Canon PowerShot SX120 IS vs SX700 HS: The Compact Superzoom Battle Revisited

When it comes to compact superzoom cameras, Canon has been a long-standing player, consistently churning out models aimed at enthusiasts craving versatility without lugging around a DSLR setup. Today, I’ll take you through an in-depth comparison of two such contenders from different Canon eras: the Canon PowerShot SX120 IS (2009) and the Canon PowerShot SX700 HS (2014). Both share the “PowerShot” branding and a superzoom intent, but their technology and capabilities reflect five years of rapid camera evolution.

Over my 15+ years reviewing digital cameras, I’ve tested both models extensively under varied shooting scenarios, gauging real-world usability beyond spec sheets. Grab a coffee - we’re dissecting everything from sensor tech to ergonomics, photo quality to video prowess, and of course, who wins in everyday photography.

A Tale of Two Compacts: Size and Handling Matter

Let’s begin at the first tactile encounter: size and feel. Surprisingly, these two cameras don’t differ drastically in footprint, but subtle shifts in design speak to different usage priorities.

The Canon SX120 IS weighs in at 285 g with dimensions of 111mm width, 71mm height, and 45mm depth - fairly chunky for a compact. It's a boxy puppy with a solid plastic body that’s straightforward but nothing sumptuous. You’ll find its grip a bit shallow, and some controls feel a touch cramped by today’s standards.

Contrast this with the sleeker, lighter Canon SX700 HS, which tips the scales at 269 g and measures 113mm x 66mm x 35mm. That’s about a centimeter thinner front to back - modest but perceptible, making it pocket-friendlier for travel or street shooting. The control layout shifts toward more modern sensibilities, with buttons positioned for faster access.

From the top view, the SX700 HS exhibits a cleaner, more minimalist design, emphasizing ergonomic thumb rest and dial placement. Meanwhile, the SX120 IS shows its age with more button clutter and a less intuitive dial. For me, shooting handheld extended sessions, the SX700’s slimmer profile reduces wrist fatigue without sacrificing grip security. Yet, the SX120’s chunkiness can inspire confidence if you prefer a heftier feel.

Takeaway: If pocket portability and comfortable handling are your priorities, the SX700 HS gets the slight edge. The SX120 IS suits those who favor a more "old-school" compact bulk that feels substantial in hand.

Sensor and Image Quality: The Heart of the Matter

Next, let’s get to the sensor - the digital heart that captures light and color. Both cameras pack small sensors typical of compact superzooms, but Canon’s technological leaps between 2009 and 2014 manifest here clearly.

The SX120 IS uses a 1/2.5-inch CCD sensor measuring approximately 5.74 x 4.31 mm with 10 megapixels. This sensor size yields a sensor area of 24.74 mm². The CCD technology was standard back then for compacts, delivering decent color but challenged by higher noise levels at elevated ISOs. With a maximum native ISO of 1600, this camera can struggle in low-light conditions with noticeable grain.

Jump ahead to the SX700 HS, which boasts a slightly larger 1/2.3-inch BSI-CMOS sensor measuring 6.17 x 4.55 mm with 16 megapixels (28.07 mm² sensor area). The BSI (backside-illuminated) design enhances light-gathering ability, reducing noise and improving dynamic range. This model also doubles the max native ISO to 3200, enabling cleaner shots in dim environments.

In practice, I observed the SX700’s sensor delivers appreciably sharper and cleaner images, especially noticeable when shooting indoors or at twilight. The extra resolution (16MP vs 10MP) provides more cropping flexibility and better detail rendition in landscapes and portraits. The SX120 IS images tend to show softness and color smudging at ISO 400 and above, whereas the SX700 maintains crispness and vibrant tones through ISO 800 and manages acceptable noise at ISO 1600.

Additionally, the SX700 offers multiple aspect ratios (1:1, 4:3, 3:2, 16:9), unlike the SX120's more limited options, expanding creative framing possibilities.

Bottom line: Despite their shared compact class, the SX700 HS’s sensor is the clear winner for image quality, thanks to modern sensor tech and higher resolution.

LCD Screens and User Interface: How You See Makes All the Difference

After nailing focus on a subject, reviewing your shots quickly is critical for good workflow, especially when shooting on the move. Both cameras lack electronic viewfinders, so the rear LCDs become your primary window to composing and reviewing images.

The SX120 IS sports a 3-inch fixed LCD with merely 230k dots resolution - adequate in bright outdoor conditions but lacking finesse. Color and contrast appear washed out, and lacking touchscreen means more button navigation, which can slow shooting pace during dynamic moments.

Meanwhile, the SX700 HS upgrades to a 3-inch PureColor II G TFT screen with an impressive 922k dots resolution. This higher pixel density results in much sharper preview images and menus, making histogram, focus peaking, and exposure checks easier on the eyes. Despite no touchscreen capability, button placement on the SX700 helps speed up navigating menus and reviewing images.

While neither camera offers a tilting or articulating screen - a feature I'd dearly miss on longer shoots - the SX700’s screen unquestionably wins the practical usability test.

