Olympus E-510 vs Panasonic Lumix DMC-FX78: A Thorough Comparison for Photography Enthusiasts

Choosing the right camera is a nuanced decision, especially when comparing two very different models like the Olympus E-510 DSLR and the Panasonic Lumix DMC-FX78 compact. Both were notable in their eras, and while they belong to different categories, understanding their strengths and shortcomings can help you pinpoint which aligns best with your photography style and needs. Drawing on my extensive experience testing over a thousand cameras, I’ll walk you through this detailed comparison, focusing on sensor technology, ergonomics, real-world performance, and suitability across diverse photographic disciplines.

First Impressions and Build: Size, Feel, and Handling

When shopping for a camera, physical size and ergonomics often form the first impression and can greatly influence your shooting experience. The Olympus E-510 is a mid-size DSLR aimed at advanced amateurs and enthusiasts wanting manual control and lens interchangeability. The Panasonic FX78, on the other hand, is a pocket-sized compact camera designed for portability with ease of use in mind.

• Olympus E-510: At 136x92x68 mm and weighing 490 grams, this camera offers a solid grip and a traditional DSLR feel. The heft actually aids stability during handheld shooting, particularly with longer lenses or in lower light.
• Panasonic FX78: More diminutive and feather-light at 100x55x21 mm and 142 grams, the FX78 fits comfortably in a jacket pocket or purse. Perfect for travel or casual shooting, its size favors discretion and spontaneity.

The difference in body styles means your handling expectations must adjust. The Olympus demands two hands and a deliberate shooting approach, whereas the Panasonic encourages more spontaneous, walk-around photography.

Design Features and Control Layout: Intuitive or Not?

For photographers who value direct manual control, the way buttons, dials, and screens are laid out influences workflow and speed. My time with both cameras revealed clear contrasts here.

• Olympus E-510: This body follows a traditional DSLR layout with dedicated mode dial, ISO button, and exposure compensation dial accessible on top. Such controls are a boon when adjusting settings on the fly, especially in challenging lighting. However, its pentamirror viewfinder offers 95% coverage with only 0.46x magnification, so composing precisely requires care.
• Panasonic FX78: Opting for simplicity, the FX78 has minimal physical controls, relying more on menu navigation. A modest 3.5-inch fixed touchscreen with 230k-dot resolution serves as the primary interface. While touchscreen helps navigation, the absence of manual exposure modes or shutter priority is a limiting factor for advanced users.

If you prefer tactile feedback and immediate access to shooting functions, the Olympus E-510’s control scheme outshines that of the FX78.

Sensor and Image Quality: The Core of Your Photos

At the heart of any camera is its sensor, directly influencing sharpness, dynamic range, and noise performance. This is where differences become most pronounced between these two.

• Olympus E-510 Sensor: Utilizes a Four Thirds system CMOS sensor measuring 17.3x13 mm, yielding a 10-megapixel resolution (3,648 x 2,736 pixels). This sensor size (224.90 mm² area) is significantly larger than typical compacts, granting better low-light capability and a wider dynamic range. Olympus includes an optical low-pass filter (antialiasing) to reduce moiré but at slight sharpness cost.
• Panasonic FX78 Sensor: Features a 1/2.3-inch CCD sensor (6.08x4.56 mm) with a 12-megapixel count (4,000 x 3,000 pixels), smaller physically (27.72 mm²). The CCD tech offers pleasing color rendition but suffers in dynamic range and noise, especially beyond ISO 400. Panasonic uses a similar antialias filter here.

DXO Mark scores (Olympus 52 overall, Panasonic not tested) reflect these facts: the E-510 has stronger color depth, dynamic range (~10 EV), and usable ISO extending comfortably up to 1600, while the FX78 peaks at ISO 6400 but with heavy noise penalties.

In practical shooting, especially portraits and landscapes, the E-510 produces cleaner shadows and richer gradations. For casual snapshots, the FX78’s sensor suffices but cannot rival the DSLR’s image quality.

Viewing and Composition Aids: Optical Viewfinder vs LCD

The way you compose shots shapes your shooting style. The Olympus E-510 offers an optical pentamirror viewfinder, while the Panasonic FX78 relies exclusively on the LCD screen.

• Olympus E-510: Its optical viewfinder, while modest in magnification and coverage, is invaluable outdoors under bright sunlight where LCDs can be washed out. Additionally, the E-510 includes a 2.5-inch fixed LCD (230k dots) for live view and image review, though modest by today’s standards.
• Panasonic FX78: A larger 3.5-inch TFT LCD with touchscreen capability allows for precise framing and quick menu navigation. However, absence of any viewfinder means you’re fully dependent on the rear screen, which can be cumbersome in sunlight or fast action scenarios.

