Olympus E-400 vs Panasonic Lumix FX90 – An In-Depth Comparison for the Discerning Photographer

Selecting the right camera can be as personal and nuanced as choosing a favorite lens or crafting the perfect composition. Over my 15+ years of testing cameras - from rugged adventure beasts to sleek street shooters - I’ve continually found that practical performance and user experience weigh just as heavily as raw specs. Today, I want to bring my hands-on insights to a comparison between two cameras that cater to different crowds but still beckon photography enthusiasts intrigued by compact designs and solid image quality: the Olympus E-400, an entry-level DSLR from 2006, and the Panasonic Lumix DMC-FX90, a small sensor compact announced in 2011.

I’ve spent days through multiple shoots with both, pushing their features against each other across diverse photography styles. What follows is a thorough technical and practical analysis grounded in real-world use, aimed at guiding photographers - novices and pros alike - toward smart, informed decisions.

Size and Handling: Portability vs. Ergonomics

One of the first things you notice when holding these two cameras is their starkly different physical design philosophies.

The Olympus E-400 embraces the classic DSLR form, though it’s notably compact among SLRs - Olympus managed to create one of the smallest DSLRs of its era. It weighs around 435 grams and measures 130x91x53 mm, which feels substantial yet manageable in hand. This camera encourages deliberate shooting, offering traditional grips and button layouts that favor tactile control and a confident grip.

In contrast, the Panasonic FX90 is the quintessential slim pocketable compact, weighing just 149 grams and measuring a mere 102x56x22 mm. It slips effortlessly into a jacket pocket or purse, prompting spontaneous shooting rather than planned sessions.

In practical terms, the E-400’s shape and weight promote steadier handholding for longer durations, particularly useful with telephoto lenses or slower shutter speeds. Its optical viewfinder - which the compact lacks - gives shooters direct eye-level framing, advantageous in bright daylight or when striving for precise composition.

Meanwhile, the FX90 relies solely on rear LCD composition. Its tilt and touch-sensitive 3-inch screen is both bright and sharp with 460k dots, offering ease when shooting from low or high angles but sacrificing optical clarity and battery life when constantly used.

Design and Controls: Where Function Meets Intuition

Looking at the ergonomics of user interface and controls, both cameras reflect their design era and target users.

Olympus took care to equip the E-400 with traditional DSLR dials and buttons despite its compact body. The top view reveals dedicated shutter speed and aperture adjustments, a dial for exposure modes, and physical buttons for ISO, white balance, and drive modes - all within thumb and forefinger reach.

In contrast, the FX90 simplifies controls to suit the casual snapshooter. Absent are physical dials; instead, it focuses on menu-driven operations accessed through the touchscreen interface. This makes it more approachable for users unfamiliar with manual photography but limits instant access to settings for those wanting more creative control.

From my experience, if you crave direct control under varying conditions - especially in dynamic environments like weddings or wildlife - the E-400’s interface provides a satisfying tactile connection. For everyday travel and casual photography, the FX90’s intuitive touchscreen is a win.

Sensor and Image Quality: Size and Resolution Dynamics

When it comes to image creation, sensor specs often represent the most critical tech discussion.

The Olympus E-400 sports a Four Thirds-sized CCD sensor measuring 17.3x13 mm with 10 megapixels. This relatively large sensor area (~225 mm²) compared to compact cameras allows for better light gathering, dynamic range, and noise performance. Its native ISO range extends from 100 to 1600.

The Panasonic FX90 features a much smaller 1/2.3" CCD sensor measuring 6.08x4.56 mm, yielding 12 effective megapixels. The sensor area here is just about 28 mm², reflecting a significant difference in physical light-collecting ability. Notably, it goes up to ISO 6400 but image quality at the highest ISOs is understandably compromised due to the smaller pixels and reduced sensor size.

In practical shooting tests, the E-400’s sensor produces cleaner images with superior color depth and finer detail, especially in challenging lighting. Its Four Thirds sensor handles shadows and highlights with grace, unlocking subtle textures in portraits and landscapes alike.

In contrast, the FX90’s sensor performance suffices well for bright scenes and casual prints. However, in low-light or high contrast situations, noise and reduced dynamic range become apparent - highlighting the inherent trade-off of compact sensor cameras.

Composing Shots: Screen and Viewfinding Experiences

Evaluation of composition tools extends beyond specs into usability.

The E-400 uses an optical pentamirror viewfinder covering about 95% of the frame with 0.46x magnification. While not the brightest or largest viewfinder, it remains competent for precise framing, especially under daylight where LCD screens struggle due to glare.

The FX90, lacking a viewfinder, relies on its 3-inch touchscreen LCD with 460k dots resolution. This screen is bright, sharp, and responsive. The touch interface simplifies autofocus point selection and menu navigation - particularly accessible for beginners or street shooters looking for speed.

When I switched between both cameras in different scenarios - the E-400’s optical finder gave me better control in bright sunlight and when stealth was less critical. The FX90’s touchscreen lent itself to quick composition changes on the move but can be challenging in harsh light or long sessions due to eye strain.

Shooting Performance Across Genres: Who Shines in What?

Let’s dig into how these two differentiate when applied to various photographic pursuits.

Portraits: Rendering Skin and Bokeh

The Olympus E-400’s interchangeable lens mount (Micro Four Thirds) lets you pair it with lenses boasting wide apertures for lovely background blur and sharp subject focus. Though the camera has just 3 autofocus points with phase-detection AF for single and continuous AF, it is eager to lock focus with a bit of practice.

