Olympus E-P2 vs Sony QX30: An Expert's Take on Two Unconventional Cameras

In the ever-evolving panorama of photography gear, some cameras don’t fit neatly into typical categories. Today, I’m diving deep into two unique, atypical models that showcase very different philosophies but target overlapping enthusiast markets: the Olympus PEN E-P2 - a pioneering entry-level mirrorless from 2010 - and the Sony Cyber-shot DSC-QX30 - a lens-style camera from 2014 designed for smartphone integration.

Though far apart in design and intent, both offer compelling propositions. Having put both through my hands-on testing workflow - assessing sensor technology, autofocus, shooting ergonomics, and real-world performance across a spectrum of photography genres - I’ll unpack their strengths, weaknesses, and practical suitability for photographers today.

Let’s get to know these two contenders.

Seen Through the Lens: How Big Are These Cameras, Really?

First impressions often hinge on handling and ergonomics. The Olympus E-P2 is a classic rangefinder-styled mirrorless with an interchangeable lens system, while the Sony QX30 is a compact lens-style camera designed to work tethered to a smartphone.

At 121 x 70 x 36 mm and 355g, the E-P2 is surprisingly compact for a mirrorless with a Micro Four Thirds sensor inside, giving it an almost pocketable feel without sacrificing control. Its retro styling echoes classic rangefinders, and its body provides a solid grip even with a modestly sized lens.

Contrast that with the Sony QX30’s minuscule 68 x 65 x 58 mm footprint and lightweight 193g weight. This almost-lens looks like a mechanical appendage rather than a traditional camera, no viewfinder, no screen, no independent controls - relying fully on a smartphone for viewfinding and control.

This difference underlines a key user experience divide: the E-P2 is a self-contained camera while the QX30 is more like a photographic lens with a sensor plus built-in zoom, designed for mobile convenience but dependent on external displays.

Top-Down Control & Intuitive Use

How you interact with your camera can make or break your photographic experience, especially when you want to shoot swiftly and confidently.

The Olympus E-P2 offers a traditional control layout, albeit minimalist by modern standards. Dedicated dials for shutter speed, aperture, and exposure compensation provide tactile feedback. Buttons are clearly labeled and well spaced. The TruePic V processor powers a reasonably responsive UI. However, the lack of an integrated viewfinder can occasionally slow framing, though an optional EVF was available separately.

The Sony QX30, by contrast, strips down physical controls to nearly zero. All interactions are through touch on your paired smartphone, leveraging the Bionz X processor within the lens-style unit. There's a shutter button on the body, but aperture, ISO, and other exposure settings are entirely app-dependent. This approach makes the QX30 exceptionally portable and lightweight but sacrifices immediacy and tactile control.

For photographers used to direct manual control, the Olympus shines. For casual shooters prioritizing minimal gear and smartphone integration, Sony’s approach has merit but requires some getting used to.

Sensor Technology & Image Quality: Size Matters

A critical factor from beginners to pros alike - sensor size, technology, and resolution massively influence ultimate image quality.

• Olympus E-P2: Four Thirds CMOS sensor, 17.3 x 13 mm area, 12MP resolution
• Sony QX30: 1/2.3” BSI-CMOS sensor, 6.17 x 4.55 mm, 20MP resolution

On paper, the QX30’s 20 megapixels trump the E-P2’s 12 million, but this is largely due to pixel density rather than a physically larger sensor. The E-P2’s Four Thirds sensor area is over 8 times larger, which generally translates to better dynamic range, lower noise, better low-light capability, and smoother gradients.

From my side-by-side tests shooting RAW files under varied lighting, the E-P2 consistently delivers punchier color fidelity, a wider dynamic range (approx. 10.4 EV vs. unknown for QX30 but limited due to sensor constraints), and much cleaner shadows at ISO 3200 and above. The QX30’s tiny sensor, while capable of detailed daylight shots, struggles with noise and smudging in subdued lighting.

It’s a compelling reminder that megapixels aren’t everything; sensor size and architecture reign supreme for image quality. The Olympus also supports RAW capture, critical for post-processing flexibility, while the QX30 does not.

The Viewfinder and Screen Experience

Neither camera sports an integrated viewfinder, opting instead for other viewing approaches.

The E-P2’s 3-inch fixed HyperCrystal LCD (230k dots) is serviceable, with anti-reflective coating but limited resolution by today’s standards. It offers basic live view with manual focusing aids - an acceptable compromise for its era but understandably rudimentary now.

The Sony QX30, lacking any built-in screen, depends entirely on your smartphone’s display. This means potentially high-res, touch-enabled controls with zoomable live view, but introduces lag and connectivity challenges depending on your phone and environment. Its touchscreen control interface via an app is a different user experience - sometimes clunky, sometimes surprisingly versatile.

For pure tactile shooting and quick framing, the E-P2 edges out due to dedicated hardware, though the QX30’s smartphone dependency can be liberating for social media-centric shooting.

Autofocus and Speed: Tracking the Action

Autofocus performance and burst shooting define usability in action, sports, wildlife, and candid genres.

• Olympus E-P2: Contrast-detection AF with 11 points, face detection, single/continuous AF modes, 3 fps burst
• Sony QX30: Contrast AF, face detection via app, single AF only, 10 fps burst

Although the QX30 can shoot continuously at a higher 10fps, its single AF mode limits dynamic subject tracking capabilities. The lens-style design’s autofocus is contrast-based and somewhat slow lens-to-lens, especially in low light.

