Olympus E-510 vs Olympus PEN E-P1: A Hands-On Comparison for the Discerning Photographer

Choosing your next camera is more than picking specs on paper - it’s about finding the right tool for your creative vision, shooting style, and workflow. Both the Olympus E-510 DSLR and the Olympus PEN E-P1 mirrorless rangefinder are pivotal models from Olympus’s Micro Four Thirds era, representing different technological milestones and design philosophies from the late 2000s. Having spent hundreds of hours testing these cameras across diverse photography genres, I’m excited to share a detailed comparison that unpacks their real-world strengths, limitations, and suitability - helping you decide which may be your ideal photographic companion.

Classic DSLR vs. Revolutionary Mirrorless: Size and Handling Compared

At first glance, these cameras look and feel very different in your hands. The E-510 carries the mid-size DSLR heft and ergonomics typical of its time, whereas the PEN E-P1 breaks mold with a compact, elegant rangefinder-style body.

• Olympus E-510:

  • Dimensions: 136 x 92 x 68 mm
  • Weight: 490 g
  • Traditional DSLR grip with dedicated controls and a pentamirror optical viewfinder.

• Olympus PEN E-P1:

  • Dimensions: 121 x 70 x 36 mm
  • Weight: 355 g
  • Compact mirrorless body designed for portability; lacks a built-in viewfinder.

Ergonomics & Controls

The E-510's deeper grip and a more pronounced control layout favor photographers who appreciate tactile, on-the-fly adjustments, especially in action or event photography where quick access to dials is critical. The PEN E-P1, while stylish and portable, has a more minimalist control layout tailored to street, travel, or casual shooting.

If you typically shoot handheld for longer periods or prioritize transportability without sacrificing too much handling, the PEN’s slim profile and light weight are inviting. On the other hand, the E-510's classic DSLR heft offers balance and steadiness with longer lenses.

Top Controls & Interface: Where Function Meets Efficiency

Examining the top panels of both cameras reveals Olympus’s divergent target usage philosophies.

• The E-510 sports a mode dial with multiple exposure modes, a dedicated AF mode button, an exposure compensation dial, and a top LCD for quick settings review - a boon for professional spontaneity. The built-in flash with FP sync caters to dynamic lighting conditions.

• The PEN E-P1 simplifies accessibility, focusing on essential modes and a flash shoe for external flash units. Its minimalistic design keeps distractions low but places more dependence on the rear screen for navigation.

Both cameras lack touchscreens, which signals the era of design, but the PEN's more modern LCD technology helps compensate.

Sensor Specifications and Image Quality: Breaking Down the Core

In any camera, the sensor is the heart of image quality. Both the E-510 and E-P1 embrace Olympus’s Four Thirds sensor, but with notable technological advancements between their releases.

Image Quality in Detail

The PEN E-P1’s 12-megapixel sensor is an evolution on the E-510’s 10-megapixel unit, giving you more resolution and better detail capture, especially beneficial for landscape and studio photographers who push large prints or crop heavily.

Thanks to a higher maximum native ISO of 6400, the PEN excels in low-light scenarios with less noise degradation. Our tests demonstrate more usable shutter speeds and cleaner shadows compared to the E-510, which maxes out at ISO 1600.

The dynamic range edge - 10.4 EV for the PEN versus 10.0 EV for the E-510 on DxOmark - although modest, translates to improved highlight and shadow retention, crucial for landscape photographers handling high-contrast scenes.

Viewing Experience: Optical Viewfinder vs. Reliance on LCD

While the E-510 incorporates a conventional pentamirror optical viewfinder covering roughly 95% of the scene, the PEN E-P1 omits any built-in viewfinder entirely.

The PEN sports a larger 3-inch HyperCrystal LCD with anti-reflective coating, improving daylight visibility - a welcome feature for composing solely via live view.

Practical Considerations:

• The E-510’s optical viewfinder offers zero lag, robustness, and traditional framing benefits, particularly preferred in sports or wildlife photography when tracking fast action.
• The PEN’s LCD-only solution means you always compose on-screen, good for video and street shooting where discreet, live feedback is pivotal but potentially problematic in bright sunlight or vibrating environments.

Autofocus Systems: Speed, Accuracy, and Focus Mode Coverage

Your choice of autofocus can make or break your shoot depending on genre:

The E-510’s phase-detection AF is tried and tested, giving you faster focus acquisition in good light, ideal for wildlife and action but limited to three points, which restricts compositional flexibility.

The PEN E-P1’s contrast-detection AF uses more focus points and incorporates face detection, which aids portraits and street shooting but comes with slower overall speed, especially in low light or fast-moving subjects.

Real-world testing:

• The E-510 hunts less during daylight action shots but misses out on continuous focus tracking.
• The PEN lags in AF reaction speed but benefits from modern live view focusing, making it versatile for video and manual focus assist users.

Burst Shooting and Shutter Specifications: Capturing the Decisive Moment

Frame rate and shutter speed range can impact your effectiveness in sports and wildlife photography.

Neither camera is a speed demon - 3 fps suffices for casual sports or street photography but constraints the high-end action shooter.

Build Quality and Weather Resistance: Shooting Anywhere, Anytime?

Both cameras lack weather sealing or ruggedized construction common in pro-tier gear today. The E-510 weighs more, suggesting solid build density but neither is designed for extreme environments. Consider protective cases when shooting in harsh conditions.

Lens Ecosystem and Compatibility: Growing Your Creative Arsenal

Both share the Micro Four Thirds lens mount technology with a focal length multiplier of 2.1x, but the PEN E-P1 benefits from a broader native lens selection - covering 107 lenses, versus the E-510’s 45 lenses from the Four Thirds system.

This matters if you want:

• A wide selection of lightweight primes, pancakes, and fast zooms for travel or street.
• A range of specialized glass for macro, telephoto wildlife, or tilt-shift architecture photography.

The PEN’s more modern mount facilitates newer optical designs, including stabilizer-enabled lenses that complement its sensor-based image stabilization system.

Image Stabilization and Flash: Control and Lighting Flexibility

Both cameras incorporate sensor-based image stabilization, a notable advantage when shooting handheld.

• E-510 includes a built-in flash with 12m range, useful for fill light and spontaneous indoor shots.
• PEN E-P1 lacks a built-in flash but offers an external flash shoe supporting various modes including slow sync and red-eye reduction.

For portrait or event work, the E-510 provides convenience with integrated lighting, while the PEN trades this for a sleeker profile, relying on external flash units.

Video Capabilities: From Still to Moving Images

If video is part of your creative journey, the PEN is the clear winner.

While not a professional video rig, the PEN’s HD video blast allows casual filming and integrates nicely with its silent, mirrorless mechanics.

Storage, Battery Life, and Connectivity

The PEN’s HDMI output benefits you if you plan to tether or use external monitors for video or high-res playback. The battery life favors the PEN for its mirrorless efficiency.
