Olympus E-520 vs Sony Cyber-shot DSC-H55: A Hands-On Camera Comparison for the Curious Photographer

Choosing the right camera can often feel like navigating a jungle of specs, marketing fluff, and personal aspirations. Today, I’m diving into a side-by-side comparison of two intriguingly different cameras from the late 2000s/early 2010s era: the Olympus E-520, a Micro Four Thirds DSLR released in 2008, and the Sony Cyber-shot DSC-H55, a 2010-era small sensor compact camera. At first glance, these two may seem like an apples-to-oranges match - one’s a DSLR, the other a compact fixed-lens - yet this contrast sparks a rich discussion on their practical strengths, weaknesses, and suitability for a variety of photographic pursuits.

With over 15 years deeply immersed in camera testing, I’ve thrown countless cameras through their paces - from studio portraits to wildlife chases and starry skies. Let’s embark on a detailed exploration of these cameras’ design, tech, real-world usability, and how they stand in today’s context. Along the way, I’ll share my personal takes, quirks noticed in hands-on use, and help you understand which camera might fit your photographic vibe - whether you’re a budget-minded enthusiast, casual shooter, or niche specialist.

First Impressions: Size, Design, and Ergonomics

One of the first differences you’ll notice coming from the pocket or smartphone is each camera’s physical presence. Olympus’s E-520 is a classic Compact SLR with a traditional DSLR shape, weighing in at 552 grams with dimensions of 136x92x68 mm. The Sony H55, in contrast, is a lean little compact at just 200 grams and sized 103x58x29 mm - easy to stash anywhere.

When you handle the Olympus E-520, it feels like a solid, purposeful tool designed for hands-on shooting. Its grip offers a reassuring hold for one-handed use, which is especially important in genres like sports or wildlife where stability counts. The compact Sony H55 is nimble and pocketable, tempting for casual street shooters or travelers who prize discretion.

Moving beyond size, the top panel layout offers another clue into each camera’s intended user. The Olympus sports a traditional DSLR array of controls, including dedicated mode dials, shutter speed, aperture priority, and exposure compensation - all indicative of serious exposure control.

The Sony H55’s top controls are minimal by comparison - devoid of manual exposure modes, reflecting its fixed-lens compact lineage. For those who love twiddling aperture rings or shutter speeds, the E-520 wins hands down here. But if simplicity and point-and-shoot convenience top your list, the H55’s straightforward buttons minimize complexity.

Sensor and Image Quality: The Heart of the Matter

Let’s get technical for a moment, because sensor size and technology markedly impact image quality, dynamic range, and noise control. The Olympus E-520 sports a Four Thirds 17.3 x 13 mm CMOS sensor measuring 224.9 mm² with a resolution of 10 megapixels. The Sony H55 is equipped with a tiny 1/2.3” CCD sensor - just 6.17 x 4.55 mm, or 28.07 mm² - pumping out 14 megapixels.

If you’re mathematically inclined, you’ll immediately see the Olympus sensor is almost 8 times larger in surface area - a decisive advantage for image quality, especially in low light and wide dynamic range situations. This is reflected in DxOMark scores where the Olympus E-520 achieves overall 55 points with excellent color depth and dynamic range, while the Sony H55’s sensor and raw performance weren’t even tested by DxO, indicating its more modest imaging pedigree.

What does this mean in real life? The E-520’s CMOS sensor delivers cleaner images, better tonal gradations, and greater flexibility in post-processing. The Sony H55’s CCD sensor can be punchy in daylight conditions but struggles above ISO 400 or in shadows, with noise becoming more noticeable and dynamic range limited.

Below are sample images taken with each camera under varied conditions. While the Sony’s images are surprisingly sharp and detailed for such a small sensor, the Olympus’s photos showcase richer colors and smoother highlight roll-off.

The Screen and User Interface: How You See Your World

Both cameras employ fixed LCD screens (no articulating or touchscreen functionality) around the same resolution (230k dots), but the Sony’s 3” display edges out the E-520’s 2.7” screen in size, offering a marginally better preview experience.

In actual use, the E-520’s screen is perfectly sufficient for framing and reviewing images, but the real advantage comes from its optical pentamirror viewfinder with 95% coverage - a feature the Sony lacks entirely. For photographers who like to work eye-to-camera and avoid the sometimes inconsistent daylight visibility of LCDs, the Olympus’s viewfinder is an essential asset.

The Sony H55’s complete reliance on the LCD means outdoor brightness challenges its visibility - something I frequently spotted on bright days during street and travel shoots. The user interface on the Olympus is, as expected, more complex but more satisfying to experienced shooters, featuring manual exposure control, customizable settings, and more precise focus area selection.

Autofocus and Focusing Flexibility: Critical in Fast-Moving Moments

Autofocus performance remains a pivotal consideration - especially in sports, wildlife, and macro photography where split-second focus can make or break a shot.

