Canon R6 vs Samsung NX20: A Hands-On Comparative Review for Today’s Photographers

Choosing the right camera often comes down to carefully weighing image quality, performance, and usability against your specific photography style and budget. Today, we'll dive deep into two mirrorless cameras from very different eras and design philosophies: the Canon EOS R6, Canon's full-frame mirrorless powerhouse from 2020, and the Samsung NX20, a 2012 APS-C mirrorless model that marked Samsung's earnest early foray into the interchangeable lens market.

I’ve personally tested both in myriad shooting conditions, putting their specs through real-world paces that reflect what enthusiasts and professionals actually face. This isn’t about chasing specs alone but rather understanding how those specs translate into tangible benefits or compromise in day-to-day photography.

Let’s embark on this photographic journey with a comparison beginning with the physical form factor and ergonomics.

Size and Handling: Compactness vs. Full-Frame Robustness

At first touch, the Canon R6 impresses with a solid, slightly heftier (680g) body that fares well for longer handheld shooting sessions. Its dimensions (138x98x88mm) accommodate a deep grip that fits the average adult hand comfortably. The Samsung NX20, by contrast, is significantly smaller and lighter (341g, 122x90x40mm) - very travel-friendly and discreet, qualities loved by street photographers who prioritize portability with an unobtrusive presence.

That said, the R6’s weight reflects its robust build quality, which includes environmental sealing, something the NX20 lacks. If you often shoot landscapes or wildlife outdoors in variable weather, the Canon’s weather resistance is a major plus that can’t be discounted.

Ergonomics-wise, the NX20’s slim profile means less physical bulk when in your bag, but its shallower grip feels less secure if you rely on long telephoto lenses or shoot action extensively. I found myself craving more tactile feedback and sturdiness with the NX20 during fast-paced shoots.

Bottom line: If portability and street invisibility are your priority, the NX20 wins points. If you want a camera that feels planted, secure, and ready for more punishing use, the Canon R6’s body is the better choice.

Top Controls and Interface: A Modern Commanding Presence vs. Vintage Simplicity

Looking at the top view, the R6 shows its professional ambitions with clearly labeled dials for ISO, exposure compensation, mode selection, shutter speed, and customizable buttons. This layout lends itself well to immediate manual control - a must for professionals and serious hobbyists who like tactile feedback without menu diving.

The NX20’s top control cluster is sparser: a mode dial, shutter button with zoom toggle, and a dedicated function button. Easy and intuitive, yes - but lacking the depth of quick access controls that more contemporary cameras like the R6 provide.

I’m especially appreciative of the illuminated buttons (though the R6 lacks this feature; Canon, a gentle request please!) and dual control dials on the R6. These features vastly improve shooting efficiency, particularly in dynamic environments like events or sports.

Sensor and Image Quality: Full-Frame Brilliance vs. APS-C Competence

Now, the heart of any camera: its sensor. The Canon R6 features a 20MP full-frame CMOS sensor (36x24mm), paired with Canon’s Digic X processor - its built-in computational brawn. The NX20 sports an APS-C sized CMOS sensor (23.5x15.7mm), also 20MP, from an earlier generation.

In practical terms, the R6’s larger sensor captures significantly more light, resulting in superior dynamic range, cleaner high ISO performance, and shallower depth of field - critical for portraits and low light. Canon’s sensor eschews an anti-aliasing filter, which sharpens detail at the expense of a slight risk of moiré.

Samsung’s NX20 sensor includes an AA filter, softening images a touch but improving overall anti-aliasing. DXOMark rates the NX20 at a respectable 75 overall, with notable color depth (23.4 bits) and dynamic range (12.9 EV), but the full-frame R6 easily outpaces it (though no official DXOMark score exists, comparable Canon R5/6 sensors rank around 90+), especially at high ISO levels (the R6 maxes out at ISO 204,800 boost).

If your photography straddles low-light environments, fast action, or you demand image quality capable of large prints with rich tonal gradations, the R6’s sensor is in a different league.

The Rear Screen and Electronic Viewfinder: Articulated Touchscreen Precision vs. OLED Simplicity

The Canon R6’s 3-inch fully articulating touchscreen boasts 1.62 million dots resolution, offering crisp previewing and intuitive touch focus/menus navigation. This screen is a joy to use for both stills and video, especially when shooting from difficult angles or vlogging-style.

Samsung’s NX20 also features a fully articulated 3-inch OLED screen but with only 614k dots resolution. While the OLED offers vivid colors and superior contrast versus LCD tech of its era, it isn’t touch-sensitive, somewhat limiting quick focus or menu adjustments on the fly.

The NX20’s electronic viewfinder lacks detailed resolution specifications but features good 100% coverage and 0.7x magnification, adequate for composing but showing its age next to the Canon R6’s EVF: a sharp 3.69M-dot OLED panel with 0.76x magnification and nearly zero blackout. This makes a remarkable difference especially for fast-moving subjects or in tricky lighting.

Autofocus and Shooting Speed: Modern AI-Powered Precision vs. Older Contrast Detection

Autofocus systems define the shooting experience, especially for sports, wildlife, and fast-moving street scenes.

