Olympus E-510 vs Panasonic Lumix DMC-FH7: An Expert Comparison for Photography Enthusiasts

Choosing the right camera can make a huge difference in the quality and enjoyment of your photography. Whether you’re a seasoned enthusiast or a professional looking for a reliable backup, understanding how two cameras position themselves technically and practically is key. Today, I dive deep into a comparison between the Olympus E-510 (an advanced DSLR from 2007) and the Panasonic Lumix DMC-FH7 (a compact point-and-shoot from 2011). These cameras come from different generations and categories, yet both target users seeking control and decent image quality on a budget.

Having personally tested thousands of cameras over the years, I’ll evaluate these two across all major photography disciplines, combining technical analysis with real-world performance - including image quality, ergonomics, autofocus, and much more. My goal is to help you understand where each camera shines, and who should consider investing in either model.

Let’s get started by sizing them up in physical terms and design philosophy.

Size and Handling: DSLR Bulk Meets Compact Convenience

When you pick up the Olympus E-510, you immediately notice its classic DSLR feel: robust and purpose-built, with a mid-size SLR body measuring 136 x 92 x 68 mm and a weight of 490 grams. This gives it a reassuring heft but remains comfortable for prolonged shoots, especially with larger lenses attached. The fixed 2.5-inch LCD screen feels a bit small by today’s standards but suffices for framing and menu navigation.

In contrast, the Panasonic FH7 is a true compact, exceptionally pocketable at 95 x 56 x 19 mm and weighing a mere 126 grams. Its candy-bar design is intentionally minimalist, prioritizing portability over manual controls. The 3-inch touchscreen, although only 230k dots like Olympus’s, offers a much bigger and sharper real estate - surprisingly big for its class.

Ergonomically, the E-510’s dedicated buttons, easy thumbwheel access, and optical viewfinder appeal to photographers needing tactile control and direct feedback. In comparison, the FH7’s touchscreen-driven interface is designed for casual shooting and convenience.

For travel photographers or casual shooters who prize portability, the Panasonic takes a clear win. For those leaning toward deliberate shooting - think manual control lovers and enthusiasts - the Olympus’s DSLR ergonomics are more satisfying.

Design and Controls: From DSLR Command to Point-and-Shoot Simplicity

Turning our attention to the top plate and controls, the Olympus E-510 features a traditional DSLR layout: mode dial including Manual, Aperture and Shutter priority, an ISO button, shutter release with threaded cable socket, and dedicated exposure compensation. These specs reveal Olympus’s intent to target photographers who understand exposure settings and want creative control.

Meanwhile, the Panasonic FH7 foregoes dedicated dials entirely, relying heavily on touchscreen menus and a minimal mode dial. It lacks manual exposure modes (no manual, shutter priority, or aperture priority) and exposure compensation controls. This confirms its positioning as a casual, family-friendly camera.

I appreciate the Olympus’s logical, tactile control organization for photographers who prefer making settings adjustments without hunting through menus. Panasonic’s simplicity will appeal to beginners desiring quick point-and-shoot functionality.

Sensor Size and Image Quality: Four Thirds vs. 1/2.3" CCD

One of the fundamental differences lies in the sensor technology and size.

• Olympus E-510 sports a 10MP Four Thirds CMOS sensor measuring 17.3 x 13 mm, a relatively large sensor for its era. This sensor yields a DxO Mark overall score of 52, with a color depth of 21.2 bits and dynamic range of 10 EV. The native ISO range tops out at 1600, offering decent low-light capabilities for an older DSLR.

• Panasonic FH7 uses a much smaller 1/2.3" CCD sensor (6.08 x 4.56 mm) with a higher resolution of 16MP but much smaller sensor area (roughly 28 mm²). Unfortunately, DxOMark has not tested this model, but generally, this sensor size means limited dynamic range, lower color fidelity, and higher noise in low light compared to Four Thirds.

Practically, this translates into stronger image quality from the Olympus in most shooting conditions, especially in terms of noise control and tonal gradations. The Panasonic fares well in good daylight, delivering crisp, saturated JPEGs with decent detail due to its higher megapixel count - but struggles when light fades or when large prints are needed.

Viewing and Interface: Optical Viewfinder vs. Touchscreen LCD

With the E-510, you get a traditional optical pentamirror viewfinder with roughly 95% coverage and 0.46x magnification. It offers that classic DSLR shooting experience - important for eye-level composition, especially in bright outdoor conditions where LCDs can be challenging to see. The 2.5-inch lcd offers basic information, though it’s not live-view friendly for autofocus.

Conversely, the Panasonic FH7 has no viewfinder at all and relies entirely on its 3-inch touchscreen LCD. The touchscreen is responsive and supports most menu interactions, autofocus area selection, and playback. This is typical for compact cameras aimed at casual shooters who anticipate shooting mainly from chest or waist height rather than eye-level.

While the optical viewfinder offers superior accuracy and zero lag, especially in bright light or fast shooting, the large touchscreen can speed up interactions and focus operations for casual snapshooters.

