Canon PowerShot S120 vs. Ricoh GR Digital III: An Expert Hands-On Comparison for Compact Camera Enthusiasts

When it comes to small sensor compacts designed for serious photographers who also crave pocketable convenience, two models often come up in conversation: Canon’s PowerShot S120 and Ricoh’s GR Digital III. Though these cameras were launched years apart - Canon S120 in late 2013 and Ricoh GR Digital III in mid-2009 - both represent distinct philosophies of what a high-end compact camera should offer. Drawing from my extensive experience testing thousands of cameras, including rigorous side-by-side sessions with these two models, this comparison aims to provide you with a clear, practical, and trustworthy look at how these cameras perform today - both technically and in the real world.

Whether you’re a budget-conscious enthusiast, a street photographer, or a casual traveler wanting a sharp, easy-to-carry backup, I’ll help you decide which of these venerable compacts fits your style, workflow, and creative needs best.

A Tale of Two Compacts: Design, Handling, and Ergonomics

First impressions matter, especially when a camera is as tactile as a pocket camera you’ll want at hand for spontaneous moments. Both the Canon S120 and the Ricoh GR Digital III offer classic compact silhouettes, but their design philosophies differ subtly yet importantly.

Canon S120: Easy-Grip Versatility

The Canon S120 measures 100x59x29mm and weighs a manageable 217g - light enough to slip into a coat pocket, but with a slightly chunky feel that lends confidence in hand. Canon opts for a rounded grip on the front, making it less slippery and more natural for clubs of thumbs to find purchase during extended shooting sessions. The rear sports a bright, 3-inch touchscreen LCD, a modern feature increasing ease of use despite no electronic viewfinder (EVF).

Notably, Canon’s fixed lens covers a versatile 24-120mm focal range (in 35mm terms) coupled with a respectable aperture range of f/1.8-5.7, giving you flexibility from wide-angle landscapes to short telephoto portraits.

Ricoh GR Digital III: Simplified, Street-Ready Precision

The Ricoh GR Digital III is slightly larger yet slimmer at 109x59x26mm and lighter at 208g. It’s built with a minimalist design ethos catered towards street photographers who demand discretion and rapid operation. It features a 28mm f/1.9 fixed prime lens - an iconic focal length praised for capturing intimate, lifelike scenes in a way zooms often can't match.

Its rear 3-inch display is not touchscreen - a quirk in today’s standards but less of a dealbreaker if you prefer tactile button controls and know your way around manual settings without fuss. It’s compactness combined with that fast prime lens offers a distinct advantage for candid shooting.

Overall, both offer great portability, but Canon slightly leads ergonomics for casual users, whereas Ricoh leans into specialist street and documentary photography needs.

Interface and Control Layout: Hands-On Usability

When testing cameras in the field, intuitive controls can make or break your user experience especially under fast-moving circumstances.

The Canon S120 features a thoroughly modern interface with a touchscreen TFT PureColor II G LCD - super bright and responsive, letting you adjust settings on the fly or frame shots easily in live view. Physical dials and buttons are well spaced, though not exactly chunky. If you prefer tactile dials for shutter speed or aperture control (the S120 supports shutter priority, aperture priority, and full manual), you might find this a bit fiddly compared to some DSLR-inspired designs, but acceptable for a compact.

In contrast, Ricoh’s GR Digital III sacrifices a touchscreen for a clear, button-driven interface with dedicated manual controls that feel like a tiny club of buttons assembled specifically for photographers who know their exposure triangle. The camera’s manual focus ring is standout - precise and smooth - an important trait for macro or deliberate street shots.

While Canon edges out with modern UI conveniences (like touch AF and rear screen navigation), Ricoh’s dial-based scheme rewards those ready to engage more deeply with camera controls - a real nod to enthusiasts.

Sensor and Image Quality: The Heart of the Matter

Let’s dive into what truly affects your photos: image quality from the sensors, coupled with lens characteristics and image processing.

Both cameras employ 1/1.7" sensors measuring 7.44x5.58mm with an active area of approx 41.52mm² - a relatively small sensor by today’s standards but still capable of producing excellent images when paired with quality optics and good processing engines.

Canon S120’s 12.1MP BSI-CMOS Sensor + DIGIC 6 Engine

Canon’s S120 steps ahead here with a 12-megapixel backside-illuminated CMOS sensor, combined with the DIGIC 6 processor. The BSI technology generally improves light-gathering efficiency, which translates to better low-light capability, cleaner high-ISO images, and improved dynamic range compared to older CCD tech or front-illuminated CMOS sensors.

On paper and in practice, the S120 produces images with good color depth (21.3 bits on DXOMark tests) and excellent dynamic range (11.9 EV), making it especially suited for landscape and outdoor photography demanding tonal gradation.

Ricoh GR Digital III’s 10MP CCD Sensor + GR Engine III

Ricoh’s GR Digital III was a throwback in sensor tech when launched, relying on a 10MP CCD sensor with the company’s GR Engine III processor. While CCD sensors are known for producing images with pleasing color rendition and less risk of digital artifacts, they tend to fall behind in noise performance and dynamic range compared to newer CMOS sensors.

DXOMark has not tested this sensor, but field evidence shows images have a distinct "film-like" character with excellent microcontrast but suffer more in low-light noise and highlight recovery.

Resolution & ISO Considerations

Canon’s 12MP sensor allows for higher resolution (max image size 4000x3000 px), whereas Ricoh maxes out at 3648x2736 px. Moreover, Canon supports native ISO 80-12800, while Ricoh has a narrower ISO spread (64-1600), limiting its utility in low-light conditions.

