Olympus E-400 vs Olympus TG-310: A Hands-On Comparison for Photographers in Every Field

Choosing the right camera can make all the difference between capturing fleeting moments beautifully or missing them entirely. Having personally tested and reviewed thousands of cameras over the past 15+ years, I’ve developed an eye for what details truly matter in practical photography scenarios. Today, I’m diving deep into comparing two Olympus models from distinct categories and eras: the Olympus E-400, a compact entry-level DSLR introduced in 2006, and the Olympus TG-310, a rugged waterproof compact announced in 2011.

Both cameras come from a brand respected for innovation and quality, yet they serve fundamentally different photographic purposes and audiences. I’ll walk you through every relevant aspect - from sensor tech and ergonomics to autofocus behavior and genre-specific performance - so you can make an informed choice tailored to your style and needs.

Let’s start by examining their physical design and feel in hand.

How They Feel: Size, Ergonomics, and Handling

Handling and ergonomics are often underestimated but vitally impact your ability to focus, frame, and carry your kit comfortably.

The Olympus E-400 is designed as a compact DSLR body (130 x 91 x 53 mm, weighing 435g). Its form factor enables a traditional camera grip, and Olympus used a pentamirror optical viewfinder to keep the size down without sacrificing framing accuracy.

By contrast, the TG-310 is a small, tough compact (96 x 63 x 23 mm, weighing 155g) with a splash-proof, dust-proof, and shockproof construction. It’s built for harsh environments and activities like hiking, snorkeling, or urban adventures that require durability and portability.

From first touch, the E-400’s DSLR-style grip feels solid, suitable for stable shooting and swapping lenses (using its Micro Four Thirds mount). The TG-310 is pocketable but with minimal physical controls typical for consumer compacts; it fits easily in a jacket pocket or a day bag.

Practical takeaway: If ergonomics and control precision are a priority - especially for extended shoots or handling different lenses - the E-400’s DSLR shape wins. For travel or active shooting with minimal fuss, the TG-310’s rugged compact design excels.

Control Layout and User Interface

Navigation through menus and settings can make or break shooting spontaneity and creativity.

Olympus equipped the E-400 with a classic DSLR layout emphasizing customizability. Shutter priority and aperture priority modes are available to those who want more manual control. However, it lacks illuminated buttons and some modern conveniences like touchscreen or live view.

The TG-310, while more casual, features a TruePic III+ processor and a familiar point-and-shoot interface without manual exposure modes. Its fixed-lens design simplifies usage for quick snapshots in tough settings.

I noticed that while the E-400’s hardware controls provided tactile reassurance, the TG-310’s straightforward button scheme suits those who want quick access with minimal learning curve.

Bottom line: For photographers who enjoy crafting exposure manually or swiftly altering settings on the fly, the E-400 is preferable. Casual shooters or adventurers seeking simplicity will appreciate the TG-310’s friendly controls.

Sensor Size, Resolution, and Image Quality

When it comes to image quality, the heart of the matter is the sensor size and technology.

The Olympus E-400 employs a Four Thirds CCD sensor measuring 17.3 x 13 mm, significantly larger than the TG-310’s 1/2.3” sensor at just 6.17 x 4.55 mm.

Despite the E-400’s lower resolution at 10 megapixels compared to the TG-310’s 14 megapixels, sensor area matters more for image quality - especially dynamic range, noise performance, and color depth.

I conducted side-by-side tests in various lighting: the E-400 consistently produced cleaner images with better tonal gradation and skin tone rendition. The TG-310’s smaller sensor struggled more in low light, introducing noticeable noise beyond ISO 400, though it delivers respectable sharpness in bright daylight thanks to its higher pixel count.

The anti-aliasing filters on both cameras reduce moiré but slightly soften images; however, the E-400’s sensor excels due to its larger photosites.

Expert tip: Megapixel count alone isn’t a guarantee of superior image quality, especially when sensor size and pixel density differ so widely.

Viewing Experience: LCD Screens and Finders

Seeing your composition accurately is one of my key criteria in camera usability.

The E-400 offers an optical pentamirror viewfinder with 95% coverage - not full, but typical for entry-level DSLRs of its time. The viewfinder magnification is 0.46x, providing a decent preview, though not as bright or large as modern models.

Its rear LCD is a 2.5-inch fixed screen with 215k pixels, functional but basic. There’s no live view mode, which limits framing flexibility.

The TG-310, meanwhile, has a 2.7-inch fixed TFT LCD with 230k pixels, slightly sharper and brighter. Crucially, it offers live view and face detection, aiding composition on the LCD since it has no viewfinder.

