Choosing the right compact camera often requires balancing ruggedness, image quality, manual control, and versatility. The Canon PowerShot G12, introduced in early 2011, marks a peak in Canon’s small-sensor enthusiast compacts emphasizing manual control and image fidelity, while the Olympus Tough TG-5, released in 2017, targets the adventurous photographer needing a dependable, splashproof, shockproof camera without sacrificing modern imaging features.

With over 15 years of professional experience evaluating cameras across genres and environments, I dissect these two popular compacts along every essential axis. This comprehensive comparative review will illuminate each model’s strengths, limitations, and ideal use cases, helping you make a fully informed acquisition decision.

A Tale of Two Compacts: Form Factor and Ergonomics

While both cameras are compact fixed-lens models, the design philosophies diverge markedly. The Canon G12’s classic, boxy shape favors tactile manual controls for photographers who like to manipulate settings directly, whereas the Olympus TG-5 prioritizes ruggedness and portability with a more modest ergonomic footprint optimized for outdoor use.

Physical Size and Handling

The G12’s dimensions (112x76x48mm) clearly outline a more substantial grip and heft (401g), benefiting stability during handheld shooting and offering a comfortable handhold comparable to entry-level DSLRs. In contrast, the TG-5’s smaller, slimmer profile (113x66x32mm) and lighter weight (250g) make it unobtrusive for travel, hiking, and underwater use.

From years of hands-on testing, the G12’s pronounced dials and buttons always provide quicker, more confident access to aperture, shutter speed, ISO, and exposure compensation controls, which is a major advantage in dynamic shooting conditions. Meanwhile, the TG-5 employs tactile but smaller buttons and mode dials geared towards intuitive outdoor operation - even with gloves on. However, this comes at the cost of fewer dedicated physical controls.

Control Layout and Top Panel Interface

The Canon G12’s top view reveals its manual control pedigree: dedicated mode dial, exposure compensation dial, shutter button with integrated zoom lever, and a clever exposure ring around the lens for aperture adjustment. This setup caters well to users accustomed to DSLR-like immediacy. The inclusion of an optical tunnel viewfinder, while dated, offers framing assistance under bright conditions.

Contrastingly, the TG-5’s more minimalistic approach excludes a viewfinder and replaces manual shutter control with aperture priority mode predominantly. Its mode dial integrates specialized functionality such as underwater modes and high-speed burst settings unique to Olympus’ Tough lineup. The absence of manual shutter priority or full manual modes reflects a deliberate emphasis on simplified usability for adventurous users prioritizing robustness over granular control.

Sensor, Image Quality, and Processing Capabilities

At the heart of any camera’s image quality is its sensor and processor. Understanding these technical foundations is vital to appreciating the real-world differences, especially in compact cameras with small sensors.

Sensor Specifications and Image Quality Metrics

The Canon G12 employs a 1/1.7" CCD sensor measuring 7.44x5.58mm (41.52 mm²) with a resolution of 10 megapixels (3648x2736), aligned with Canon’s Digic 4 image processor. CCD sensors traditionally deliver excellent color depth and dynamic range in daylight but tend to struggle in low light due to increased noise and readout lag. The DxOMark scoring confirms this: 20.4 bits of color depth, a dynamic range of 11.2 EV - which is respectable for its time - and relatively weak low-light ISO performance (ISO 161 equivalent).

The Olympus TG-5 houses a more modern 1/2.3" back-illuminated CMOS sensor (6.17x4.55mm, 28.07 mm²), capturing 12 megapixels (4000x3000) processed by Olympus’ TruePic VIII chip. Backside illumination boosts light-gathering efficiency, which along with newer sensor architecture, dramatically improves noise control and dynamic range, especially at high ISO levels - the TG-5 supports ISO up to 12,800.

In practical terms, the G12 excels in daylight and controlled lighting, yielding pleasing color fidelity and gradation that CCD sensors are known for. However, in dim or challenging lighting, the TG-5’s CMOS sensor outperforms, providing cleaner images and usable shutter speeds without excessive noise. Its high native ISO and stabilization also aid shooters capturing fast action or handheld landscapes at dusk or indoors.

Display, Viewfinder, and User Interface

Viewing and composing images efficiently is critical for fast-paced shooting and evaluating results on the fly.

