Olympus E-PL1s vs Panasonic GX7: A Thorough Hands-On Comparison for Photography Enthusiasts

Having spent over 15 years shooting and testing a wide variety of mirrorless cameras, the Olympus PEN E-PL1s and Panasonic Lumix GX7 occupy fascinating chapters in the story of Micro Four Thirds system evolution. While both cameras share the same sensor size and lens mount, their generational gap - 2010 vs 2013 - means they cater to notably different user demands and technical expectations.

In this detailed comparison, drawn from my extensive experience in real-world shooting across multiple genres, I’ll explore all critical aspects: from sensor and image quality to ergonomics, autofocus, video, and specialist uses like macro or astrophotography. My aim is to support your decision-making with practical insights into how these cameras perform both technically and creatively.

Let’s begin by positioning them physically and visually.

Seeing Them Side by Side: Size, Build, and Ergonomics Matter

When you pick up a camera, how it feels in your hands can influence your creativity as much as any spec sheet. The Olympus E-PL1s is an entry-level mirrorless designed for casual shooters advancing from compact cameras or DSLRs. It sports a compact, rangefinder-style body that’s feather-light at 334 grams and roughly 115x72x42 mm in size.

The Panasonic GX7, announced three years later, steps into the advanced mirrorless category with a larger 123x71x55 mm body, weighing 402 grams. It’s more robust and offers a more substantial grip, attractive to enthusiasts who want more control and better handling during intensive shooting sessions.

Ergonomically, the GX7’s more pronounced grip and carefully positioned dials deliver a more confident handling experience. The E-PL1s’s minimalistic design is easy to carry all day but less optimized for rapid operation or heavy telephoto lenses.

Both use the Micro Four Thirds mount, giving access to the same broad lens ecosystem of over 100 lenses, but we'll dig deeper into optics compatibility later.

Control Layout and User Interface: Intuitive or Intimidating?

Fast and intuitive access to settings is a hallmark of user-friendly cameras. Here, the Panasonic GX7 shines with an evolved, thoughtful control scheme tailored for photographers who prefer manual overrides and quick setting changes.

Comparing their top plates provides revealing insights:

The GX7 features multiple dials, including a dedicated exposure compensation dial and mode dial. Its buttons are backlit, and the tilting touchscreen LCD - a feature absent on the older E-PL1s - adds significant flexibility, especially when composing at awkward angles or operating in bright sunlight.

By contrast, the E-PL1s keeps it simple with fewer manual controls, aimed at users desiring an easy plug-and-shoot experience with minimal learning curve. While this suits beginners or casual photographers, it limits options for those wishing to explore manual exposure creatively.

Sensor Performance and Image Quality: Technical Foundations of Great Photos

Both cameras use Four Thirds-sized sensors measuring 17.3 x 13 mm, but the GX7’s sensor steps up with a 16-megapixel resolution versus 12 megapixels in the E-PL1s. This translates to a maximum image resolution of 4592x3448 pixels for the GX7 compared to 4032x3024 pixels for the older Olympus.

The sensor architecture differences, combined with the improved Venus Engine processor in the GX7, deliver tangible advantages:

• Dynamic range: The Panasonic scores a DxOMark-measured dynamic range of 12.2 EV (exposing more highlight and shadow detail), whereas the E-PL1s lacks official DxO testing but is visibly more constrained in high-contrast scenes.

• Color depth: GX7’s 22.6 bits of color depth ensure richer, more nuanced tones and better grading flexibility in post-processing.

• Low-light ISO: The GX7’s native ISO tops at 25600 with a DxOMark low-light score near 718, far outperforming the E-PL1s’s 6400 max ISO and limited noise control.

Practically, I found the GX7’s files offer smoother gradients and less chroma noise from ISO 1600 upward, while the E-PL1s shines best under daylight or controlled lighting conditions.

Displays and Viewfinders: How You Frame Your Shot

The GX7’s tilting 3-inch touchscreen LCD with 1,040k dots offers significant advantages for versatile shooting angles and menu navigation - a boon for street, macro, and event photographers alike. The E-PL1s sticks with a non-touchfixed 2.7-inch 230k-dot LCD that feels dated and restrictive by comparison.

Meanwhile, the GX7 boasts a built-in electronic viewfinder (EVF) with 2.76 million dots, 0.7x magnification, and 100% coverage. This solid, high-res EVF facilitates sharp composition in all lighting, with near-zero lag. The Olympus lacks an EVF by default, requiring an optional accessory - adding bulk and expense.

From my testing, the GX7’s EVF significantly enhances shooting confidence, especially outdoors or with fast action; conversely, the E-PL1s’s reliance solely on LCD limits accuracy and usability in bright conditions.

Autofocus Systems: Speed, Accuracy, and Tracking in Real-World Action

Focusing technology is critical, especially for dynamic subjects like wildlife and sports. Both cameras implement contrast-detection AF without phase-detection pixels, typical of their era, but the GX7 improves focus points from 11 (E-PL1s) to 23, resulting in better coverage and flexibility.

Face detection autofocus is available on both, with the GX7 adding center-point AF and more sophisticated continuous tracking modes. Neither boast advanced animal eye-detection found in later models. Importantly, continuous AF tracking is smoother and more reliable on the GX7, which achieves a faster burst rate of 5 fps versus 3 fps on the E-PL1s.

In controlled testing, the GX7 locks focus quicker and maintains tracking integrity better, especially under changing light and movement patterns common in sports or wildlife.

Burst Rates and Buffer Depth: Catching Fleeting Moments

While neither camera specializes in fast-action shooting, their maximum burst speeds can influence usability for certain photographers. The GX7 shoots at 5 fps continuous burst versus 3 fps for the Olympus. Combined with a more generous buffer and faster processing, the GX7 better supports sequences requiring precise timing.

For sports photographers needing high frame rates, neither camera will replace flagship models from Sony or Canon, but the GX7 represents a solid step up in the Micro Four Thirds category.

Lens Ecosystem and Compatibility: Your Creative Playground

Both cameras utilize Micro Four Thirds mounts, offering access to an extensive selection of native lenses from Panasonic, Olympus, and third parties, spanning primes and zooms from wide-angle to super-telephoto.

Between them, the lens count is about 107 options, covering specialties such as macro, portrait, and ultra-wide. While the E-PL1s supports this full range, its lower resolution and autofocus speed somewhat limit exploiting the most demanding glass.

The GX7’s higher resolution sensor and superior AF support invite pairing with fast primes (f/1.2, f/1.4) and telephotos for professional-quality portrait, wildlife, and event shooting.

I recommend photographers consider the GX7 if planning to invest in higher-end optics for maximum image quality and versatility.

Build Quality and Weather Sealing: Durability in the Field

Here both cameras are limited to basic dust and splash protection, without formal environmental sealing or ruggedization features. Neither is waterproof or freezeproof. The GX7’s more substantial body affords a feeling of greater solidity, but neither camera is designed for extreme weather or rough handling.

Travel and outdoor shooters should consider protective gear or weather-sealed camera alternatives if working frequently in unpredictable conditions.
