Olympus E-400 vs Olympus Stylus 9000: An Expert Hands-On Comparison for Photography Enthusiasts

Selecting the right camera can be a nuanced decision, particularly when comparing two models from the same manufacturer yet aimed at vastly different user experiences and photographic needs. Today, I’m sharing insights from my extensive hands-on testing of two Olympus models: the Olympus E-400, an entry-level DSLR released in 2006, and the Olympus Stylus 9000, a small sensor compact camera launched in 2009. These cameras highlight contrasting philosophies: the E-400 embodies DSLR craftsmanship geared toward beginners wanting to grow into system photography, while the Stylus 9000 (also known as the mju 9000) appeals with versatile zoom in a pocketable design.

Over the course of testing hundreds of cameras over 15 years, I bring first-hand technical insights and real-world performance analysis to this head-to-head. Let’s dive deep into their core strengths and weaknesses across key photography disciplines, complemented by detailed technical breakdowns - so you can discover which Olympus camera best fits your creative goals and budget.

Size, Ergonomics, and Handling: Ready for the Shoot?

Understanding a camera’s physical presence affects your shooting experience profoundly, especially across genres like street, travel, and macro photography.

Olympus E-400
At 130x91x53mm and 435g, the E-400 is compact by DSLR standards but considerably larger and heavier than most compacts. Its traditional DSLR body offers a substantial grip, making it well suited for longer shooting sessions. The mirror box and pentamirror viewfinder design add bulk but also provide an optical viewfinder - valuable for frantic moments needing precise composition.

Olympus Stylus 9000
The Stylus 9000 is tiny - 96x60x31mm and just 225g. It slips inside a jacket or purse effortlessly, perfect for street photography and travel users who prize portability. The compact form, however, makes it less comfortable for extended use and provides minimal physical controls.

Control Layout and Top-Panel Design: Intuitive or Compromised?

User interface quality varied notably in my testing. Vibrant control design can accelerate workflow and creativity, especially in dynamic environments.

E-400 sports a conventional DSLR control arrangement: mode dial, dedicated shutter speed and aperture dials, and multiple customizable buttons. This layout suits photographers eager to dial in exposure manually, making it a solid educational tool for learning photography mechanics. Ergonomics here are thoughtful, with buttons positioned under natural thumb and finger paths.

Stylus 9000 eschews most physical controls beyond basic zoom and shutter buttons. Most settings are menu-driven, slowing access for advanced tweaks. This simplicity appeals to casual snapshots but limits manual control appeal for serious enthusiasts.

Sensor and Image Quality: The Heart of the Camera

Sensor characteristics largely dictate image fidelity across all photography types. Knowing their differences helps set realistic expectations.

Sensor Specs at a Glance:

Real-World Image Quality
Despite similar megapixels, the E-400's Four Thirds sensor is vastly larger, enabling bigger photodiodes for improved low-light sensitivity, dynamic range, and less noise. This translates to superior hands when shooting landscapes, portraits, and even wildlife in challenging light.

I found that the Stylus 9000’s smaller sensor struggles with noise above ISO 400, shows more compression artifacts, and lacks raw support - limiting post-processing flexibility. However, its 10x zoom compensates with versatility in framing when quality is less vital.

Display, Viewfinder, and User Interface: Visual Feedback When it Matters

A quality display and viewfinder are vital for composition and confirming settings during shooting.

Olympus E-400 uses a 2.5-inch fixed LCD with 215K resolution and a pentamirror optical viewfinder with 95% frame coverage. Though lacking electronic viewing modes, the optical finder provides true-to-life composition crucial in bright conditions, a major boon for sports and wildlife photography.

Stylus 9000 features a marginally larger 2.7-inch LCD screen with better resolution (230K) and lacks any viewfinder. Its live view is functional but limited by screen glare outdoors. The fixed lens also means zoom viewfinding relies solely on the LCD - less ideal under bright sun.

Autofocus System: Locking Focus Where It Counts

Autofocus performance directly impacts portraits, sports, wildlife, and macro success.

Olympus E-400 stands out with phase detection autofocus, providing faster and more accurate focus tracking in bright light - a decisive advantage for sports and wildlife shooting. The 3-point system is modest but responsive, especially in central areas.

Stylus 9000 relies entirely on slower contrast detect AF, which struggles with moving subjects. Performance is fine for static scenes like landscapes but limits action photography capability.

Lens and Zoom Choices: Creative Flexibility or Convenience?

Lens ecosystems amplify a camera's capabilities by addressing different styles and focal needs.

Olympus E-400 utilizes the Four Thirds mount with over 45 lenses available, from wide-angle prisms to long telephotos and macro options. This system flexibility enables photographers to grow into specialization - my favorite feature of mirrorless/DSLR hybrids.

Stylus 9000 comes with an integrated 28-280mm F3.2-5.9 zoom lens (10x range), ideal for travel shooters wanting all-in-one convenience without carrying gear. Macro focusing down to 1cm is impressive for its class but limited by fixed aperture.

Burst Rates and Shutter Speeds: Capturing the Decisive Moment

Continuous shooting and shutter performance matter for sports, wildlife, and event photographers.

Olympus E-400 offers respectable 3 fps burst for an entry DSLR, sufficient for casual sports and fauna capture. The 1/4000s shutter speed allows wide aperture use even in bright daylight.

Stylus 9000’s slower top shutter speed and unknown burst capacity limit dynamic scene capture but suffice for snapshots.

Image Stabilization: Steady Shots Without the Tripod?

With the Stylus 9000 featuring sensor-shift stabilization versus none on the E-400, this is a curious divergence.

• E-400: No in-camera stabilization - depends on stabilized lenses (not common on Four Thirds).
• Stylus 9000: Sensor-shift stabilization helps combat handheld shake, particularly useful at long zooms and low shutter speeds.

While I found the Stylus 9000’s stabilization effective for casual shooting, the E-400’s lack of it means careful handholding or tripods are advisable for low-light or telephoto use.

Flash Capabilities: Lighting Up Your Subjects

Built-in flashes have evolved but vary greatly in power and modes.

The E-400 has a more powerful native flash and supports external flashes, valuable for portraits and events where flash control and power matter. The Stylus 9000’s flash is weaker, reflecting its compact design niche.

Storage and Connectivity: Memory Matters

E-400 supports both Compact Flash and xD Picture Cards, offering versatility (and cost options since CF cards remain common). USB 2.0 connectivity is basic but functional.

Stylus 9000 accepts xD cards, microSD cards, and even offers internal storage, a rare convenience for quick backups or emergencies. However, no Wi-Fi or Bluetooth in either camera means tethered transfer only.

Battery Life and Build Quality: Trusting Your Gear in the Field

Neither camera boasts official battery life figures, but based on personal experience:

• Olympus E-400’s larger battery and DSLR design typically yield more shots per charge, suitable for professional work.
• Stylus 9000’s small compact form leads to fewer shots per charge but lighter carry weight.

Both lack environmental sealing or rugged features, so avoid harsh conditions.
