Olympus E-PL1s vs Sony DSC-H20: A Hands-On Comparison for Every Photographer's Needs

As someone who has spent over 15 years immersed in the evolving world of digital cameras - from ultra-compact point-and-shoots through to pro-level mirrorless systems - I know how puzzling it can be to navigate the sea of options available to photography enthusiasts. Today, I'm diving into an in-depth comparison between two cameras from slightly different worlds, yet often considered by those on a budget or beginning their photography journey: the Olympus PEN E-PL1s, an entry-level mirrorless with Micro Four Thirds heritage, and the Sony Cyber-shot DSC-H20, a versatile fixed-lens compact zoom camera. Both launched around the same early 2010s era, these models offer distinct approaches to image-making and portability.

Having personally tested thousands of cameras in varied shooting conditions, I aim to demystify which features truly matter and how these two cameras stack up across diverse photography genres and real-world scenarios. This article will walk you through core specifications, technical performance, ergonomic design, and who should seriously consider each camera.

Let's get started.

Stepping Into the Cameras: Size, Feel, and Handling

Before pixel peeping images, handling a camera is an essential first step in determining its suitability. Photographic creativity often starts with how comfortable and intuitive the device feels in your hands.

Here, the Olympus E-PL1s embraces a classic rangefinder-style mirrorless design, offering a relatively compact but still noticeably larger body compared to the Sony H20’s ultra-portable compact form-factor. The E-PL1s measures 115 x 72 x 42 mm and weighs 334 grams, while the Sony DSC-H20 is smaller at 107 x 69 x 47 mm and lighter at 250 grams.

What does this mean practically?

• The Olympus’s larger size accommodates a more substantial grip, physical dials, and direct controls. For extended periods outdoors capturing landscapes or portraits, I found it less fatiguing and more stable - especially when attaching any Micro Four Thirds lenses, which tend to be a bit bigger.
• The Sony felt ultra-light and pocket-friendly for street photography or casual travel but lacked the ergonomic advantages for serious handheld shooting over longer sessions.

The trade-off between portability and control is critical here. For those who value freedom of movement and minimal gear, the H20’s compact footprint is appealing. For anyone focused on learning manual exposure or lens adaptability, the E-PL1s’s form-factor encourages a more engaged shooting experience.

Top Panel Controls: Hands-On Usability Insights

Ergonomics extend to control layout, and the top plate often dictates how quickly you can adjust settings on the fly.

The E-PL1s features dedicated mode dials with tactile, well-sized buttons, including Manual, Aperture Priority, Shutter Priority, and Program modes. Physical of exposure compensation dial and playback buttons round out this user-focused interface. From my experience, these controls enable confident manual shooting without fumbling through menus.

On the other hand, the Sony H20’s control scheme is simplified, reflecting its compact class. While it offers manual exposure settings, access requires more menu diving. The zoom lever, flash control, and shutter button are reachable but smaller, less satisfying for prolonged shooting sessions. There’s no physical mode dial; instead, you rely on the multi-function control wheel.

For photographers prioritizing speed and hands-on adjustment, the E-PL1s is far superior. Beginners or casual shooters less inclined to manual settings might find the Sony’s streamlined controls adequate.

Sensor Technology and Image Quality: The Heart of the Matter

At the core of any camera lies the sensor - the primary driver of image quality. Without getting too technical, let me break down how the Olympus and Sony compare here.

• Olympus PEN E-PL1s sports a 12MP Four Thirds CMOS sensor measuring 17.3 x 13 mm, with a sensor area around 225 mm². This sensor size places it in the Micro Four Thirds category, significantly larger than typical compact cameras. A larger sensor means better light capture, improved dynamic range, and lower noise - critical for image quality, especially in low light.

• The Sony DSC-H20 uses a smaller 10MP 1/2.3" CCD sensor roughly 6.17 x 4.55 mm, just 28 mm² in area. While 10MP is respectable, the tiny sensor fundamentally limits light-gathering ability, dynamic range, and low-light performance.

Real-world implications:
During my tests, I noticed the E-PL1s produced crisper, more detailed images with richer colors and smoother gradations from shadows to highlights. The Olympus also handled higher ISOs (up to 6400) fairly gracefully for an entry-level body - noise was controllable up to ISO 800, usable at 1600 with some post-process noise reduction. Shadow recovery was noticeably better given the sensor’s dynamic range capabilities.

In contrast, the Sony’s images were decent in bright daylight but suffered quickly in low light or shadows, showing stronger noise and banding past ISO 400. Its CCD sensor also meant less flexibility for post-processing RAW files (in fact, the Sony does not support RAW capture).

If image quality and editing freedom matter, particularly for portraits, landscapes, or creative work, the Olympus sensor is the clear winner.

Viewing and Framing: Screens, Viewfinders, and Interfaces

Composing your shot accurately is fundamental. Both cameras eschew built-in viewfinders, instead relying on LCD screens.

The Olympus E-PL1s has a 2.7-inch fixed HyperCrystal LCD with anti-reflective coating and 230k resolution. Despite modest pixel counts by today’s standards, the screen is clear and bright enough to frame shots outdoors, though visibility can be challenging under harsh sunlight.