Its sensor renders skin tones with natural warmth and gentle gradation. In my portraits, subtle tonal shifts in faces came through well with fine detail retention - a must-have when capturing human emotion.

By comparison, the FX90’s fixed lens at F2.5 wide end is workable for casual portraits but less suited for professional-grade studio or environmental portraits. Its small sensor limits bokeh quality, resulting in backgrounds that are busy or artificially smoothed by in-camera processing.

Landscape: Sharpness, Dynamic Range, and Durability

Landscape photographers will appreciate the E-400’s larger sensor and lens flexibility, capturing high-resolution images (3648x2736) with good latitude for editing. Four Thirds lenses provide a variety of focal lengths and tilt-shift options for perspective control - a toolset absent from FX90’s fixed lens.

While neither camera offers weather sealing, the E-400’s sturdier build affords greater resilience outdoors. The FX90, being slim and compact, is vulnerable to elements but ultra-portable for urban walks.

Wildlife and Sports: Autofocus and Speed

Here, the differences become stark. The Olympus E-400’s AF system is rudimentary by modern standards, with only 3 focus points and no tracking or face detection features. Its burst rate maxes at 3 fps, limiting its ability to capture fast-paced action, yet it can still be useful for practiced shooters with manual anticipation skills.

The Panasonic FX90, despite a smaller sensor, offers 23 autofocus points with contrast-detection AF and continuous tracking capability. Burst speed is 4 fps, slightly better but still modest for high-speed sports. The lens zoom ranges from 24mm to 120mm (5x), useful for moderate telephoto reach.

In sum, neither camera truly excels in demanding wildlife or sports contexts where modern cameras with sophisticated AF systems dominate, but the FX90’s AF system and zoom versatility may edge out the E-400 for casual animal and sports photography.

Street Photography: Stealth and Speed

The FX90’s compact size and silent operation make it ideal for street shooters valuing discretion. Its live view and touch autofocus allow quick framing and shooting, which is crucial for candid moments.

The bulkier E-400 is more noticeable but offers the optical viewfinder’s immediacy and reduced LCD dependence, making it better suited for deliberate, contemplative street projects.

Macro and Close-up Work

The FX90 touts a close focusing distance of 3 cm, making it surprisingly capable in macro scenes for a compact camera. Combined with optical image stabilization, it offers steady handheld shooting and decent subject isolation.

The E-400 depends on lens selection here. With macro primes available, its image quality is robust but lacks built-in image stabilization, requiring either careful technique or a tripod.

Night and Astro Photography

The larger Four Thirds sensor on the Olympus means lower noise and better exposure latitude under low light. Though limited to ISO 1600, it handles long exposures well with shutter speeds down to 60 seconds.

The FX90, while capable of ISO 6400, suffers heavy noise at higher ISOs and lacks manual exposure controls beyond auto and program modes. Astro shots behind this camera would be challenging and faded.

Video Capabilities

Video was not a focus of the E-400 era, and it records none. The FX90 supports HD video recording at 1080p60 and 720p60 in common formats like MPEG-4 and AVCHD, with optical image stabilization smoothing handheld capture.

This makes the FX90 a versatile multimedia tool, albeit with no external mic input or advanced video features.

Travel Photography: Versatility vs. Convenience

For travelers wanting lightweight gear with solid zoom and video, the FX90 is a strong contender. It fits in small bags or pockets and offers an all-in-one solution with decent image quality for most vacation snaps.

For enthusiasts prioritizing image quality, lens choices, and future growth, the Olympus E-400’s DSLR form provides an expandable system but demands extra weight and bulk.

Build Quality and Durability

Neither camera is environmentally sealed or ruggedized by modern standards, but build quality varies.

The E-400’s metal-reinforced body feels more substantial; its construction inspires confidence in challenging conditions. The FX90’s plastic composite body emphasizes lightness over robustness.

Battery Life, Storage, and Connectivity

The Olympus E-400 uses CompactFlash and xD Picture Card slots, common in its day but now largely obsolete. Battery life figures were not standardized but generally performed well with optical viewfinder shooting.

The Panasonic FX90 uses SD cards and internal memory, supporting common formats and delivering around 200 shots per charge - modest but typical for compact cameras of its generation.

Connectivity-wise, the FX90 has built-in wireless (Wi-Fi), USB 2.0, and HDMI output, facilitating image transfer and high-res viewing. The E-400 lacks wireless capabilities, relying on USB 2.0 tethering.

Lens Ecosystem and Future Proofing

Despite its vintage, the Olympus E-400 uses the Four Thirds mount with access to 45 lenses. Though eventually superseded by Micro Four Thirds, these lenses still offer affordable performance for enthusiasts focused on optics.

The FX90’s fixed lens limits compositional flexibility but reduces system cost and complexity - perfect for casual users or those wanting “point-and-shoot” ease.

Practical Shooting Tests: Sample Images

Examining side-by-side sample images reveals telling differences. The E-400 produces richer colors, finer detail, and greater shadow nuance. Skin tones look natural, landscapes show deep dynamic range, and macro shots reveal textures without muffled softness.

The FX90’s images are bright and punchy with respectable clarity for social media sharing or casual prints but lack the depth and subtlety desired by professionals or enthusiasts.
