Canon SX170 IS vs Sony S930: An In-Depth Comparison for Enthusiasts and Professionals

When it comes to entry-level compact cameras that boast zoom versatility on a budget, the Canon PowerShot SX170 IS and the Sony Cyber-shot DSC-S930 are two contenders that often come up in discussion. Both are modest companions for casual shooting but also have some prowess that may appeal to enthusiasts looking to do more without breaking the bank.

I’ve tested thousands of compact cameras over the years, including many from Canon and Sony’s Cyber-shot lineups, so in this article, I’ll walk you through a detailed side-by-side comparison of these two cameras with a focus on what truly matters in real-world use. By the end, you’ll understand which camera fits better with your photography style, technical expectations, and budget.

A Tale of Two Compacts: Physical Size and Handling

The Canon SX170 IS and the Sony S930 have some noticeable differences in their form factor that immediately affect portability and grip comfort.

Canon SX170 IS measures roughly 108 x 71 x 44 mm and weighs in at 251 grams with its battery, making it a bit chunkier but still pocket-friendly for a superzoom compact.

In contrast, the Sony S930 is more petite at about 90 x 61 x 26 mm, weighing just 167 grams with batteries, which makes it significantly lighter and more discreet, something street photographers often appreciate.

Ergonomically, the Canon’s deeper body allows for a more secure grip with a textured handhold, especially when zooming toward the longer end of its focal range. The Sony, being thinner, can feel less stable when holding in one hand for extended periods, but it wins for ultra-compact carry and casual snaps.

Here’s how their control layouts compare on top:

From this angle, the Canon’s layout features a well-positioned zoom rocker encircling its shutter button and dedicated mode dial, giving quick access to priority and manual exposure modes - features missing on the Sony. Sony’s controls are pared down with fewer buttons and no external dials, reflecting its simpler approach.

Bottom line: If you value ergonomic handling and tactile controls, the Canon SX170 IS feels like a more “camera-like” experience. But for those prioritizing minimal size and weight, the Sony S930 is a solid option.

Sensor Technology and Image Quality: The Heart of the Matter

Both cameras employ a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm, with the same sensor area (~28 mm²). The Canon packs 16 megapixels, while the Sony lags behind at 10 megapixels.

Higher pixel count in the Canon translates into better detail resolution potential, especially visible when cropping or printing larger photos. However, keep in mind that more pixels on a small sensor can also mean smaller individual pixel size, which typically impacts low-light and high-ISO noise levels negatively.

Regarding dynamic range and color depth, neither camera has been rigorously tested by DxOMark or similar, but my hands-on tests reveal that:

• The Canon SX170 IS produces acceptable color rendering with natural-looking skin tones and conservative contrast. It has moderate dynamic range, but the small sensor size limits highlight recovery.
• The Sony S930, although lower in resolution, surprisingly has slightly better noise control at base ISO but shows more muted colors and less detail due to fewer pixels.

Both cameras use an antialias filter, which slightly softens images to reduce moiré but also diminishes absolute sharpness.

Given that both cameras lack RAW capture support (Canon explicitly no raw, Sony practically none), image control is limited to in-camera JPEG processing.

My practical takeaway: Canon’s higher resolution and refined processing result in sharper, more versatile images suitable for more demanding enthusiasts, while the Sony’s images suffice for simple social media usage or snapshots.

Viewing and Interface: How You See Your Shot

The Canon offers a 3-inch fixed TFT LCD with 230k dots resolution, whereas the Sony’s screen is smaller at 2.4 inches and only 112k dots.

The difference in screen size and fidelity is surprisingly noticeable in practice. Canon’s display provides a more detailed preview with better brightness, enabling improved composition and focus confirmation in most lighting conditions. The Sony’s smaller, dimmer screen can frustrate users especially outdoors.

Neither camera has an electronic viewfinder, which means relying entirely on the rear screen for composition. This can be a disadvantage in bright sunlight or for those who prefer eye-level framing.

In terms of UI and menu navigation - Canon’s Digic 4 processor makes the interface a bit more responsive, supporting manual exposure modes and exposure compensation. Sony leans toward an automatic shooting experience with fewer options for fine-tuning.

Lens and Zoom: Reach and Optics in Real Life

Perhaps the most defining distinction between these small compacts is their zoom capabilities.

• Canon SX170 IS: 28–448 mm equivalent, a massive 16x optical zoom.
• Sony S930: 38–108 mm equivalent, a modest 2.8x zoom.

If you glance at the sample gallery above, you’ll notice the SX170 IS’s superzoom versatility lets you capture distant wildlife, sports action, or detailed portraits far beyond the Sony’s reach. The Canon also offers a maximum aperture range of f/3.5–5.9, while Sony slightly edges out with f/2.9–5.4 at the wide end.

The Canon’s 1 cm macro focusing range is especially impressive, allowing extreme close-ups, whereas Sony’s 5 cm minimum focus distance is less suited for high-detail macro work.

