Canon SX230 HS vs Samsung NX20: A Hands-On Comparison for Discerning Photographers

When stepping into the camera market, especially with well-established brands like Canon and Samsung, choosing the right tool for your creative vision can be a real challenge. Today, I’m diving deep into two quite distinct models from each brand’s lineup, both announced within a year of each other: the Canon PowerShot SX230 HS, a compact superzoom introduced in 2011, and Samsung’s APS-C sensor mirrorless NX20 from 2012. On paper, they appeal to quite different users - one prioritizes portability and zoom range, the other offering a more advanced mirrorless experience with interchangeable lenses and a larger sensor.

Having tested both cameras extensively, this article will guide you through every crucial aspect - from sensor technology and ergonomics to real-world imaging performance across diverse photography genres. I’ll share insights you won’t find in the usual spec sheets, including hands-on impressions that matter for practical shooting. Whether you’re after a travel buddy, a wildlife specialist, or a creative studio tool, by the end, you’ll be armed with clear recommendations tailored to your needs and budget.

Let’s get started.

Size, Handling, and Ergonomics: Big Differences, Big Impact

First impressions count, and how a camera feels in your hands can make or break your shooting experience. Canon’s SX230 HS is a compact superzoom with a body roughly 106 x 62 x 33 mm and weighing only 223 grams. Samsung’s NX20, in contrast, weighs 341 grams and is significantly larger at 122 x 90 x 40 mm, more akin to a traditional DSLR in shape and feel - but without the mirror.

If you crave pocketability and spontaneous street or travel shooting, the Canon SX230 HS’s small form factor is a huge plus. It slips into a jacket pocket easily and is extremely light, making it less fatiguing on long days out. Of course, this petite design limits physical controls and grip comfort.

The Samsung NX20 sports a deeper grip, more substantial buttons, and a body designed for more deliberate photography sessions. As you can see, its heft lends confidence when using larger lenses from its extensive NX mount lineup. I appreciated how the camera balances even with some heavier zooms attached, an important aspect for critical wildlife or portrait work.

Moving to the top view design, differences in control layout are quite visible.

The Canon prioritizes minimalism, with a simple mode dial and zoom lever riding around the shutter button. The NX20 packs dedicated dials, a customizable function button, a dedicated video record button, and exposure compensation dial - classic DSLR-style controls that many pros prefer for quick adjustments. If I were shooting fast-moving sports or wildlife, the NX20’s tactile buttons would be my ally.

In summary: for casual, on-the-go shooting, Canon’s SX230 HS edge wins. For intentional shooting, more manual control, and better grip - the NX20 takes the prize hands down.

Sensor Technology and Image Quality: Size Really Matters

Here, the battle is less close. The Canon SX230 HS features a 1/2.3” BSI CMOS sensor with a modest resolution of 12 megapixels (4000 x 3000 max image size). It’s designed mostly for convenience and zoom reach rather than image quality.

The Samsung NX20 boasts a large APS-C CMOS sensor measuring 23.5 x 15.7 mm with 20 MP resolution (5472 x 3648). This sensor is over 13 times larger in surface area than Canon’s, offering inherent advantages in dynamic range, noise control, and depth of field manipulation.

From my testing, the NX20 delivers superior overall image quality, with richer colors, smoother gradations, and excellent detail retention across ISO ranges. Canon’s SX230 HS, while surprisingly decent for its sensor size and price, shows noticeable noise above ISO 400 and limited dynamic range - expected for a small-sensor compact of its era.

Samsung’s NX20 scored a 75 on DxOMark, highlighting its robust color depth (23.4 bits), dynamic range (~13 stops at base ISO), and low light performance (ISO 785 low-light score). Unfortunately, Canon’s SX230 HS has never been tested by DxOMark, but user consensus and my samples indicate it falls well behind on these metrics.

Let me put this simply: if you value crisp, clean images and greater flexibility in post-processing, the NX20 is the way to go.

Display and Viewfinder: Framing Your Shots Effectively

In the lens world, seeing what you shoot is paramount.

Canon’s SX230 HS uses a fixed 3” PureColor II TG TFT LCD with 461k dots - decent for its class but lacking touch or articulating features.

Samsung’s NX20, however, features a 3” fully articulated OLED screen with 614k dots, offering vibrant colors, deep blacks, and excellent viewing angles. The articulated design was a boon for shooting video or challenging angles - perfect for macro, landscape, or street photography requiring low or high perspectives.

The NX20 also sports a 100% coverage electronic viewfinder with 0.7x magnification, invaluable for bright daylight composing, precise manual focusing, and immersive framing. The Canon SX230 HS lacks any viewfinder, so you’re always dependent on the rear screen.

The EVF on the NX20 proved a real asset in my outdoor shoots - the eye-level framing was steadier and less straining over long sessions. For users who find LCD screens challenging in bright sunlight, the NX20 elevates confidence.

Lens System and Zoom Range: Fixed Convenience vs Interchangeable Versatility

Canon’s SX230 HS comes with a fixed zoom lens offering a focal length range equivalent to 28-392 mm (14x zoom) with an aperture of f/3.1-5.9. It also provides a close-up macro focus starting from just 5cm, enhancing creative freedom for detail-focused shots without accessories.

Samsung’s NX20 operates with the Samsung NX lens mount and boasts a lineup of 32 lenses at launch, including primes and zooms ranging from wide-angle to super-telephoto. This is where its mirrorless design shines: the ability to switch lenses means you can tailor the optical setup to your genre - fast primes for portraits, macro lenses for flowers and insects, or telephoto zooms for wildlife.

The Canon’s fixed lens excels in convenience - you’re never changing glass, and the 14x zoom covers most situations for casual shooters and travelers.

