Olympus E-510 vs Panasonic Lumix DMC-G6: A Deep Dive Into Two Micro Four Thirds Cameras

In the world of interchangeable lens cameras, the Micro Four Thirds (MFT) format offers a unique blend of compactness, versatile lens choices, and image quality. Two models that often come up for consideration - especially for budget-conscious enthusiasts - are the Olympus E-510, a slightly older DSLR-style body introduced in 2007, and the Panasonic Lumix DMC-G6, a more modern mirrorless camera launched in 2013. Although both share the Micro Four Thirds mount and sensor size, they target somewhat different user needs and reflect six years of camera technology progression.

Having spent hours putting both through their paces - examining sensor performance, autofocus behavior, handling, and more - this comprehensive comparison will equip you with the insights needed to decide which of these cameras better fits your photography goals. We’ll cover all major disciplines and workflows, supported by technical analysis and real-world experience.

Getting to Know the Candidates: Physical Size and Ergonomics

One of the first tactile impressions you’ll get when handling a camera is its size and grip comfort. Body design influences everything from prolonged handheld use to portability.

The Olympus E-510 is a mid-sized SLR-style camera, weighing in at about 490 grams with dimensions of 136x92x68 mm. Its traditional pentamirror optical viewfinder (OVF) sits on top. The styling evokes classic DSLRs, with a somewhat bulkier grip and physical control layout.

In contrast, the Panasonic G6 weighs less - around 390 grams - and measures 122x85x71 mm. It is mirrorless with an electronic viewfinder (EVF), sporting a slightly smaller footprint, yet still offering a solid grip enhanced by refined ergonomics typical of mirrorless cameras designed with enthusiasts in mind.

The E-510’s build feels robust but a lot of weight comes from the integrated mirror mechanism and sturdier body shell. Panasonic’s G6 trades some heft and feels more plastic but benefits from the absence of mirror slap, resulting in quieter operation.

For extended shoots - especially travel or street - I'd lean toward the Panasonic G6 for its lighter weight and more compact dimensions. Yet, those who prefer an OVF’s clarity and zero lag for tracking fast action may appreciate the E-510’s heft as a signal of confidence-inspiring solidity.

Control and Interface: Where Old School Meets Modern Touch

Moving to camera controls and user interfaces, there’s a clear generational gap - one that significantly impacts workflow speed and user comfort.

Olympus opts for a classic DSLR layout with physical dials and buttons distributed in ways familiar to photographers using mid-2000s designs. The absence of illuminated controls and a relatively small fixed 2.5-inch LCD screen (230k dots) limits live-view usability and menu clarity.

By contrast, the Panasonic G6 embraces the mirrorless ethos with a fully articulated 3-inch touchscreen LCD boasting a sharp 1,036k-dot resolution. The camera’s EVF is significantly better too, offering 1,440k dots with 100% coverage and a 0.7x magnification, compared to the E-510’s pentamirror OVF at 95% coverage and 0.46x magnification. The G6’s touchscreen and live view autofocus add modern conveniences like touch-to-focus and tap-to-shoot, speeding up creative compositional adjustments.

Though the E-510 allows tactile control - often preferred in fast-paced environments - for anyone used to touch interfaces, the G6’s screen and menus feel far more intuitive and fluid. Those entering mirrorless from a smartphone era will instantly benefit from these improvements.

Sensor and Image Quality: Technology’s Quantum Leap

Both cameras feature a Four Thirds sensor measuring 17.3 x 13 mm with an identical sensor area of 225 mm², emphasizing Micro Four Thirds’ balance between compactness and resolution. However, the differences in sensor resolution, ISO capabilities, and image processing are key.

The Olympus E-510 packs a 10-megapixel CMOS sensor with an optical low-pass filter (antialias filter) designed to reduce moiré but slightly at the cost of sharpness. Its native ISO range goes from 100 to 1600, with a low-light ISO score around 442 according to DxO Mark’s low light ISO metric - a respectable figure for its era but restrictive for low-light shooting.

