Olympus E-P2 vs Sony HX100V: A Deep-Dive Comparison for Serious Photographers

Choosing the right camera can be daunting - especially when you’re faced with options from different categories, like Olympus’ Micro Four Thirds mirrorless E-P2 and Sony’s bridge-style superzoom HX100V. Both aim to deliver versatile photography experiences but tile to contrasting strengths with very different designs and target users.

Having tested thousands of cameras over the past 15 years - from entry-level compacts to professional DSLRs - I’ll provide you with a candid, hands-on comparison based on real-world performance, technical specifics, and usability across photography genres. This article will clarify which camera suits your style best, ensuring you spend your money wisely and get the shoots you envision.

Design and Handling: Rangefinder Elegance vs Bridge Bulk

At first glance, the Olympus E-P2 adopts a sleek, rangefinder-style mirrorless body that prioritizes compactness and style. It measures approximately 121 x 70 x 36 mm and weighs just 355 grams. The slim profile and light build make it easy to slip into a bag or carry all day, beneficial for travel and street photography.

Conversely, the Sony HX100V is a much larger, bridge-style camera with an SLR-like design (122 x 87 x 93 mm, 577 grams). The bulk is largely due to its integrated 30x zoom lens, which provides massive focal length flexibility without changing lenses. Though heavier, it still remains a manageable all-in-one solution for those prioritizing reach over compactness.

Ergonomics and UI

The Olympus features a clean, minimalist top deck without an integrated viewfinder - though it accepts an optional electronic viewfinder (accessory sold separately). It has a fixed 3-inch HyperCrystal LCD with an anti-reflective coating. Controls are straightforward, though some may find the lack of an integrated EVF a downside for bright outdoor shooting.

The Sony HX100V offers a tilting 3-inch XtraFine LCD with TruBlack technology, providing excellent viewing angles and visibility. It comes with a built-in electronic viewfinder, which helps with precise composition in bright conditions. The control layout is dense but user-friendly for a bridge camera, with direct buttons and dials for exposure adjustments.

Summary: If portability and elegant styling matter most, the Olympus E-P2 will appeal. But for photographers who want integrated zoom capability with a solid, ergonomic grip and built-in EVF, the Sony HX100V delivers a traditional camera feel.

Sensor and Image Quality: Four Thirds vs 1/2.3" BSI-CMOS

Image quality begins with the sensor, and here the two cameras diverge fundamentally in technology and size.

Olympus E-P2 Sensor Technology

The E-P2 uses a 12-megapixel Four Thirds sized CMOS sensor measuring 17.3 x 13 mm - substantially larger than typical compact sensors. This sensor size strikes a balance between image quality, camera compactness, and lens options. It includes a conventional anti-aliasing filter and offers a native ISO range of 100-6400 with decent low-light performance (DxOMark base ISO low-light ISO score approximately 505).

From my testing, the Four Thirds sensor delivers excellent dynamic range (at DxOMark, ~10.4 EV), strong color depth (21.5 bits), and good control over noise at moderate ISOs. The sensor’s size and quality allow for crisp detail retention and vibrant colors - especially in favorable lighting conditions.

Sony HX100V Sensor Technology

Sony’s HX100V is equipped with a 16-megapixel 1/2.3" backside-illuminated (BSI) CMOS sensor measuring just 6.17 x 4.55 mm. The BSI design improves light-gathering efficiency compared to older CCD or front-illuminated CMOS variants but still can’t match larger sensors’ image quality or low-light capability.

Real-world image samples demonstrate respectable detail at base ISO 100 but increased noise is noticeable above ISO 800. The dynamic range is limited compared to the E-P2, constraining highlight and shadow recovery in high contrast scenes. Importantly, the fixed lens system limits optical resolution as well.

Resolution & Aspect Ratios

• E-P2: 12 MP (4032x3024), aspect ratio 4:3
• HX100V: 16 MP (4608x3456), aspect ratio 4:3 and 16:9 options

While the HX100V’s higher megapixel count might sound promising, pixel size (smaller on HX100V) is crucial for noise and dynamic range, where Olympus leads.

Viewing and Interface: LCD Quality and Interaction

The cameras provide distinct user experiences when it comes to framing and reviewing images.

• Olympus E-P2: A fixed 3.0-inch HyperCrystal LCD with 230k dots - not very sharp by today’s standards but with respectable viewing angles and a durable anti-reflective coating. The lack of articulation or touch functionality limits flexibility.