The Sony H20 boasts a slightly larger 3-inch fixed LCD, also at 230k resolution, and its glossy screen delivers decent viewing angles. However, reflections tended to challenge clarity in bright light.

Both cameras lack touchscreens and electronic viewfinders, which limits their usability in bright outdoor environments and for shooters who prefer eye-level framing.

From a user interface standpoint, the Olympus provides more granular manual control menus accessible via directional buttons, while the Sony offers a simpler user interface more geared toward point-and-shoot UX.

For extended use or serious composition, I leaned towards the Olympus’s screen and controls, but compact users will appreciate the Sony's slightly larger display.

Autofocus Systems and Performance in Real-World Conditions

Focus accuracy and speed are pivotal, especially for action, wildlife, and event photographers.

• The Olympus E-PL1s features a contrast-detection AF system with 11 selectable focus points, including face detection and tracking. It supports Continuous AF and Single AF modes, enabling flexibility. In my testing, the E-PL1s's autofocus locked on consistently in good lighting, with decent tracking for portrait and static subjects. Low light AF performance was satisfactory but occasionally hunted.

• Meanwhile, the Sony H20 utilizes a 9-point contrast AF system but lacks continuous autofocus and face detection. It only offers Single AF mode. This impacted my experience in fast-moving or dynamic scenes, where focus lag was noticeable. The H20’s macro mode (down to 2 cm) shines for close-ups, but AF speed was comparatively modest for action shots.

Ultimately, the Olympus outperforms the Sony in focus versatility and speed - not surprising given its interchangeable lens heritage and more modern AF algorithms.

Burst Rates and Continuous Shooting: Capturing the Moment

If you shoot sports, wildlife, or kids in motion, burst shooting performance is critical.

The E-PL1s shoots at 3 frames per second (fps) continuous, allowing limited but usable burst sequences. I found it capable of capturing decisive moments if exposure and focus locked quickly.

The Sony H20’s burst speed is 2 fps, which felt sluggish in comparison. Coupled with slower AF, I struggled to catch fast action or multiple frames of fleeting moments.

Neither camera caters to professional sports photographers, but Olympus provides a modest edge for enthusiasts interested in moderate action capture.

Lens Compatibility and Ecosystem: How Far Can Your Creativity Go?

An essential advantage of mirrorless cameras is lens versatility. The Olympus PEN E-PL1s uses the Micro Four Thirds mount, giving access to a robust ecosystem of over 100 native lenses, ranging from ultra-wide corners to telephoto zooms, primes, macro, and specialty optics.

This flexibility lets you tailor your kit for portraits with creamy bokeh, landscapes with edge-to-edge sharpness, or wildlife with long reach. Interchangeable lenses translate to investing in your photographic growth.

Conversely, the Sony DSC-H20 sports a fixed 10x optical zoom lens ranging from 38-380mm equivalent (F3.5-4.4), a versatile all-in-one zoom for casual shooting. The macro capability extends to 2 cm, good for flower or close-up work. However, you’re locked into a single lens with all its limitations (aperture range and optical quality).

If you foresee growing your creative horizons, the Olympus’s Micro Four Thirds system offers unparalleled flexibility relative to the Sony's fixed lens.

Video Capability and Multimedia Features

Although neither camera targets video enthusiasts, let’s see what they offer for casual movie makers or vloggers.

Both cameras shoot HD video at 1280x720p and 30 fps and 640x480 at 30 fps. Video quality is adequate for snapshots and basic documentation.

• The Olympus E-PL1s uses Motion JPEG format, lacks microphone and headphone jacks, and offers no advanced video stabilization. Its focus tracking during video is basic but functional.

• Similarly, the Sony H20 records 720p video, lacks external audio input, and relies on optical image stabilization built into the lens, which helps smooth hand shake.

Neither model includes 4K, log profiles, or advanced codecs, so serious videographers will find these limited.

Durability and Weather Sealing: Taking Your Camera Outdoors

For landscapers, travel photographers, and outdoor adventurers, weather sealing and durability matter.

Both the Olympus E-PL1s and Sony H20 lack environmental sealing features. Neither is dustproof, waterproof, or shockproof.

Given their lightweight, plastic-and-metal constructions, care in the field is essential - avoid rain or harsh conditions without protective covers or bags.

Battery Life and Storage: Managing Power and Memory

Longevity per charge means less downtime, especially on travel or long shoots.

• The Olympus E-PL1s uses a proprietary BLS-1 lithium-ion battery, rated for around 290 shots per charge (CIPA standard). In practice, I found battery life modest but sufficient for casual use - carrying spares is wise for extended days.

• The Sony H20 lacks detailed battery rating information publicly, but typical compact camera expectations apply (often shorter than interchangeable lens systems). The H20 uses the NP-BG1 battery.

Storage-wise, Olympus supports SD/SDHC cards, the industry standard, while the Sony uses Memory Stick Duo/Pro Duo cards in addition to internal memory - bearing in mind Memory Sticks are less common and more expensive today.
