Olympus PEN E-P3 vs Olympus PEN E-PL1s: An In-Depth Comparison for the Discerning Photographer

When it comes to mirrorless cameras that blend classic rangefinder aesthetics with modern digital technology, Olympus’ PEN series has been a stalwart choice. Today, we take a detailed look at two entry-level Micro Four Thirds mirrorless cameras from Olympus: the Olympus PEN E-P3 (announced August 2011) and the Olympus PEN E-PL1s (announced November 2010). Although released just months apart, these models serve somewhat different niches within the entry-level rangefinder-style mirrorless category.

Having personally tested and used hundreds of cameras over 15 years, including dozens of Olympus models, I’ll unpack the real-world differences in performance, design, sensor capabilities, usability, and suitability for various photographic disciplines. This exhaustive comparison steers clear of marketing fluff to focus on practical insights that will help you pick the best camera for your needs and budget.

Feeling It in Your Hands: Design, Size, and Ergonomics

When evaluating cameras, physical handling is one of the first criteria I test. The Olympus PEN E-P3 and E-PL1s share the classic rangefinder-style mirrorless design signature to the PEN line, but with notable differences in size, weight, and control layout.

Why size and grip matter:
For extended shooting sessions or for photographers with larger hands, the E-P3’s slightly larger and chunkier build offers more comfortable handling and better tactile feedback. The E-PL1s is more compact and lighter, making it ideal for travelers or street photographers who prioritize portability.

In my hands-on tests, the E-P3 felt better balanced, particularly with larger zoom or prime lenses. The E-PL1s, while pocket-friendly, requires a more deliberate grip, and its thinner body means you may occasionally worry about grip security - something you may want to factor into your decision.

Top View and Control Interface: How Intuitive is the Experience?

The control layout greatly impacts how quickly and efficiently you can change settings on the fly - a critical element in genres like street or wildlife photography.

• Olympus PEN E-P3: Comes with a dedicated mode dial, aperture and shutter speed dials, and customizable buttons. This setup gives more manual control with fewer menu dives - a big plus for photographers comfortable with manual exposure modes and quick adjustments.
• Olympus PEN E-PL1s: Offers a more simplified interface with fewer physical controls, relying more heavily on menus accessed via the rear LCD. This can slow down operability when shooting fast-paced action.

In field tests, especially shooting sports and wildlife where rapid changes are common, the E-P3’s tactile controls won hands-down. Beginners may prefer the E-PL1s layout, but if you want a more immediate manual control experience, the E-P3 excels.

Sensor and Image Quality: Breaking Down the Core

Both cameras use a 12MP Four Thirds CMOS sensor but differ in image processor generation and some performance nuances.

Image quality in practice:
The E-P3’s newer TruePic VI processor delivers improved noise handling, dynamic range, and overall image sharpness, especially above ISO 1600. I found the E-P3’s files cleaner at higher ISOs, making it better suited to low-light and indoor photography.

Dynamic range is slightly better on the E-P3, allowing more detail recovery in shadows and highlights during post-processing. This advantage benefits landscape and professional work where maximum tonal range is important.

While both cameras produce sharp, detailed images with good color fidelity and natural skin tones, the E-P3 edges out in technical quality due to processing improvements, making it the preferable choice for photographers who prioritize image quality.

Viewing and Live View Experience

Live view and the rear LCD are your windows to composing and reviewing shots. Their quality and usability impact usability profoundly.

The E-P3’s 3" OLED touchscreen delivers superior resolution and better visibility in bright conditions, alongside improved color reproduction and contrast. Its touchscreen capability, while basic, enhances menu navigation and focusing speed through touch AF – a welcome convenience.

In contrast, the E-PL1s’ lower-resolution LCD feels outdated by today’s standards, making critical focusing and image review less precise. The lack of touchscreen means slower menu navigation.

Autofocus: Speed, Accuracy, and Face Detection

The autofocus (AF) system’s prowess is decisive for genres involving motion, such as wildlife, sports, street, and even candid portraiture.

The E-P3’s increased number of AF points (35 vs 11) translates to noticeably faster and more accurate focus acquisition. During tests photographing fast-moving subjects like cyclists and birds in flight, the E-P3’s AF locked faster and maintained focus more reliably.

Face detection works well on both but responds faster and more accurately on the E-P3, making it better suited for portrait photographers focusing on eye sharpness. Neither model supports phase-detection AF or animal eye AF - a limitation to bear in mind for serious wildlife shooters.

Burst Shooting and Shutter Performance

Burst mode performance is crucial for action photography. Both cameras offer continuous shooting at about 3 frames per second.

The E-P3’s faster maximum shutter speed (1/4000s vs 1/2000s) allows more flexibility when shooting wide aperture lenses in bright light or capturing fast action without overexposure.

The burst rate is modest by modern standards but adequate for casual sports and street photography. I tested both in fast action scenarios and found the buffer depths similar, though the E-P3’s faster shutter helps freeze motion better.

Video Capabilities: What You Can Capture

While neither camera is designed as a video powerhouse, video specs contribute to overall versatility.

The E-P3 offers full HD 1080p recording at 60 fps, giving smoother and more professional-looking videos. In contrast, the E-PL1s tops out at 720p at 30 fps, which limits video quality and flexibility.

Despite lacking external mic inputs, the E-P3’s video quality and stabilization make it the better choice for casual videographers reflecting an industry trend toward hybrid still/video functionality even in entry-level cameras.

Battery Life and Storage

Shooting duration and storage options can influence a photographer’s experience on long shoots or travel.

A modest improvement here: the E-P3’s newer BLS-5 battery generally delivers longer shooting times, reducing the frequency of battery swaps in the field. Both cameras use single card slots with broadly compatible SD standards.

If you anticipate heavy use in remote locations, consider carrying spare batteries for either camera.

Build Quality and Weather Resistance

Neither camera offers weather sealing or ruggedized build, which is common at this price and era. Both are constructed primarily of plastic and magnesium alloy components.

These cameras require careful handling in adverse conditions. I advise investing in a good quality protective case and lens covers if shooting outdoors in rain or dust.

Lens Ecosystem and Compatibility

Both cameras use Olympus’ Micro Four Thirds lens mount, supporting a broad range of lenses - over 100 official options amply cover every genre from weddings to wildlife.

This compatibility offers immense flexibility with native Olympus and third-party optics from Panasonic, Sigma, Tamron, and Voigtländer. The 2.1x crop factor means a 25mm prime behaves like approximately 50mm on full-frame - traditionally suitable for portraits and everyday shooting.

Choosing lenses depends more on your photographic genre; both cameras will handle nearly any MFT lens, but the E-P3’s better autofocus makes it more effective with telephoto zooms critical for wildlife and sports.
