Olympus E-PL1s vs. Panasonic GF1: A Real-World Showdown of Early Micro Four Thirds Mirrorless Cameras

In the fast-evolving world of mirrorless cameras, the Micro Four Thirds (MFT) system steadily carved a niche by combining compactness with serious photographic chops. Among the early trailblazers, two models stand out: the Olympus PEN E-PL1s and the Panasonic Lumix DMC-GF1. Both launched around the dawn of the 2010s, these entry-level mirrorless cameras have since become favorites for enthusiasts looking to balance portability, image quality, and versatility.

Having spent countless hours - and trust me, far too many cupfuls of coffee - testing these cameras side by side, I’m here to roll up my sleeves and break down how the E-PL1s stacks up against the GF1. From sensor tech to ergonomics, autofocus to video, and every photography discipline in between, this comparison aims to leave you confidently informed on which model might be your perfect match.

Buckle up - it’s going to be a detailed, experience-rich ride.

Size and Ergonomics: Handling and Comfort in Your Hands

Let’s start where you feel the camera first: the physical grip and tactile interface. Both cameras sport a classic rangefinder-style mirrorless silhouette, but subtle design choices influence user comfort and shooting style.

The Olympus E-PL1s measures 115 x 72 x 42 mm and tips the scales at 334g (body-only), whereas the Panasonic GF1 is slightly broader but thinner - 119 x 71 x 36 mm, weighing 385g. On paper, Olympus wins a few brownie points for lighter weight, but the Panasonic’s sleeker body offers a different feel in the hand.

What does this mean for you? If you have smaller hands or plan to shoot all day handheld, the E-PL1s’s slightly fattier but more grippable build might reduce fatigue. I found the grip more secure when shooting portraits or street photography for extended sessions with the E-PL1s.

Conversely, the GF1’s minimalist design pairs beautifully with pancake lenses, making it an attractive companion for travel or blending into street photography scenes. Its slimmer profile slips easily into a jacket pocket or small bag - very handy when you want to travel light without sacrificing camera control.

That said, neither camera features extensive weather sealing, so for photographers routinely shooting in challenging environments, cautious handling is advised.

Top Plate and Controls: Quick Access When It Counts

Once you’ve got the cameras in hand, how about control layout and button ergonomics? Efficient tactile navigation becomes critical when moments don’t wait.

The top plate reveals telling contrasts. Both models stick to an exposure-compensation dial, dedicated shutter buttons, and mode dials offering manual, aperture priority, shutter priority, and program modes.

I appreciate Olympus’s clean layout, which includes a built-in flash with a pop-up mechanism easily accessed by flicking a switch. The E-PL1s incorporates a modest array of buttons but no illuminated controls - a minor complaint in low-light shooting.

Panasonic’s GF1, meanwhile, integrates an external flash hot shoe but no built-in flash - something that might influence your decision if on-the-fly fill lighting is critical. The mode dial sits comfortably for thumb rotation with reassuring clicks, and I liked the more pronounced shutter button texture for decisive feedback.

Neither camera has focus or dial wheels with customization flexibility, but both include intuitive menus accessible mid-shoot. In practice, I found the Olympus’s exposure compensation dial slightly easier to reach without shifting my grip.

Sensor and Image Quality: Heart of the Matter

At the core lies the sensor - the kitchen where images are cooked. Both cameras use a 12MP Four Thirds CMOS sensor, sized 17.3 x 13mm, with a crop factor around 2.1×. But let’s peel back layers with technical scrutiny and imaging results.

The E-PL1s’s sensor benefits from Olympus’s TruePic V image processor, while Panasonic’s GF1 runs on the Venus Engine HD processor. Both processors support contrast-detection autofocus and provide solid JPEG rendering performance.

In laboratory-controlled tests, the GF1 slightly edges out with a respectable DxOMark overall score of 54, showing a color depth of 21.2 bits and a dynamic range of approximately 10.3 EV. Olympus lacks formal DxOMark testing, but based on pixel-level image analysis and real-world evaluations, the E-PL1s produces competitive image quality with punchy colors and commendable noise-handling to ISO 800.

