, which matters if you record video.

Stabilization in the lens and the body

Unlike the 50mm, this lens has its own optical stabilization, rated by Canon at 5.5 steps. Canon measured that figure under CIPA 2024 at 70mm on the EOS R8.

Canon says that on EOS R series cameras with in-body stabilization, the lens and camera work together for better results. On the EOS R1, Canon quotes 7.5 steps at the center and 7.0 steps at the edges. Canon's published figures cited here do not include one for the R8 Mark II, so do not assume the R1 number carries over to your camera.

For video, the zoom's quieter autofocus and its built-in stabilization make it the more flexible of the two budget picks. The R8 Mark II video settings guide covers recording settings.

Canon RF 24-105mm F4L IS USM: the travel zoom

As its name shows, this lens covers 24mm to 105mm at f/4 with image stabilization. That range reaches wider than the 28-70mm and further toward telephoto, which is what you want when you cannot swap lenses on a trip.

It is an L-series lens, and Fstoppers notes that Canon's L lenses, such as this one, are made in Japan, which helps explain why they cost more than the Malaysia-made RF 50mm F1.8 STM. The sources behind this guide include no dedicated review of this lens, so check Canon's spec sheet for weight and size before you buy.

The trade-off is aperture. The-Digital-Picture points out that a wide-aperture prime has strong advantages over narrow-aperture zoom lenses. At f/4 you get less background blur and less light than at f/2.8 or f/1.8, so in dim rooms you will lean harder on ISO and stabilization. A practical travel kit is this zoom for daytime range plus the 50mm for evenings and portraits.

How to choose your first lens

Choose the RF 50mm F1.8 STM if

You want blurred backgrounds, you shoot indoors or at night, or you are on a tight budget. It is also the best way to learn how aperture shapes a picture, because you cannot zoom your way out of a framing decision. A fixed focal length makes you move your feet, which builds good habits.

Choose the RF 28-70mm F2.8 IS STM if

You want one lens on the camera most of the time, you shoot video as well as stills, or you photograph events where you cannot step closer. You keep f/2.8 at every focal length and gain lens stabilization.

Choose the RF 24-105mm F4L IS USM if

You travel and want the widest range in one lens. Accept that f/4 gives you less blur and less light than the other two picks.

If you bought the kit lens

The RF 50mm F1.8 STM is the natural second lens next to it, because it adds a much wider aperture without adding much weight.

For more on the trade-offs, see Prime vs Zoom Lenses Explained. If your shots come out soft and you cannot tell why, the R8 Mark II blurry photos guide walks through the usual causes.

Why every pick here is a Canon RF lens

All three picks are native Canon RF lenses, so there is no adapter and no compatibility guesswork. The RF 50mm F1.8 STM, like any RF lens, is compatible with all Canon EOS R series cameras.

You may see the older EF 50mm f/1.8 STM for less money. The-Digital-Picture found the two nearly identical in specs, but notes the EF lens needs an adapter on an RF-mount camera, which adds size and cost. Its advice is plain: if you have an RF mount camera, get the RF lens. For a wider look at the system, see the Canon RF lens guide.
