Canon EOS M6 Mark II vs Samsung NX30: A Detailed Mirrorless Camera Comparison for Photography Enthusiasts

In the dynamic world of advanced mirrorless cameras, choosing the right tool can feel like navigating a labyrinth. Today, I’m diving deep into two respected models that represent distinct approaches to mirrorless photography: the Canon EOS M6 Mark II, a 2019 refresh from Canon’s APS-C lineup, and the Samsung NX30, an innovative albeit older 2014 offering from Samsung’s now discontinued mirrorless series.

Having extensively tested both cameras in varied real-world situations, I want to walk you through their nuances - handling, image quality, autofocus, video, and more - so you can figure out which camera best fits your shooting style, ambition, and budget. We’ll cover the typical shooting genres, from portraiture to wildlife, and evaluate the technical specs in context, always from the perspective of practical use rather than just raw numbers.

Design and Handling: Rangefinder Versus SLR-Style Ergonomics

Right off the bat, the Canon M6 Mark II and Samsung NX30 offer contrasting design philosophies. The M6 MII embraces a rangefinder-style mirrorless form that’s compact and minimalist - Canon’s attempt at blending portability with advanced control. This camera measures 120x70x49 mm and weighs 408 grams. The NX30 takes the SLR-style route, larger and chunkier at 127x96x58 mm and 375 grams, with a pronounced grip and traditionally shaped body.

The Canon’s slim silhouette is suited for everyday carry and travel photographers who prize discretion. Its tilting 3-inch touchscreen is intuitive but somewhat restrained in motion - helpful for composition but less flexible for vlogging or awkward angles. The Samsung’s fully articulated 3-inch AMOLED screen swings out and rotates, offering versatility for street photographers who work from low or high vantage points or selfie aficionados.

Both cameras feature built-in flashes and hot shoes for external lighting, although the Canon’s flash has a rated range of about 4.6 meters, providing respectable fill indoors or at dusk.

On the control layout, the NX30 boasts a more traditional DSLR-like arrangement with a mode dial, front and rear control dials, and several customizable buttons. The M6 Mark II, while offering good manual control with its DIGIC 8 processor backing, relies a bit more on touchscreen interaction, which might not appeal to users who prefer physical dials and precision without menu diving.

For photographers prioritizing rapid access to settings and a firmer grip, the Samsung’s SLR-style body wins. However, the Canon M6 Mark II’s sleeker form factor and lighter weight make it a more convenient travel companion.

Sensor and Image Quality: Resolution Versus Sensor Size Dynamics

Looking under the hood, both cameras use APS-C sized CMOS sensors, but this is where a significant differentiation emerges.

The Canon M6 Mark II packs a whopping 32.5-megapixels (6960x4640 resolution) with a sensor dimension of 22.3x14.9 mm and an effective sensor area of approximately 332 mm². In contrast, the Samsung NX30 employs a slightly larger APS-C sensor measuring 23.5x15.7 mm (approx. 369 mm²) but with 20 megapixels (5472x3648 resolution).

What does this mean practically?

The Canon’s higher resolution benefits photographers who want detailed landscape images or large-format prints. In my side-by-side tests, especially shooting static subjects outdoors in good light, the M6 Mark II produced images with finer texture and sharper detail, clearly discerning subtle elements like distant foliage or fine architectural lines.

However, Samsung’s NX30 sensor, albeit lower in megapixels, has slight edge in sensor area, translating to marginally better light-gathering ability per pixel. This factor contributes to somewhat cleaner images at base ISO and marginally improved dynamic range (DxOMark reports 12.4 stops for NX30 versus Canon’s untested but generally solid DIGIC 8 dynamic range).

In low-light scenarios, the Canon's higher resolution sensor tends to introduce more noise at equivalent ISO values because the pixels are packed tighter. Practically, I observed that the NX30’s images stay cleaner up to ISO 1600, making it more forgiving for night or indoor shooting without flash.

The Canon supports boosted ISOs up to 51200, while Samsung caps at 25600 native ISO with no extended options. In real-world shooting, pushing either camera beyond ISO 3200 should be considered cautiously, depending on your noise tolerance and intended use.

Both cameras employ anti-aliasing filters (to reduce moiré patterns) but this can slightly soften detail compared to cameras without such filters.

Viewfinders and LCD Screens: What You See Matters

Moving on to user interface, both cameras sport electronic viewfinders (EVFs) with near-identical resolution around 2360-2359 dots, featuring 100% coverage - a standard good enough for precise composition.

The NX30’s EVF magnification stands at 0.66x, which felt more immersive than the Canon’s unspecified magnification (likely lower). The bigger SLR-style body allows the NX30 to nestle the EVF closer to the eye, enhancing stability and comfort during extended shoots.

For rear LCDs, the Samsung’s fully articulated 3-inch AMOLED with 1036K dots provides vivid colors and deep blacks - great for reviewing images in bright sunlight or dark environments. The Canon M6 Mark II’s 3-inch 1040K dot touchscreen tilts but isn’t fully articulating, using a traditional LCD panel that’s less contrasty but still legible outdoors.

