Having extensively tested thousands of cameras personally, I will unpack their detailed specifications, hands-on performance characteristics, and practical value across various photography disciplines. Whether you’re a portrait artist, wildlife enthusiast, street photographer, or travel documentarian, this comparison will help clarify which Olympus model better suits your shooting demands, budget, and long-term needs.

First Impressions: Size, Ergonomics, and Handling

Physical usability is foundational to any camera experience. The Olympus E-300 features a mid-sized DSLR body with well-marked controls and a traditional SLR form factor. In contrast, the Olympus TG-320 is a small, compact waterproof camera designed for ease of use in rough environments where bulkier gear is a liability.

At 147x85x64 mm and 624 grams, the E-300 is considerably larger and heavier than the TG-320, which measures just 96x63x23 mm and tips the scales at a featherweight 155 grams. The E-300's bulkier body offers a more substantial grip suited for prolonged handheld shooting with interchangeable lenses, while the TG-320’s slim frame fits comfortably in a pocket or backpack without compromising portability - a critical factor for travel photographers or outdoor sports shooters.

Ergonomically, the E-300 provides dedicated buttons and dials typical of DSLRs, facilitating quick adjustment of shutter speed, aperture, and exposure compensation. The TG-320, prioritizing simplicity, lacks manual exposure modes and relies heavily on automatic scene adaptations. Consequently, the E-300 accommodates more detailed control for enthusiasts and professionals, while the TG-320 aims for straightforward point-and-shoot ease.

Sensor Technology and Image Quality: From Four Thirds to 1/2.3" Compact

Image fidelity fundamentally depends on sensor size and technology, often the deciding factor for image quality in varying lighting conditions.

The E-300 is equipped with an 8-megapixel Four Thirds CCD sensor measuring 17.3 x 13 mm (approximately 225 mm² sensor area), significantly larger than the TG-320’s 14-megapixel CCD sensor sized at 6.17 x 4.55 mm (approximately 28 mm²). Larger sensors generally collect more light and achieve better dynamic range, color depth, and low-light sensitivity - a clear edge for the E-300. However, note that the E-300’s modest 8MP native resolution reflects the technology available during its 2005 launch.

On the other hand, the TG-320’s sensor, though smaller, offers a higher 14MP resolution, which can yield crisper images with more detail under optimal lighting but tends to struggle in shadows and high ISO scenarios due to smaller photosites and increased noise.

The E-300 supports RAW shooting - a crucial feature for post-processing flexibility - whereas the TG-320 does not, limiting users to JPEG workflows.

In practical tests, the E-300’s larger sensor and Four Thirds lens system produced noticeably better tonal gradation, color accuracy, and controlled noise at ISO 100-400. Meanwhile, the TG-320 excelled in daylight scenarios, swiftly delivering usable images suitable for social sharing, but quickly showed weaknesses as lighting dimmed or dynamic range demands increased.

Autofocus: Precision vs. Practicality

The autofocus system is a pivotal usability factor, especially across dynamic shooting scenarios.

The E-300 employs a phase detection autofocus system with three focus points and offers continuous AF in burst shooting (3 fps). While the limited number of AF points may feel modest by today’s standards, for its time it provided reliable and fast focusing suited to deliberate shooting - portraiture, landscapes, and staged compositions.

Conversely, the TG-320 uses contrast-detection autofocus with face detection capabilities, emphasizing user-friendly autofocus in a compact camera. Its AF is optimized for still subjects in casual photography rather than aggressive tracking. With a single FPS continuous shooting rate, burst capturing is not the TG-320’s strength.

For wildlife or sports, where fast and precise AF tracking is paramount, the E-300, despite its age, offers moderately better control, especially paired with Olympus' extensive lens lineup.

Build Quality and Environmental Durability

Olympus targeted two very different shooting environments with these cameras.

The E-300's chassis is a mid-sized plastic DSLR body without weather sealing or rugged features; it excels indoors and in controlled environments but demands care in harsh weather.

The TG-320, by contrast, features robust waterproof (up to 3 meters), dustproof, shockproof, and freezeproof construction, designed expressly for adventurous use - hiking, snorkeling, beach outings, and extreme weather conditions. This ruggedness is unmatched by the E-300, making the TG-320 excellent for photographers who prioritize durability and portability over manual control and sensor size.

LCD Screens and User Interface

User interface dictates how easily photographers can frame and review their shots.

The E-300 sports a small 1.8-inch fixed LCD with a modest 134k-dot resolution, reflecting early DSLR technology. Its optical pentamirror viewfinder allows precise framing and exposure judgment in bright conditions but lacks electronic overlays or coverage specs. Interface resembles traditional DSLR layouts with physical buttons but lacks illuminated controls.

The TG-320 features a larger, sharper 2.7-inch TFT color LCD at 230k dots, offering live view and menu navigation that is more accessible for beginners and casual users.

While the E-300 demands some learning curve, the TG-320 emphasizes intuitive interaction - useful for spontaneous shooting in the field.

Lens Systems and Compatibility

The lens ecosystem arguably defines a camera's versatility over time.

The E-300 uses the Four Thirds mount and benefits from Olympus's rich lineup of 45 native lenses (manual, autofocus, primes, zooms, macro, telephoto), enabling photographers to customize optics for various genres - portraits, macro, wildlife, landscape, and sports.

This flexibility offers great creative freedom. Its 2.1x crop factor means telephoto reach is doubled relative to full frame, advantageous for wildlife and sports, albeit at the cost of wide-angle breadth.

The TG-320's fixed lens covers 28-102 mm equivalent focal range (3.6x zoom) with an aperture spanning f/3.5–5.1. It includes a macro focus as close as 3 cm for close-ups but is limited by the built-in optics. Its lens system is inherently more limited and not upgradable, reflecting its design as an all-in-one system for hassle-free shooting.

Shooting Performance: Shutter, Burst Rate, and Stabilization

The E-300's shutter mechanism ranges from 60 seconds to 1/4000 second, appropriate for manual exposure workflows and long-exposure options but without electronic shutter modes. The 3 fps burst rate supports sports and action photography at beginner levels.

The TG-320 has a shutter range from 4 to 1/2000 seconds, lacking manual exposure modes or priority settings, pushing users toward full auto or limited program modes. Continuous shooting is limited to 1 fps, making it suboptimal for fast action.

Notably, the TG-320 incorporates sensor-shift image stabilization, a boon for handheld shooting, especially in low light or at telephoto zoom lengths. The E-300, lacking in-body stabilization, relies on stabilized lenses (which were less standard at the time), reducing handheld flexibility.

Battery Life and Storage

Battery considerations impact workflow and portability.

The TG-320 uses the rechargeable Li-42B battery promising approximately 150 shots per charge, considered modest but typical for compacts of its generation.

The E-300 lacks officially published battery life figures but uses proprietary rechargeable batteries with the option for external battery grips. DSLR power consumption and image processing are higher, so endurance depends on battery capacity and usage.

Both cameras utilize a single storage slot: Compact Flash for the E-300 and the more modern SD/SDHC/SDXC cards for the TG-320, with the SD format offering higher convenience due to market ubiquity.

Video Capabilities

Video is a critical consideration for hybrid shooters.

The E-300 does not offer video recording functionality.

The TG-320 supports HD video capture at 1280x720 pixels at 30 fps using MPEG-4/H.264 codecs, adequate for casual video recording but without advanced options like manual exposure control or external audio inputs.