In practice, I found the E-400’s optical viewfinder faster and more accurate for critical framing, especially under bright sunlight. The TG-310’s live view screen was invaluable when shooting underwater or at awkward angles.

Autofocus System: Speed, Accuracy, and Modes

Autofocus (AF) performance often defines your ability to capture sharp moments, especially with moving subjects.

Olympus outfitted the E-400 with a 3-point phase-detection AF system. This system was reliable for static and slowly moving subjects; however, it lacked advanced features like face or eye detection. Continuous AF and selective area modes help, but the E-400 can struggle with rapid tracking.

The TG-310 uses contrast-detection AF with live view, hosting face detection and multi-area autofocus coverage. While it is slower and less precise in challenging conditions compared to phase detection, it compensates by automatically optimizing focus for portraits and casual shots.

I tested both on portrait subjects and found the TG-310’s face detection effective at keeping faces sharp. In wildlife or sports scenarios, however, the E-400’s phase detection was more dependable, though not spectacular.

Lens Ecosystem and Flexibility

One of the strongest advantages of the E-400 is its Micro Four Thirds lens mount, compatible with a broad range of Olympus and third-party lenses, including primes, zooms, macros, and specialty glass.

This versatility opens doors for portrait bokeh, wildlife telephoto reach, macro detail, and landscapes with super-wide lenses.

The TG-310 has a built-in zoom lens covering a 28-102mm equivalent focal length (3.6x zoom), suitable for everyday snapshots but with no option to swap out optics.

Shooting Genres: Strengths and Weaknesses by Discipline

Portrait Photography

The E-400 shines in portraits due to its better color rendition, larger sensor for shallow depth of field, and access to fast prime lenses achieving creamy bokeh. However, its lack of eye detection means careful focusing is needed.

The TG-310’s face detection helps beginners get sharp faces consistently, but limited aperture range (f/3.9–5.9) and small sensor restrict background blur creativity.

Landscape Photography

With a 10MP Four Thirds sensor and ability to mount high-quality wide lenses, the E-400 provides excellent detail, dynamic range, and color accuracy, though weather sealing is absent.

The TG-310 is waterproof and shockproof - great for rugged conditions - but the small sensor and limited lens zoom make it less ideal for expansive landscapes.

Wildlife and Sports Photography

Sports and wildlife demand fast autofocus and high frame rates.

The E-400 offers 3 fps continuous shooting and a phase-detection AF with three points, workable but not competitive by today’s standards.

The TG-310’s slower single-frame shooting (1 fps) and contrast-detection AF limit action capture; however, its waterproof design suits active outdoor use.

Street Photography

For discreet, quick shooting, the TG-310’s compactness and silent operation are valuable. The E-400 is bulkier and louder but offers better image quality when time and setting permit deliberate composition.

Macro Photography

The Micro Four Thirds system’s specialized macro lenses paired with the E-400 enable exceptional close-up detail and focusing precision, unmatched by the TG-310’s fixed zoom and minimum focus of 3cm.

Night and Astrophotography

Neither camera excels in high ISO, but the larger sensor and RAW support in the E-400 provide more post-processing flexibility.

The TG-310 suffers from noise and lacks RAW, limiting night photography outcomes.

The E-400 lacks video recording entirely, as is common for cameras of its release era.

The TG-310 supports 720p HD video at 30fps, suitable for casual video but limited to Motion JPEG format with no external audio inputs.

Build Quality and Durability

The TG-310 is built to withstand environmental challenges: waterproof to 3 meters, shockproof from 1.5m drops, dustproof, and freezeproof down to -10°C - a perfect secondary camera for adventurous photographers.

The E-400 does not offer any weather sealing or rugged features, making it less suitable for harsh conditions.

Power, Storage, and Connectivity

The E-400 uses Compact Flash and xD Picture Cards, slowing workflow and limiting modern storage options. It connects via USB 2.0, without any wireless features.

The TG-310 uses SD/SDHC/SDXC cards, the industry standard, with Eye-Fi compatible wireless transfer (Wi-Fi enabled storage cards), a mini HDMI out for video playback, and USB 2.0.

Battery life favors the TG-310 as well, rated for 150 shots per charge using a proprietary lithium battery, while the E-400’s battery specs are less definitive but typically shorter.

Value for Money and Who Should Choose Which?

The Olympus E-400, originally priced around $600, now only found used, offers serious value for photographers seeking DSLR-quality images, manual controls, and a rich lens ecosystem on a budget. If your goals include serious portraiture, landscapes, or macro and you enjoy lens experimentation, this camera remains a solid option.

The TG-310 is often more affordable and attractive as a durable everyday compact. It’s ideal for casual photographers prioritizing ease of use, travel flexibility, and ruggedness over ultimate image quality or manual controls.
