Canon SX230 HS vs Sony DSC-S930: A Thorough Comparative Review for Discerning Photographers

Photography enthusiasts and professionals often face a challenging decision when selecting a camera in the compact superzoom or small sensor category. Today, we delve into a detailed, side-by-side comparison of two notable compacts from earlier generations: the Canon PowerShot SX230 HS and the Sony Cyber-shot DSC-S930. Both represent distinct philosophies in design and performance within small sensor compacts, released roughly two years apart.

This comparison aims to guide you through their technical merits, real-world usability, and suitability across various photographic genres. Having personally tested thousands of cameras over the past 15 years, I lean on firsthand experience, methodical lab measurements, and field trials to unearth insights that can make your buying decision crystal clear.

The Battle of the Bodies: Ergonomics and Handling

At the outset, handling often defines the experience, especially with compact cameras where space constraints demand clever ergonomics.

Canon SX230 HS sports a fairly conventional compact superzoom body measuring 106 x 62 x 33 mm and weighing 223g, whereas the Sony DSC-S930 is smaller and lighter at 90 x 61 x 26 mm and a mere 167g. This translates into a tangible difference when handheld over extended periods.

Holding the Canon, I found the grip more substantial, accommodating the average hand better and aiding steadiness during longer shoots. Its sculpted thumb rest and protruding lens barrel give it a confident feel. Sony’s S930, much more pocket-friendly in dimension, feels fragile in contrast but excels in portability - a perfect candidate for spontaneous shooting or travel where every gram counts.

The Canon's fixed lens extends noticeably on zooming, reinforcing the grip necessity, while Sony’s shorter zoom range keeps it sleek.

On control layout, the Canon adopts a more traditional step-up design with dedicated exposure mode dials and easy access to aperture/shutter controls, whereas the Sony pursues simplicity, stripping down manual override options (more on that shortly). This is evident in the top view comparison:

Canon offers a tactile mode dial, zoom rocker, and customizable buttons that give immediate photographic flexibility. Sony’s minimalistic approach, without a dedicated mode dial or external controls for aperture/shutter, might frustrate advanced users but serves casual shooters adequately.

Ergonomics takeaway: The Canon SX230 HS feels like a compact camera meant for photographers who desire manual control without sacrificing portability. The Sony S930 leans toward pure snapshot convenience.

Sensor and Image Quality: Why Size Isn’t Everything, But Matters

Both cameras cram their sensors into the typical 1/2.3-inch size class (sensor dimensions: 6.17 x 4.55 mm). Such sensors inherently limit dynamic range and noise performance compared to larger APS-C or full-frame sensors, but clever engineering and processing can make meaningful difference.

• Canon SX230 HS employs a 12-megapixel backside-illuminated CMOS (BSI-CMOS) sensor paired with Canon's DIGIC 4 processor and iSAPS technology. The BSI design improves light-gathering efficiency, especially in low light.

• Sony S930 uses a 10-megapixel CCD sensor, a type known for good color rendition but generally less adept in high ISO performance.

In practice, Canon's CMOS sensor with DIGIC 4 processing yielded cleaner images at higher ISO settings - usable up to ISO 800, with ISO 1600 serviceable for emergencies. Noise and detail loss escalated beyond that, unsurprisingly for a 1/2.3" sensor.

By contrast, the Sony’s CCD sensor produced images with slightly warmer tones but struggled materially with noise beyond ISO 400. Dynamic range was narrower, as measured by contrast retention in shadows and highlights.

The Canon’s maximum resolution of 4000 x 3000 pixels (12MP) versus the Sony’s 3648 x 2736 (10MP) translates to more room for cropping or large prints from the SX230 HS files.

Crucially, neither camera supports RAW capture - solely relying on JPEG output. For professionals or enthusiasts who demand maximum post-processing latitude, this is limiting.

In short: Canon’s SX230 HS delivers better image quality potential due to its BSI-CMOS sensor and newer processing pipeline. Sony’s S930 remains acceptable for casual use but visibly underperforms in noise and dynamic range tests.