Touch responsiveness is excellent on both models, with Canon’s touchscreen implementation enabling rapid menu navigation, touch-to-focus, and exposure adjustments during live view. Samsung adds selfie-friendly articulation but the UI can feel slightly dated compared to Canon’s modern DIGIC 8 platform.

In practice, for photographers who favor quick and intuitive touch controls, Canon pulls ahead. But if you frequently shoot video or need flexible screen positioning, the NX30’s articulating AMOLED is a real advantage.

Autofocus Systems: Precision and Speed Under Pressure

Autofocus capabilities significantly influence the shooting experience across genres.

The Canon M6 Mark II uses a sophisticated hybrid autofocus system leveraging 143 phase-detection points spread across most of the frame, supplemented by contrast-detection for final sharpening. Its DIGIC 8 processor enables AI-driven tracking, face and eye detection, and continuous AF modes up to 14 frames per second - including burst shooting with continuous autofocus.

The Samsung NX30 employs a similar hybrid AF mechanism with 247 autofocus points (more than Canon), combining on-sensor phase and contrast detection. However, it maxes out at 9 frames per second continuous shooting, which is decent but somewhat dated in 2024 standards.

Practically, during wildlife and sports testing, the Canon M6 Mark II maintained faster, more reliable focus locks on moving subjects, especially in good light. For example, shooting birds in flight or kids running around a park showed fewer misfocus frames on the Canon, thanks to the refined algorithms and processing power.

Samsung’s NX30 does well in controlled conditions but tends to hunt slightly more in complex scenes or low light, illustrating the evolution in autofocus tech over the five-year gap between the cameras.

Neither camera offers animal eye autofocus, which limits fast focus for wildlife photographers somewhat, but eye detection for humans is competent on both.

Burst Shooting and Buffer: Freezing The Action

The M6 Mark II’s ability to shoot at 14fps with continuous autofocus is genuinely impressive in this price segment. I tested it shooting football matches and it captured sharp sequences of action well.

Samsung’s 9fps shooting speed is still respectable but can feel limiting when rapid-fire capture is vital for decisive moments.

Buffer depth is sufficient on both cameras to handle bursts of at least 20 RAW frames before slowing, meaning you won’t feel constrained during short action sequences.

Video Capabilities: 4K and Beyond

When it comes to videography, the Canon M6 Mark II clearly outpaces the Samsung NX30.

Canon supports 4K UHD (3840x2160) video recording at 30p with a respectable bitrate of 120 Mbps. It also offers full HD at 60p, ideal for slow-motion effects, with internal MPEG-4 H.264 codec recording. There’s a microphone input for better audio control but no headphone jack for monitoring.

Samsung NX30 maxes out at 1080p (1920x1080) at 60p. While the 3-inch fully-articulated AMOLED screen is great for video framing, the absence of 4K limits appeal for users who want higher resolution video or the ability to extract stills from 4K clips.

Neither camera offers in-body image stabilization (IBIS), so video stabilization depends on lens-based systems or electronic/manual gimbals.

Real-world use showed the Canon’s 4K footage to be pleasantly detailed with good color fidelity and low rolling shutter distortion. The NX30’s Full HD video is clean but noticeably softer, underscoring the generational technology gap.

Lens Ecosystem and Compatibility: EF-M Versus NX Mount

Another vital consideration is available lenses.

Canon’s EF-M mount features a growing native lineup of about 23 lenses, ranging from compact primes to versatile zooms, including macro and telephoto options. Though EF-M lenses aren’t as abundant as Canon’s EF or EF-S DSLR lenses, Canon supports adapters, enabling use of DSLR lenses if desired.

Samsung’s NX mount had around 32 lenses at its peak, including primes and zooms. Since Samsung exited the camera market, the lens ecosystem has shrunk, and new glass is scarce. Available lenses remain well-suited to various genres, but future proofing is limited.

Canon’s larger brand presence and ongoing development ensure better prospects for investment in glass and accessories.

Battery Life and Storage

Canon M6 Mark II uses LP-E17 batteries, rated at roughly 305 shots per charge under CIPA standards, with USB Power Delivery support allowing on-the-go charging - a boon for travel and extended outings.

Samsung NX30 takes BP1410 batteries, rated at 360 shots per charge, slightly better on paper but without USB charging.

Both cameras use a single SD/SDHC/SDXC card slot supporting UHS-I or II (Canon explicitly supports UHS-II), influencing write speeds for burst and video recording.

Connectivity: The Wireless and Wired Bridge

Wireless connectivity is a critical part of modern workflows.

Canon offers built-in Wi-Fi and Bluetooth, facilitating smooth pairing with smartphones for image transfer, remote control, and geotagging (indirectly via phone GPS apps). USB-C port supports fast data and charging.

Samsung NX30 has built-in Wi-Fi and NFC but lacks Bluetooth. Its USB 2.0 port feels dated, and the lack of smartphone integration limits remote control flexibility.

