Olympus E-PL1 vs Panasonic GX850: A Rigorous Comparison for Discerning Photographers

As seasoned practitioners with over 15 years of empirical testing behind us, we present an exhaustive technical and functional comparison of two entry-level mirrorless cameras that continue to command attention for different reasons: the Olympus PEN E-PL1 (2010) and the Panasonic Lumix DMC-GX850 (2017). Both occupy the Micro Four Thirds (MFT) ecosystem but mark distinct generational leaps in sensor technology, user interface design, and video capabilities, among other parameters.

This dissection serves photography enthusiasts and professionals desiring a precise, experience-backed understanding of how these cameras fare across photographic disciplines and real-world use cases. We prioritize raw feature breakdowns, operational nuances, and photography genre relevance, tempered with candid evaluations from extensive hands-on testing.

Physicality and Handling: Assessing Ergonomics and Form Factor

The physical dimension and control interface of a camera directly influence sustained usability and rapid operation under varied shooting conditions.

• Olympus E-PL1 measures 115 x 72 x 42 mm, weighing about 334 g (body only).
• Panasonic GX850 is noticeably smaller at 107 x 65 x 33 mm, tipping the scales at 269 g.

The 2017 Panasonic camera’s compactness prioritizes pocketability and discretion - beneficial for street and travel photographers who need lightweight setups for all-day carry. However, its minimalist grip offers less tactile stability compared to the slightly more substantial E-PL1, which weighs more and provides a modest grip bulge. Experienced users might find the E-PL1’s ergonomics more forgiving for telephoto or prolonged handheld shooting, though the GX850's size is less intrusive in crowded or rapid-fire settings.

Control layout also reflects divergent design philosophies. The Olympus features clearly marked dials and buttons conducive to quick mode changes, favored by photographers accustomed to manual exposure control. In contrast, Panasonic relies more on touchscreen-driven interaction, leading to smaller physical buttons and fewer tactile controls.

The E-PL1’s lack of touchscreen constrains some workflows but similarly minimizes accidental input, a subtle advantage in fast-paced shooting. The GX850’s touchscreen responsiveness and tilting articulating screen align closely with vlogging and selfie work, expanding compositional flexibility at self-shooting angles.

Sensor Technology and Image Quality: Resolution, Low-Light, and Dynamic Range

The heart of any photographic tool lies in its sensor and image processing capacity.

Both cameras employ a Four Thirds sensor with identical dimensions of 17.3 x 13 mm (approx. 225 mm² sensor area), thus sharing the fundamental crop factor of 2.1x. Despite the sensor size parity, the Panasonic GX850’s sensor resolution is 16 MP compared to 12 MP on the Olympus E-PL1. This 33% jump in pixel count translates to:

• Higher image resolution (4592 x 3448 px vs. 4032 x 3024 px) enabling crisper details and larger print outputs.
• Greater cropping freedom, beneficial for wildlife and sports photography.

Further image quality advantages emerge when examining DxO Mark scores:

The GX850 asserts a clear lead in dynamic range - a critical factor for landscape photographers managing high-contrast scenes - and low-light capability, which enhances noise performance at elevated ISOs for night or astro imaging.

Notably, the Olympus sensor includes an anti-aliasing filter, which can soften fine details but reduces moiré. Panasonic omits the filter, allowing more micro-detail capture at some risk of pattern artifacts, a tradeoff advanced users should consider.

Autofocus Systems: Speed, Precision, and Tracking

Autofocus (AF) sophistication defines usability across nearly all photography genres. Both cameras employ contrast-detection AF but diverge in implementation:

The Panasonic’s significantly higher number of focus points supports more granular subject acquisition and smoother focus tracking, key for dynamic subjects like wildlife and sports. The addition of focus bracketing and stacking functionality advances macro work considerably, enabling focus precision impossible on the E-PL1.

Touch-to-focus capability on the GX850 expedites subject locking in complex scenes and supports intuitive control - a substantial ergonomic gain over Olympus’ button-only AF interface lacking touch.

Build Quality, Weather Resistance, and Durability

Neither model features weather sealing or ruggedization, limiting outdoor professional usage in adverse conditions. The Olympus E-PL1’s older chassis uses a combination of metal and plastic parts, yielding reasonable durability but heavier weight. The Panasonic GX850’s all-plastic construction keeps weight down but may feel less robust in the hand.

