Olympus PEN E-PM1 vs Panasonic Lumix DMC-FH7: A Practical Comparison for Photography Enthusiasts

In the realm of entry-level cameras circa 2011, two distinctly different approaches aimed to attract new photographers and casual shooters. The Olympus PEN E-PM1 steps forward as a compact mirrorless system camera, while the Panasonic Lumix DMC-FH7 is a small-sensor compact with a fixed zoom lens - a classic pocketable shooter. After personally testing and assessing these cameras extensively, I want to take you through a detailed comparative exploration that spans sensor technology, handling, autofocus, image quality, video, and more.

Whether you’re a budding enthusiast stepping into mirrorless or a casual snapper considering a compact point-and-shoot, my goal is to offer clear-eyed insights based on hands-on experience and technical understanding. By grounding the discussion in real-world use, I hope to help you make an informed decision that suits your workflow and photographic interests.

First Glance: Size, Handling, and Ergonomics

One of the most immediate differences you notice holding these cameras is their form factor and control layout. I like to start here because handling directly impacts your shooting experience every day.

The Olympus E-PM1 commits to a rangefinder-style mirrorless design with a Micro Four Thirds lens mount, making it a more traditional camera body with physical controls and lens interchangeability. In contrast, the Panasonic FH7 is a slim, lightweight compact with an integrated zoom lens optimized for portability.

At roughly 110x64x34mm and 265g, the Olympus feels solid and more substantial in hand, striking a comfortable middle ground between portability and usability. Its grip and button placement invite control - important when shooting in varied conditions or needing quick adjustments. The Panasonic, at only 95x56x19mm and 126g, is ultra-light and pocket-friendly, but sacrifices tactile controls for a minimalistic interface.

Looking at the top plate, the E-PM1 offers dedicated dials and buttons allowing intuitive access to shutter speed, aperture, exposure compensation, and drive modes - features enthusiasts appreciate for creative flexibility. The FH7, however, relies mostly on menu-driven settings and touchscreen input, as evidenced by its lack of manual exposure modes or physical dial controls. For the photographer who likes “one shot and go,” this is fine; for anyone wanting artistic control, the FH7 feels restrictive.

Ergonomics verdict:

• Olympus E-PM1: Comfortable, traditional camera design that supports extended shooting sessions and manual control.
• Panasonic FH7: Ultra-compact and discreet, ideal for quick snapshots and travel but limited for creative manual operations.

Diving Into the Sensor: Image Quality and Technical Capability

Sensor size stands out as the most significant determinant of image quality between these two models. The Olympus E-PM1 sports a Four Thirds-sized CMOS sensor measuring 17.3x13mm with a 12MP resolution, whereas the Panasonic FH7 is equipped with a much smaller 1/2.3" CCD sensor at 6.08x4.56mm but with a higher megapixel count of 16MP.

From a technical standpoint, sensor size generally correlates strongly with dynamic range, noise performance, and depth of field control - cornerstones of image quality.

I conducted side-by-side testing in controlled studio environments and natural landscapes to evaluate color fidelity, dynamic range, and noise at various ISO settings. The Olympus sensor benefited from a TruePic VI processor and an anti-aliasing filter, delivering notably better color depth (21 vs. untested in the Panasonic), dynamic range (approximately 10.3 stops), and reasonable low-light performance (DxOMark low-light ISO of ~499). While the Panasonic's sensor impressively sports 16MP, the small pixel pitch and CCD technology limit its ability to gather light effectively, causing higher noise levels from ISO 800 upwards and distinctly compressed dynamic range.

For example, on a sunny afternoon landscape shoot, the Olympus retained more highlight detail and smoother gradients in sky and foliage, thanks to its sensor and native ISO range. The Panasonic often clipped highlights earlier and showed noticeable luminance noise - partially attributable to its non-CMOS sensor.

Image Resolution Insight:

• Olympus E-PM1: 4032x3024 max resolution, balanced between megapixels and pixel size for good print quality up to A3.
• Panasonic FH7: 4608x3456 max resolution, but the small sensor limits how much detail is usable, especially under challenging light.

The User Interface and Rear Display Experience

Back display usability often makes or breaks a camera when shooting in the field or reviewing images after a long day.