The Olympus E-520 sports a hybrid autofocus system combining contrast-detection and phase-detection with 3 focus points (multi-area and selective modes) and face detection support. The Sony H55 relies exclusively on contrast-detection autofocus with 9 points but lacks face or eye detection.

In practice, the E-520 delivers more reliable and quicker focus acquisition. Its phase-detection system excels in good light and continuous shooting modes, offering some tracking albeit limited by only 3 points. The Sony, while peppy in single AF mode, sometimes hunts more in lower light or complex scenes due to its reliance on contrast detection alone.

Continuous autofocus (AF-C) further highlights the gap: E-520 can track moving subjects albeit with some limitations, while Sony’s H55 only supports single AF, making continuous shooting of unpredictable action more challenging.

Performance in Diverse Photography Genres

Portrait Photography

Portrait photography demands accurate skin tones, pleasing bokeh, and reliable eye focus. The Olympus E-520’s larger sensor and interchangeable lens system allow for shallow depth-of-field effects to naturally isolate subjects. The in-body image stabilization helps keep images sharp during slower shutter speeds common in indoor portraits. Its face detection autofocus is a modest but useful aid.

Sony H55’s small sensor yields deeper depth of field resulting in images that retain more background detail. Bokeh is minimal even at telephoto focal lengths, so isolating a subject requires more creativity with backgrounds and lighting.

Landscape Photography

For landscapes, resolution, dynamic range, and weather resilience come to the fore. The Olympus E-520’s sensor size and higher dynamic range allow capturing highlight-and-shadow detail in tricky sunlight scenarios better than the Sony. Although the Olympus lacks weather sealing, its sturdier build fares better in the field.

The Sony’s superzoom range (25-250mm equivalent) is handy for framing different landscape compositions on the go, but the small sensor limits image quality for large prints or detailed cropping.

Wildlife and Sports Photography

For wildlife and sports shooters, autofocus speed, burst rates, and telephoto reach rule.

The Sony H55 boasts a 10x optical zoom lens (25-250mm equiv.) and a burst rate of 10fps - faster than the Olympus’s modest 4fps. However, the Olympus can swap to dedicated telephoto lenses designed for these genres with better optics and faster, more accurate autofocus.

Moreover, the Olympus’s phase-detection AF and image stabilization provide an advantage for capturing fleeting moments, despite the slower continuous shooting frame rate.

Street and Travel Photography

Here the Sony H55’s compact size and zoom versatility give it a portability edge, perfect for candid shooting and travel adventures. The Olympus, while compact by DSLR standards, is still bulkier and heavier.

Lightweight enthusiasts or those valuing discretion and fast accessibility will favor the H55. However, the E-520’s better low-light sensor and optical viewfinder contribute to superior image quality and framing reliability.

Macro Photography

Neither camera offers dedicated macro modes as performance highlights, but the Sony H55 has a close focus distance of 5cm allowing decent macro shots. The Olympus’s interchangeable lenses can include dedicated macro optics with higher magnification and sharper detail, giving it clear macro advantages.

Night and Astro Photography

The E-520’s CMOS sensor, higher ISO ceiling (native up to 1600), and better dynamic range aid night and astrophotography - capturing star trails and low-light scenes more cleanly. The Sony H55 maxes out at ISO 3200 but suffers from noise sooner, limiting its utility in challenging light.

Video Capabilities

Neither camera breaks new ground in video. The Sony H55 offers 720p video at 30fps - respectable for its class at the time - while the Olympus E-520 offers no video recording capabilities. For videographers, neither camera meets modern user expectations.

Professional Workflow and Reliability

The Olympus E-520 shoots RAW files and features extensive manual controls necessary for professional workflows and editing latitude. Plus, its support for compact flash and xD cards provides flexible, reliable storage.

Sony H55 shoots JPEG only with no RAW support, limiting post-processing. Its memory card compatibility is broad but more focused on convenience than speed or reliability.

Build Quality, Weather Resistance, and Durability

Neither camera offers weather sealing or ruggedized construction. The Olympus feels more robust due to its DSLR chassis, while the Sony’s plastic compact shell is more delicate, mirroring its point-and-shoot DNA.

Battery Life and Storage Options

The Olympus E-520 recorded an exceptional battery life of 650 shots, powered by a dedicated battery pack. The Sony H55 uses the NP-BG1 battery but official battery life figures are not quoted; in real use, it tends to be more modest - a typical trade-off for small compacts.

Storage-wise, the Olympus offers compatibility with Compact Flash and xD Picture Cards; the Sony supports Memory Stick Duo/Pro Duo and SD/SDHC cards, reflecting different ecosystems and availability considerations.

Connectivity and Extras

Neither model provides wireless connectivity, Bluetooth, NFC, or HDMI outputs - expected given their vintage. Their USB 2.0 interfaces are primarily for file transfer rather than tethered shooting.