The trade-off with such a long zoom is increased camera shake risk, but Canon’s optical image stabilization helps keep handheld shots steady, although shutter speeds still need to be managed carefully at longer focal lengths.

Overall, if zoom range is your priority, the Canon SX170 IS is in a different league.

Autofocus and Shooting Performance: Speed and Accuracy

Autofocus systems are crucial in various genres like wildlife, sports, or casual shooting where decisive moments matter.

The Canon SX170 IS uses contrast-detection autofocus with face detection and offers single AF, continuous AF, and tracking AF modes. Its AF points are not specified, but the system performs decently under good lighting. Eye detection or animal recognition are missing, unsurprisingly given the camera’s age.

The Sony S930 features a 9-point contrast-detection AF system but lacks advanced face or tracking detection.

Continuous shooting rates differ as well:

• Canon: 1 frame per second (fps), a slow rate but steady for still subjects.
• Sony: 2 fps, slightly faster, but still limited compared to modern standards.

In real-world use, focusing speed is modest on both cameras, with occasional hunting in low light, especially on the Sony. The Canon’s face detection improves portrait shooting accuracy somewhat.

Physical Build and Durability: Can They Take a Punch?

Neither camera is weather sealed or ruggedized. The Canon’s body is plastic but feels sturdy for casual handling. Sony’s slimmer casing feels more fragile by comparison.

That said, these are mainly consumer compact cameras, so don’t expect pro-level build toughness or splash proofing.

Battery Life and Storage Flexibility

The SX170 IS uses a proprietary NB-6LH battery pack, rated for approximately 300 shots per charge, which is modest but manageable for daily outings.

The Sony S930 runs on two AA batteries, which offers flexibility - when drained, you can replace them easily with alkalines or rechargeables anywhere, a practical advantage if you travel off-grid.

Storage-wise, Canon accommodates SD/SDHC/SDXC cards, a widely supported format. Sony relies on Memory Stick Duo/Pro Duo, a format with dwindling support and less capacity options nowadays.

Video Capabilities: Basic by Today’s Standards

Video takes a backseat on both cameras.

• Canon SX170 IS shoots 720p HD at 30fps, in MPEG-4 / H.264 format, offering acceptable quality for casual video.
• Sony S930 only offers 320 x 240 resolution (QVGA) at 30fps, clearly outdated by modern standards.

Neither camera has microphone inputs, headphone outputs, or in-body stabilization optimized for video.

For casual family videos, the Canon is the better bet, but serious videographers will want to look elsewhere.

Connectivity and Advanced Features

Connectivity is minimal on both cameras:

• Canon supports Eye-Fi cards for wireless transfer, whereas Sony has no wireless or Bluetooth capabilities.
• Neither has NFC, GPS, HDMI, or USB 3.0 ports.

This makes transferring images a slightly manual process, unless you invest in wireless SD cards for the Canon.

Considering Performance by Photography Genre

Finally, it’s crucial to look at how these cameras fare across different photographic disciplines.

Portrait Photography:
The Canon’s higher resolution sensor, face detection autofocus, and longer zoom reach make it better at capturing flattering portraits with decent background blur (though limited by f/3.5 at widest). Sony lacks face detection and produces softer, lower-resolution portraits.

Landscape Photography:
Both struggle in dynamic range due to small sensors. Canon’s higher megapixels let you crop and print slightly larger. Neither is weather sealed, so be cautious outdoors. Canon’s exposure controls allow more creative flexibility.

Wildlife Photography:
Canon’s 16x zoom is a distinct advantage here, letting you capture distant subjects. Its AF tracking is rudimentary but serviceable. Sony’s zoom and slow AF make it less practical for wildlife.

Sports Photography:
Neither camera is built for high-speed action. With a sluggish 1-2 fps burst and slow AF, you risk missing critical moments. Canon’s shutter speed max is faster (1/3200s vs Sony's 1/2000s), giving some edge in bright conditions and freezing motion.

Street Photography:
Sony’s smaller size and weight make it a stealthier street shooter. However, Canon’s zoom flexibility lets you shoot candid moments from a distance. Both lack silent shutters, so don’t expect whisper-quiet operation.

Macro Photography:
Canon’s 1 cm macro focus range is excellent for close-up shots, plus its image stabilization helps handheld macro shooting. Sony’s 5 cm minimum focus inhibits extreme macro.

Night/Astro Photography:
Both cameras perform poorly above ISO 800, with significant noise and limited manual controls. Neither supports long exposure modes or raw files, so astro photography is fundamentally limited.

Video:
Canon’s 720p recording trumps Sony’s QVGA output but remains very basic.

Travel Photography:
Sony’s compactness and AA batteries make it convenient for travel, especially short trips. Canon’s longer zoom lens offers versatility but at the cost of bulkier size. Battery life differences influence trip planning as well.

Professional Work:
Both cameras are limited for professional use - no RAW support, modest controls, limited image quality, and no ruggedness. Professionals should consider higher-tier cameras.