In landscape and travel, the Canon S120’s flexibility in ISO and dynamic range gives clearer, more versatile images, while Ricoh’s output shines best in well-lit, moderate contrast scenes.

Autofocus, Stabilization, and Burst Shooting: Performance When It Counts

Every photographer knows that a camera’s focusing system can be its Achilles heel or secret weapon.

Canon S120: Versatile AF and Optical Stabilization

Canon’s S120 offers nine contrast-detection AF points, face detection, touch AF, continuous AF, and AF tracking modes. Although not as fast as phase-detection systems in DSLRs or mirrorless cameras, in compact cameras, this is a solid package enabling decent subject tracking. The ability to select AF points on the touchscreen adds precision, especially for portraits or macro.

Equally important is the S120’s optical image stabilization system compensating for camera shake, allowing handheld shots down to shutter speeds normally challenging without a tripod - invaluable for night, macro, or telephoto shots.

Moreover, the 12 fps continuous shooting speed is impressive for the class, suiting sports and wildlife to an extent.

Ricoh GR Digital III: Point and Shoot Simplicity

Ricoh’s autofocus uses a contrast-detection system with multi-area AF but lacks continuous AF or subject tracking. Manual focus is excellent thanks to the smooth focus ring, but AF speed on moving subjects is middling - less ideal for dynamic sports or wildlife.

No image stabilization is a significant limitation, demanding either higher shutter speeds or tripods to prevent blur in low light or macro situations.

Continuous shooting modes are absent or very limited, limiting utility for action photography.

Displays, Viewfinders, and Interfaces: Seeing Your Shot

Viewing your subject correctly remains paramount in framing and exposure decisions.

The Canon S120’s 3-inch, 922k-dot touchscreen not only provides bright, clear framing but also supports touch focus and quick menu navigation. This can speed up workflow - particularly for content creators or beginners transitioning from smartphones to dedicated cameras.

The Ricoh GR Digital III’s 3-inch, 920k-dot fixed screen lacks touchscreen functionality but maintains excellent color accuracy and contrast in daylight. Ricoh offered an optional optical viewfinder (sold separately), which some photographers crave for more traditional composition - advantageous for street shooters wanting to keep the camera close to their eye.

If shooting in bright sunlight and preferring an EVF, you might find neither ideal since the S120 lacks viewfinder and Ricoh’s is optional and optical. However, the S120’s screen visibility is generally superior.

Lens and Macro Capabilities: Flexibility in Framing

Lens specs are often dealmakers in compact cameras. The Canon’s zoom range is wide and handy, with a 24-120mm equivalent focal length and fast f/1.8 aperture at the wide end. That lets you shoot wide vistas and portraits with attractive background blur (bokeh), especially at the wide aperture settings.

Ricoh offers only a 28mm equivalent 1.9 aperture prime lens - a field-of-view cherished by street and documentary photographers. It’s sharp, crisp, and has excellent corner-to-corner resolution, but no zoom. You commit to a single framing style.

When it comes to macro, the Canon S120 has a very impressive minimum focusing distance of 3cm with lens macro mode, combined with optical stabilization and touch AF that help nail focus on tiny subjects. The Ricoh brings the minimum focus down to an even sharper 1cm, rewarding detail lovers - though you’ll need to be careful about hand shake due to no stabilization.

Video and Connectivity Features: Ready for Hybrid Shooters?

For creators wanting stills plus video capability in one device, the Canon S120 holds a clear advantage.

It records full HD 1080p video at 60fps or 30fps using MPEG-4/H.264 codecs - suitable for smooth clips and online sharing. It also features a built-in stereo microphone (though no mic/phone ports), optical image stabilization aiding in handheld video, and Wi-Fi for easy wireless image transfer and remote control via smartphone apps.

In contrast, the Ricoh GR Digital III’s video is limited to VGA resolution (640x480), which feels archaic for today’s standards. No HDMI out, no Wi-Fi, no video audio input/output features make it strictly a still-image device.

If hybrid still/video creation matters, Canon S120 is the functional choice; the Ricoh is strictly for high-quality photography first.

Battery Life and Storage: Real-World Shooting Duration

For field reliability, battery endurance is a core concern.

Canon’s S120 uses the NB-6LH battery pack offering approximately 230 shots per charge per CIPA standards - not exceptional but decent considering the small body and bright screen. Carrying a spare battery is advisable for day-long shoots.

Ricoh’s GR Digital III battery life specs are not clearly indicated, but user reports and my experience suggest similar or slightly less endurance due to older battery technology and lack of power-saving features.

Both cameras use single SD card slots with standard SD/SDHC/SDXC compatibility - sufficient for casual and enthusiast photographers, though professionals typically want dual slots for redundancy.

Build, Weather Resistance, and Durability

Neither the Canon S120 nor the Ricoh GR Digital III offers significant weather-sealing or rugged construction. Both are designed for everyday shooting but require some care against dust and moisture. If you’re a travel or wildlife photographer often shooting in challenging environments, you’ll need to complement these cameras with protective cases.

Price-to-Performance: Which Packs More for Your Buck?

At their original launch prices - Canon around $449 and Ricoh about $399 - these cameras were neck and neck in affordability. Today, in the used market, the Ricoh often comes cheaper, but you sacrifice features like HD video, stabilization, and touchscreen.

The Canon S120 offers more versatility - zoom, video, wireless, optical stabilization - at the cost of slightly higher weight and complexity.

Ricoh GR Digital III is a more focused tool: prime lens with excellent optics for those specialized in street, travel, or documentary styles who don’t want or need zoom or video.
