Canon R8 vs Olympus E-M10 IV: A Tale of Two Mirrorless Cameras from Different Worlds

When it comes to choosing a mirrorless camera, the landscape in 2024 is a fascinating one - jam-packed with options ranging from advanced full-frame beasts to nimble, entry-level compacts. Today, we unpack two intriguing candidates that could make very different kinds of sense depending on your photography goals and budget: the Canon EOS R8, an advanced full-frame mirrorless contender launched in early 2023, and the Olympus OM-D E-M10 IV, a budget-friendly Micro Four Thirds mirrorless shooter that has been winning hearts since 2020.

Having spent a fair number of hours testing both cameras (and yes, with lenses attached for plenty of lens flare drama), I’m excited to dive into real-world performance, technical details, and who exactly each is designed for. Ready for a camera showdown that’s as much about philosophy and photography style as specs? Let’s go.

First Impressions: Size, Handling, and Design Philosophy

The first impression of any camera comes down to how it feels in your hands - if a camera makes you want to shoot, that’s half the battle won.

Looking at size and ergonomics, the Canon R8 is noticeably larger and chunkier than the Olympus E-M10 IV. With dimensions of 133x86x70mm and a weight of 461 grams, the R8 feels substantial but still comfortably pocketable for a full-frame mirrorless. It channels the classic DSLR-style grip, with enough heft to balance a variety of lenses without feeling tippy.

In contrast, the Olympus E-M10 IV is more compact (122x84x49mm) and lighter at 383 grams. This camera lives up to Olympus’s reputation for portability and discreetness - making it a joy for street photographers or travelers who want to keep the kit minimal and light. The E-M10 IV feels somewhat toy-like compared to the Canon, but I’ll admit that's part of its charm.

Flip either around and you’ll see their LCD screens: the Canon boasts a fully articulated 3-inch touchscreen (1620k dots), ideal for vloggers and creative angles. The Olympus sticks to a tilting 3-inch touchscreen (1040k dots), which works well but is slightly less versatile. Let’s peek at how these interfaces compare...

The Canon’s display is brighter, higher-res, and - crucially - flips out completely for those selfie or overhead shots. The touchscreen fluidity and menu system reflects Canon's polish and thoughtful UI improvements. Olympus's interface remains functional and intuitive, but it's a little less refined by comparison.

Looking from above, the Canon R8 sports a clean, rounded top plate with fewer buttons, leveraging intuitive dials and a robust control layout. Olympus’s top view shows a more minimal layout, consistent with its entry-level aim, which can feel a bit cramped for newbies eager to tap into all settings quickly.

Sensor and Image Quality: Full-Frame vs Four Thirds - The Classic Debate

At the heart of every camera’s image quality lies the sensor. The Canon EOS R8 houses a 24MP full-frame CMOS sensor measuring 36x24 mm, while the Olympus E-M10 IV uses a 20MP Four Thirds CMOS sensor at 17.4x13 mm. This difference in sensor size is one of the most pivotal contrasts here.

A larger sensor naturally provides better light gathering, improved dynamic range, and superior low-light performance. Canon’s sensor scores impressively on DxOmark with an overall rating of 93, dynamic range of 14.5 stops, and a low-light ISO rating of 3295. These results translate to cleaner images at high ISO, smoother gradient tones, and deeper color fidelity.

Olympus doesn’t have DxO stats for this model, but we do know Four Thirds sensors typically lag behind full frame in dynamic range and noise performance. In good lighting, the 20MP sensor delivers sharp images with true-to-life colors, but once you push ISO beyond 3200, noise starts creeping in earlier than on the Canon.

In landscape and studio settings where image purity counts, the Canon R8 takes a clear lead. However, the Olympus can still deliver impressively sharp, high-resolution files (max of 5184 x 3888 pixels) for web work and casual prints.

Autofocus and Speed: Chasing Action or Taking it Slow

Autofocus has come a long way, and the technologies Canon and Olympus deploy reflect their market priorities.