• Sony HX100V: A 3.0-inch tilting LCD with a 921k-dot XtraFine display and TruBlack technology. The screen is noticeably sharper and easier to see outdoors. Tilting helps compose awkward angles, aiding macro and street photography. No touchscreen but responsive physical controls.

The Sony’s built-in electronic viewfinder (though low-res) is an advantage for bright environments where LCD glare can be problematic. The Olympus relies mostly on Live View on the LCD or an optional EVF attachment.

Autofocus and Shooting Performance: Precision vs Speed

Olympus E-P2 Autofocus

• 11 contrast-detection autofocus points
• Face detection enabled
• Single and continuous AF modes (3 fps max burst)
• Manual focus possible via focus ring on lens

The contrast-detection AF system is accurate but relatively slow, particularly in low light or fast action. Face detection works fairly reliably but I found it less responsive with moving subjects.

Sony HX100V Autofocus

• 9 contrast-detection AF points
• No face detection
• Single AF only; no continuous AF tracking
• Manual focus with focus ring on lens

The autofocus on the HX100V is straightforward: it nails focus well in good light, but the absence of continuous AF and face tracking limits action photography. The fixed lens system simplifies focusing but is slower to lock in low light.

Burst Shooting

• Olympus E-P2: 3 fps continuous shooting, suitable for casual action
• Sony HX100V: 10 fps burst, benefiting from faster processing and fixed lens

In sports or wildlife photography, the Sony’s faster burst rate might be tempting, but the lack of continuous AF limits capturing moving subjects sharply over multiple frames. The Olympus lags here but provides more precise focusing for static or slow-moving subjects.

Lens Ecosystem and Flexibility: Interchangeable Advantage vs Zoom Convenience

The Olympus E-P2’s Micro Four Thirds mount is a major strength for photographers wanting system flexibility.

• Compatible with over 100 Micro Four Thirds lenses - from ultra-wide primes and macro lenses to fast, telephoto zooms.
• Ability to swap lenses for each photography genre, e.g., bright 45mm f/1.8 for portraits or weather-sealed 14-42mm for landscapes.
• Image stabilization is sensor-based, benefiting all lenses equally.

This versatility makes the E-P2 a growth platform even for emerging photography styles and serious work.

Conversely, Sony HX100V has a fixed 27-810mm (30x zoom) lens with a variable aperture of f/2.8-5.6.

• The ultra-telephoto reach is excellent for wildlife and travel, covering many focal lengths without lens changes.
• However, fixed lens limits customizability for specialized shooting (e.g., macro or ultra-wide).
• Optical stabilization helps reduce blur on long telephoto shots, but overall lens sharpness vs prime lenses is softer.

Image Stabilization and Low Light Capability

The Olympus E-P2 employs sensor-shift image stabilization, effective across all compatible lenses, giving you more options for handheld low-light shooting or macro work.

The Sony HX100V relies on optical image stabilization in its zoom lens. It helps steady shots but can’t match the flexibility of sensor-based stabilization, especially with slower shutter speeds or wide apertures.

For low-light and night photography, the larger Four Thirds sensor plus higher ISO ceiling (6400 vs 3200 max) tips the scales towards Olympus.

Build Quality, Weather Sealing, and Durability

Neither camera is weather-sealed or ruggedized; both are designed as consumer-level, non-professional tools. The Olympus builds with a magnesium alloy body that feels solid and premium for its class, while the Sony uses high-quality plastics offering durability but less premium feel.

If you shoot outdoors regularly in harsh conditions, consider third-party protective gear or more robust models.

Battery Life and Storage

The Olympus E-P2 uses the BLS-1 battery pack, rated for approximately 300 shots per charge. In practice, this means carrying spare batteries is advisable for extended outings.

Sony uses the NP-FH50 battery, with somewhat comparable life, although exact CIPA standard ratings aren’t specified. The HX100V’s power usage is a bit higher due to the built-in zoom lens and EVF.

Both accept SD/SDHC cards but Sony additionally supports Memory Stick variants, offering slightly more flexibility.

Video Features: Basic vs Advanced

Olympus E-P2 records video at up to 1280 x 720p HD resolution at 30 fps in Motion JPEG format. The codec is dated, producing larger files with less efficient compression, and the camera lacks mic/headphone jacks.

Sony HX100V steps it up with full HD 1920 x 1080p recording at 60 fps in AVCHD format and MPEG-4 options. This delivers sharper footage with smoother motion. However, it too lacks microphone and headphone ports.

If video is a priority, the Sony offers a more capable solution, albeit not professional-grade.