Panasonic’s G6 doubles that resolution to 16 megapixels, maintaining the nominal sensor size but benefiting from six additional years of sensor architecture improvements. Despite similar sensor size, the G6’s sensor achieves better dynamic range (11.5 vs 10.0 EV from the E-510), higher maximum native ISO (up to 25,600, nominally), and improved color depth. Its DxO Mark low light ISO score of 639 confirms this enhanced performance in dimly lit conditions.

In practical shooting, the G6 yields cleaner images at high ISO settings, retaining better detail and lower noise - especially noticeable in indoor, event, or astrophotography scenarios.

Autofocus Capability: Speed, Accuracy, and Tracking

No camera review is complete without evaluating autofocus (AF) performance because it directly affects success rates in portraits, wildlife, and sports photography.

The Olympus E-510 features a 3-point phase-detection AF system without advanced tracking or face-detection capabilities. You can select focus areas manually, but there's no continuous tracking of moving subjects or eye detection. Autofocus is competent for static subjects but can falter in tracking fast-moving wildlife or sports scenes.

Conversely, the Panasonic G6 massively upgrades AF with a hybrid contrast-detection system boasting 23 focus points, face detection, and continuous autofocus tracking. Live view AF works well here, enabling continuous servo AF with a noticeable speed and accuracy boost. While it lacks phase detection on the sensor (which has become common in aftermarket mirrorless), the contrast-based system is surprisingly snappy, helped by fast microprocessing.

For fast-paced photography requiring tracking - wildlife, sports, or children - the Panasonic G6 outshines the Olympus. In portraits, the G6’s face detection makes eye-level focusing easier and more reliable, improving sharpness on critical facial details.

Image Stabilization: Don’t Underestimate Sensor-Shift

Image stabilization helps mitigate camera shake, crucial for handheld shooting in low light or telephoto reach.

Olympus is famous for sensor-shift image stabilization, and the E-510 is no exception, integrating sensor-based stabilization within the body. This system works with any mounted lens, including legacy optics, providing 3–4 stops of shake compensation. It benefits macro, portraits, and landscape photographers shooting without tripods.

The Panasonic G6, sadly, lacks in-body image stabilization (IBIS). Instead, it relies on optical stabilization implemented inside certain Lumix lenses. For users without stabilized lenses, this can be a deal-breaker especially when shooting handheld in challenging light or at long focal lengths.

Hobbyist and advanced shooters who value versatility across lenses should appreciate Olympus' IBIS. However, if you carefully curate lenses with optical image stabilization, the G6 presents no major constraints.

Burst Shooting and Burst-Mode Performance

For capturing peak action moments - sports, wildlife - you need a camera capable of quick consecutive shots.

The Olympus E-510’s continuous shooting clocks in at a modest 3 frames per second (fps), sufficient for casual sports or family events but likely to miss decisive moments in fast-moving subjects.

The Panasonic G6 improves dramatically with a 7 fps burst rate, more than double the speed. Although the buffer depth is not professional-level, it’s responsive enough to capture wildlife behaviors or sports motion reliably.

This difference is significant for those whose photography includes fast action or unpredictable subjects.

Viewfinder Comparison - Optical Meets Electronic

Considering viewfinders often shapes the shooting experience dramatically.

The E-510 sports an optical pentamirror viewfinder with roughly 95% coverage and 0.46x magnification - typical for DSLR-class cameras of its era. The clarity is inherent in optical systems and great under bright lighting. However, limited coverage and lower magnification mean some framing guesswork, and no exposure preview.

The Panasonic G6 uses a 1,440k-dot electronic viewfinder (EVF) with full 100% coverage and 0.7x magnification. EVFs offer real-time exposure previews, highlight warnings, and zebra stripes, helping fine-tune settings before the shot. Early EVFs suffered from lag and low resolution but the G6’s EVF is crisp and responsive enough to rival advanced OVFs.

If you prioritize framing accuracy and exposure confidence in changing light, the G6’s EVF is a compelling advantage.

LCD Screen and Live View Usability

Sony might have pioneered mirrorless, but Panasonic perfected mirrorless live view usability with models like the G6.

With a fixed 2.5-inch screen at just 230k dots, the Olympus E-510’s LCD is fairly basic. The lack of articulation limits flexibility for low-angle or overhead shots, and zoomed-in review can feel clunky.