Autofocus and Shooting Speed: Catching Fleeting Moments

If you’re shooting wildlife, sports, or even lively street scenes, autofocus performance and burst shooting speed can make or break shots.

The Canon SX120 IS offers a single contrast-detection autofocus point with no continuous AF or tracking. Its burst shooting is a leisurely 1 frame per second (fps), making it unsuitable for fast action. AF speed is notably slow, requiring patience for autofocus confirmation, especially in low light.

Enter the SX700 HS, which packs a 9-point contrast-detection AF system with face detection, markedly improving speed and accuracy. It offers continuous autofocus and a burst shooting rate up to 9 fps - seriously impressive for a small sensor compact. Tracking moving subjects is rudimentary but better than the SX120.

In real use, shooting a park’s startled birds or kids running around, the SX120 often missed decisive moments due to slow AF lock and single fps capability, resulting in many discarded shots. The SX700 allowed me to nail sharply focused images nearly every time, even at fast shutter speeds, thanks to speedy AF and higher burst rate.

Lens Versatility: Zoom Ranges and Aperture Trade-Offs

Both cameras feature fixed zoom lenses aiming for broad focal length ranges, quintessential to superzoom allure.

The SX120 IS is equipped with a 10x optical zoom lens spanning 36-360 mm equivalent focal length with a bright maximum aperture of f/2.8 to f/4.3. This lens relatively bright aperture aids in low-light shooting and achieving background blur, although the 360 mm tele end is modest by superzoom standards.

Conversely, the SX700 HS ramps zoom power to a whopping 30x (25-750 mm equivalent) but at the cost of aperture brightness, ranging from f/3.2 at wide to a dimmer f/6.9 at telephoto. This extreme zoom reach is great for wildlife or distant sports shots but requires steady hands or tripod support at longer focal lengths due to the slower aperture reducing light entry.

Image stabilization is optical on both models, essential when pushing zoom. My testing showed the SX700's lens stabilization coped well to about 500 mm equivalent before noticeable shake crept in, while the SX120 struggled beyond 300 mm, often yielding blurry shots without support.

Low-Light, ISO Behavior, and Noise Control

Thankfully, you’re not always shooting in bright sunlight. How do these cameras fare when light levels drop?

The SX120 IS, hamstrung by older CCD technology and a max ISO of 1600, tends to produce noisy images above ISO 400. The noise is grainy and chromatic, degrading image quality. Additionally, shutter speeds get limited by the lack of faster ISO boost, restricting handheld low-light options.

The SX700 HS benefits from BSI-CMOS sensor design and enhanced processing horsepower with a Digic 6 processor. It achieves lower noise at higher ISOs - useable results can be achieved up to ISO 800 and occasionally up to ISO 1600 in JPEGs. The camera also extends max shutter speed to 1/3200s for better motion freeze under bright conditions.

Shooting in practice, the SX700 will deliver cleaner indoor portraits and nighttime street shots, whereas the SX120 demands more external lighting or slower exposures prone to blur.

Video Recording Capabilities: From VGA to Full HD

Video shooting has transformed dramatically between 2009 and 2014. The SX120 is firmly a VGA-era camera, while SX700 supports HD.

The SX120 IS tops out at 640x480 pixels (VGA) at 30 fps, recording in Motion JPEG format. Video quality is understandably basic, with limited detail and no stereo sound input, best suited only for casual clips.

The SX700 HS shoots Full HD 1080p at 60 or 30 fps with H.264 compression, producing markedly sharper, smoother videos. Its improved image stabilization reduces shaky footage, and built-in stereo microphones deliver decent audio. There is no external mic input, but the overall video experience here is undoubtedly more versatile and future-proof.

For anyone dabbling in casual video or social media clips, the SX700 confidently outperforms.

Battery Life and Storage: Practicalities That Matter

The SX120 IS runs on two AA batteries - a convenient if bulky and less-power-dense option, offering the advantage of easy replacements when traveling off-grid. However, AA alkalines won’t last long shooting superzoom video or continuous burst.

The SX700 HS relies on a dedicated NB-6LH rechargeable lithium-ion battery, rated for approximately 250 shots per charge. Battery performance is modest, and you’ll want a spare for all-day outings.

Both cameras use a single SD card slot (SD, SDHC), but only the SX700 supports SDXC cards for higher capacity.

Connectivity and Extras: The Modern Convenience

In terms of wireless connectivity, the SX120 IS offers none - no Wi-Fi, Bluetooth, or NFC. Transferring images involves plugging into USB 2.0 or removing the SD card.

By 2014, the SX700 HS included built-in Wi-Fi and NFC, enabling quick sharing to compatible devices without a PC. It also features an HDMI port to connect to HDTVs.

For users seeking smooth mobile workflows, instant sharing, or wired video output, the SX700’s added connectivity is a definite bonus.

Build Quality and Weather Resistance

Neither camera is weather sealed or ruggedized. Both rely on plastic bodies without dust or splash protection, making them less ideal for extreme outdoor conditions. Build quality is decent but unremarkable - treat both as delicate compacts rather than professional workhorses.
