Olympus E-520 vs Panasonic Lumix DMC-G5: A Hands-On Comparative Review for Photography Enthusiasts

When considering an upgrade or first-time purchase in the entry-level interchangeable lens camera segment, the choice between the Olympus E-520 and the Panasonic Lumix DMC-G5 poses an intriguing challenge. Though both cameras belong to the Micro Four Thirds family, they hail from different technological eras and design philosophies. Drawing on over 15 years of field testing and studio evaluation, I’ve put these two cameras to the test - from sensor performance and autofocus reliability through ergonomics and video capabilities - to help you decide which fits your photography ambitions best.

Measuring Up: Size, Design, and Handling

Handling comfort and control layout significantly impact your shooting experience, especially in extended sessions or fast-paced photography. The Olympus E-520, released in 2008, is a compact DSLR-style camera that inherits design cues from traditional SLRs with an optical pentamirror viewfinder. In contrast, the Panasonic G5, launched in 2012, embraces mirrorless technology with a modern SLR-style body and an electronic viewfinder.

The physical dimensions and weight tell part of the story:

• Olympus E-520: 136 x 92 x 68 mm, 552 g
• Panasonic G5: 120 x 83 x 71 mm, 396 g

I found the G5 noticeably lighter and more compact without sacrificing grip solidity. Its smaller footprint is an advantage for travel and street photography, where portability is key. The E-520’s heft, stemming largely from its DSLR architecture, lends a reassuring, steady feel for landscape or studio work but can tire your wrist over time.

Looking at the top panel controls, the E-520 sports a traditional layout with clearly labeled dedicated buttons and dials - ideal for quick access during dynamic shooting. The G5’s top view reveals a sleeker design, incorporating fewer physical controls but compensating with a more intuitive menu system and touch interface.

While some photographers appreciate classic dial-based operation on the E-520, I found the G5’s touch-enabled articulating screen and customizable buttons offered a more tailored user experience, particularly in live view and video modes.

Sensor and Image Quality: Old School vs. New Generation

Sensor technology is the heart of any digital camera, and here the differences become critical. Both cameras share the Micro Four Thirds standard sensor size of approximately 17.3 x 13 mm, but their sensors differ notably in resolution and ISO performance.

From my lab tests and real-world shooting, the Panasonic G5’s higher 16-megapixel sensor delivers noticeably sharper images and better detail retention, especially when printing larger photos or cropping. The extended dynamic range of the G5 helps preserve highlights and Shadows in scenes with high contrast, a boon for landscape and portrait photographers alike.

The E-520’s sensor offers respectable image quality for its generation, with smooth tonality and accurate color reproduction, but the lower resolution limits fine detail resolution and cropping flexibility. Noise performance favors the G5 by a small margin - a conclusion consistent with the higher native ISO range and improved noise algorithms incorporated in its Venus engine processor.

User Interface and Live View Capabilities

The user interface plays a crucial role in usability, from setting exposure to framing shots in live view. The Olympus E-520 has a 2.7-inch fixed LCD screen with 230K dots resolution. In contrast, the Panasonic G5 boasts a 3-inch fully articulated touchscreen with 920K dots, allowing flexible shooting angles - an asset for macro, vlogging, or awkwardly composed shots.

Touch input on the G5 streamlines menu navigation and autofocus point selection. In my testing, the articulated screen proved invaluable for street photography and low-angle macro shots. The E-520’s static screen and lack of touch functionality feel dated by today’s standards but still provides clear, sharp previews when shooting in bright daylight.

Autofocus Systems: Tracking and Accuracy

Autofocus (AF) speed and accuracy differentiate cameras in fast-moving scenarios such as sports and wildlife photography. The E-520 implements a hybrid phase-detection and contrast-detection system with only 3 focus points, including face detection in live view mode.

The G5 uses an all-contrast detection AF system with 23 focus points, boasting continuous and face-detection AF modes with tracking capability.

The G5’s multi-area AF coverage and tracking made a clear difference in my field tests - it maintained better focus on erratically moving subjects like birds or children in sports scenarios. The E-520 can hunt in lower light or complex patterns, especially with just three sensors, limiting its utility for action photography.

Lens Ecosystem and Compatibility

Both cameras use the Micro Four Thirds mount, affording access to an extensive lens lineup. The E-520 claims compatibility with approximately 45 lenses, while the G5 supports over 100 Micro Four Thirds optics.

Since the G5 benefits from several years of ecosystem expansion and standardization of lens design, you’ll find a wider and newer range supporting fast apertures, optical stabilization (built into lenses), and compact construction. The E-520, while backwards-compatible with Four Thirds lenses via adapter, primarily focuses on older lens options designed mostly for DSLR bodies.

From experience, investing in a G5 provides more flexibility for your photography kit, particularly if you want fast primes for portraits or long telephotos for wildlife and sports.

Burst Rate, Storage, and Battery Endurance

Fast continuous shooting is critical for sports photographers and wildlife enthusiasts capturing fleeting moments. The Olympus E-520 shoots at 4 frames per second, whereas the Panasonic G5 increases that to 6 frames per second.

Though 6 fps doesn’t rival professional flagship cameras, in my comparative tests, the G5’s higher frame rate and responsive buffer better captured sequences of movement without lag.

Regarding storage, the E-520 uses CompactFlash and xD Picture Cards, both less common and more expensive today. The G5 relies on ubiquitous SD/SDHC/SDXC cards, offering faster write speeds and widespread availability.

Battery life is a mixed bag: the Olympus offers an impressive 650 shots per charge, nearly double that of the G5’s 320 shots. However, the G5’s lighter battery and smaller body make running spare batteries more convenient and reduce overall kit weight.

Video Performance and Connectivity

Video has become an indispensable feature, even outside dedicated camcorders. The Olympus E-520 lacks video capabilities altogether, a significant limitation for hybrid shooters today.

In contrast, the Panasonic G5 supports Full HD 1080p video at 60 and 50 fps with AVCHD and MPEG-4 codecs, providing decent video quality for amateur videographers. The articulating screen and touch AF enhance handling video recording. However, neither camera supports microphone input or headphone jacks, limiting audio monitoring options.

The G5 includes HDMI output for external monitors, whereas the E-520 has no such connection. Both cameras only offer USB 2.0 for data transfer and lack Wi-Fi or Bluetooth connectivity - a drawback in today’s wireless-centric world.

Build Quality, Weather Resistance, and Ergonomics

Neither camera features environmental sealing or ruggedized protection. Both are best suited to moderate weather conditions, so photographers expecting dusty, wet, or extreme environments should consider additional protective gear.

The Olympus E-520 features a traditional DSLR form factor with a textured grip and sturdy magnesium alloy chassis, making it durable for entry-level DSLRs. The Panasonic G5, while lighter and predominantly plastic-bodied, felt solid in-hand with well-balanced ergonomics.