No shockproof, crushproof, or freezeproof certifications exist for either; photographers requiring such resilience must look elsewhere in the MFT lineup.

LCD and Viewfinder Experience: Composing and Reviewing Shots

• Olympus E-PL1 has a 2.7-inch fixed LCD with 230k-dot resolution, employing HyperCrystal AR coating but no touchscreen capability.
• Panasonic GX850 offers a 3.0-inch tilting touchscreen LCD at a much higher 1040k-dot resolution, facilitating accurate composition in bright conditions and intuitive touch-based operation.

The absence of an EVF in both models constrains eye-level framing accuracy and stability. Photographers predisposed to viewfinder use will find such omission a critical limitation, especially in bright outdoor environments.

However, the GX850’s vari-angle screen, combined with touchscreen AF, partially compensates by enabling composing from difficult angles and rapid focusing - attributes well-suited to street, travel, and selfie photography.

Burst Shooting and Shutter Performance: Catching the Decisive Moment

• Olympus E-PL1 maxes out at 3 fps continuous shooting, with shutter speeds from 60 s to 1/2000 s.
• Panasonic GX850 manages 10 fps burst mode, with shutter speeds ranging between 60 s and an electronic shutter capable of 1/16000 s, including silent shooting.

For sports and wildlife photography, the GX850's superior frame rate offers obvious advantages, increasing the probability of capturing peak action. Its high maximum shutter speed also mitigates overexposure risks in bright conditions allowing wide apertures; the Olympus is severely handicapped in this regard.

The Olympus mechanical shutter top sync speed is 1/160 s, while the Panasonic's info on max flash sync is unspecified, a potential concern for studio off-camera flash timing.

Video Capabilities: From Basic to 4K

Video recording remains an increasingly critical feature set. Summarizing camera video specifications:

The Olympus E-PL1 supports only HD at 720p and uses an older Motion-JPEG codec, which results in larger file sizes and comparatively poorer video quality. Its lack of 1080p or higher video recording options places it well behind modern standards.

The Panasonic GX850 impresses with full 4K UHD capture at reasonable bitrates (up to 100 Mbps), improving video sharpness and color fidelity. However, it lacks in-body or electronic stabilization for video, requiring stabilization support from lenses or rigs.

4K Photo is a valuable addition for dynamic scenes, allowing still-frame extraction from 4K footage - a useful tool for wildlife and sports shooters needing numerous frames per second without sacrificing image quality.

Battery Endurance and Storage Flexibility

Battery life in mirrorless systems is often a highlighted user pain point.

• Olympus E-PL1 rated for approximately 290 shots per charge (CIPA standard).
• Panasonic GX850 rated for about 210 shots per charge.

Real-world shooting invariably yields lower frame counts due to previewing, AF operations, and video use; thus, the Olympus offers a slight advantage for longer days in the field without spare batteries.

Both utilize a single card slot:

• Olympus uses standard SD/SDHC cards.
• Panasonic supports microSD/microSDHC/microSDXC, a slightly less common form factor that requires compatible cards but offers compactness.

Connectivity and Wireless Features

Connectivity affects workflow integration, especially in professional or social settings.

• The Olympus E-PL1 lacks wireless features altogether.
• The Panasonic GX850 incorporates built-in Wi-Fi, enabling remote control, image transfer, and social media sharing workflows.

Though the GX850 lacks Bluetooth and NFC, its Wi-Fi facilitates tethered shooting and mobile device integration, essential for travel and event photographers prioritizing rapid sharing.

Lens Ecosystem and Accessory Compatibility

Both cameras leverage the Micro Four Thirds lens mount, affording access to a large lens catalog exceeding 100 offerings from Panasonic, Olympus, and third-party manufacturers.

Olympus and Panasonic lenses differ in optical stabilization approaches (Olympus favors in-body stabilization, Panasonic often lens-based), affecting lens selection strategies relevant to video shooters and handheld photographers.

The Olympus E-PL1’s in-body image stabilization (IBIS) supports all lenses, a distinct advantage for many users lacking optically stabilized glass. The GX850, conversely, does not feature sensor-shift stabilization, relying on stabilized lenses for shake reduction.

Both cameras lack built-in viewfinders but accept external EVF attachments in Olympus’ case, a possible upgrade path missed by Panasonic GX850 users.
