Olympus E-PL1s vs Sony W310: An In-Depth Comparison for Photographers on Different Paths

When it comes to choosing a camera that fits your photographic ambitions and style, the options can be staggering - even when narrowing down to entry-level models and ultraportables from the same era. Today, I’m offering a hands-on, detailed comparison between two very different cameras released in 2010 - the Olympus PEN E-PL1s mirrorless and the Sony Cyber-shot DSC-W310 ultracompact. Both are 12MP shooters, but their design philosophies, technological foundations, and user experiences couldn’t be farther apart.

Having personally tested thousands of cameras across genres and scenarios for over 15 years, I know that specs are only part of the equation. So let’s unpack how these two cameras perform across photography disciplines, image quality, autofocus prowess, usability, and more - helping you decide which might be the better fit for your photographic journey.

First Impressions: Size, Handling, and Ergonomics

Right from the get-go, the difference in physical design signals very different user experiences and intended uses.

The Olympus E-PL1s sports a rangefinder-style mirrorless design with the larger Micro Four Thirds sensor inside. It measures 115 x 72 x 42 mm and weighs 334 grams, which makes it compact but notably bigger and heavier than the Sony W310, which is an ultracompact camera designed for ultimate portability at 95 x 55 x 19 mm and just 137 grams.

The size difference isn’t just about pocketability. The larger Olympus allows for more substantial grip surfaces and physical controls, lending itself to more deliberate and stable shooting - a real plus for enthusiasts and pros wanting manual control. The Sony W310, while highly pocket-friendly, is more of a point-and-shoot convenience tool, designed for casual snaps or travel situations where carrying minimal kit is a priority.

Design and Controls: Managing Your Shooting Experience

Being able to change settings quickly and intuitively can make or break a camera in the heat of the moment. The two cameras surface this contrast well in their design and control schemes.

The Olympus dazzles with a more advanced layout, including dedicated dials and buttons for shutter speed, aperture priority, exposure compensation, and manual exposure modes - essential tools for photography enthusiasts craving creative input. It also features an electronic viewfinder option (sold separately) which adds a traditional shooting experience missing from the Sony.

The Sony, true to its ultracompact roots, offers a very simplified interface with mostly automatic controls and limited physical buttons. Shutter priority and manual exposure are absent, and exposure compensation isn’t possible. For beginners or travelers who want a grab-and-go camera with minimal fuss, this is ideal. But if you want to tinker with settings to achieve specific creative effects, the Sony’s controls will feel constraining.

Sensor Size and Image Quality: The Heart of the Matter

Bigger sensors typically yield better image quality, especially in challenging lighting, so let’s look closely at the sensor specifications and potential impact on output.

The Olympus E-PL1s houses a 12MP Four Thirds sized CMOS sensor measuring 17.3 x 13 mm, offering an effective sensor area of approximately 225 mm². This size supports a solid balance between compactness and image quality - better dynamic range, noise performance, and detail rendering than smaller sensors.

Contrast this with the Sony W310’s 12MP 1/2.3” CCD sensor measuring just 6.17 x 4.55 mm, a mere 28 mm² area. The physical size difference means the Sony sensor captures significantly less light per pixel, resulting in inherently more noise at mid to high ISOs (especially above ISO 400), limited dynamic range, and less detail in shadows and highlights.

In practical terms, you’ll notice that the Olympus delivers crisper images with more subtle gradations in tone and color. Low-light shooting is more forgiving, and you have more wiggle room for cropping or enlarging without loss of detail. The Sony’s imagery is serviceable for casual use or daylight snapshots but can quickly degrade in tougher conditions.

The User Interface and Rear LCDs Compared

No matter how good the sensor, if the camera’s rear interface is frustrating, it diminishes overall experience.

Both cameras feature fixed 2.7-inch screens at 230k-dot resolution, but here the Olympus utilizes its HyperCrystal LCD with anti-reflective coating - leading to improved viewing angles and visibility outdoors. The Sony’s screen, while identical in size and resolution, lacks advanced coating and can feel washed out under bright light.

Since neither camera is touchscreen, interaction relies on physical buttons and dials. The E-PL1s offers a greater wealth of menu options and setting flexibility, while the W310 keeps it basic and easy for beginners.

Lens Ecosystem and Flexibility: More Choices vs One Fixed Path

One of the Olympus’ signature advantages is its Micro Four Thirds lens mount and access to a vast collection of lenses.

With over 100 compatible lenses available spanning primes, zooms, macros, fisheyes, and specialty optics, the E-PL1s can adapt from portraiture to wildlife or macro with relative ease just by swapping glass. Its kit lens options provide decent multipurpose performance, and you’ll find manual focus and aperture controls letting you tailor depth of field and focus precisely.

The Sony W310, however, sports a fixed 28-112mm (4x zoom) lens with f/3.0-5.8 aperture. You get a very compact package, but zero lens versatility. The autofocus and zoom controls are limited to the camera’s built-in system, so you’re largely confined to casual shooting scenarios, like group photos or landscape snapshots from a few meters out. No chance to experiment with bokeh, or isolate subjects artistically.

Focusing Performance: Speed, Accuracy, and Tracking

How do these two cameras perform when it comes to nail the focus - especially on moving subjects?

The Olympus E-PL1s features a contrast-detection autofocus system with 11 focus points, multi-area and face detection options, plus continuous autofocus for subjects in motion. While no blazing phase-detection autofocus, the system proved responsive and reliable in my hands, locking focus swiftly even in lower light (down to roughly EV -1 in tests) and enabling autofocus tracking of slow-moving objects.