However, Panasonic’s sensor and processor combo demonstrate smoother tonal gradation and a tad better low-light performance, with the maximum native ISO at 3200 (vs. Olympus’s 6400 ceiling).

Do these differences translate to visible impact? Only if you pixel-peep large prints or shoot extensively in dim conditions. For everyday enthusiasts aiming for social sharing or moderate-sized prints, both sensors deliver excellent image fidelity, capturing rich skin tones and pleasantly detailed landscapes.

Viewing and Composition: LCD Screens and Viewfinders

Composing your image is about seeing clearly and responding swiftly. Neither camera offers a built-in electronic viewfinder - a notable omission given today’s standards - but each approaches live view in its unique way.

The E-PL1s sports a fixed 2.7-inch LCD with a modest resolution of 230k dots, featuring Olympus’s HyperCrystal AR Coating designed to reduce glare. In practice, this screen fares well outdoors on overcast days but struggles under direct sunlight - expect some squinting or shading your hands.

Panasonic’s GF1 features a larger and sharper 3-inch TFT LCD with 460k dots, and a wide viewing angle. This translates to crisper image preview and more accurate focus checking, especially useful when zooming in on photos or using manual focus.

Neither has touchscreen functionality, which was still a rarity among cameras of that era, and unfortunately, neither supports attachable EVFs natively, which some competitors did offer.

In my experience, the Panasonic’s screen makes framing and reviewing images easier for extended shoots, particularly outdoors. Olympus’s display, while serviceable, feels a tad dated and less cooperative in challenging light.

Autofocus Performance: Hunting or Pinpoint?

Nothing kills photo mojo like a slow or wandering autofocus system. Both cameras deploy contrast-detection AF with 11 points for Olympus and 23 points for Panasonic.

The GF1’s denser AF point array gives it a slight advantage when tracking moving subjects or composing in awkward framing. The Olympus E-PL1s, despite fewer points, integrates face detection, enhancing portrait shooting accuracy.

During my field tests, the Olympus exhibited reliable AF in still and portrait scenarios, locking eyes and faces swiftly, albeit occasionally slower in low contrast or dim light. The Panasonic’s AF felt more responsive and consistent under varying conditions, ideal for spontaneous street or wildlife captures - assuming your lens supports fast focusing motors.

Continuous AF modes exist on both, but neither offers hybrid phase-detection systems common in later models - meaning hunting in tricky light is par for the course.

Screen Sizes and Resolution: A Peek From Behind

Both cameras use fixed rear screens, but their size and resolution differ.

Olympus E-PL1s comes with a 2.7-inch display at 230k dots, and Panasonic GF1 offers a bigger 3-inch screen at 460k dots. The GF1's larger, higher resolution screen provides finer detail and a better experience when reviewing shots or navigating menus. The E-PL1s uses HyperCrystal LCD technology with anti-reflective coating which helps somewhat with visibility outdoors.

The trade-off is the GF1 lacks an articulating screen, which neither camera offers, limiting flexibility for overhead or low-angle shooting.

Burst and Shutter Speeds: Capturing the Action

Burst shooting and shutter speeds can make or break capturing fast moments.

Both cameras share continuous shooting at 3 frames per second - adequate for casual sports and wildlife shots but modest compared to modern machines.

Olympus's shutter speed tops out at 1/2000s, while Panasonic pushes to 1/4000s. This matters mostly when shooting in bright light with fast lenses wide open or when aiming to freeze high-speed subjects with more precision.

Neither camera features silent or electronic shutter modes, so mechanical shutter sound is always present.

Image Stabilization: Steadying the Shot

Here’s where we see one key difference: the Olympus E-PL1s has in-body image stabilization (IBIS), which physically shakes the sensor to counteract hand movements. This is a fairly rare and valuable feature in the entry-level mirrorless world of its time.

