Olympus E-PL1s vs Sony A58

Olympus PEN E-PL1s vs. Sony SLT-A58: An In-Depth Comparison Across Photography Genres

When it comes to entry-level interchangeable lens cameras around the mid-2010s, Olympus and Sony have both carved out tempting options for photo enthusiasts stepping up from compact cameras or smartphones. The Olympus PEN E-PL1s and Sony SLT-A58 represent two markedly different approaches to the mirrorless and DSLR formats, respectively. Having test-driven both extensively under varied shooting scenarios, I’m excited to share a comprehensive, hands-on comparison. We’ll cover everything from build and ergonomics to sensor performance, autofocus, and suitability across genres - so you can find your best fit whether you shoot portraits, landscapes, wildlife or beyond.

First Impressions: Size, Handling, and Ergonomics

Physically and in terms of feel, these cameras tell different stories in no uncertain terms. The Olympus E-PL1s embraces the compact, rangefinder-style mirrorless ethos: lightweight, neatly packaged and understated in its design. Weighing just 334 grams and measuring 115×72×42 mm, it slips comfortably into small bags or even larger coat pockets.

In contrast, the Sony A58 is a more traditional entrant-level DSLR body, larger and considerably heavier at 492 grams and bulkier dimensions (129×95×78 mm). The solid heft coupled with a prominent grip inspired confidence in handling, especially with larger lenses.

While the Olympus’s smaller footprint is ideal for street photography or travel - minimizing fatigue and drawing fewer glances - the Sony’s tactile controls and robust body lend themselves better to longer shoots or situations demanding steadier grips, such as wildlife or sports photography.

Looking from above highlights their diverging command schemes. The Olympus E-PL1s sports a minimalist top layout, with a mode dial and shutter release dominating the interface, reflecting its beginner-friendly focus. The Sony A58 incorporates more DSLR-style controls, including dedicated exposure compensation, and a shutter speed dial offering quicker manual adjustments on the fly.

For photographers who prioritize intuitive, tactile control over a compact size, the Sony offers more refined ergonomics, but if discreteness and portability top the list, Olympus fits the bill nicely.

Sensor Technology and Image Quality: Micro Four Thirds vs. APS-C

At the heart of any camera comparison is the sensor, dictating not only resolution but critical aspects like dynamic range, noise performance, and color depth.

The Olympus E-PL1s uses a 12-megapixel Four Thirds CMOS sensor measuring 17.3×13 mm (224.9 mm²). The smaller sensor size means a 2.1x crop factor, impacting lens field of view and depth of field characteristics. The sensor is paired with the TruePic V image processor, which was fairly advanced at its launch but shows age compared to more modern chips.

Sony’s A58 sports a notably larger APS-C sensor at 20 megapixels (23.2×15.4 mm, 348 mm²) with a 1.6x crop factor. The larger sensor area translates into inherently better low light and dynamic range capabilities. DXOMark benchmarks validate this: A58’s color depth scores 23.3 bits vs. Olympus’s untested but expectedly lower range; dynamic range at 12.5 EV vs. Olympus untested; and low-light ISO performance reaching an effective 753 ISO points for Sony.

The Sony’s sensor offers a clear technical advantage that manifests in richer images with more detail retention in shadows and highlights, especially notable in high-contrast or low-light conditions.

For landscape and portrait photographers who value fine tonal gradation and high-resolution output, the Sony’s APS-C sensor is preferable. Micro Four Thirds enthusiasts may appreciate Olympus’s sensor for its characteristic color signature and greater depth of field at equivalent focal lengths.

Viewfinders and LCD Screens: Composing the Moment

Neither camera features an optical viewfinder like DSLRs of yore, but both manage to provide framing assistance.

The Sony A58 includes a 1440-pixel-resolution electronic viewfinder with 100% coverage and 0.65x magnification - relatively sharp and lag-free compared to early EVFs. This offers a clear advantage for composing action or wildlife shots in bright conditions where LCD screens can be barely visible.

In contrast, the Olympus E-PL1s lacks a built-in EVF and relies on its fixed 2.7" HyperCrystal LCD with anti-reflective coating. The screen is low resolution (230k dots) and fixed, which constrains composing from rare angles. The absence of an EVF does limit usability in strong sunlight or for fast shooting.

The tilt and superior resolution of Sony’s tiltable 2.7" LCD (460k dots) further enhance framing flexibility, especially for macro or vlogging styles. This makes the A58 more versatile when precise framing is critical.

Autofocus: Precision vs. Speed

Autofocus (AF) performance often distinguishes cameras between snapping casual portraits and nailing moving wildlife or sports shots. Both cameras have contrast-based systems but with different technologies underpinning them.

Olympus E-PL1s employs contrast detection with 11 points and face detection but lacks phase-detection AF. It performs well in controlled or static scenes but struggles with fast subjects or low contrast.

Sony’s A58 introduces an innovative Translucent Mirror Technology enabling phase-detection autofocus with 15 points (3 cross-type), resulting in considerably faster and more reliable AF tracking. This performs especially well for moving targets and continuous focus modes.

Continuous shooting rates echo this: 3 fps on the Olympus vs. a more aggressive 8 fps on the Sony. Thus, for wildlife or sports photographers who need to track and capture fleeting moments, Sony’s autofocus and burst speeds confer a noticeable advantage.

Lens Ecosystem and Focal Length Coverage

Lens compatibility extends the creative potential of your camera choice.

Olympus E-PL1s uses the Micro Four Thirds mount with a selection of 107 native lenses. These compact, often affordable lenses benefit from the smaller sensor but multiply the focal length by 2.1x, turning a 25mm prime into about a 50mm field of view.

Sony’s A58 uses Sony/Minolta Alpha mount lenses, with 143 available options ranging from consumer to semi-professional glass. The 1.6x APS-C crop means somewhat wider coverage compared to Olympus for the same focal lengths.

Both systems have robust zoom and prime options, but Sony’s extensive lens lineup, including third-party support, may appeal more to photographers wanting telephoto reach (sports, wildlife) or specialized lenses (macro, tilt-shift).

Battery Life and Storage

One practical consideration I always assess is battery endurance in the field.

The Olympus E-PL1s offers roughly 290 shots per charge - modest by today’s standards but typical for mirrorless bodies of its time.

The Sony A58 impresses with 690 shots per charge, more than twice the Olympus, making it very appealing for travel, events, or long wildlife outings where charging opportunities may be limited.

Both use standard battery packs (BLS-1 for Olympus and NP-FM500H for Sony) and store images on SD/SDHC cards - though Sony adds support for Memory Stick Pro Duo and SDXC, lending flexibility.

Image Stabilization and Flash

Both cameras feature sensor-based image stabilization, aiding in handheld shooting by compensating camera shake. This is excellent to see, especially on entry-level models.

Built-in flashes are present on both; each offers around 10m synchronous flash range with customizable flash modes. The Sony’s external flash compatibility and microphone input for video make it more adaptable to advanced flash setups.

Video Capabilities

While neither camera is a dedicated video powerhouse, Sony’s A58 decisively outperforms Olympus in this realm.

The Olympus E-PL1s records HD video at 1280×720 pixels at 30 fps in Motion JPEG format - a somewhat outdated codec with larger file sizes and modest video quality.

Sony’s A58 offers full HD 1080p at 30 fps with solid MPEG-4, AVCHD, and H.264 codecs, enabling crisper, more manageable files. Plus, the presence of a microphone port allows for improved audio capture with an external mic, a boon for vloggers or multimedia creators.