Viewing and Interface: The Photographer's Eye

The LCD screen is the photographer’s window for composition and review in cameras lacking EVFs. The Canon SX230 HS incorporates a 3.0-inch PureColor II TG TFT LCD with a resolution of 461k dots, while the Sony S930 features a smaller 2.4-inch screen with only 112k dots.

The difference here is stark. The Canon’s bright, detailed display allows accurate framing and easier menu navigation, even in bright daylight. The Sony’s screen is comparatively small and dim, impairing precise focus checks or highlight/shadow scrutiny.

Neither model features a touchscreen or electronic viewfinder (EVF), which at their respective price points and segments is acceptable, though the absence of an EVF may frustrate users accustomed to eye-level shooting in bright environments.

Canon’s user interface presents familiar exposure control dials and menu systems with customizable buttons, adding to workflow efficiency. Sony’s limited control approach results in reliance on automatic modes, with fewer direct controls and menus, diminishing creative freedoms.

Autofocus and Shooting Performance: When Speed Matters

Autofocus systems are critical for all genres, particularly wildlife and sports.

The Canon SX230 HS boasts a 9-point AF system with face detection and continuous AF tracking. Using contrast-detection AF, it performed respectably in typical daylight conditions, with reliable focusing on human faces - a stride ahead of the Sony.

The Sony S930, sharing the same number of AF points but lacking advanced face detection or continuous AF, felt sluggish for moving subjects and occasionally hunted for focus indoors.

Burst shooting rates further emphasize their positioning: Canon manages 3 fps in continuous shooting mode, while Sony offers only 2 fps, constraining capture of fast action or wildlife sequences.

Practical takeaway: Canon’s autofocus system in the SX230 HS performs better for portraits (eye detection albeit basic), casual wildlife, or street shooting. Sony struggles with dynamic subjects.

Optical Performance and Lens Flexibility

Both cameras feature fixed zoom lenses, a compromise between versatility and size.

• Canon SX230 HS: 28-392 mm equivalent, 14x zoom, maximum aperture f/3.1-5.9
• Sony DSC-S930: 38-108 mm equivalent, 2.8x zoom, maximum aperture f/2.9-5.4

The Canon’s longer zoom caters well to travel, wildlife, and sports, letting photographers reach distant subjects. Its lens delivers decent sharpness, though image softness at maximum telephoto and weaker corner performance is noticeable - expected in this segment.

Sony’s shorter zoom with a bright f/2.9 maximum aperture at the wide end makes it better suited for indoor and low-light snaps, but the limited focal range constrains versatility.

Macro focusing is on par, with both cameras capable of focusing as close as 5 cm, suitable for casual close-ups.

Build Quality and Environmental Durability

Neither camera offers any substantial weather sealing, waterproofing, or ruggedness features. Both are standard compacts intended for everyday safe use. The Canon’s heftier build feels more robust in practice, giving confidence in pocket handling; the Sony’s plastic lightness raises caution in rough conditions.

Battery Life and Storage Considerations

The Canon SX230 HS uses a proprietary NB-5L battery pack rated for approximately 210 shots per charge under CIPA standards. This is modest, reflecting the power demands of its larger screen and processing.

The Sony S930 runs on two AA batteries, which is a double-edged sword: AA cells are globally available and easily replaced mid-trip, but few rechargeable AAs can match proprietary lithium in capacity. Battery life official numbers are missing, but field reports suggest comparable or slightly better longevity due to the dimmer screen and less processing demand.

For storage, the Canon supports modern SD/SDHC/SDXC memory cards, while the Sony relies on Memory Stick Duo/Pro Duo cards alongside internal memory security, a dated format with higher cost and less capacity.

Connectivity and Video Features

The Canon SX230 HS shines here, offering HDMI output, USB 2.0, GPS, and Eye-Fi wireless card support for image transfer and geotagging. Video recording capabilities include Full HD 1080p at 24 fps, 720p at 30 fps, and even high-speed VGA capture at 120/240 fps for slow motion.

The Sony S930, meanwhile, features basic 320 x 240 pixel video capture at 30 fps, using the Motion JPEG format and lacking HDMI or USB connectivity entirely. No wireless features or geotagging are included.

Canon’s video is usable for casual HD shooting, though limited to 24 fps, while Sony’s video quality is largely a novelty.