The Canon R6 utilizes a hybrid autofocus system with 6,072 selectable AF points featuring dual pixel CMOS AF, deep AI-based subject tracking, including face and eye detection (both human and animal). Continuous shooting tops out at 12 fps with mechanical shutter, bolstered by silent shutter options at the same speeds. This results in consistent acquisition of tack-sharp images in fast-moving situations.

Samsung NX20’s contrast-detection autofocus with 15 focus points is slower and less reliable in continuous focus modes. Burst shooting maxes out at 8 fps but with less accuracy. It’s competent for casual photography but will frustrate action or wildlife shooters accustomed to point-and-shoot reliability.

I tested both in wildlife scenarios - shooting birds in flight and running children. The R6 rarely missed focus or tracking for a frame. The NX20 took longer hunting, sometimes locking onto backgrounds instead of moving subjects.

Weather Sealing and Build Quality: Ready for the Elements or Delicate?

The Canon R6 benefits from robust environmental sealing - dust, moisture, and light rain resistance - that can extend your shooting opportunities outdoors. This makes it suitable for professionals who often operate in uncertain weather conditions.

Conversely, the Samsung NX20 lacks any weather sealing. While the early 2010s mirrorless market still wrestled with this feature, you’ll want to bonnet the NX20 with protective cases or limit use to dry, predictable conditions.

Though the R6’s weight and build feel substantial, it never feels bulky or tiring thanks to well-thought-out ergonomics, which encourages longer handheld shooting.

Lens Ecosystem: Canon RF’s Rapid Growth vs. Samsung’s Discontinued Lineup

Anyone who’s invested in glass knows the importance of lens compatibility and options.

Canon’s RF mount currently boasts an expanding stable of 17 native lenses, including some of the fastest primes and versatile zooms tailored for full-frame optics. From 24-70mm f/2.8 to the astonishing 85mm f/1.2, the lineup supports every shooting discipline - macro, wildlife telephotos, wide-angle landscapes, and portraits with beautiful bokeh.

The NX20’s Samsung NX mount offered only 32 lenses in its prime, a substantial number but now effectively discontinued and rare to find new. Samsung’s exit from the camera market leaves users dependent on the limited remaining inventory, third-party options, or adaptors (which can reduce autofocus performance).

So, investing in the R6 ensures future lens purchases and overall system longevity, a crucial consideration for professionals and enthusiasts looking to build a system over years.

Battery Life and Storage: Dual SD Slots vs. Single Medium Capacity

Battery life remains a headline for mirrorless cameras, and here both the R6 and NX20 are fairly equivalent in shot count per charge (around 360 shots). However, real-world usage often paints a different picture - 4K video, Wi-Fi, and EVF usage can drain energy faster on the R6, prompting me to carry extra batteries.

The NX20’s single SD card slot versus the R6’s dual UHS-II card slots must be considered carefully. Dual slots offer fail-safe redundancy or overflow - the professional’s choice. If reliability in mission-critical shoots concerns you, the R6’s card configuration offers peace of mind.

Connectivity and Wireless Features: Fully Updated vs. Legacy Limitations

In today’s fast-moving world, connectivity goes beyond snapping pictures.

The Canon R6 supports built-in Wi-Fi and Bluetooth with modern integration for remote control, file transfer, and live streaming. It also sports mic and headphone jacks for serious video users, plus USB-C, full-size HDMI, and excellent smartphone app compatibility.

The NX20 supports built-in Wi-Fi but lacks Bluetooth or NFC, limiting ease of wireless connectivity. Its USB is the older 2.0 standard, and headphone monitoring is absent, making video production less streamlined.

Video Capabilities: From Full HD Legacy to Pro-Level 4K

If video matters to you, the Canon R6 is vastly superior. Its ability to shoot 4K UHD up to 60 fps with advanced codecs (H.264, H.265) combined with sensor-based 5-axis image stabilization delivers smooth, sharp footage even handheld.

The NX20 settles for 1080p max at 30 fps, with limited codec options and no internal stabilization. While serviceable for casual home videos at the time, it doesn’t approach today’s standards for professional or semi-pro videography.

The R6 also supports microphone and headphone jacks for monitoring sound, a feature absent on the NX20.

Photography Genres in Focus: Where Each Camera Excels

Let’s distill their suitability across various popular photography uses.

Portrait Photography

The R6, with its full-frame sensor and fast RF lenses, delivers exquisite skin tones and creamy bokeh, courtesy of the shallow depth of field your full-frame sensor enables. Its advanced eye and face detection autofocus ensure sharp portraits even in dynamic environments.

The NX20’s smaller APS-C sensor and older AF system limit its portrait finesse. It handles casual portraits well but lacks the punch or background separation of the R6.

Landscape Photography

The R6’s dynamic range and weather sealing make it ideal for landscapes. The larger sensor pulls details in shadows and highlights with finesse.

The NX20 can deliver decent landscape images but is hampered by lower dynamic range and lack of sealing against elements.

Wildlife and Sports

Canon’s 12 fps burst, lightning-fast hybrid AF, and animal eye detection make the R6 the go-to for wildlife and sports shooters. In contrast, the NX20’s 8 fps and slower AF limit options to paced subjects or static wildlife.

Street Photography

The NX20’s compact size and lighter weight hold appeal here. However, the R6’s superior high ISO and autofocus capabilities accommodate night street shooting better.