Rear Screen and Interface Experience

The Canon G12 offers a 2.8-inch fully articulated LCD with 461k-dot resolution, affording flexible angles for shooting at high, low, or awkward angles. Articulated screens are a godsend for macro photographers and creative compositions requiring perspective variance. The screen's size and resolution remain decent, though by today’s standards it is dimmer and less sharp.

In contrast, the TG-5 features a 3.0-inch fixed LCD screen, also 460k dots, which is slightly larger but non-articulating. The screen is ruggedized for outdoor durability but lacks touch capability, limiting quick menu navigation. From my extensive testing, the lack of articulation on the TG-5 impedes creative framing options but benefits from an oleophobic coating for underwater clarity.

Viewfinder Considerations

The G12’s optical tunnel viewfinder, while helpful outdoors to steady composition, lacks overlay information and eye-level focus precision compared to modern electronic viewfinders (EVFs). The TG-5 excludes any viewfinder entirely, relying fully on the rear LCD - a compromise that may deter photographers used to eye-level composing but makes for a slim profile.

Autofocus Systems and Shooting Performance

Fast and accurate focusing is paramount, particularly for wildlife, sports, and street photographers who cannot wait to confirm focus.

Autofocus Architecture

The Canon G12 uses contrast-detection AF with 9 AF points and offers face detection but lacks advanced tracking or continuous autofocus modes; continuous AF is absent, capping continuous shooting at 1 frame per second (fps). This setup makes the G12 more suitable for deliberate, static compositions instead of fast action scenes.

On the other hand, the Olympus TG-5 employs a 25-point contrast-detect AF system with face detection and continuous AF tracking, which supports burst shooting up to 20fps - a substantial improvement for capturing rapid events or wildlife sequences. User-oriented features such as selectable autofocus areas and focus bracketing/stacking further enhance its creative utility.

Burst and Shutter Speed Ranges

The G12 sports a shutter speed range from 15 seconds to 1/4000 second, excellent for long exposures and daylight shooting, but its low continuous shooting speed (1 fps) and absence of silent or electronic shutter limit its sports and wildlife viability.

The TG-5 offers shutter speeds between 4 and 1/2000 seconds - not quite as broad - but compensates with high-speed continuous shooting and an advanced electronic shutter in some modes (though limited), ideal for action bursts and minimizing shutter noise underwater or in quiet settings.

Lens Characteristics and Macro Capabilities

Lens performance influences image sharpness, distortion, and creative expression.

Focal Length and Aperture Range

Both cameras have fixed zoom lenses but differ in ranges and maximum aperture:

• Canon G12: 28-140mm equivalent with a fast constant starting aperture of f/2.8 tapering to f/4.5 at telephoto. This wide-to-short-telephoto range supports versatile shooting from landscapes to portraits, with a bright lens aiding low-light and shallow depth-of-field effects.

• Olympus TG-5: 25-100mm equivalent lens starting wider at f/2.0 but closing to f/4.9. Olympus prioritizes a bright wide-angle for landscapes and close-ups, tailored to underwater and travel uses, though a shorter telephoto reach may limit distant subject framing.

Macro and Close Focusing

Both cameras excel at macro with a minimum focusing distance of 1cm. Olympus adds dedicated high-magnification modes and focus stacking features, enabling unprecedented close-up sharpness and depth-of-field extension in a rugged package. The Canon’s articulated screen complements macro framing but lacks stacking options.

Video Capabilities: Resolution and Image Stabilization

Videographers increasingly demand hybrid-capable cameras that deliver quality footage alongside stills.

The Canon G12 records HD video up to 720p at 24 fps with H.264 compression. Though serviceable for casual use, it lags behind modern standards, lacking Full HD (1080p) or 4K support, plus no in-body stabilization specific to video (only optical stabilization for stills).

The Olympus TG-5 leaps ahead with UHD 4K video at 30p and Full HD 1080p at 60p, encoded in MPEG-4 H.264, offering significantly sharper motion capture suited for social media and casual filmmaking. Its sensor-shift image stabilization effectively reduces camera shake in video, a big winner for handheld or action footage.

Neither camera supports external microphones or headphone monitoring, limiting pro-level audio control. Still, the TG-5’s video versatility makes it the preferable choice for vloggers and active shooters prioritizing video alongside photos.

Durability, Weather Sealing, and Travel Considerations