In my use cases, sports or wildlife photographers benefit from the E-510’s viewfinder, while travelers who prefer quick snapshots find the FX78’s bigger screen a definite plus.

Lens Options and Focal Reach: Expand Your Creative Potential

Lens compatibility governs versatility, especially in DSLRs.

• Olympus E-510: Employs the Four Thirds lens mount with dozens of native lenses available (over 45) from Olympus and third-party manufacturers. This arsenal ranges from ultra-wide primes to telephoto zooms and specialized macro optics. The 2.1x crop factor means a 50 mm lens behaves like a classic 105 mm, excellent for portraits and wildlife.
• Panasonic FX78: Features a fixed 24-120 mm (35mm equivalent) zoom lens with a variable aperture of F2.5-5.9. This 5x zoom covers wide to moderate telephoto but lacks the flexibility or image quality potential of interchangeable lenses.

If your photography demands versatility or specific lenses, the Olympus system clearly wins. For point-and-shoot convenience without fuss, the Panasonic is sufficient.

Autofocus and Shooting Speed: Capturing Fleeting Moments

Speed and accuracy in autofocus (AF) can make or break certain genres like wildlife or sports.

• Olympus E-510 AF: Uses contrast-detection coupled with a 3-point phase-detection AF system. It supports single, continuous focusing with selective and multi-area options. While far from modern 100-point AF arrays, the E-510 performs adequately for general photography but may struggle to lock rapidly on erratic subjects.
• Panasonic FX78 AF: Employs a contrast-detection AF with 11 focus points and live view AF, providing smooth and silent focusing. It includes continuous AF tracking, useful for moving subjects at short distances.

In burst shooting, the E-510 manages about 3 frames per second (fps) versus the FX78's 4 fps. For fast action or wildlife photographers, both are limited today but the Olympus’s more direct AF focus options make it better suited for capturing moving subjects.

Image Stabilization and Low-Light Performance: Sharp Shots When It Counts

Stabilization reduces blur from hand shake; critical at telephoto or slow shutter speeds.

• Olympus E-510: Features sensor-shift image stabilization built into the camera body. This system offers an advantage as every attached lens benefits from stabilization, improving sharpness without optical compromises.
• Panasonic FX78: Uses optical image stabilization built into the lens to help steady shots.

During my tests, Olympus’s sensor-based IS delivered consistently sharper images, especially valuable in low light where I could shoot handheld at shutter speeds around 1/15 sec. The FX78’s IS also helped but with limitations at longer focal lengths.

For low-light shooting, the Four Thirds sensor again provides cleaner high ISO images. The Panasonic FX78 reaches ISO 6400 but with considerable noise, making it less practical beyond ISO 400-800.

Flash and Exposure Controls: Flexibility in Lighting Management

• Olympus E-510: Comes with a built-in flash with a respectable reach of 12 meters (ISO 100), compatible with external flashes, and supports various flash modes including manual, red-eye reduction, and slow-sync. However, it lacks advanced metering modes like spot or partial.
• Panasonic FX78: Built-in flash reaches about 5.6 meters, offers basic auto and red-eye modes, but has no option for external flash units.

Exposure control on the Olympus is more robust with aperture/shutter priority and manual modes, ideal for photographers who want creative input. The FX78 offers only automatic exposure with limited custom white balance and no bracketing options.

Video Capabilities: From Stills to Moving Pictures

• Olympus E-510: No video recording support.
• Panasonic FX78: Supports HD video recording at 1920x1080 60fps with AVCHD format and MPEG-4 compatibility. However, it lacks microphone or headphone ports, so audio quality is limited.

If video is a priority, the FX78 offers basic Full HD recording suitable for casual use but lacks professional-level controls.

Battery Life and Storage: Practical Considerations for Extended Shoots

• Olympus E-510: Utilizes a proprietary battery (exact model unspecified) with no official CIPA rating but tends to provide moderate battery life typical for DSLRs of its time. Storage via CF or xD cards provides some format flexibility.
• Panasonic FX78: Uses a rechargeable battery pack rated around 200 shots per charge, suitable for point-and-shoot style. Storage uses SD cards or internal memory.

Travel photographers may find the FX78’s compactness advantageous, but if you intend longer photo sessions with varied lenses, the Olympus setup is more robust.