The Panasonic GF1 lacks IBIS, relying solely on lens stabilization if your chosen lens provides it (many Panasonic lenses do, but Olympus's approach means any lens benefits).

From practical experience, IBIS on the E-PL1s can buy you an extra stop or two of handheld shooting freedom - great for low light or macro photography. The GF1 feels less forgiving in that regard.

Lens Ecosystem: The Power of Micro Four Thirds

Lucky for both models, they share the same Micro Four Thirds lens mount and the vast ecosystem that supports it, numbering over 100 native lenses from Olympus, Panasonic, and third-party makers.

Whether you're hunting for fast primes, versatile zooms, or macro optics, both bodies give you access to a rich selection.

Bear in mind, Panasonic lenses often focus faster on the GF1, but Olympus's IBIS makes up for some ground when using legacy MFT glass.

Built Quality and Weather Resistance: Ready For the Elements?

Neither camera is weather-sealed or ruggedized to withstand dust, moisture, or shocks. Both are designed with light use and moderate care in mind.

The Olympus E-PL1s feels a bit plasticky compared to Panasonic GF1's more solid metal chassis, which imparts a premium touch but adds some weight.

If you often shoot outdoors in unpredictable conditions, plan accordingly with protective accessories or opt for newer models with weather sealing.

Battery Life and Storage: How Long Can You Shoot?

The Panasonic GF1 boasts a longer battery life rating - around 380 shots per charge compared to Olympus's 290.

This difference, while not dramatic, translates into longer shoots without swapping batteries - a boon for travel photographers or anyone out and about without easy recharging options.

Both cameras use SD/SDHC memory cards, with the GF1 also supporting MMC cards - nothing groundbreaking, but keep in mind card speed for video and burst shooting.

Connectivity and Extras: What’s In and Out?

Neither camera offers built-in wireless connectivity such as Wi-Fi, Bluetooth, or NFC - no surprise given the period.

Both provide USB 2.0 ports and mini HDMI outputs, facilitating image transfers and direct playback on TVs - useful for reviewing images with friends or clients.

Microphone or headphone jacks for videographers? Nope, both cameras skip these.

Video Capabilities: Handy But Not Hollywood

In early mirrorless days, video was often an afterthought, and these cameras reflect that.

Both offer 720p HD video at 30fps, but Panasonic’s GF1 records in AVCHD Lite, providing better compression and quality than Olympus’s Motion JPEG format.

That said, neither supports full HD 1080p or 4K, and lack of microphone inputs limits serious movie-making potential.

For casual video clips, either will do, but don’t expect cinematic output or advanced video features.

Real-World Shooting Across Genres: Where Each Camera Shines

Let’s talk about how these cameras perform across various photography types, informed by personal shooting sessions.

Portrait Photography

Olympus’s face detection and IBIS make it a solid choice for portraits, delivering pleasant skin tones and smooth bokeh when paired with fast primes. The sensor's 12MP resolution is sufficient for typical print sizes.

Panasonic's more responsive AF with 23 focus points allows for capturing more spontaneous expressions - perfect for lifestyle or street portraiture. However, lack of IBIS might induce more blur if shooting at slow shutter speeds.

Landscape Photography

Both cameras provide similar resolution and sensor sizes, but Panasonic’s better color depth and dynamic range gleaned through DxOMark testing lend it an edge for landscape shooters who value detail and tonality.

Olympus's IBIS is less relevant here, given the common use of tripods. However, the larger LCD of the GF1 excels when evaluating framing in nature’s changing light.

Wildlife and Sports Photography

Neither is a powerhouse in speed, given 3 fps burst rate and contrast-detection focus. Panasonic’s wider AF coverage and faster shutter ceiling aids faster capture of fleeting moments, making it marginally the preferred option.

Olympus struggles a bit with sluggish tracking but can be adequate for cautious wildlife or casual sports shooting.
