Canon PowerShot S110 vs. SX20 IS: An In-Depth Comparison for the Discerning Photographer

When comparing two cameras from Canon’s sprawling PowerShot line - the compact S110 and the superzoom SX20 IS - you're really looking at two cameras designed around very different philosophies, despite their rather similar 12-megapixel sensor counts. Released two years apart and catering to distinct kinds of shooters, these cameras offer a fascinating lens into Canon’s early 2010s approach to versatile photography. Having spent hundreds of hours testing each myself both in the field and under controlled conditions, I’ll walk you through their critical differences, strengths, and weaknesses with an eye for what matters most to photographers today.

Size, Build, and Ergonomics: Pocket-Friendly vs. Bridge-Like Presence

Starting with physical design and handling, the S110 is a classic compact, pocketable camera designed to slip easily into your jacket or purse. Its dimensions read 99x59x27 mm and weighs a mere 198 grams. In contrast, the SX20 IS is a hefty bridge camera, sitting at 128x88x87 mm and weighing a solid 600 grams due to its larger lens and battery. This difference is evident the moment you pick them up.

The SX20’s SLR-style body lends itself well to steady grip and longer shooting sessions - a feature serious users appreciate. Its thumb rest and textured grip are comfortable, helping offset its bulk, though it's less ideal for discreet street or travel photography. Meanwhile, the S110’s minimalistic compact design lends itself well to casual shooters wanting something unobtrusive, though extended use can feel a bit cramped.

Ergonomically, the SX20 has more dedicated controls including a mode dial, zoom rocker, and buttons that provide tactile feedback - ideal for users who prefer direct access without diving into menus. The S110 embraces a minimalist approach, incorporating a 3-inch touchscreen which replaces many physical buttons but may be less satisfying for users who crave manual dials.

In short, if you prioritize portability and quick carry, S110 wins hands down. For control and comfort during prolonged use, SX20 IS is the better companion.

Sensor and Image Quality: Small Sensors, Different Outcomes

Both cameras feature 12MP sensors, but that’s where their similarities end. The S110 sports a 1/1.7-inch CMOS sensor measuring 7.44 x 5.58 mm (41.5 mm² area) with DIGIC 5 processing, while the SX20 IS relies on a smaller 1/2.3-inch CCD sensor (6.17 x 4.55 mm, 28 mm² area) backed by the older DIGIC 4 processor.

From extensive side-by-side RAW shooting, the S110 noticeably pulls ahead in image quality thanks to its CMOS sensor’s superior dynamic range (~11.2 EV vs. CCD’s more limited range) and better low-light sensitivity (ISO performance rated DxO low-light score ~168 vs. untested but known lesser CCD performance). Its sensor also reads data faster, enabling continuous shooting at 10 fps - versus a meager 1 fps on the SX20.

The smaller CCD sensor on the SX20 IS, while adequate for typical daylight snaps, struggles with higher ISO noise and dynamic range in challenging lighting conditions. The CCD's tendency toward higher noise after ISO 400 makes it less suited for low-light landscape or event shooting.

Color depth leans advantageously to the S110 (DxO color depth rating 20.6 bits) resulting in richer skin tones and more natural hues straight out of camera, essential for portrait and indoor use. The SX20's colors appear flatter and require more post-processing finesse.

Viewfinders and Screens: Sometimes It’s About What You See

The S110 lacks a dedicated viewfinder, relying instead on a 3.0-inch fixed touchscreen display with a respectable 461k-dot resolution - a rare touchscreen inclusion in its era, bringing an intuitive interface with tap-to-focus functionality. However, in bright midday conditions, glare can make composing tricky.

Conversely, the SX20 IS includes an electronic viewfinder (EVF) - though modest by today’s high-res standards - plus a 2.5-inch fully articulated screen at 230k dots. The articulated screen is invaluable for awkward angles and low shots, especially for wildlife and macro work.

While the SX20’s EVF offers eye-level stability and better visibility in harsh light, its resolution leaves something to be desired. The S110’s touchscreen, although not articulating, provides a modern, sleek shooting experience that’s invaluable for on-the-fly focus adjustment and menu navigation.

Autofocus and Shooting Speed: Catching the Action or Taking Your Time?

Autofocus is central to how these cameras perform in real-world shooting situations, especially wildlife and sports, where split-second timing matters. Here, the S110 has a noticeable edge with a 9-point contrast-detect AF system enhanced by face detection and continuous AF tracking modes. This allows reliable focus on moving subjects in live view and bursts up to 10fps, a rare speed for its class.

The SX20 IS, despite having 9 focus points matching the S110’s count, relies solely on contrast-detection AF without face detection or continuous tracking. Its single-shot AF and shutter lag result in missed opportunities during fast action.

From my fieldwork in both urban street scenes and local wildlife parks, S110’s AF was more responsive and accurate, especially on faces and eyes during portraits and kids running around. The SX20 requires patience and aims better with static or slow-moving subjects.

Lens Range and Aperture: Versatility vs. Low-Light Flexibility

One clear strength for the SX20 IS is its whopping 20x zoom (28–560mm equivalent), making it the go-to for telephoto needs such as wildlife or sports where reach is non-negotiable. Its maximum aperture of f/2.8–5.7 is excellent at the wide end for low light but narrows as you zoom in.

The S110 sports a shorter, more pocketable 5x zoom range (24–120mm equivalent) but flaunts a brighter f/2.0 aperture at the wide end - a real benefit for dim interiors, street photography, and shallow depth of field effects in portraits.

This wider aperture and shorter focal length combine to provide S110 with smoother bokeh and subject-background separation, especially useful when shooting portraits and close-ups, where creamy background blur contributes to professional image aesthetics.

Burst, Buffer, and Storage: How Fast and How Long?

Shooting speed differences chart a stark contrast. The S110 boasts continuous shooting at 10fps, ideal for capturing fleeting expressions or decisive moments in sports and street photography. Its buffer can handle approximately 7-8 RAW shots before slowing.

The SX20 IS, on the other hand, manages a paltry 1fps continuous burst - barely enough for anything but the slowest action.

Both cameras support SD/SDHC cards, but SX20 IS’s broader compatibility with MMC formats reflects its age. Battery-wise, the SX20 uses 4 AA batteries, which can be handy for travel where recharging is tough, whereas the S110’s proprietary NB-5L battery offers 200 shots per charge, necessitating extra spares for extended outings.

Video Capabilities: A Multi-Tasker or Basic Utility?

Video specs favor the S110 with Full HD 1080p recording at 24fps using H.264 compression - a capability quite advanced for a 2012 compact. This extends its versatility for travel and casual videography, although it lacks microphone inputs or advanced manual controls.

The SX20 IS caps out at 720p HD video at 30fps, which is fairly basic by today’s standards and more prone to noise due to the older sensor.

Neither camera supports 4K or advanced video features, but the S110 clearly targets hybrid shooters who want better stills and video in one compact body.

Special Features, Connectivity, and Usability Extras

The S110 includes built-in Wi-Fi, allowing image transfer without cables - an incredibly handy feature for instant sharing in the digital age. Touchscreen AF and manual exposure modes give it an edge for advanced users who want control in a petite package.

The SX20 IS lacks wireless connectivity altogether, reflective of its 2010 release. However, it counters with a fully articulating LCD and compatibility with external flashes via hot shoe, improving flexibility for creative lighting.

Neither camera boasts environmental sealing, so both require care in adverse weather. The SX20 IS is more rugged in feel due to its size, but don't expect weatherproofing.
