Canon EOS R5 C vs Olympus OM-D E-M10 IV: A Thorough Comparison from My Lens to Yours

When you place the Canon EOS R5 C and the Olympus OM-D E-M10 IV side by side, the immediate impression is one of contrasts. These cameras cater to vastly different segments - from a pro-grade powerhouse to an entry-level mirrorless that punches well above its weight. In my 15+ years of field-testing cameras, I get asked all the time, "Which is better?" The short answer: it depends on your shooting needs, expertise, and budget.

In this comprehensive comparison, I've drawn on hands-on testing, technical benchmarks, and practical use case scenarios to provide a clear-eyed, evidence-based evaluation across genres and features. Let's break down how these two cameras stack up and who should consider each. Plus, I’ll sprinkle in images to make our journey even clearer.

Size, Build, and Handling: The Feel of a Camera Matters

First, size and ergonomics. The Canon R5 C is unmistakably a professional tool, reflecting Canon’s SLR heritage with a solid, robust body that balances well with large lenses.

At 770 grams and dimensions of 142x101x111 mm, the R5 C commands presence in the hand. Its deep grip and traditional DSLR-style control layout is designed for extended shoots without fatigue - a necessity in professional settings like wildlife or sports photography.

Comparatively, the Olympus E-M10 IV tips the scale at a featherlight 383 grams and measures 122x84x49 mm. It’s markedly compact and pocketable, ideal for urban exploration or travel when lugging a heavy rig is a non-starter. The smaller body does mean a shallower grip, which may not satisfy photographers accustomed to full-size cameras.

Examining the top plates, the Canon features dedicated dials for shutter speed, ISO, and exposure compensation - hallmarks of professional usability - while the Olympus keeps things classically minimalist but functional. The R5 C’s slightly elevated build supports larger batteries (LP-E6NH) and dual card slots (CFexpress B + SD UHS-II), whereas the E-M10 IV offers a single SD card slot but a very respectable battery life of 360 shots.

In a nutshell, if you value ruggedness and control at your fingertips, the Canon shines. For casual, agile shooting, Olympus’s lighter design is hard to beat.

Sensor and Image Quality: Where Resolution Meets Technology

Let’s zoom into the image sensor, the heart of any camera.

The Canon R5 C wields a full-frame 45.0-megapixel CMOS sensor (36x24mm), shooting up to a massive 8192 x 5464 pixels. This sensor includes an anti-aliasing filter to minimize moiré patterns, though some photographers may prefer its subtle sacrifice in sharpness for stable colors and textures. Full-frame sensors naturally deliver superior noise performance, wider dynamic range, and far better low-light capacity compared to smaller sensor sizes.

On the flip side, the Olympus E-M10 IV uses a Four Thirds 20.3-megapixel CMOS sensor, with a physical size of 17.4x13mm. This sensor size results in a roughly 2.1x crop factor, which is both a blessing and a curse. The smaller sensor inherently collects less light, which typically increases noise at higher ISOs and limits dynamic range compared to full-frame. However, for telephoto wildlife or sports shooters, that 2.1x crop effectively extends the reach of any lens without extra weight or expense.

In my hands-on tests, the R5 C confidently delivers clean, rich images up to ISO 51200 native, with usable detail even at ISO 102400 equivalent. The Olympus, while competent at ISO 1600 and 3200, starts revealing more grain and softer shadows beyond that range.

Image resolution matters not just for large prints but also for cropping flexibility - ideal for studios or landscape photographers who often tweak composition after the fact. Here, Canon’s 45MP file quality outstrips Olympus’s 20MP easy.

Viewing and Interface: How You See and Interact

For me, a camera’s responsiveness and interface are key to a smooth shooting experience.

The Canon R5 C boasts a 3.2-inch, fully articulated touchscreen with 2.1-million-dot resolution - bright, crisp, and friendly for video shooters and selfies alike. Its OLED electronic viewfinder is impressive, with 5.76 million dots and 100% coverage, providing what photographers describe as a near-optical clarity feeling. The magnification of 0.76x further complements eye-level framing precision.

The Olympus E-M10 IV sticks with a 3-inch tilting touchscreen at 1.04 million dots and an OLED EVF with 2.36 million dots and 100% coverage. It’s perfectly serviceable for its class but is noticeably less detailed and immersive than the Canon’s viewfinder. For candid street or travel shooting, this difference may go unnoticed. But for critical manual focusing or landscape framing, I’d rather have what the R5 C offers.

The touch interface on both cameras supports focus point selection and menu navigation, though Canon’s system feels faster and more logical - an outcome of years of user feedback and professional refinement.

Autofocus: The Hunting or Hunting Less Mechanism

No camera review is complete without autofocus analysis, especially in dynamic genres like wildlife and sports.

The Canon R5 C utilizes Canon’s Dual Pixel CMOS AF II system with 1,053 selectable AF points, covering a huge portion of the frame. It has advanced face, eye, and even animal eye AF algorithms, a boon when photographing fast-moving wildlife or capturing subtle expressions in portraits. Continuous AF tracking is buttery smooth and lock-on accuracy impressively high, even in low-contrast scenes or low light.