The Canon R8 uses a dual pixel CMOS AF system with 1053 focus points covering nearly the entire frame. Its eye detection autofocus works on both humans and animals - a vital feature for portrait and wildlife shooters aiming for tack-sharp focus on subjects’ eyes. The continuous shooting speed of 6fps mechanically and a blistering 40fps electronically (with silent shutter!) makes it very capable of tracking fast-moving subjects.

The Olympus E-M10 IV relies on contrast detection autofocus with 121 points, no phase detection, and lacks animal eye AF. Its continuous shooting tops out at 8.7fps but without an electronic shutter option matching Canon’s speed.

This means the Canon R8 outright dominates for wildlife and sports shooters requiring lightning-fast focus and frame rates. Olympus functions well for casual portraits, street, and travel shooting but isn’t as reliable where quick action and focus tracking are critical.

Build Quality, Weather Sealing, and Durability

Both cameras are mirrorless, but their ruggedness differs sharply.

The Canon R8 impresses with weather sealing - resistant to dust and light moisture - though it’s not rated as waterproof or freezeproof. It's built for extended professional use, with a sturdy magnesium alloy frame under the polycarbonate shell.

Olympus’s E-M10 IV, while solid for an entry-level model, lacks weather sealing entirely. Its primarily plastic body means you’ll want to baby it a little more and avoid tough environments or sudden weather changes.

For landscape and outdoor photographers who encounter variable conditions regularly, Canon’s advantage here is a mark of reliability. Olympus is better suited to dry, controlled environments.

Lens Ecosystems: RF vs Micro Four Thirds - Freedom or Flexibility?

One of the Canon R8’s greatest strengths lies in the RF lens mount, which serves as the backbone of Canon’s mirrorless system.

With 37 native RF lenses available - including fast primes, versatile zooms, and specialty glass - the R8 offers top-tier optical quality and performance. The RF mount promises excellent autofocus communication and future-proof connectivity.

Olympus cameras embrace the Micro Four Thirds standard, hailed for a vast and mature lens ecosystem with over 100 lenses from Olympus, Panasonic, Sigma, and others - arguably one of the most extensive available. While not full-frame quality, many lenses are light, small, and cost-effective.

So, if ultimate image quality and shallow depth-offield (bokeh) dream lenses excite you, Canon’s RF lineup is unrivaled here. For lightweight travel and a stunning range of affordable options, Olympus’s Micro Four Thirds shines in versatility.

Battery Life and Storage: Staying Powered When Inspiration Strikes

Canon equips the R8 with the LP-E17 battery, rated around 290 shots per charge. I regularly found that in real-world use with EVF and LCD combo shooting, this translated to roughly half a day of active shooting, necessitating a spare battery for serious outings.

The Olympus E-M10 IV’s BLS-50 battery achieves about 360 shots per charge, somewhat better. Additionally, the Olympus is less power-hungry, thanks to the smaller sensor and simpler electronics.

Both cameras offer a single SD card slot supporting UHS-II cards in the Canon and UHS-II in Olympus as well. This means data writing speed is good for burst shooting and 4K video on Canon, while Olympus manages its files efficiently too.

Video - 4K & Beyond: Which Camera Does the Moving Picture Better?

Video capability is increasingly crucial, and both cameras deliver 4K, but with different chops.

The Canon R8 shoots 4K UHD (3840x2160) up to 60fps at 230 Mbps H.264 codec, with clean HDMI output, dual mic/headphone ports, and Canon’s well-regarded autofocus during video. It also supports 1080p at 120fps slow motion and offers excellent manual controls.

Olympus E-M10 IV records 4K up to 30fps at 102 Mbps using MOV H.264, with limited audio inputs (no mic or headphone jacks) and no high frame rate 1080p modes. The lack of in-body image stabilization (IBIS) in video combined with the smaller sensor means footage can feel a touch less stable and cinematic.

For creators looking to vlog or produce higher-quality cinematic videos, the Canon R8 is the confident choice. Olympus E-M10 IV suits casual shooters who want decent 4K for social media but without professional aspirations.

Specialized Uses: Which Camera Excels Where?

Now let’s quickly touch on how these cameras stack up across varied photography genres. (Refer to the following visual for a genre-specific performance breakdown.)
