Olympus E-PL7 vs Sony H55: An In-Depth Comparison for Photography Enthusiasts

Comparing the Olympus PEN E-PL7 and Sony Cyber-shot DSC-H55 is a bit like putting a fine mirrorless kitchen knife next to an all-in-one Swiss Army blade. Both have their charm, and both answer distinct user needs - but understanding where each shines requires a careful walk through their features, performance metrics, and how they behave in real shooting scenarios. I’ve spent ample time with each camera, dissecting their capabilities across multiple photography disciplines, and this detailed examination is designed to help you make a confident, practical choice.

Let’s dive in.

Getting Acquainted: Body, Design, and Handling

Ergonomics and control layout are foundational to how a camera feels during use, and both cameras address this differently due to their categories - the Olympus is a rangefinder-style mirrorless, and the Sony is a typical compact fixed-lens shooter.

The Olympus E-PL7’s dimensions of 115x67x38mm and weight of 357g place it firmly in the lightweight mirrorless rangefinder camp. In practice, this translates into solid ergonomics with a modest grip, comfortable for prolonged handheld use. Its 3-inch tilting touchscreen with high resolution (1037k dots) is an asset, especially for composing at tricky angles - a boon for street or macro shooters who like creative framing. The touchscreen interface is responsive, augmenting traditional physical controls without overwhelming the user. This blending suits enthusiasts exploring manual modes or quick adjustments on the fly.

By contrast, the Sony H55 is a smaller, more pocket-friendly compact (103x58x29mm, 200g). It’s designed for grab-and-go convenience, where bulky gear is a liability. However, this size payback is seen in control complexity: no manual exposure modes, lack of touchscreen capability, and minimal customizable buttons. The fixed lens and small battery also underscore its “point-and-shoot” ethos, ideal for casual users or travelers looking for something ultra-portable without fuss.

Comparing top views confirms this divergence in approach. The Olympus provides a comprehensive control layout with dials and buttons suited for customizability and quick access. The Sony’s simpler landscape focuses on automated shooting modes - no surprises here, reflecting their design goals.

Verdict on handling: The E-PL7 caters to active photographers who value tactile controls and manual operation, while the H55 prioritizes ease and portability at the cost of depth.

Sensor and Image Quality: The Heart of Photography

Jumping into the image-capture core, sensor technology marks the most significant divide.

Olympus employs a 17.3x13mm Four Thirds CMOS sensor with 16MP resolution. While smaller than full-frame, it offers a great balance between size, resolution, and noise control when paired with TruePic VII processing. The Olympus sensor supports RAW files and gifts us a native ISO range of 100 to 25600, providing flexibility in both bright daylight and more challenging low-light conditions.

On the flip side, Sony’s H55 uses a tiny 1/2.3" CCD sensor (6.17x4.55mm) with 14MP resolution. As a small-sensor compact, it inherently faces limitations in dynamic range, noise performance, and high ISO capabilities. It maxes out at ISO 3200 with no RAW support, restricting post-processing versatility.

Testing under varied lighting confirmed expectations: Olympus produces richer color depth (22.7 bits vs. Sony’s untested but understood to be lower bracket), broader dynamic range (12.4 EV vs. markedly compressed shadows and highlights on the H55), and superior noise control at elevated ISOs - critical for night, event, or indoor photography.

The Olympus’ antialias filter does mildly soften fine detail but is a classic trade-off for moiré reduction without seriously compromising sharpness. Sony’s small sensor, combined with a CCD readout, tends to exhibit noise and less detail in shadow areas, impacting landscape or wildlife shots where tonal gradation matters.

In sum: For image quality, the Olympus E-PL7 decisively outruns the Sony H55, thanks to a physically larger sensor and more advanced imaging pipeline.

Viewing and Composing: Screens and Viewfinders

Looking through - or rather, at - your composition tools affects framing precision and user comfort.

Olympus continues to impress with a 3" 1037k-dot tilting touchscreen LCD, supporting intuitive touch-to-focus, menu navigation, and even selfie modes. The tilting mechanism seriously broadens creative shooting angles - high, low, and everything in between.

Sony’s H55 sticks to a fixed 3" LCD but with a significantly lower resolution (230k dots). The lack of touchscreen means reliance on buttons for AF point selection and settings adjustments, which feels dated and sluggish, especially in live view mode.

Neither camera includes a built-in electronic viewfinder (EVF), though the Olympus supports optional external EVFs. For outdoor bright-light shooting, the Olympus’ screen visibility holds up better, partially because of higher resolution and anti-reflective coatings.