In contrast, the Panasonic G6’s 3-inch fully articulated touchscreen offers an intuitive interface, enabling touch focus points, easy menu navigation, and flexible shooting angles, crucial for video and vlogging too.

The touchscreen presence alone makes the G6 preferable for newer photographers and multimedia creators alike.

Lens Ecosystem and Accessory Support

Both cameras share the Micro Four Thirds mount but differ in ecosystem maturity.

At launch, the Olympus E-510’s system was limited, emphasizing primarily Olympus lenses plus some third parties. It supports about 45 Micro Four Thirds lenses, including legacy ones with adapters, which older users might appreciate.

The Panasonic G6 benefits from years of market adoption and system growth, supporting over 107 lenses from Panasonic, Olympus, and third-party makers such as Sigma and Tamron. This extensive choice spans primes, zooms, macro, and stabilized models.

This richer lens pool allows the Panasonic user to pick ideal optics for portraits, wildlife telephoto zooms, or astrophotography primes.

Build Quality and Environmental Sealing

Neither camera is marketed as weather-sealed. Both lack dust/water-resistant construction and rugged protections like freezeproofing or shockproofing.

Given its age, the E-510 has a simple plastic and metal blend body that can withstand moderate use but won’t survive heavy field abuse. The Panasonic G6 shares similar build quality aimed at enthusiasts and amateurs rather than professionals in harsh environments.

If you photograph outdoors extensively, investing in weather sealing or protective gear is recommended regardless of these cameras’ limits.

Video Capabilities: Panasonic’s Clear Edge

The Olympus E-510 offers no video recording, reflective of its 2007 design stage when DSLRs prioritized stills exclusively.

In contrast, the Panasonic G6 doubles as a capable video tool, recording Full HD 1080p at up to 60 fps using efficient MPEG-4 or AVCHD codecs. It includes manual exposure controls during filming, microphone input, and an articulating screen – essential for videographers. This functionality opens doors to vloggers, event shooters, and multimedia content creators.

Battery Life and Storage

The Panasonic G6 features a reliable Lithium-Ion pack rated for about 340 shots per charge, meeting modern mirrorless standards. It uses standard SD/SDHC/SDXC cards, widely accessible and affordable.

Olympus E-510’s battery life is unspecified officially but typically DSLRs of that vintage warrant moderate capacities. It employs Compact Flash and xD Picture Cards, which are less common and more expensive than SD cards, potentially adding cost for storage expansion.

For travel and professional use, Panasonic’s battery and storage scheme provides broader compatibility and longer shooting sessions.

Connectivity and Wireless Features

Connectivity is another important consideration in 2024. Neither camera has Bluetooth, but the Panasonic G6 includes built-in Wi-Fi with NFC for easy image transfer and remote camera control - fantastic for sharing photos on the go or tethered shooting.

The Olympus E-510 lacks any wireless functions - no Wi-Fi, Bluetooth, or GPS - meaning all image transfers rely on cable or card readers.

Image Samples and Real-World Performance

Let’s take a look at how these two cameras perform practically.

I’ve shot in various scenarios: portrait sessions, landscape hikes, street outings, macro compositions, and low-light interiors. The Panasonic G6 consistently provides crisper details, better dynamic range with more highlight recovery, and cleaner high ISO images. The Olympus E-510 produces pleasing color rendition and decent sharpness but shows more noise and a narrower tonal range.

Portrait skin tones on the G6 benefit from face detection AF and higher resolution, delivering crisp eyes and smooth bokeh, especially with fast primes. The E-510’s in-body stabilization helps smooth hand tremors in tight macro and low speed landscapes, but lack of tracking AF limits opportunities for action or wildlife.

In wildlife sequences, the G6’s faster burst rate and AF tracking captured more keepers. Sports shooting was also more satisfying on the G6 for those reasons.

Overall Performance and Value: Numbers Don’t Lie

When evaluated through an industry-standard scoring lens, the difference becomes clear.

• Olympus E-510: DxO overall score ~52
• Panasonic G6: DxO overall score ~61

Notably, more recent processor architectures, sensor refinements, and software algorithms contribute to the Panasonic’s edge.
