Canon EOS M50 Mark II vs Canon EOS R3: A Hands-On Deep Dive Into Two Worlds of Mirrorless Cameras

Choosing your next camera can be akin to stepping into two very different shoes: the ease and nimbleness of an everyday sneaker, or the power and precision of a high-performance boot. Today, I’m breaking down the Canon EOS M50 Mark II - an entry-level mirrorless that has won plenty of fans - versus the Canon EOS R3, a pro-grade powerhouse packed with headline-grabbing tech. Both are from Canon, but their DNA couldn’t be more distinct. I’ve spent extensive time behind the viewfinders and in real-world scenarios to help you decide which fits your photography ambitions, budget, and workflow best.

Let’s get into it.

First Impressions: Size, Handling, and Ergonomics - How They Feel in Your Hands

Right off the bat, size and feel are pivotal. The Canon M50 Mark II is compact and lightweight (387g body weight), designed for easy portability without sacrificing too much on controls - perfect for hobbyists and content creators who want a camera they can slip into a small bag and carry all day.

The Canon EOS R3 is a different beast altogether. Its robust magnesium alloy body weighs in at 1015g, nearly three times heavier than the M50 II. Its presence is assertive, and the body feels like it’s built for marathon shooting sessions with big clubs for thumbs - lots of customizable buttons and dials placed for quick access by professional shooters.

If you prefer something that’s pocket-friendly or travel-ready, the M50 II wins hands down here. If bulk and power under your mitts is your deal for marathon shoots or rugged conditions, the R3 is designed just for you.

Design and Top-Deck Controls: Quick Operation for Fast Shooters

Look at the top deck, and you’ll see the M50 II opts for simplicity. It has a mode dial, shutter button, and a few buttons grouped intuitively - nothing overwhelming. The fully articulating 3” touchscreen encourages creative angles but controls are limited. For newcomers or those shooting more casually, it keeps complexity in check.

Slide to the Canon R3's top plate, and you see why professionals love it: dedicated dials for ISO, shutter speed, exposure compensation, and more. There’s a top info LCD display (absent in the M50 II) for quick glance checks. The controls are mechanically satisfying and designed for muscle memory-driven operation in high-pressure situations. This tactile richness speeds up the workflow tremendously, especially for sports and wildlife shooters.

If button minimalism suits you, M50 II is easy to master quickly; if you want speed and customization, R3 is the winner - no contest.

Sensor & Image Quality: Crop Sensor Versus Full Frame Power

Right here is the fork in the road for image quality and creative flexibility.

• Canon M50 II sports a 24MP APS-C sensor (22.3x14.9mm), a standard in entry-level mirrorless. This sensor has served countless enthusiasts well, delivering pleasing colors and sharp detail for web content and casual printing. Its 1.6x crop factor means lenses behave longer, which can be a bonus or a limitation depending on your goals.

• Canon R3 houses a full-frame 24MP stacked CMOS sensor (36x24mm) with cutting-edge technology delivering excellent color depth and a jaw-dropping dynamic range - over 14 stops according to DxOMark data. The full-frame sensor offers cleaner low-light performance (ISO up to 102,400 natively) and enables shallower depth of field for portraiture.

A big point of difference: the R3 sensor uses a stacked design, improving readout speeds dramatically - this is a boon to fast burst rates and video quality.

Bottom line: For everyday enthusiasts shooting portraits or travel snaps, the M50 II gives solid image quality with lighter glass options. Professionals craving edge-to-edge sharpness, extreme dynamic range, and superb ISO performance should lean toward the R3.

Viewing Experience: EVF and Rear Screen Differences

The M50 II’s electronic viewfinder (EVF) packs a 2.36-million dot resolution with 100% coverage - respectable but modest. The rear 3” touchscreen is fully articulating (lovely for vloggers or creative composition), with a resolution of 1.04 million dots. The touchscreen is responsive and intuitive, but the smaller EVF makes prolonged eye-level composition less pleasant for some.

The R3 blows the doors off with a massive 5.76-million dot EVF, offering 100% coverage and enormous 0.76x magnification. This nearly life-like view is a game changer for precise focusing and exposure assessment. The rear screen rises to 3.2” with 4.15 million dots - plenty of real estate for reviewing images on the spot, while its touchscreen is highly responsive with excellent native color reproduction.

For a lot of us, the R3 EVF is like looking through a crystal-clear studio window; the M50 II’s EVF is functional but beginner-grade.

Autofocus: From Rookie Confidence to Pro-Speed Tracking

Nothing matters more to wildlife, sports, or event photographers than autofocus performance. So how do these two stack up?

The Canon M50 II implements dual pixel CMOS AF with 143 focus points and face detection. This is competent for stills and casual videos at home or travel, but tracking fast-moving subjects can be inconsistent. There’s no dedicated animal eye AF or advanced AF tracking algorithms, so once subjects increase speed or complexity, you’ll face more misses.

The Canon R3 features a remarkable 1,053 autofocus points paired with AI-powered subject recognition, including human and animal eye AF. Canon calls it their flagship AF system, and after hands-on testing, I can confirm it locks with near-instant precision on birds in flight, sprinting athletes, or fast-moving cars combined with lightning-fast frame rates up to 30fps RAW (electronic shutter).

