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.

Dimensions 122 x 69 x 34 mm 115 x 72 x 42 mm
Weight (body only) 369 g 334 g
Grip Moderate ergonomic grip Minimal, sleeker body
Top plate controls More extensive dials Simpler control layout

Olympus E-P3 vs Olympus E-PL1s size comparison

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.

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.

Olympus E-P3 vs Olympus E-PL1s Screen and Viewfinder comparison

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.

Feature Olympus PEN E-P3 Olympus PEN E-PL1s
AF system Contrast-detection, 35 points Contrast-detection, 11 points
Face detection Yes Yes
Continuous AF Yes Yes
AF tracking Yes Yes

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.

Feature Olympus PEN E-P3 Olympus PEN E-PL1s
Max continuous shooting 3 fps 3 fps
Max shutter speed 1/4000 sec 1/2000 sec
Shutter type Mechanical Mechanical

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.

Feature Olympus PEN E-P3 Olympus PEN E-PL1s
