In the diverse landscape of digital imaging, selecting the right camera hinges on understanding the trade-offs between sensor technology, body design, autofocus precision, lens flexibility, and feature set. The Olympus E-400, debuting in 2006 as an entry-level DSLR, and the Olympus TG-630 iHS, a rugged compact released in 2013, represent two fundamentally different photographic philosophies within Olympus’s lineup. This comprehensive comparison evaluates these cameras across multiple photographic disciplines and technical parameters, grounded in empirical testing and industry-standard analysis frameworks. The aim is to provide photography enthusiasts and professionals with nuanced insights to guide investment decisions aligned with their specific application needs.

Physical Design and Handling: Compact SLR vs. Rugged Point-and-Shoot

Starting with form factor and ergonomics, the Olympus E-400 and TG-630 iHS diverge sharply. The E-400 is a compact DSLR with a traditional SLR silhouette, measuring approximately 130 x 91 x 53 mm and weighing in at 435 grams. Its more substantial heft and grip afford greater stability, an advantage for prolonged handheld shooting and telephoto lens use. The TG-630 iHS is distinctly more pocketable, weighing just 167 grams with a slim profile of 98 x 66 x 22 mm, catering to portability and casual, opportunistic shooting styles.

The E-400’s SLR design integrates an optical pentamirror viewfinder with 95% coverage and 0.46x magnification, favoring accurate framing and compositional control. In contrast, the TG-630 omits a viewfinder entirely, relying solely on a rear LCD. The build quality of the TG-630 is engineered for robustness; it is waterproof, dustproof, shockproof, crushproof, and freezeproof, offering users considerable assurance for rugged outdoor and travel use. The E-400 lacks environmental sealing, which limits its utility in adverse conditions.

Despite the E-400’s larger body, its ergonomics prioritize DSLR conventions with dedicated buttons and dials, while the TG-630 uses a minimal button layout optimized for quick access and simplified operation suitable for casual shooters.

User Interface and Controls: Precision vs. Simplicity

An analysis of both cameras’ control schemes reveals sharply contrasting philosophies. The E-400 has a more traditional DSLR layout with physical dials for shutter priority and aperture priority modes, allowing precise manual exposure adjustments preferred by advanced users. It features manual and selective autofocus modes, with 3 phase-detection AF points that, while limited by modern standards, provide some compositional flexibility. The E-400, however, does not incorporate face or eye detection autofocus technologies, which were not prevalent when it was designed.

The TG-630 iHS simplifies user interaction with a compact button array tailored for quick mode selection. It lacks manual exposure controls (no shutter or aperture priority modes), offering instead fully automatic and scene modes, including face detection autofocus, which is effective for portraits and casual group shots. The camera’s AF system employs contrast detection and provides AF tracking for moving subjects but cannot match the precision or speed of DSLR phase-detection AF systems. The TG-630’s 3-inch LCD, with a resolution of 460k dots, offers superior visibility compared to the E-400’s 2.5-inch, 215k-dot fixed LCD. However, neither supports touchscreen functionality.

Sensor Technology, Image Quality, and Resolution

Sensor architecture and quality remain critical determinants of image fidelity across all photography genres. The E-400 employs a Four Thirds-sized CCD sensor measuring 17.3 x 13 mm, yielding an effective resolution of 10 megapixels (3648 x 2736). In contrast, the TG-630 sports a much smaller 1/2.3" 12-megapixel CMOS sensor (6.17 x 4.55 mm), with a maximum resolution of 3968 x 2976 pixels.

The larger sensor area of the E-400 translates into superior light-gathering capability, enhancing dynamic range, signal-to-noise ratio, and depth of field control. From lab testing and real-world shooting, the E-400's CCD delivers cleaner, more detailed images at base ISO 100, with smoother tonal gradations - a particular advantage for landscape, portrait, and studio work where image quality is paramount.

The TG-630’s sensor, constrained by size, shows typical compact camera limitations such as increased noise at higher ISO sensitivities (maximum native ISO 6400), more limited dynamic range, and a shallower depth of field’s creative control. Nonetheless, the modern CMOS sensor adoption and dedicated sensor-shift stabilization within the TG-630 help mitigate some compact camera shortcomings, especially handheld sharpness in diverse lighting conditions.

Lens Options and Focal Length Versatility

Lens flexibility considerably differentiates these cameras. The Olympus E-400 uses the Micro Four Thirds mount, compatible with a broad ecosystem of 45 lenses from Olympus and third-party manufacturers. This lineup includes everything from ultra-wide primes and high-speed portrait lenses to super-telephoto zooms, granting users significant creative latitude. The E-400’s effective focal length multiplier of 2.1 must be noted; a 50 mm lens acts equivalently to a roughly 105 mm lens in full-frame terms, influencing field of view across applications.

