After hands-on testing hundreds of cameras over 15 years, I’ve spent significant time with these two models, examining how they perform across a wide range of photographic disciplines and real-world situations. In this comprehensive 2500-word comparison, you’ll find an expert, down-to-earth analysis that highlights both cameras’ strengths and limitations so you can make the most informed decision.

Getting to Know the Contenders: Design, Ergonomics, and Physical Handling

Before diving into specs, let’s talk physical usability. Handling and form factor dramatically influence whether a camera feels like an extension of your creativity or just a burden in your bag.

The Canon S120 measures a trim 100 x 59 x 29 mm and weighs 217 grams. The Olympus SH-3 is slightly larger and heavier at 109 x 63 x 42 mm and 271 grams. This extra bulk largely goes toward Olympus’s massive 24x optical zoom lens.

Canon S120 Ergonomics:

• Slim and pocketable with a straightforward button layout.
• 3-inch fixed TFT PureColor II touch screen with an excellent 922k dot resolution.
• No viewfinder, but the fixed screen is bright and offers good visibility in daylight.
• Button layout is minimal but intuitive - with an emphasis on quick access to manual controls and exposure compensation.
• Optically stabilized lens and DIGIC 6 processor keep things responsive.

Olympus SH-3 Ergonomics:

• Larger size offers a firmer grip and accommodates a more significant zoom lens efficiently.
• Also a 3-inch fixed screen but with only 460k dot resolution - noticeably less crisp in daylight.
• Touchscreen controls exist but feel less refined than Canon’s in my tests.
• No viewfinder, and the thicker body compromises pocketability slightly.
• Sensor-shift image stabilization compensates for lens size and focal length.

In direct handling, the S120 felt quicker to access common settings with no menu diving. The SH-3’s zoom capability demands a bit more from your ergonomics but offers undeniable flexibility. If discretion and minimal bulk top your priorities, Canon wins here. If versatility in focal length is critical and you’re willing to carry the extra weight, Olympus will serve you better.

Sensor and Image Quality: How Image Makers Differ

Sensor performance is the beating heart of any camera decision. Despite being small sensor compacts, the Canon S120 and Olympus SH-3 diverge notably in sensor size, resolution, and processing power. Let’s break it down.

Canon S120 Sensor:

• 1/1.7” BSI-CMOS sensor measuring 7.44 x 5.58 mm (41.52 mm² sensor area)
• 12 megapixels resolution (4000 x 3000 pixels)
• DIGIC 6 image processor optimized for noise reduction and dynamic range.

Olympus SH-3 Sensor:

• Smaller 1/2.3” BSI-CMOS sensor sized at 6.17 x 4.55 mm (28.07 mm²)
• Higher resolution at 16 megapixels (4608 x 3456 pixels)
• TruePic VII processor designed to balance noise and detail.

Technical Insights:

• The Canon’s larger sensor surface generally translates to better noise handling and dynamic range - two critical factors for image quality.
• While Olympus provides more pixels, higher megapixel counts on smaller sensors often mean compromises in noise levels and less light gathering per pixel.
• Canon’s DxOMark scores confirm an overall higher color depth and dynamic range, with 21.3 bits color depth and 11.9 EV of dynamic range compared to Olympus’s untested DxO scores - however, empirical tests suggest Canon retains better shadow detail and color fidelity.

Hands-On Test Observations:

• In low light, the S120’s images exhibited cleaner shadows and richer colors up to ISO 800.
• Olympus starts showing more noticeable noise and color shift halfway through ISO 400.
• In daylight and well-lit scenes, Olympus images look slightly sharper due to the higher pixel count but can feel noisier upon close inspection.
• Canon’s anti-aliasing filter produces smoother edges, preventing moiré patterns effectively - a plus for intricate patterns in textiles or foliage.

Summary:

• If image quality, especially in challenging lighting, is your priority, Canon’s sensor and processing combination has the clear edge.
• Olympus’s higher resolution on a smaller sensor is adequate for general use but won’t rival the S120’s refinement in demanding scenarios.

Autofocus and Focusing Capabilities

Autofocus performance can make or break your shooting experience, especially for dynamic and fast-moving subjects.

The Canon S120 utilizes an advanced contrast-detection AF system with nine selectable focus points, providing relatively fast and reliable focus acquisition. Its touch AF interface lets you quickly select subject points on the screen - a feature I found very convenient, especially in street and portrait photography.

In contrast, the Olympus SH-3 relies on a more basic contrast-detection system with an unspecified number of focus points, which occasionally hunts in low contrast or indoor scenes during testing. While it provides continuous AF and face detection, it does not have eye detection or animal eye AF, which is understandable given its compact class.

Practical Takeaways:

• For static subjects like landscapes or portraits, both cameras focus precisely.
• Moving subjects are easier for Canon’s S120 to track due to its more sophisticated focus point system and faster focus acquisition.
• Olympus’s big zoom makes focusing at long telephoto ends slower and less certain, especially in lower light.

Clear winner in autofocus speed and reliability: Canon S120.

Lens and Zoom: Optical Flexibility vs Brightness

The lenses on these compacts are fixed but cover different usage needs.

The S120’s lens starts impressively bright at f/1.8, ideal for low-light and shallow depth of field scenarios such as portraits or night scenes. The Olympus SH-3 lags with f/3.0 at the wide end and slower max apertures throughout the zoom range.

The Olympus’s standout is its superzoom capability, reaching 600 mm equivalent focal length - making it a versatile travel companion if you want everything from landscapes to distant wildlife. The downside is the narrower aperture resulting in more reliance on good lighting or higher ISO, which can introduce noise.

Image stabilization on both is effective, with Canon opting for optical lens-based IS, while Olympus uses sensor-shift - both of which help combat camera shake, especially important for long zoom or low shutter speeds.

Screen and User Interface: Navigating Controls and Review

Both cameras use fixed 3-inch LCD screens with touchscreen functionality but differ in resolution.

Canon’s higher 922k dot screen provides a crisp and colorful review experience. Touchscreen responsiveness is excellent, making menu navigation a breeze. The S120’s interface includes manual exposure controls, shutter/aperture priority, exposure compensation, and customizable white balance.

The Olympus SH-3’s screen is less sharp at 460k dots, and while touch control exists, menu response feels lagged compared to Canon. The SH-3 offers manual exposure but lacks shutter or aperture priority modes which can frustrate more advanced users seeking quick exposure adjustments.

The absence of viewfinders on both models is a minor limitation typical of compacts in this class but may impact shooting in bright outdoor conditions for some users.

Performance and Speed: Burst, Startup, and Responsiveness

Speed is critical in sports and wildlife photography to capture split-second moments.

Both cameras offer fast burst shooting near 12 frames per second, impressive for compacts. Canon’s top shutter speed advantages (1/15 sec minimum for slow shutter) mean easier long exposure handheld without a tripod compared to Olympus’s 1/30 sec.

Startup times are quick on both, but Canon’s DIGIC 6 processor contributes to more snappy overall responsiveness in menus, autofocus lock, and image processing.
