Canon PowerShot SX120 IS vs Samsung NX300: A Hands-On, In-Depth Comparison

Choosing the right camera can be as personal as your photographic eye - and after testing thousands of cameras over 15 years, I know the decision boils down to your shooting style, priorities, and budget. Today, I’ll be sharing a detailed comparison of two very different models that highlight the evolution in camera technology over a few years: the Canon PowerShot SX120 IS, a 2009-era compact zoom, and the Samsung NX300, a 2013 mirrorless entry-level powerhouse. Though they may initially seem worlds apart, both have carved their niche in their time - and I’m here to help you understand how they perform, where each shines, and which might suit your photographic ambitions best.

First Impressions and Physical Handling: Size and Ergonomics

Starting where most photographers begin - how a camera feels in the hands.

The Canon SX120 IS is a compact point-and-shoot designed for casual, travel, or family photographers wanting simplicity with extended zoom reach. Its dimensions are 111 x 71 x 45 mm, weighing a modest 285 grams (including batteries). On the other hand, the Samsung NX300 is noticeably larger and heavier as an interchangeable lens mirrorless, measuring 122 x 64 x 41 mm and tipping the scales at 331 grams with battery.

What jumped out to me during hands-on use is the chunkier body of the NX300, which sits more solidly in the hand due to its more pronounced grip. This stability is a critical factor in demanding shooting situations, such as wildlife or sports photography, where steady handling can mean the difference between a keeper and a lost moment.

Conversely, the SX120 IS’s lightweight and small footprint make it a terrific “pocketable” companion, especially for street photography and travel when discretion and compactness rule. However, its slim build also means less real estate for controls, which is something I noticed as I tried to manually adjust settings on the fly.

Later, I’ll break down those controls - how intuitive and responsive they are - but for now, it’s clear this difference in body design reflects each camera’s core intentions: casual, all-in-one use for the Canon, and versatility coupled with more manual control for the Samsung.

Design Language: Control Layout and Interface

Peeling back the physical to the user interface and button placement, the differences became even clearer.

The Canon SX120 IS adheres to a straightforward control scheme, with limited physical dials and buttons for exposure modes, zoom, and flash. Its fixed lens and lack of advanced AF modes simplify the experience, a boon for beginners or those upgrading from smartphones seeking a better image quality with minimal fuss.

On the flip side, Samsung packed the NX300 with a richer control layout befitting a mirrorless system. Key among these are dedicated dials for exposure compensation and mode selection, along with a very responsive touchscreen interface enabling focus point selection and menu navigation. Having used both, I can vouch that the NX300’s tactile controls and responsive OLED touchscreen offer a markedly quicker and more refined shooting experience, especially when hunting for focus or adjusting exposure on-the-fly.

If you prize manual control and quick access to shooting settings, the NX300 delivers, whereas the SX120 IS prioritizes simplicity for casual capture. Both choices are valid, just different philosophies.

Behind the Lens: Sensor Technology and Image Quality

An area where technology leaps with time become especially apparent is sensor size and its impact on image quality.

Here's a visual comparison of their sensors:

The Canon SX120 IS uses a tiny 1/2.5-inch CCD sensor, measuring just 5.74 x 4.31 mm and sporting 10 megapixels. This was standard fare for compacts a decade ago. The small sensor limits performance in low light, dynamic range, and detail retention.

In contrast, the Samsung NX300 boasts a much larger APS-C CMOS sensor of 23.5 x 15.7 mm at 20 megapixels. APS-C sensors are a professional-grade standard, delivering cleaner images with less noise, richer colors, and more dynamic range.

In my controlled tests and field shooting, the NX300 consistently outperformed the SX120 IS in image clarity and color fidelity. At base ISO, fine detail retention was noticeably higher. Under challenging lighting (indoors or twilight), the Canon’s images started revealing noise and limited tonal gradation, while the Samsung held onto highlights and shadows much better.

If image quality, especially in low light or for prints larger than 8x10 inches, is a priority, the NX300 is a clear winner.

Screens, Viewfinders, and Live View Experience

Navigating the framing, reviewing, and menu experience ties directly into screen usability.

The Canon features a fixed 3-inch LCD with 230k-dot resolution. While decent for day-to-day framing, it’s somewhat dim and low resolution. For any kind of detailed review, such as checking focus sharpness, it falls short.

Samsung's NX300 introduces a 3.3-inch Active Matrix OLED touchscreen with 768k-dot resolution - far brighter, sharper, and more functional. The touchscreen allows intuitive tap-to-focus and menu navigation, cutting down the time taken to adjust settings mid-shoot.

Neither feature an electronic viewfinder, which can be a downside outdoors in bright sunlight or for critical framing. For photographer workflow, especially on the NX300, I found the tilting screen a boon for low or high-angle shots.

Autofocus System: Speed, Accuracy, and Modes

One of the most important aspects for active photographers lies in how well a camera keeps focus on moving subjects.

The Canon SX120 IS relies on contrast-detection AF only, with no phase detection or face/eye detection capabilities. Its single focus point and lack of tracking AF translate into slow acquisition and imprecise subject holding. Walking through a busy street with this camera, I noticed frequent hunting and missed shots, especially with moving people.

The Samsung NX300 sports a hybrid AF system combining contrast-detection with 247 phase-detection points, face detection, eye detection, and continuous AF tracking at up to 9 frames per second. As someone who often shoots wildlife and sports, this made all the difference - subjects stayed locked-in far more reliably, even in moderately dim light.

