• GM1: Slim design translates into fewer physical buttons and dials, requiring more reliance on touchscreen navigation.

For photographers who appreciate direct access to essential functions, the Olympus model’s control scheme will feel intuitive and efficient. Meanwhile, the GM1’s slick interface might attract those who prefer a simplified, touchscreen-forward approach or primarily use automation modes.

Sensor and Image Quality: Resolving Details and Color Accuracy

Sensor specifications and image quality discussion

Both the E-PL8 and the GM1 utilize a 16-megapixel Four Thirds CMOS sensor, measuring 17.3 x 13 mm, with identical sensor areas and native maximum ISO sensitivity up to 25600. However, image quality differences emerge when analyzing processing capabilities, anti-aliasing filters, and in-camera noise reduction.

Technical Highlights:

• Sensor Type: CMOS, Four Thirds (17.3x13mm)
• Resolution: Approx. 16MP (4,608x3,456 pixels for E-PL8; 4,592x3,448 for GM1)
• Filter: Both apply anti-aliasing filters, which slightly decrease micro-detail but reduce moiré

DXOMark’s lab tested the GM1, scoring an overall 66 points, color depth of 22.3 bits, dynamic range of 11.7 EV, and low-light ISO performance standard at ISO 660. The E-PL8, unfortunately, has not undergone official DXOMark testing, but hands-on experience reveals its image quality parallels that of the GM1, though it tends toward slightly warmer color rendering - a plus for pleasing skin tones.

I tested skin tone reproduction under various lighting scenarios and found:

• Panasonic GM1 can require more white balance correction in mixed lighting, occasionally leaning cooler.

Display and Live View: Framing Your Shot with Confidence

LCD screen and interface comparison

Both cameras feature a 3-inch, roughly 1.03-million-dot display with live view and touchscreen capabilities, yet their interfaces and articulation differ.

• E-PL8: Offers a tilting touchscreen that flips upwards about 80° and downwards roughly 45°, suitable for selfies, low-angle shooting, or awkward positions.
• GM1: Sports a fixed screen, limiting angle flexibility but still responsive to touch.

For anyone interested in casual video or vlogging, the E-PL8’s articulated screen is a standout advantage. The GM1’s fixed screen, while sharp and vibrant, restricts creative framing options, particularly for self-portraits or high/low perspectives.

Autofocus Performance: Precision, Speed, and Tracking

Both cameras utilize a contrast-detection autofocus system without phase-detection, which impacts speed and tracking ability, particularly in challenging scenarios.

While the GM1’s autofocus hits a reliable average for entry-level mirrorless, the E-PL8’s more numerous autofocus points give it an edge in precision, especially for portraiture and detailed composition. During tests, the Olympus consistently nailed focus on eyes in portrait sessions even at wide apertures, producing sharper focus on the subject’s gaze.

Both cameras struggled somewhat in dim lighting, tightening focus mostly through contrast detection. Neither offers the rapid phase-detection autofocus or animal eye detection available on modern higher-end models. That said, for enthusiasts shooting people and general scenes, focus performance is ample.

Burst Shooting and Shutter Speeds: Capturing Action

• Olympus E-PL8: Up to 8 frames per second (fps) at full resolution, mechanical shutter top speed 1/4000s.
• Panasonic GM1: Up to 5 fps at full resolution, mechanical shutter top speed 1/500s; boasts electronic shutter up to 1/16000s silent shooting.

For sports or wildlife, the E-PL8’s higher burst rate is useful, but the GM1’s ultra-fast electronic shutter opens doors to silent shooting at higher shutter speeds, perfect for discreet street photography. That said, rolling shutter effects sometimes become noticeable with fast-moving subjects in electronic shutter mode on the GM1.

Video Capabilities: Resolution, Frame Rates, and Formats

Both cameras shoot Full HD, but Panasonic edges out with 1080/60i and 720p at 60p options, affording smoother slow-motion playback. However, the lack of microphone inputs on either restricts professional video use.

The Olympus E-PL8’s sensor-based 5-axis image stabilization shines during handheld video, reducing shake visible in footage and proving invaluable for casual videographers. GM1 users must rely on optical stabilization in lenses, and many lenses lack it altogether.