Bottom-line: Olympus is better suited for photographers who demand flexible, precise composition tools. The Sony’s screen, while adequate for instant snaps, limits prolonged or professional use.

Autofocus System and Focusing Performance

Autofocus is notoriously complex territory, and here the mirrorless Olympus and compact Sony diverge considerably.

The Olympus E-PL7 boasts 81 contrast-detection focus points and an advanced face detection system, including continuous AF and tracking modes. Manual focus is supported, along with touch focusing on the screen, providing comprehensive options for different subjects.

Sony H55 is simpler, with 9 contrast-detection points, no face or eye detection, and a fixed AF system. Manual focusing is not supported, which restricts creative control in macro or selective focus applications.

In real-world fast-moving subjects - such as street or wildlife shooting - Olympus’ continuous AF and tracking abilities make a noticeable difference, consistently locking onto faces or moving targets accurately. The Sony struggles with latency and occasional hunting, especially in dim light.

Olympus' touch-to-focus combined with eye-detection enhanced portrait accuracy, a feature missing entirely from the Sony.

Summary: If your photography involves moving subjects or requires precise manual focus, Olympus is the clear winner.

Burst Shooting and Speed

Burst rate influences the ability to capture fleeting moments, crucial in sports and wildlife.

The Olympus E-PL7 manages eight frames per second in continuous shooting - respectable for an entry-level mirrorless. This burst rate supports short sequences, good for sports or kids’ action shots when paired with fast SD cards.

Sony H55 claims 10 frames per second in a much lower-resolution JPEG burst - but due to simpler processing and smaller files, it’s equally limited by buffer size and can’t sustain long bursts. Plus, the lack of continuous AF support means many frames can be out of focus when tracking a subject.

Olympus’ more sophisticated processor and autofocus system enable better overall responsiveness, making it a more dependable tool for dynamic shooting environments.

Lens Ecosystem and Optical Performance

Olympus’s use of the Micro Four Thirds mount is a masterstroke for versatility. The system boasts over 100 native lenses including primes and zooms from Olympus, Panasonic, and other third-party manufacturers. This flexibility opens doors to specialized glass for portraits (fast f/1.2-1.4 primes), landscapes (sharp wide angles), macro, and telephoto.

Sony H55’s fixed 25-250mm equivalent lens (f/3.5-5.5) caters to convenience but at a premium - compromises on optical sharpness at extremes of zoom, limited aperture range, and no swap options.

This optical flexibility with Olympus is a massive advantage for professionals or enthusiasts who want to focus on specific genres without investing in the full-frame price tier.

Video Capabilities: Shooting Moving Images

When it comes to video, neither camera is designed to be a videographer’s first choice, but they do provide basic options.

Olympus E-PL7 offers Full HD 1080p at 30 frames per second, encoded in H.264. While it lacks advanced codecs, log profiles, and microphone inputs, the E-PL7’s in-body stabilization aids handheld footage smoothness. Unfortunately, no headphone jack limits audio monitoring.

Sony H55 caps at 720p HD video, again at 30 fps, and records in MPEG-4. No optical or digital stabilization during video review, meaning more pronounced shake in handheld clips. Also lacks external audio support.

For casual video use, Olympus again stands ahead - better resolution and stabilization contribute to cleaner-looking results.

Battery Life and Storage

Despite its compact size, the Olympus E-PL7 delivers approximately 350 shots per charge using the BLS-50 battery, which is decent but not extraordinary. This is expected in mirrorless cameras due to the constant electronic viewfinder/screen use and sensor power draw.

Sony H55’s battery life isn’t explicitly rated in our official specs, but small sensor compacts often offer comparable or slightly better shot counts due to simpler electronics and no EVF.

Both cameras take a single memory card - Olympus uses SD/SDHC/SDXC cards, while Sony accepts Memory Stick Duo family and SD cards, a point of compatibility consideration.

Connectivity and Extras

Olympus packs built-in Wi-Fi, enabling quick image transfer and remote control via smartphone apps - a notable usability feature for travel or fast sharing.

Sony H55 lacks any wireless connectivity, meaning reliance on cables for data transfer.

Olympus also includes function bracketing modes (AE, WB), timelapse recording, and sensor-based stabilization, enhancing creative options.

Sony’s built-in flash modes cover the basics, whereas Olympus requires an external flash - a nod toward Olympus users favoring dedicated lighting systems for professional work.