The E-P2’s AF system is rudimentary compared to modern hybrids but supports continuous AF tracking better, and with dedicated lenses, it can lock focus with good reliability on static and moderately moving subjects.

In my field tests photographing moving street subjects and pets, the E-P2’s AF is more dependable and predictable, albeit not lightning-quick by today’s standards. The QX30’s faster burst is nullified somewhat by its slower focusing and touchscreen triggering delays.

For dedicated wildlife and sports action, neither camera is ideal but the Olympus fares better for intentional focus control.

Portrait & Bokeh Performance: Skin Tones and Eye Detection

Portrait photographers often prize accurate skin tone rendition and creamy, natural bokeh to isolate subjects beautifully.

The Olympus E-P2, with its larger Four Thirds sensor and access to a mature Micro Four Thirds lens ecosystem including primes with wide apertures (f/1.8 - f/2.8), can deliver flattering portraits with smooth background fall-off. Its face detection AF aids subject lock, though no specialized eye detection autofocusing was available at launch.

The Sony QX30’s fixed 24-720mm equivalent zoom has a small maximum aperture f/3.5-6.3, limiting bokeh capabilities substantially. Combined with the tiny sensor, achieving creamy separation is difficult except at extremely close distances. Relying on the smartphone app means manual focus tweaks can feel difficult during portrait sessions.

My experience favors the Olympus for portraits, producing warmer, more natural skin tones and background blur suitable for personal and client work.

Landscape and Travel: Dynamic Range, Resolution, and Portability

Landscape photography demands dynamic range, resolution to capture detail, and weather resistance for outdoor shooting.

Regarding dynamic range, the Olympus’s Four Thirds sensor provides a clear advantage, capturing a wider tonal spectrum which I verified shooting sunrises and mixed-lighting scenes. Its 12MP output remains respectable for large prints.

The Sony, despite higher megapixels, gives flatter HDR results with shadow clipping common in contrasty landscapes. Its sensor size and sensor noise limit image quality in these scenarios.

From a portability perspective, the Sony QX30’s small size is a dream for travel when paired with a smartphone - it folds into a small bag pocket with ease and covers an astonishing 30x zoom range. The Olympus, while compact, requires lenses added, adding bulk. However, its sturdier build and more reliable controls balance this out as a travel companion.

One downside - neither camera has weather sealing, so cautious outdoor use in adverse conditions is wise.

Macro and Close-up Capabilities

For macro shooting, focusing precision and stabilization are key. The Olympus PEN E-P2 benefits from changeable lenses, offering dedicated macro optics with close focusing distances (some as close as 0.15m) and image stabilization from the sensor. This combo facilitates sharper close-ups handheld.

The Sony QX30 lacks dedicated macro modes and depends solely on its optical zoom and contrast detection AF, which can hunt in tight macro focus zones.

In testing flower and insect subjects, the E-P2 outperformed with crisper detail and easier manual focus control.

Low Light and Nightscape Imaging

Evaluating ISO performance and noise management is crucial for evening, concert, and astrophotography.

The Olympus has a native ISO range 100-6400 and achieves useable results up to 3200 ISO with moderate noise, thanks to sensor size and processing. Its sensor-based image stabilization further aids slower shutter speeds.

The Sony’s small sensor limits native sensitivity to ISO 3200 at best and images quickly degrade in dim conditions.

Neither camera is designed for deep astrophotography or advanced night work, but Olympus’s larger sensor and stabilization offer greater creative flexibility in low light.

Video Capabilities: Resolution and Usability

Though primarily still-oriented, both cameras provide some video recording.

• Olympus E-P2: 720p HD at 30 fps, Motion JPEG codec
• Sony QX30: Full HD 1080p up to 60 fps, MPEG-4 codec

Videographically, the QX30 offers higher resolution and smoother frame rates, suitable for casual video. Yet, it lacks microphone input or stabilization modes for video.

The E-P2’s video is basic, limited resolution, and suffers from compression artifacts but provides manual exposure options.

For hybrid shooters prioritizing video, neither offers modern features like 4K, log profiles, or advanced codecs. The QX30’s smartphone tethering does enable some app-based controls and monitoring during recording.

Connectivity and Storage: Wireless Options

Connectivity strongly influences workflow today.

• Olympus E-P2: No wireless, USB 2.0, HDMI output, SD/SDHC card slot
• Sony QX30: Built-in Wi-Fi, NFC pairing with smartphones, USB 2.0, microSD card slot

The QX30’s wireless integration is its standout feature - allowing instant sharing via phone apps, remote shooting, and live view. This matches the design ethos of a smartphone accessory.

The E-P2, though lacking wireless, offers HDMI output for tethered shooting and a mature SD card ecosystem.

For on-the-go sharing and social media, the QX30’s wireless is a boost, but for serious offline work, Olympus’s traditional storage provides reliability.

Build Quality and Weather Sealing

Neither camera offers weather or environmental sealing. The E-P2’s metal chassis feels solid in the hand, and its classical design inspires confidence despite its age. The Sony QX30’s plastic shell feels more delicate; while compact, it requires careful handling especially when detached from a phone.

Battery Life and Storage

The Olympus E-P2 provides about 300 shots per charge (rating based on CIPA standards), typical of early mirrorless designs. The Sony QX30’s smaller battery supports approx. 200 shots per charge due to its wireless connectivity demands.

Storage-wise, the E-P2 supports standard SD cards, while the QX30 relies on microSD or Sony Memory Stick Micro, which might challenge sourcing for some users.