The Olympus E-PM1 offers a 3-inch fixed HyperCrystal LCD with Anti-Reflective coating and a reasonable resolution of 460k dots. The screen is crisp and bright, making manual focus confirmation and exposure adjustments easier. However, it lacks touchscreen functionality.

In contrast, the Panasonic FH7 has the same 3-inch size but a lower resolution of 230k dots, causing slight graininess and less sharp image previews. It does feature touchscreen capabilities, providing intuitive operation of menus and focus area selection, which can be helpful to casual shooters. However, the touchscreen is somewhat laggy and limited by firmware, so don’t expect smartphone-grade responsiveness.

In practice, reviewing images on the Olympus yielded more confidence in sharpness and framing, while the Panasonic’s interface was simple but sometimes felt sluggish.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus is a key differentiator, especially between a mirrorless interchangeable lens camera and a fixed-lens compact. The E-PM1 features a contrast-detect autofocus system with 35 focus points, face detection, continuous AF, tracking, and selectable AF areas - all impressive for its era and category. Panasonic’s FH7 offers only 11 focus points with contrast detection and face detection but lacks continuous AF modes or manual focus control.

In practical field testing, the E-PM1 focused faster and more reliably in both bright and low-light conditions. Its continuous AF allowed for better tracking of moving subjects, beneficial when attempting action or wildlife photography despite the modest burst rates (6 fps). The Panasonic FH7 was noticeably slower, with hunting common in low-contrast scenes; it shines as a casual point-and-shoot but lacks the speed or accuracy enthusiasts demand.

I tested continuous shooting rates as well - Olympus edges ahead at 6 frames per second against Panasonic's 4 fps burst, further emphasizing the mirrorless system’s advantage for moderately dynamic shooting situations.

Lens System and Flexibility

One of the most attractive attributes of the Olympus PEN E-PM1 is its compatibility with the Micro Four Thirds (MFT) lens ecosystem. At launch, over 100 lenses were available from Olympus, Panasonic, and third-party manufacturers - ranging from ultra-wide primes to super-telephoto zooms, macro lenses, and creative specialty glass.

This lens adaptability opens doors for portraiture, landscapes, wildlife, macro, and travel photography by allowing precise pairing of optics to the photographic genre.

The Panasonic FH7 only has a built-in 28-112mm equivalent zoom lens at an aperture range of f/3.1 to f/6.5. It is sharp and versatile for snapshots but lacks the aperture speed or focal length reach some specialists need. The 4x zoom is convenient but optically compromises in low light and lacks depth of field control for professional-style portraits.

Overall, Olympus’s lens mount flexibility is a decisive advantage for advanced users seeking system growth, while Panasonic appeals to those who prefer simplicity and no-lens-changing hassle.

Battery Life and Storage

The E-PM1 uses the BLS-5 battery pack with official ratings around 330 shots per charge. During my tests, actual usage performance hovered close to this figure, considering mixed manual and auto modes. The FH7’s smaller batteries give around 260 shots, noticeably less but reasonable for a compact.

Both cameras support SD/SDHC/SDXC cards, but the Olympus’s use of USB 2.0 and HDMI out provides better options for tethering or playback on external displays - areas where the Panasonic is more limited (no HDMI). Neither offers wireless connectivity or Bluetooth, reflecting their 2011-era design.

Build Quality and Weather Sealing

Neither camera is weather-sealed or ruggedized. However, the Olympus has a more robust feel with a sturdy magnesium alloy-like finish compared to the mostly plastic shell of the Panasonic. For photographers dabbling outdoors or in mixed weather, the Olympus offers a bit more confidence, but caution is still needed in challenging environments.

Video Capabilities

For those considering hybrid photography and videography use, camera video specs can’t be overlooked.

The Olympus PEN E-PM1 records 1080p Full HD video at 60fps using AVCHD or Motion JPEG codecs with no external microphone port - a drawback for serious videographers. Its sensor-based image stabilization helps with handheld shooting, but rolling shutter artifacts are moderate.

The Panasonic FH7 offers 720p HD video at 30fps (AV CHD unavailable here), a step down, reflecting the compact’s consumer orientation. Its optical image stabilization improves handheld shake reduction at video capture, but limited resolution and codec options restrict professional use.

Neither camera supports 4K or advanced video features like zebra patterns or focus peaking, which is understandable given their launch timeframe.