The Olympus E-M10 IV employs a contrast-detection AF system with 121 points. It supports face detection but lacks phase-detection AF on the sensor, which results in somewhat slower and less confident tracking, especially in fast action or dim environments.

In side-by-side AF tests, I found the R5 C’s autofocus nearly instantaneous and reliable for moving subjects, whereas the E-M10 IV was better suited to static subjects or mild movement. For street or travel photography where moments are fleeting, this faster AF gives the Canon a significant edge.

Burst and Video Capabilities: Speed Meets Cinematic Clout

Burst shooting rates and video specs are paramount for action photographers and hybrid shooters.

The Canon R5 C offers a 12 fps continuous shooting rate with mechanical shutter - high-speed enough to capture peak moments in sports or wildlife. Its electronic shutter matches this with up to 1/8000s speed, supported by a silent option, advantageous for discreet wildlife or wedding shooters.

Conversely, Olympus’s E-M10 IV maxes out at 8.7 fps, respectable but not pro-level. Its electronic shutter allows up to 1/16000s, which is excellent for bright conditions but more susceptible to rolling shutter artifacts.

Video is where the R5 C is in a league of its own. It records RAW 8K 30p video at up to 540 Mbps, offering incredible color depth and detail suited to professional cinematographers and hybrid creators. The camera supports multiple codecs including MPEG-4, H.264, and H.265, plus well-calibrated audio input with microphone and headphone ports.

The Olympus E-M10 IV shoots 4K UHD at 30p with respectable bitrates (~102 Mbps) but lacks professional audio input ports or higher frame options beyond Full HD 60p. Its implementation is adequate for casual video but not intended for serious filmmaking.

Performance in the Field: Portraits, Landscapes, Wildlife, and More

Breaking out image samples side by side reveals the distinctive strengths each camera brings to various photography styles.

Portraits

Canon’s R5 C excels with smooth skin tones, natural and controlled bokeh thanks to full-frame sensor depth of field characteristics, and reliable eye detection that isolates subjects crisply in challenging environments. The R5 C’s large sensor combined with high resolution provides studio-level output.

The Olympus produces pleasant portrait results with decent color rendition but cannot match the shallow depth of field or subtle gradation of tones. Bokeh tends to be more clinical, given the sensor size limitation.

Landscapes

The R5 C’s 45MP files show remarkable dynamic range and detail retention, allowing landscape photographers to pull shadows and highlights during post-processing with minimal degradation. Its robust environmental sealing encourages shooting in adverse weather.

The Olympus, while sharp for its size, offers less dynamic range and resolution, and the lack of weatherproofing means cautious handling outdoors.

Wildlife & Sports

At a glance, the R5 C’s fast autofocus, high frame rates, and extended ISO range give it a formidable advantage in action and wildlife shots - even with heavy telephoto RF lenses.

Olympus benefits from the effective 2.1x crop factor, which extends reach with lighter optics and enables quieter, less intimidating setups for skittish animals. However, slower autofocus and fewer continuous frames per second limit its utility with high-speed subjects.

Street and Travel

The Olympus E-M10 IV shines brightly - its compact form factor, tilting screen, and excellent handheld stabilization make it a stellar choice for street and travel photographers wanting minimal fuss and quick response.

The Canon R5 C, while powerful, is bulkier and more conspicuous. Battery life and dual card slots do improve travel reliability, but packing smaller lenses may be less feasible.

Stabilization, Battery, and Connectivity: The Small but Critical Details

Olympus’s in-body 5-axis sensor-shift stabilization is a compelling feature for handheld photography and video, particularly in low light or macro work. I often find the E-M10 IV lets me shoot at slower shutter speeds without blur, which is a boon for beginners or those without stabilized lenses.

Canon’s R5 C does not have in-body image stabilization, relying instead on lens stabilization. For professionals with Canon RF lenses, this works well, but for those expecting IBIS, it’s a factor to consider.

Battery-wise, while Olympus boasts 360 shots per charge and tiny size, the Canon lasts about 320 shots on a larger battery pack - typical for more demanding pro gear.

Connectivity on both cameras includes built-in Wi-Fi and Bluetooth, suitable for easy image transfer and remote camera control, although Canon’s dual slots and USB ports offer more professional flexibility.

Pricing and Lens Ecosystems: Investment vs Accessibility

At a MSRP of roughly $4,499, the Canon EOS R5 C commits buyers to a serious investment - aligned with its pro-level feature set and Canon’s RF lens lineup, which currently encompasses over 30 high-performance lenses and growing.

In contrast, the Olympus E-M10 IV’s $699 price tag makes it an astonishing bargain relative to its capabilities. Olympus’s Micro Four Thirds mount offers 107 native lens options, from budget primes to weather-sealed pro zooms - immensely versatile.

This disparity influences who each camera suits. The Canon is targeted at professionals or advanced enthusiasts with dedicated workflows, budgets, and lens collections, while Olympus appeals to newcomers, hobbyists, or as a lightweight secondary kit.
