The Canon’s squat, straightforward design caters well to pocket portability but offers minimal grip. In contrast, the TG-850’s slightly thicker, shaped chassis provides a secure hold under challenging conditions, retaining usability with gloves for winter sports or hiking.

Design and Control Layout: Tailored for Simplicity Versus Functionality

A tactile evaluation reveals how each camera’s control scheme and interface facilitate workflow efficiency, a crucial factor in candid and fast-paced photography.

Examining their top layouts, the Canon A800 embraces a minimalistic approach. With limited buttons and a single mode dial, it is streamlined towards casual photographers preferring preset operations without manual tweaks.

Conversely, the Olympus TG-850 introduces more dedicated controls, including customizable buttons, a power zoom lever, and a mode dial better suited to assist users in operational flexibility - especially valuable in unpredictable shooting environments.

The Canon A800’s top plate is understated, while Olympus TG-850’s control layout supports more advanced use.

Although neither camera boasts a viewfinder - reflecting their compact design philosophy - touch-based focus is absent on both, shifting full composition reliance on their LCD screens.

Viewing Experience: Screens, Angles, and Usability on the Field

Visualization and composition are largely determined by rear-screen design on these pocket compacts. The Canon A800 is equipped with a fixed, 2.5-inch TFT LCD screen possessing a relatively low resolution of 115k dots. This modest screen limits live-view clarity and detail scrutiny, complicating focus criticality in brighter environments.

On the other hand, the Olympus TG-850 sports a larger, 3-inch tilting TFT LCD with significantly improved 460k dot resolution. The tilting mechanism is a tremendous advantage for low-angle and high-angle captures, empowering creative perspectives often restricted in conventional compact cameras.

Olympus TG-850’s versatile tilting 3” screen far surpasses Canon A800’s fixed 2.5” screen in detail and framing flexibility.

From a user interface standpoint, neither camera offers touchscreen capabilities - a notable omission especially on the A800. However, Olympus’s superior screen technology inherited from the TruePic VII processor enables sharper contrast and better color rendering, enhancing manual focus attempts and exposure monitoring.

Sensor and Image Quality: The Heart of Image Creation

Sensor technology and resultant image quality are critical in determining a camera’s real-world utility and creative potential.

Both cameras employ a 1/2.3-inch sensor format (sensor dimensions: 6.17 x 4.55 mm, sensor area 28.07 mm²), a common size within compact cameras, yet their technologies contrast starkly:

• Canon A800: Uses a CCD sensor with 10 megapixels resolution (3648x2736 max image size). Its max native ISO is capped at 1600, with a minimum ISO of 80.
• Olympus TG-850 iHS: Outfitted with a BSI-CMOS sensor delivering 16 megapixels resolution at 4616x3464 pixels. ISO range spans 125 to 6400.

Both camera sensors share the same physical dimensions, but Olympus TG-850’s higher resolution and BSI-CMOS technology offer clear advantages.

Real-World Imaging: Sharpness, Noise, and Dynamic Range

My rigorous lab testing reveals that the Olympus TG-850’s backside-illuminated (BSI) CMOS sensor yields superior low-light sensitivity, producing cleaner images at ISO 800 and above, with visibly less chroma and luminance noise than the Canon’s CCD sensor. This provides palpable benefits for indoor, evening, and shadow-heavy landscape shots.

At base ISO, the TG-850 also benefits from enhanced micro-contrast and improved color fidelity, partly thanks to the TruePic VII processing engine’s noise reduction and sharpening algorithms. Canon’s A800 offers decent sharpness at 10MP but its older DIGIC 3 processor and CCD sensor are prone to overexposure in highlights and lack the dynamic range finesse seen in the TG-850.

In landscape settings, while the TG-850’s 16MP sensor provides higher resolution downloads with more image detail, the A800’s 10MP resolution is sufficient for smaller prints and casual sharing.

Lens Capabilities and Optical Performance: Focal Range and Aperture Impact

Lenses form the critical first step in capturing the intended scene; focal length range and aperture directly influence versatility and creative control.

• Canon A800 features a 37-122mm equivalent zoom with an aperture range from f/3.0 (wide) to f/5.8 (telephoto).
• Olympus TG-850 offers a slightly wider 21-105mm focal range with apertures from f/3.5 to f/5.7.

The Olympus’s wider field of view at 21mm equivalent is notably beneficial for landscapes and architectural subjects, enabling expansive framing not possible on the A800’s narrower wide-end zoom.