Bottom line: the NX300 is a far more capable tool for capturing fleeting action or ensuring tack-sharp portraits where focus on the eyes matters. The Canon is more suited to static subjects and patient shooting.

Lens Options and Flexibility

Lens systems are often the make-or-break for mirrorless versus compact cameras.

The Canon SX120 IS has a built-in 10x zoom lens covering the equivalent focal length range 36-360mm with an aperture of f/2.8-4.3. This makes it versatile in focal length, but fixed optics mean no swapping lenses or adding specialty glass.

The Samsung NX300 accepts Samsung NX mount lenses, with a range of 32 native lenses available from wide-angle primes to telephoto zooms, including macro, portrait, and fast apertures suited to varied shooting needs.

In practical terms, this means if you want to grow your gear over time, experiment with primes or specialized glass, the NX300 system wins handily. I personally found the ability to switch from an ultra-wide to a portrait prime invaluable for learning different genres.

Continuous Shooting and Burst Performance

For sports and action photography, frame rates and buffer depth matter.

The Canon SX120 offers a sluggish 1 fps continuous shooting, barely sufficient to capture a slow sequence.

By contrast, the NX300 delivers 9 fps with continuous AF, enabling crisp, sequential captures of athletes, wildlife, or kids at play.

While burst depth and buffer size weren’t massive on the NX300 compared to prosumer models, it still permits shooting sequences where timing is critical - a luxury the Canon cannot provide.

Low Light, ISO Performance, and Noise

Shooting in dim situations challenges sensors and processing. I shot a series indoors and at dusk with both cameras.

The SX120’s maximum ISO tops at 1600, yet image quality degrades fast above ISO 400 with visible grain and smudgy details. There’s also no RAW shooting, limiting post-processing flexibility.

Samsung’s NX300 boasts a broad ISO range up to 25,600 with usable results around ISO 3200-6400 in JPEG or RAW. Its CMOS sensor and DRIMe IV processor cleanly suppress noise while preserving detail, which makes nighttime street or event photography far more viable.

Weather Sealing and Durability

Both cameras miss out on weather sealing or rugged protections - this is important for photographers shooting outdoors in variable conditions.

Neither model is dustproof, waterproof, shockproof, or freezeproof, so care is required in the field, especially for travel or wildlife shooters.

Battery Life and Storage

The Canon uses 2 AA batteries, which translates to a lightweight, replace-anywhere convenience but fewer shots per charge (around 220 shots typical). This is a boon when traveling far from outlets.

The Samsung NX300 relies on a proprietary lithium-ion battery with rated life of about 330 shots per charge. It’s longer but requires access to charging facilities.

Both accept SD cards, though the NX300 supports SDXC for higher capacity cards.

Connectivity and Extras

Samsung edges ahead with built-in wireless connectivity and NFC for quick sharing and remote control. Canon’s SX120 has no wireless or GPS.

The NX300 supports external flashes and advanced flash modes, while the Canon offers only a small built-in flash with limited range.

Video Capabilities

While both cameras are primarily photo-focused:

• Canon SX120 delivers basic VGA video at 640x480@30fps in Motion JPEG, dated and low resolution by today’s standards.
• Samsung NX300 offers Full HD 1080p video at 30fps in H.264, providing much sharper and smoother footage with manual exposure control.

For casual family moments, the Canon’s video is a side benefit, but for any serious videography or hybrid use, the NX300 clearly wins.

Photography Genre Performance: What Fits Your Style?

I turned to my standard genre-specific tests, taking sample images to evaluate their strengths. Here’s a summary, illustrated with side-by-side galleries contrasting notable images from both cameras:

Portraits

Samsung’s larger sensor and reliable eye/face AF produce creamy bokeh backgrounds and natural skin tones. Canon’s small sensor and lens limit depth-of-field control and subject separation. Portraits also look softer and noisier, especially indoors.

Landscapes

NX300’s 20MP APS-C sensor captures fine details in textures, shadows, and highlights, ideal for prints or cropping. Canon images appear flatter, with less dynamic range and fine detail, especially when harsh sunshine or shadows occur.

Wildlife

High burst speed and accurate AF tracking make the NX300 a better choice. Canon’s slow 1 fps and no AF tracking limit wildlife shooting, leaving many shots blurry or out of frame.

Sports

NX300’s speed and AF system excel, letting you nail fast sequences with low light performance holding up. Canon is restricted to posed or very slow action.

Street

Canon’s compact size offers portability and discreteness, good for candid shots; however, lower IQ and slow AF hamper responsiveness. NX300 is bigger but offers sharper output and faster focus.

Macro

Canon’s close focusing at 1cm allows impressive macro, though image quality is limited. NX300’s access to dedicated macro lenses coupled with precise AF makes it superior.

Night / Astrophotography

NX300’s high ISO performance and RAW support empower long exposures with less noise. Canon’s small sensor and JPEG-only output struggle after sunset.

Video

For casual clips, Canon’s basic VGA output suffices, but NX300 offers professional-level 1080p recording with manual controls and better codec support.

Travel Photography

Canon’s compactness and lightweight make it a travel-friendly grab-and-go companion. NX300’s better image quality and flexibility reward a more deliberate traveler ready to carry extra gear.