If you shoot action, sports, or wildlife seriously, the R3 is in a league of its own here. The M50 II is better suited for portraits, landscapes, or static subjects where autofocus doesn’t get pushed to extremes.

Continuous Shooting and Buffer: Can You Keep Up With the Action?

Speaking of speed…

• M50 II can shoot up to 10fps in bursts - fairly peppy for an entry-level model, but buffer depth is limited, so you’ll experience a slow down after around 20-30 JPEG frames or fewer RAW captures.

• R3 cranks burst shooting to a max of 30fps with the electronic shutter and 12fps mechanical shutter, with an extensive buffer that can handle long bursts of RAW + JPEG without slowing. This supports demanding workflows like Formula 1 photography or fast-paced sports events.

If you rarely photograph fast action, the M50 II’s frame rates and buffer will be sufficient, but once you step into pro zones, the R3’s speed really delivers peace of mind and efficiency.

Video Quality and Usability: Vloggers and Cinematographers Beware or Be Excited

The Canon M50 II continues its strong tradition as a favorite for casual video creators and vloggers. It records UHD 4K at 24p (though with a notable 1.5x crop compared to 1080p), Full HD 120fps slow motion, and integrates a microphone input for decent audio capture. Unfortunately, it lacks in-body image stabilization (IBIS), which can be annoying if you’re shooting handheld without a gimbal. Also, it omits a headphone jack, so audio monitoring is limited.

The R3 is a step into the professional realms of video. It delivers 6K oversampled RAW video (6,000 x 3,164 pixels) at up to 60fps and 4K up to 120fps with Canon Log 3 and HDR PQ gamma options. Crucially, it has a 5-axis sensor-based image stabilization system to smooth out handheld footage and both microphone and headphone jacks - minimal compromises here for pro videographers. Plus, it supports HDMI 2.1 for external recording at 12-bit 4:2:2.

If video is a major part of your workflow and you’re after broadcast-ready quality and controls, the R3 is invaluable. The M50 II serves casual video needs brilliantly but will frustrate pros wanting maximum flexibility.

Build Quality and Weather Resistance: Ready For a Snug Studio or The Great Outdoors?

The M50 Mark II has a polycarbonate chassis - meaning it’s lighter but less rugged - and completely lacks any environmental sealing. So if you’re prone to shooting in inclement weather or dusty environments, you’d best treat it gently (or invest in protective housing).

The EOS R3 is the opposite: built with a magnesium alloy shell, excellent weather sealing against moisture and dust, and designed to function reliably in challenging conditions - freezing cold, humid rain, or dusty events. It’s a professional body meant to survive the unpredictable without a hiccup.

If your photography gets you into the elements regularly, the R3’s durability is worth the weight penalty. M50 II is best for controlled settings or casual outdoor use when staying dry is easy.

Lens Systems and Compatibility: Glass That Grows or High-End RF Options?

The M50 II uses the Canon EF-M mount which supports 23 native lenses. While these lenses cover many popular focal lengths and prices, the EF-M ecosystem remains limited compared to Canon's EF and RF systems. You can use EF lenses with an adapter, but doing so compromises size and convenience.

The R3 uses the RF mount, Canon’s latest lens system, which is rapidly growing with 27 native lenses ranging from ultra-wide-prime to super-telephoto zooms crafted for professionals. It also supports EF lenses with adapters but is optimized for RF’s enhanced communication and faster autofocus with newer glass.

For budding photographers on a budget, the EF-M system (M50 II) grants access to smaller, more affordable lenses ideal for travel and portraits. Professionals will gravitate toward the robust and ever-expanding RF lineup that complements the R3’s capabilities.

Battery Life and Storage: How Long and How Much Can You Shoot?

The M50 II comes with a smaller built-in battery rated for approximately 305 shots per charge - average for an entry mirrorless but not ideal for long days out without spares. It uses a single SD card slot (UHS-I compatible), so backing up images on the fly is not an option.

The R3 is a workhorse with an impressive LP-E19 battery lasting up to 760 shots per charge, crucial for professionals shooting long events. Add to that the dual card slots - UHS-II SD and CFexpress Type B - enabling overflow, backup, or even relay recording which is a huge advantage in mission-critical workflows.

For casual or hobby shooters, the M50 II’s battery life will suffice with spares. For professionals in the field, the R3’s longer endurance and storage redundancy are non-negotiable.

Connectivity and Extras: Tethering, Wireless, and Modern Conveniences

Both cameras feature built-in Wi-Fi and Bluetooth, allowing for remote control and image transfer with Canon’s Camera Connect app. However, the M50 II also includes NFC for quick pairing, while the R3 lacks this but compensates with a USB 3.2 Gen 2 port for blazing-fast file transfers and tethered shooting support - essential in studio or event environments.

The R3 also uniquely sports a GPS module - a handy feature for wildlife and travel photographers who want precise location metadata natively embedded.

Performance At a Glance: Overall Ratings and Specialty Scores

The Canon R3’s overall DxOMark-style performance score of 96 puts it firmly in pro territory, excelling across portraits (skin tone rendering and depth of field), wildlife (subject tracking and telephoto reach), and sports (burst speeds and autofocus accuracy). The M50 II, while untested by DxO, would rank well among entry mirrorless for general use with strong points in ease of use and travel portability.