I tried both cameras on various assignments, and the NX20’s optical flexibility was a game changer for demanding tasks like landscape panoramas with ultra-wide lenses and wildlife shoots requiring sharp long reach optics.

Autofocus Performance: Tracking the Action Without Stress

Autofocus speed and accuracy are critical when capturing decisive moments - especially in sports, wildlife, or street photography.

The Canon SX230 HS uses a 9-point AF system with contrast detection, face detection, and continuous focus modes. It’s suitable for static subjects and moderate action but struggles in low light or with fast-moving targets. Its burst shooting peaks at just 3 frames per second, limiting chances at capturing split-second sequences.

The Samsung NX20 relies on 15 contrast-detection AF points, with face detection and selective AF areas. While it lacks hybrid phase-detection focusing, the system is more accurate and faster than the Canon, especially when combined with Samsung’s responsive processor (unspecified but effective). Continuous shooting clocks in at a respectable 8 fps - well suited for sports and wildlife photography.

In my field testing, the NX20 allowed confident subject tracking and quicker lock-on, albeit with occasional hunting in dim conditions due to the lack of dedicated phase-detection AF sensors.

If you frequently shoot fast action, NX20’s autofocus system and faster burst rate give you a distinct advantage.

Shooting Experience Across Photography Genres

Now let’s cut to the chase and see how each camera fares in real-world scenarios.

Portraits: Rendering Skin and Eyes with Finesse

Portrait photography demands accurate skin tones, pleasing bokeh, and reliable eye detection AF.

The Canon SX230 HS’s small sensor and f/3.1-5.9 lens struggle to convincingly separate subject from background - bokeh is shallow and often busy. Still, color rendition is warm and flattering, as is typical for Canon’s color science. Face detection AF helps nail focus on subjects, but edge detail is limited by image processing.

The NX20, thanks to its APS-C sensor and ability to use fast primes (such as a 45mm f/1.8), produces creamy backgrounds and excellent subject isolation. Its greater resolution reveals fine facial detail without harshness.

For portraits, if smooth backgrounds and sharp eyes are priorities, NX20 wins hands down.

Landscapes: Capturing Wide Dynamic Range and Detail

Landscape shooters treasure dynamic range, resolution, and durability.

Canon’s SX230 HS provides decent resolution but limited dynamic range. The fixed lens lacks ultra-wide angles (starting at 28mm), which constrains framing options.

Samsung’s NX20, especially paired with ultra-wide primes such as the 12-24mm zoom, lets you capture expansive vistas with superb detail and contrast. Its 14-stop-ish dynamic range preserves shadow and highlight detail under challenging light.

Note, though, neither camera offers weather sealing, so I’d caution capturing landscapes in harsh wet or dusty environments without protective gear.

Wildlife and Sports: Speed, Reach, and Accuracy

While SX230 HS has respectable focal reach to 392mm equivalent, its slow maximum aperture and modest burst limits shutter speed flexibility in dim conditions and burst captures.

The NX20 through Samsung’s telephoto zooms (like 50-200mm f/4-5.6) sacrifices some ultimate reach but gains speed through faster focusing and higher frame rates. Its body accommodates heavier lenses, stabilizing quickly for handheld wildlife shots.

For rapid-fire sports or elusive animals, I gravitate to the NX20 as the more capable system.

Street Photography: Stealth and Spontaneity

Canon’s compact, quiet design makes it ideal for discrete street shooting. Its small size is almost invisible, encouraging natural candid captures.

The NX20’s larger body demands more presence but rewards the user with faster responsiveness and manual controls conducive to artistic street work.

If discretion rules your shoot, SX230 wins here. Otherwise, NX20 offers more flexibility.

Macro and Close-Up: Precision and Detail

Canon’s 5cm macro focus range is surprisingly effective for close-up details. Image stabilization helps hold handheld shots steady.

Samsung lacks specific macro prowess in the basic kit but pairs well with dedicated macro lenses for sharper results.

Night and Astro Photography: Low Light and Noise Control

Here the NX20 dominates with its ability to push ISO higher (max 12800 native) and its cleaner noise profile thanks to the larger sensor. Canon’s limited ISO 3200 max and smaller sensor mean more visible noise.

Longer shutter speeds on both are similar (Canon max 15s, Samsung max 30s), but the NX20’s greater light-gathering power makes it more suited for nightscapes and astrophotography.

Video Capabilities: Beyond Still Photography

Canon SX230 HS records Full HD 1080p video at 24 fps with H.264 compression - adequate but basic. No microphone input or advanced video features are included.

Samsung NX20 shoots Full HD at 30 fps and adds a microphone input, offering better audio recording options - a crucial detail for enthusiasts who want superior sound with their videos. The articulated OLED screen aids in framing video at unconventional angles.

Overall, video shooters will appreciate the NX20’s flexibility and audio capabilities.

Travel Photography: Versatility on the Go

Canon’s compactness, in-body stabilization, and long zoom range make it an ideal travel companion, especially if you want to avoid the hassle of lens changes.

The NX20 demands more packing but rewards with image quality leaps and creative options. Its battery life (approx 360 shots) nearly doubles that of Canon’s 210 shots, useful for longer excursions.

In my trips, I often brought both - Canon for quick snapshots and grabs, NX20 for deliberate travel photography sessions.

Professional Workflows: Reliability and Raw Formats

Only the NX20 offers raw shooting - essential for professionals seeking maximum post-processing freedom. Canon’s SX230 HS shoots exclusively in JPEG.

The NX20’s compatibility with Samsung’s lens lineup and accessories also makes it more adaptable for diverse professional assignments.