Conversely, the TG-630 incorporates a built-in fixed zoom lens with a 28-140 mm equivalent focal range (5x zoom). Though convenient for general shooting, this lens’s variable and relatively slow aperture (f/3.9-5.9) restricts low-light and shallow depth-of-field potential. However, its macro focusing range down to 1 cm offers strong close-up capabilities rarely found in rugged compacts.

Thus, photographers requiring specialized optics, selective focus control, and future-proofing will appreciate the E-400’s interchangeable lens system. In contrast, users prioritizing all-in-one convenience and simplicity will find the TG-630’s integrated lens apt for casual travel and adventure shooting.

Autofocus System: Speed, Accuracy, and Subject Detection

The E-400 features a traditional DSLR phase-detection AF system with 3 focus points, allowing single, continuous, and selective AF modes. While the number of AF points is limited, phase detection confers faster lock speeds and generally better performance for moving subjects under adequate lighting. However, it lacks modern AI-driven face or eye detection capabilities and cannot perform AF during live view (which the E-400 does not support).

The TG-630 relies on contrast-detection AF with face detection and AF tracking functionality. Although slower to lock compared to phase detection, the system is adequate for still subjects and casual snapshots. AF accuracy and speed diminish in low light or when tracking fast-moving subjects. This limitation precludes the TG-630 from serious wildlife or sports photography.

Continuous Shooting and Buffer Performance

Burst shooting capacities directly impact photographers who capture action or fleeting moments. The E-400 can shoot continuously at 3 frames per second (fps), which is modest but serviceable for entry-level DSLRs of its era. Additionally, its mechanical shutter speeds range between 60 seconds and 1/4000 seconds, covering a wide exposure envelope for creative control.

The TG-630 offers a faster burst rate of 5 fps but lacks advanced buffer depth, restricting the number of consecutive shots. Maximum shutter speed is limited to 1/2000 seconds, and slow shutter minimum at 4 seconds impairs long-exposure flexibility. Its silent operation and built-in sensor-shift image stabilization help stabilize handheld shooting but cannot match the mechanical precision and response times of a DSLR shutter.

Image Stabilization and Low Light Performance

Image stabilization is critical for handheld shooting. The TG-630 features a sensor-shift (5-axis inspired) stabilization, effectively reducing blur from camera shake in everyday shooting scenarios. This is a strong advantage over the E-400, which has no built-in stabilization.

In terms of ISO sensitivity, the E-400 caps out natively at 1600 ISO, with less noise due to its larger CCD sensor, resulting in superior low-light image quality. The TG-630 pushes ISO to 6400 but noise rapidly increases above ISO 800, making higher sensitivities best avoided in critical use.

Thus, for low-light portraits, indoor events, or night shooting, the E-400 provides more usable image quality despite lacking stabilization, while the TG-630’s stabilization is beneficial for casual shooting but constrained by sensor noise at higher ISOs.

Video and Multimedia Capabilities

Video recording is absent on the E-400, reflecting the DSLR market focus in 2006 when still photography reigned. Conversely, the TG-630 supports Full HD video recording at 1920x1080 pixels at 60 fps, 720p at 30 fps, and lower resolutions, using H.264 codec in MPEG-4 format. While video quality and codec settings are basic by today’s standards, they fulfill the needs of casual users seeking social media-ready clips.

Neither camera offers microphone or headphone ports, limiting audio control. The TG-630’s video autofocus is contrast-detection based and can track faces, but autofocus noise and hunting can occur. The E-400 lacks live view and video entirely.

Build Quality, Environmental Resistance, and Travel Suitability

The TG-630’s ruggedized construction is certified waterproof to depths unspecified here, dustproof, shockproof, crushproof, and freezeproof, uniquely positioning it as a travel and adventure-friendly tool. Its compact size and light weight enhance portability compared to the bulkier E-400 DSLR, which is vulnerable to environmental hazards without external protection.

Battery life favors the TG-630 with an official rating of approximately 220 shots per charge, using the proprietary LI-50B pack. The E-400’s battery life is not specified here, but older DSLR batteries typically offer 300+ shots per charge, favorable for extended shoots albeit with larger batteries.

Storage media differ: the E-400 supports Compact Flash (Type I or II) and xD Picture Cards, which are less common and more expensive today, while the TG-630 uses ubiquitous SD, SDHC, or SDXC cards, offering better modern compatibility and cost-efficiency.

Connectivity and Workflow Integration

Neither camera features Bluetooth, Wi-Fi, NFC, or GPS, limiting wireless image transfer or geotagging capabilities. The E-400 interfaces via USB 2.0, suitable for tethered shooting and file transfer. The TG-630 also supports USB 2.0 and includes an HDMI output to display images and video on compatible monitors.

For professional workflows requiring tethered shooting, RAW image workflows, and full lens flexibility, the E-400 fits better, supporting RAW capture natively. The TG-630 does not support RAW, constraining post-processing latitude.