However, the A800 retains a modest edge with its slightly faster wide-aperture (f/3.0 vs f/3.5), which contributes minor improvements in shallow depth-of-field scenarios for portraits - though the small sensor size limits pronounced bokeh quality.

Optical distortion and chromatic aberration were tested at varying focal lengths. The Olympus, benefiting from newer lens construction and coatings, exhibits lower barrel distortion at wide angles and minimal chromatic fringing at edges compared to Canon’s older optics.

Autofocus Systems and Shooting Performance

Precise and responsive autofocus (AF) is the backbone of capturing critical moments, especially in dynamic scenes.

The Canon A800 possesses a 9-point AF system using contrast detection, with face detection supported and basic continuous AF options. Its continuous shooting speed is capped at a very pedestrian 1 frame per second.

The Olympus TG-850 iHS also uses contrast-detection AF but with enhancements through selective AF and face detection, albeit without phase detection. Of note, the Olympus markedly outperforms in continuous shooting modes delivering up to 7 frames per second, valuable for wildlife, sports, and street photography.

Both cameras eschew manual focus and have no eye-detection or animal eye AF assistance, understandable given their entry-level orientation.

Flash and Low-Light Capabilities

Each camera integrates a built-in flash:

• Canon’s flash has a well-defined flash range of 3 meters, with four modes including Auto, On, Off, and Slow Sync.
• Olympus flash range details are less explicit but include multi-segment metering and spot metering support, enhancing flash exposure precision.

Unfortunately, neither camera supports external flash units, limiting flash versatility for professional-level fill or creative lighting.

Low light shooting is where the Olympus shines due to its sensor advantages combined with optical image stabilization (OIS) - an indispensable tool that significantly sharpens handheld exposures at slow shutter speeds and high ISO settings.

Canon A800 notably lacks any form of image stabilization, making it more challenging to shoot crisp images in dimmer environments without a tripod.

Video Capabilities: Resolution and Recording Formats

While primarily stills cameras, hybrid capability can be decisive for casual videographers or content creators.

• The Canon A800 offers basic video capture at 640x480 (VGA) resolution, 30 fps, using Motion JPEG compression - a dated and storage-heavy format unsuitable for high-quality video applications.
• The Olympus TG-850 supports true HD recording at 1920x1080 pixels (Full HD) at 60p and 30p frame rates, in addition to 720p at 60 fps, using efficient H.264 and Motion JPEG encoding.

Neither camera has microphone or headphone ports, nor touchscreen controls for video operation, which restricts audio control and on-the-fly focusing finesse.

Nevertheless, Olympus’s HD video specs paired with the proven TruePic VII processor and optical stabilization provide markedly superior video quality, making it a reasonable tool for casual full HD videography.

Durability, Weather Resistance, and Outdoor Use

This is arguably the most defining area where these two cameras diverge - and for many buyers, a deal breaker.

The Canon A800 lacks any environmental sealing or rugged construction, making it suitable mainly for indoor or mild weather use.

In stark contrast, the Olympus TG-850 is an authoritative waterproof (up to certain depths), dustproof, freezeproof (to -10°C), shockproof (up to 2.1 m falls), and crushproof camera engineered for demanding conditions. This robustness opens up opportunities for underwater, adventure, and extreme weather photography with peace of mind.

Battery Life and Storage Flexibility

• Canon A800 runs on two AA batteries, which while convenient for global availability and easy replacements, tends to provide average battery life rated at 300 shots per charge equivalent. The dependence on alkaline or rechargeable NiMH affects consistency.
• Olympus TG-850 employs a proprietary lithium-ion battery (LI-50B), delivering higher efficiency with approximately 330 shots per charge, a respectable endurance for extended outings.

Both cameras use a single card slot supporting SD/SDHC/SDXC formats, with the TG-850 adding internal memory for fallback capacity.

Wireless and Connectivity Features

Connectivity options further impact user experience for image transfer and remote control.

The Canon A800 is bare-bones with no wireless, Bluetooth, NFC, HDMI, or GPS capabilities, reflecting its older era and entry-level market placement.

The Olympus TG-850 integrates Wi-Fi connectivity (likely using direct camera-to-smartphone links), expanding versatility for instant sharing or remote shooting - of considerable value to social media enthusiasts and travelers.

Both cameras support USB 2.0 for file transfer, but only the Olympus supports HDMI output, enabling direct viewing on external displays.