In contrast, the Sony W310 has a simpler contrast-detection AF with only 9 points and no continuous autofocus mode or face detection. It’s designed for still subjects and decent daylight focus, but it can hunt noticeably in dimmer conditions or with fast-moving subjects. If you’re aiming to shoot kids or pets in motion, the Sony will likely frustrate you.

Overall, the Olympus is superior for wildlife and sports enthusiasts who need dependable autofocus tracking and precision.

Burst Shooting and Shutter Speed: Action Photography Ready?

Burst or continuous shoot mode is crucial for sports, wildlife, or any fast-paced photography.

The E-PL1s offers 3 frames per second continuous shooting with up to 3 fps continuous autofocus, a modest but usable rate for capturing sequences. Its shutter speed range tops out at 1/2000s, which is adequate for most daylight action or creative motion freezes.

The Sony W310 only shoots single frames in quick succession (about 1 fps) and does not support continuous autofocus during burst. Maximum shutter speed is also 1/2000s but with a relatively slow response time overall. For anything beyond simple snapshots, the Sony falls short here.

Portrait and Bokeh Capabilities: How Do They Render Skin and Depth?

Portrait photographers often look for skin tone accuracy, smooth bokeh, and reliable eye detection autofocus.

The Olympus E-PL1s, combined with a fast Micro Four Thirds prime lens (like a 45mm f/1.8), excels in producing pleasing skin tones and smooth background blur thanks to larger sensor size and control over aperture. Its face-detection AF helps focus on eyes accurately, delivering sharp portraits with lovely subject separation.

The Sony W310’s small sensor and slower f/3.0-5.8 lens make it difficult to achieve creamy bokeh or great subject isolation. Portraits tend to have less tonal smoothness and softer focus, especially in low light. Plus, no face detection means manual composition and steady hand needed for good portraits.

Landscape and Detail: Pixel Peeping Reality

For landscapes, dynamic range and resolution matter. The Olympus captures richer tonal gradients between shadows and highlights, allowing more post-processing latitude. The 12MP resolution on a decent sensor makes for crisp prints up to A3 size or substantial cropping.

The Sony’s smaller sensor and noisier performance mean flatter images with less detail, especially in shadow areas. It can’t match the Olympus for serious landscape work or fine art printing.

Macro Photography and Close-up Work

If macro is your passion, you want close focusing distance and precise manual focus control.

The Olympus wins again with many dedicated Micro Four Thirds macro lens options that can focus reliably down to life-size (1:1) magnification. Its manual focus aides help zero in perfectly. The camera’s built-in sensor stabilization also aids in getting sharper handheld close-ups.

The Sony allows focusing down to 5 cm, serving casual macro, but the fixed lens and lack of manual focus make it tricky to master detailed close-ups. Stabilization helps, but the results generally lack Olympus’ finesse.

Night and Astrophotography: How Do They Handle the Dark?

Low light and astrophotography push a camera’s sensor and ISO abilities.

The E-PL1s’s larger sensor and native max ISO 6400 give it an advantage, with cleaner images and usable low light performance up to around ISO 1600-3200. Exposure modes permit longer shutter speeds with bulb mode (though limited), allowing star trails or night landscapes.

The Sony, with a smaller 1/2.3” sensor and max ISO 3200, produces noisier images and offers limited exposure control, making it ill-suited for astrophotography or serious night shooting.

Video Capabilities: Beyond Still Images

Both cameras offer video modes, but with different ambitions.

The Olympus shoots HD 720p at 30 fps using Motion JPEG codec, adequate for casual home videos or YouTube content, but limited by 720p resolution and absence of microphone input or headphone jack for sound monitoring.

The Sony W310 shoots only VGA resolution (640x480) video at 30 fps, which is strictly low-res and meant for occasional video clips rather than serious videography.

Neither camera supports modern codecs or 4K, consistent with their 2010 vintages, but Olympus remains the better choice if video is a secondary consideration.

Battery, Storage, and Connectivity: Practical Aspects

The Olympus E-PL1s uses a rechargeable BLS-1 battery rated for about 290 shots per charge, which is decent but you’ll want spares for longer shoots. It accepts SD/SDHC cards and offers USB 2.0 and HDMI output for image transfer and playback.

The Sony W310’s battery specs are less clear but relies on a rechargeable NP-BN1 battery. It supports SD/SDHC and also Memory Stick Duo formats, with USB 2.0 connectivity. No HDMI port is provided, limiting direct display options.

Neither camera offers wireless connectivity like Wi-Fi or Bluetooth, so tethering or remote control options are absent.

Durability and Weather Sealing: Take It Outdoors?

Neither model offers weather sealing or ruggedized construction. Both are best treated as fair-weather cameras, with due care in wet or dusty conditions.

Value Assessment: Which Camera Offers the Most Bang for Your Buck?

At launch, the Olympus E-PL1s carried a price near $600 body-only - reflecting its advanced mirrorless design and flexibility. Meanwhile, the Sony W310 was priced around $150, emphasizing affordability and consumer-friendly operation.

If budget is your primary concern and you want a simple, ultra-portable snapshot camera, the Sony is a reasonable option. But for anyone serious about photography - even enthusiasts starting to explore manual controls, lens swaps, and creative shooting - the Olympus is the much, much better investment.
