Canon PowerShot SX120 IS vs. SX30 IS: An In-Depth Comparative Review for Photography Enthusiasts

When diving into the compact and bridge camera world, the Canon PowerShot SX series represents a compelling blend of portability, zoom reach, and affordability. Today, we pit two popular models from Canon’s superzoom lineage against each other: the Canon PowerShot SX120 IS, a compact introduced in 2009 aimed at casual shooters; and the bulkier, feature-rich SX30 IS, released just a year later in 2010, catering more towards enthusiasts seeking versatility without going full DSLR. Through meticulous hands-on testing, technical analysis, and real-world use cases across multiple photography genres, I’ll help you make an informed choice between these two power zoom cameras.

First Impressions: Size, Design, and Handling

Before getting into specs and image quality, it’s crucial to discuss how these cameras feel in hand - ergonomics can make or break the shooting experience, especially outside of a studio environment.

The Canon SX120 IS is unambiguously a “compact” in this class, weighing a mere 285g and measuring 111×71×45 mm. It’s pocketable for larger coat pockets, and its fixed lens (36-360mm equivalent) sits flush with the body when retracted. This simplicity lends itself well to casual street photography or travel, where nimbleness counts.

Contrast that with the SX30 IS, weighing in at 601g - more than twice the SX120’s heft - and sporting a bridge-style “SLR look” body (123×92×108 mm). It occupies a more significant physical and pocket footprint but offers a more substantial grip and extensive manual controls laid out in a DSLR-esque fashion.

From above, the SX30’s dedicated dials and buttons confound none of us who appreciate tactile control over complex menu diving. The SX120’s sleeker shell is simpler but limits rapid adjustments, something to note for on-the-fly shooting.

Verdict: If you prize a lightweight, pocket-friendly camera for spontaneous shots, SX120 wins. For those who want a more serious grip and control layout - especially if you often shoot with one eye in the electronic viewfinder - SX30 is the better companion.

Sensor Tech and Image Quality: CCD at Work

Both cameras employ Canon’s now-aging 1/2.5” and 1/2.3” CCD sensors, with the SX30’s marginally larger at 28.07 mm² versus SX120’s 24.74 mm². This difference might seem trivial, but it offers a small advantage in gathering light and resolving detail.

Furthermore, the SX30 IS packs a 14-megapixel resolution compared to the SX120’s 10 MP - in theory, promising slightly crisper images and more cropping freedom. Both feature an antialiasing filter to curtail moiré patterns but at a minor cost to ultimate sharpness.

In practice, I tested both cameras side-by-side across ISO ranges (80-1600 native) and typical photography situations:

• Color Rendition: The SX30 IS delivers richer, more nuanced colors thanks to its advanced DIGIC 4 processor paired with higher pixel density. Skin tones in portraiture appear more natural without oversaturation, while the SX120 sometimes veers slightly cooler or washed out under mixed lighting.

• Noise and Low Light: Both cameras show CCD noise characteristics: gradual grain buildup noticeable at ISO 400, and somewhat aggressive noise reduction that blurs fine textures at higher ISOs. But the SX30’s slightly larger sensor coupled with its DIGIC 4 handled low-light scenes better, maintaining detail with less color noise.

• Dynamic Range: Both cameras struggle with dynamic range compared to contemporary CMOS sensors, with blocked shadows and clipped highlights in high-contrast outdoor scenes. The SX30’s larger sensor and better processing afford marginally more highlight recovery.

Practical takeaway: For casual web and print use up to 8x10 inches, either sensor suffices, but the SX30 IS notably inches ahead in image quality when shooting in variable light.

Viewing and Composing: Screen and Viewfinder Usability

One area where camera usability shines is the rear LCD and viewfinder setup.

• SX120 IS: Its 3-inch screen is fixed (non-articulated) with a relatively low 230k-dot resolution, offering a bright but modest display. No viewfinder exists, meaning bright outdoor framing can be frustrating in sunlight.

• SX30 IS: The 2.7-inch screen is fully articulated - a boon for shooting at odd angles and video use - and shares the same resolution. Meanwhile, the SX30’s electronic viewfinder provides significant compositional flexibility, particularly in bright conditions or when steadiness is required.

Having used both for street and wildlife photography, the SX30’s EVF cuts down on glare issues and gives immediate feedback for framing and exposure. For casual snaps, the SX120’s bigger screen might occasionally feel more comfortable, but the articulated nature of the SX30’s display ultimately wins in versatility.

Autofocus and Shooting Speed: Tracking Tough Subjects

Both cameras rely on contrast-detection AF systems, lacking the speed and precision of more modern hybrid or phase-detection AF. However, there are distinct disparities:

• SX120 IS: Offers only single AF mode with center weighting and no continuous autofocus or tracking. This makes it suitable only for static subjects or deliberate, slow shooting.

• SX30 IS: Although still contrast-detection, supports multi-area AF with 9 focus points, enabling more flexibility in composing off-center subjects. However, continuous AF and face detection are absent, limiting performance on fast action.

In burst rate, both cameras offer 1 fps continuous shooting - painfully slow by today’s standards. Sports or wildlife photographers wanting high-speed shooting will be frustrated, but the SX30 IS’s longer lens reach and multi-area AF make it somewhat more capable for moderate action capture.

Lens Performance and Zoom Versatility

The lenses are firm fixtures but deserve close scrutiny given the different zoom ranges and apertures:

• SX120 IS: 10x zoom covering 36-360mm equivalent, max aperture F2.8-4.3, and an impressive macro close-focus at 1cm. The bright aperture is advantageous in lower light and offers more creaminess in background blur at the wide end.

• SX30 IS: 35x zoom spanning 24-840 mm equivalent, aperture F2.7-5.8, and close-focus starting at 0 cm (literally from the front of the lens). This flexibility allows capturing everything from wide landscapes to distant wildlife without swapping gear.

Image quality across zooms reveals sharper results in the SX30, thanks to more optical elements and Canon’s stepping motors for zoom and focus - albeit at the expense of a slower aperture at the telephoto end, which requires good light or higher ISO.

In macro photography, while the SX30’s claims of 0cm focusing point create some creative possibility, the SX120’s 1cm range delivers more consistent close-up sharpness and less distortion.

Battery Life and Storage

The SX120’s reliance on two AA batteries is a double-edged sword. While AA cells are universally available, their battery life is limited, particularly if using alkaline vs. NiMH rechargeables. This factor requires carrying spare batteries or switching to rechargeables for extended outings.

The SX30 IS’s proprietary NB-7L lithium-ion battery allows longer shooting mileage and faster recharge, more aligned with enthusiast needs. You also get a built-in flash with longer effective range (6.8 m vs 3 m on SX120), plus an external flash shoe - a rarity in its price tier - adding creative lighting options.

Both cameras accept SD/SDHC cards, but the SX30’s support extends to SDXC, allowing future-proof storage of larger RAW shots if Canon had offered raw on this model (spoiler alert: both cameras do not support RAW).

Video Shooting Capabilities

Video on these cameras is rudimentary compared to today’s standards but worth mentioning for hybrid shooters.

• SX120 IS: Tops out at 640×480 resolution at 30fps, recorded in Motion JPEG. The lack of external mic, zoom or focus control during recording, and low resolution make video more “snap” oriented than serious.

• SX30 IS: Offers HD-ready 1280x720 at 30fps, a solid step up for casual video sharing. It supports HDMI output for clean playback, although no microphone input limits audio quality options.

Neither camera features image stabilization optimized for video, so handheld footage can feel jittery when zoomed.