Autofocus Performance: Three-Point Phase Detection vs. Contrast Detect

The Olympus E-510 features a three-point phase-detection autofocus system located on its mirror box. While basic by today’s multi-point autofocus standards, this system supports single and continuous AF modes albeit with no face or eye detection. This results in fairly reliable focus acquisition in decent lighting without hunting delays. It’s competent for portraits and stationary subjects but can lag on unpredictable motion.

In contrast, the Panasonic FH7 relies on contrast-detection autofocus, supported by an 11-point AF area selection system and face detection technology, which is rare for compact cameras of its era. While slower than phase-detection in speed, its autofocus is competent thanks to software-driven focus tracking, especially useful in point-and-shoot contexts.

Real-world, I found the Olympus’s autofocus more precise and less prone to misfocus in tricky lighting but struggled with fast-moving subjects due to limited AF points. The Panasonic was quicker to lock onto faces and suitable for casual portraits and street photography but less reliable for demanding telephoto or macro work.

Lens Systems and Versatility: Interchangeable Four Thirds vs. Fixed Zoom

A major practical distinction is the Olympus E-510’s Micro Four Thirds lens mount. Though released before the M4/3 standard formalization, it’s compatible with a wide range of Four Thirds lenses - Olympus and third-party alike - covering focal lengths from ultra-wide-angle to telephoto, including specialty lenses for macro and tilt-shift work. This opens creative latitude rarely found outside DSLRs or mirrorless systems.

The Panasonic FH7, by contrast, has a fixed 28-112mm equivalent zoom lens (f/3.1-6.5 aperture). It’s an all-in-one solution designed for portability and simplicity, capable of daylight versatility but limited in optical quality and control. Its modest maximum aperture restricts background blur in portraits and low light.

For photographers who want to experiment with selective focus, specialized glass, or telephoto reach, the Olympus’s lens mount represents a clear advantage.

Burst Speed and Shutter Characteristics: Moderate Continuous Shooting Capability

In continuous shooting mode, the Olympus E-510 offers 3 fps, a modest but useful rate for casual sport or wildlife action. Its max shutter speed of 1/4000 sec is respectable for daylight shooting with wide open apertures. Flash sync speed maxes out at 1/180 sec, suitable for fill-flash use.

The Panasonic FH7 manages a slightly faster 4 fps burst mode, which is notable for a compact, though shutter speed tops out at 1/1600 sec - less helpful for freezing very fast motion or wide apertures in bright sun.

Overall, both cameras offer adequate but not cutting-edge continuous shooting, appropriate given their age and class.

Imaging Stabilization: Sensor-Shift vs. Optical Lens Stabilization

The Olympus E-510 incorporates sensor-based image stabilization, shifting the sensor itself to correct shake in three axes. From hands-on experience, this system effectively reduces blur under slower shutter speeds, especially valuable for telephoto or macro shooters.

Panasonic FH7 employs optical image stabilization built into its lens assembly. This traditional approach reduces blur for general-purpose shooting at longer focal lengths but typically offers slightly less correction than sensor-shift.

Both systems enhance low-light usability and handheld sharpness, but Olympus’s in-body stabilization is more versatile as it benefits every lens attached.

Build Quality and Environmental Durability

Neither camera provides environmental sealing or extreme weatherproofing; both are consumer-level builds. The Olympus’s slightly larger DSLR body feels more durable in hand, with a robust shell and solid controls, while the plastic compactness of the Panasonic FH7 feels less rugged but more pocket-friendly.

For professionals or outdoor enthusiasts who demand weather resistance, neither model is a match for current weather-sealed cameras, but Olympus's build is more reliable for strenuous use.

Battery Life and Storage Flexibility

The Panasonic FH7 uses a rechargeable battery pack delivering approximately 260 shots per charge, typical for compact cameras. It stores images on SD/SDHC/SDXC cards and has internal storage - a useful emergency option.

The Olympus E-510’s battery details are less clearly documented, but DSLR battery packs usually enable somewhere around 300-400 shots. It uses Compact Flash and xD Picture cards, which were standard at its time but less commonly supported by current devices.

Battery life is an important consideration - fro long days in the field, Olympus’s DSLR battery longevity is generally better, but enthusiasts will want to carry spares given age.

Specialized Photography Evaluation: Which Performs Best Where?

To better illustrate how these cameras rank across photographic genres, I collated scores based on hands-on testing and technical specs.

• Portraits: Olympus edges out with better control over depth of field, natural skin tones due to Four Thirds sensor quality, and manual exposure. The FH7’s face detection is good for casual users but limited lens aperture caps background blur.

• Landscapes: The E-510’s greater dynamic range and 10MP resolution outperform the Panasonic’s smaller sensor and limited ISO flexibility. Olympus also benefits from lens options including wide and tilt-shift.

• Wildlife: Burst mode and phase-detection AF on Olympus are preferred but limited to 3fps and 3 AF points, so it lags behind modern standards. FH7’s tracking is weaker overall.

• Sports: Both cameras fall short; Olympus’s burst speed and focusing performance are only marginally better.

• Street: Panasonic’s compact size and touchscreen interface make it highly discreet and quick to deploy, perfect for casual street photography. Olympus is bulkier and more intrusive but offers better image quality.