Weather Resistance and Durability

Neither camera features environmental sealing, limiting use in harsh weather conditions unless paired with protective housing.

Canon’s modern build feels robust but is not fully weatherproof, much like Samsung’s fairly solid NX30 body.

Price-to-Performance: Is Newer Always Better?

At the time of review, the Canon M6 Mark II retails around $849, while the Samsung NX30 is found for roughly $699, reflecting its used/old stock status.

Given the M6 Mark II’s advances in sensor resolution, autofocus, video, and connectivity, it offers a more future-proof, versatile package for serious enthusiasts.

The NX30 represents a good value for someone prioritizing handling layout, OLED screen quality, or who prefers DSLR ergonomics and doesn’t mind trading off 4K video or higher resolution.

Performance Across Photography Genres

Let’s pivot from specs to practical experience in specific disciplines.

Portrait Photography: Skin Tones and Bokeh Magic

Canon’s M6 Mark II with its higher resolution sensor excels at capturing detailed skin textures and smooth tonal gradations. Its advanced autofocus with eye detection helped nail sharp focus on eyes even during portrait sessions with shallow depth of field.

The slightly smaller APS-C sensor size and available fast EF-M primes yield pleasant bokeh, separating subjects from backgrounds effectively.

Samsung NX30 produces slightly softer images at 20MP resolution, but its AMOLED screen preview is excellent for evaluating exposure and focus on the fly.

If skin tone rendering and eye-detection focus matter most, Canon has the edge.

Landscape Photography: Dynamic Range and Detail Harvesting

The Canon’s 32.5MP resolution allows cropping and large prints without detail loss - a plus for landscapes.

While Samsung’s sensor has a slightly larger area, its lower resolution limits fine detail in large prints but grants marginally higher dynamic range, useful in tricky lighting.

Neither camera features weather sealing, so outdoor use in adverse conditions requires care.

Wildlife Photography: Speed and Telephoto Support

Canon’s faster autofocus, greater burst rate, and better subject tracking make it preferable for wildlife. The EF-M mount’s telephoto options, although fewer than DSLR ecosystems, suffice for casual birding and animal photography.

Samsung’s slower burst and hunting AF reduce success rates in fast-moving subjects.

Sports Photography: Tracking and Low Light Challenges

Again, Canon pulls ahead with 14fps shooting and superior phase-detect AF coverage for locking onto athletes.

NX30 remains competent for slower sports or recreational use but is less reliable in challenging lighting.

Street Photography: Discretion and Portability

Here, the Canon’s smaller size and lighter weight support longer shooting sessions unencumbered.

Samsung’s articulated OLED is handy for shooting from hip or unusual angles but the larger body can be more conspicuous.

Macro Photography: Precision and Stabilization

Neither camera offers in-body stabilization, increasing dependence on stabilized lenses or tripods.

Canon’s higher resolution allows fine detail capture of macro subjects; Samsung's AMOLED display aids manual focusing via focus peaking and magnification.

Night and Astrophotography: ISO and Exposure Controls

Samsung’s marginally cleaner low ISO noise and better dynamic range help, but Canon allows higher native and boosted ISO for flexibility.

Canon supports interval recording and built-in timelapse, valuable for astrophotography projects.

Video Work: 4K and Beyond

Canon’s 4K capability and mic input trump Samsung’s lack of 4K and limited video options.

Neither camera is designed as a professional video tool but the M6 Mark II offers broader creative possibilities.

Travel Photography: Versatility and Battery Life

Canon’s smaller form factor and USB charging are great travel perks.

Samsung lasts longer between charges but slower AF and lack of 4K video could inhibit capturing fleeting moments.

Professional Use: Workflow and Reliability

Canon’s dual card compatibility is lacking (both single slot), but RAW support, wireless transfer, and adapter support for more lenses help integrate it into workflows.

Samsung’s discontinued status limits ecosystem expansion and official support.

Final Thoughts and Recommendations

Both cameras shine in their respective niches but serve subtly different user needs.

• You are comfortable navigating a smaller ecosystem or already own Samsung NX lenses
• You want longer battery life and a camera with solid manual control feel

Methodology Note:
Throughout testing, I employed controlled studio conditions paired with on-location shooting for varied genres, shooting RAW to evaluate both JPEG out-of-camera and post-processed results in Lightroom. Autofocus was tested with both static and moving subjects in daylight and low light. Video was examined on field shoots with handheld stabilization.

My aim was to reflect the photographer’s real environment rather than synthetic benchmarks.

Ultimately, the Canon EOS M6 Mark II comes out as the better-rounded all-around performer with contemporary features, while the Samsung NX30 remains a compelling option for those who appreciate its unique handling and OLED display despite missing modern trappings.

I hope this comparison helps you cut through the noise and get hands-on clarity for your next camera choice. As always, try to handle these cameras in person if you can - ergonomics and usability are personal, critical factors beyond mere specs.

Happy shooting!
