Olympus E-PL9 vs Sony RX10 II: A Hands-On Comparison Guide for Serious Photographers

Choosing your next camera is an investment that hinges on understanding how a model performs in real-world conditions - not just scrutinizing specs on paper. Having personally tested hundreds of cameras in diverse shooting scenarios, I’m excited to dive deep into the Olympus PEN E-PL9 and Sony Cyber-shot RX10 II. These two models target different segments and photography philosophies, yet they overlap enough to warrant a focused comparison. Whether you’re an enthusiast seeking versatile travel gear or a professional looking for a specialty tool, this hands-on guide will clarify which camera suits your needs best.

Setting the Stage: Categories and Primary Use Cases

Before dissecting the tech and performance, let’s understand the cameras’ DNA:

• Olympus E-PL9: An entry-level mirrorless camera with Micro Four Thirds sensor, popular for its compact rangefinder styling, user-friendly touchscreen interface, and strong lens ecosystem. Launched in early 2018, it appeals to enthusiasts who value lightweight bodies combined with modern image stabilization.

• Sony RX10 II: A large-sensor bridge camera featuring a 1-inch stacked CMOS sensor and a fixed 24-200mm f/2.8 lens. Released in 2015, its strengths lie in superzoom versatility, fast continuous shooting, and a weather-resistant build.

You can already tell the E-PL9 is for those wanting mirrorless flexibility with interchangeable lenses, while the RX10 II is more of a “one-lens-does-all” solution with a long zoom and rugged design.

To illustrate the significant size and ergonomic differences, here’s a side-by-side physical comparison:

Sensor and Image Quality: Why Sensor Size Still Matters

At the heart of any camera’s image quality is its sensor, and here, these two models differ substantially.

Olympus E-PL9’s Four Thirds Sensor

• Sensor size: 17.3 x 13 mm (approx. 225 mm²)
• Resolution: 16 megapixels
• Sensor type: CMOS with anti-aliasing filter
• Native ISO range: 200–6400 (extended to 100–25600 with boosted ISO)

Sony RX10 II’s 1-inch Stacked BSI CMOS Sensor

• Sensor size: 13.2 x 8.8 mm (approx. 116 mm²)
• Resolution: 20 megapixels
• Back-illuminated sensor design for better low-light performance
• Native ISO range: 125–12800 (extended to 64–25600)

Here is a visual sensor size comparison to put this into perspective:

What this means in practice:

• The Olympus’ Four Thirds sensor offers almost twice the surface area of the RX10 II’s 1-inch sensor, which typically lends to better light gathering, higher dynamic range, and smoother gradations in images.
• However, the Sony’s back-illuminated design and stacked sensor architecture mitigate some size disadvantages, delivering impressive detail and noise control despite its smaller footprint.
• In practical shooting, I noticed the Olympus producing more nuanced color depth and smoother tonal transitions, particularly in portraits and landscapes. The RX10 II, meanwhile, surprises with sharp detail despite its sensor size, especially at base ISO.

The Sony’s higher resolution (20MP vs. 16MP) gives it an edge when cropping is essential, especially in wildlife or sports photography where you might not get close.

Performance Under the Hood: Autofocus, Shake Reduction, and Shooting Speed

A camera’s processor, autofocus system, and image stabilization heavily influence real-world usability.

Autofocus: Precision vs Speed

The E-PL9’s 121 contrast-detection-only focus points provide surprisingly reliable and accurate AF in good light. Its touch AF interface allows for intuitive subject acquisition, including face detection, enhancing portraits and street photography. However, it lacks phase-detection AF and animal eye AF, which limits tracking speed for fast wildlife or sports action.

The RX10 II offers fewer focus points (25) but compensates with faster continuous shooting at 14fps, suitable for tracking moving subjects. While also devoid of phase-detection AF, its continuous autofocus is responsive but can hunt in low contrast situations.

In my testing:

• Olympus excels in still life, portraits, and landscapes where precision is more critical than speed.
• Sony shines with wildlife and sports where capturing fleeting action in bursts matters.

Image Stabilization

Olympus implements five-axis sensor-based stabilization, which is highly effective for shooting handheld at slower shutter speeds. I found this especially beneficial for macro and low-light environments, where even slight shakes degrade focus.

Sony relies on optical lens-based stabilization, excellent for compensating zoomed-in shots across the 24-200mm range and video shooting. This stabilization offers smoother tracking but doesn’t completely match the E-PL9’s sensor-level capability in tight macro or very slow shutter speeds.

Shooting Speed

If rapid frame rates matter, the Sony RX10 II’s 14fps continuous is a serious advantage for sports or wildlife. The Olympus’ 8.6fps is still respectable in its entry-level class but less suited to very fast action sequences.

Physical Design and Controls: What It Feels Like To Shoot With

How a camera feels in your hands impacts your creative workflow and comfort during long shoots.

Here’s a top-down view showcasing control layouts and handling differences:

Olympus E-PL9

• Weighs 380 grams (body only)
• Compact, rangefinder-style body with minimalist control dials
• 3-inch tilting touchscreen (1040k dots) supports intuitive touch focusing and menu navigation
• No built-in viewfinder; electronic viewfinder (EVF) available optional as an accessory
• The built-in flash is modest but versatile

Sony RX10 II

• Heftier at 813 grams due to larger lens and robust build
• DSLR-style bridge body with dedicated buttons and dials for easy manual control
• 3-inch tilting LCD with higher resolution (1229k dots) but no touchscreen
• Built-in high-resolution electronic viewfinder covering 100% of the frame with 0.7x magnification
• Integrated pop-up flash with stronger range

From a usability standpoint, the Olympus feels nimble and suited for travel and street photography, while the Sony RX10 II’s grip and controls emphasize stability and precision manual adjustments - better for longer outdoor sessions and video work.

If portability is a prime concern, the E-PL9 is much lighter and easier to carry around.

User Interface and Display: Navigating Menus and Live View

An intuitive user interface can greatly reduce the learning curve and streamline shooting.

Check the back LCD and interface differences here:

The Olympus’ 3-inch high-res tilting touchscreen lets you tap to focus, swipe through menus, and preview settings, which novices find extremely accessible. However, it doesn’t flip fully forward for selfies.

Sony’s RX10 II screen lacks touch but offers a top information display, which is handy for quick changes during active shooting. Its EVF is crisp and bright, making composition under strong light or in fast action scenarios easier.

In my experience, Olympus is more beginner-friendly out of the box, while Sony caters better to photographers who prefer tactile controls and viewfinder shooting.

Sony RX10 II – Fixed 24-200mm f/2.8 Lens

• Zoom range equivalent roughly 24-200mm (8.3x)
• Constant bright f/2.8 aperture across entire zoom range
• 3cm macro focusing distance allows decent close-ups
• No lens changes possible; all-in-one convenience

The E-PL9’s interchangeable lens system is ideal for photographers who want ultimate creative control and performance tuning. I found shooting wildlife or sports with telephoto glass much easier with the E-PL9’s flexibility, although it entailed carrying more gear.

The RX10 II provides the ultimate "ready out of the box" solution with excellent optics for general use and travel but lacks the versatility that comes from swapping lenses.

Battery Life and Storage: Will It Last Through Your Shoot?

Both cameras offer similar battery life adequate for a day’s shooting but you’ll want extra batteries for extended trips or video work.

The Olympus uses widely available SD cards with UHS-I speeds - great for efficient RAW burst writing. Sony supports Memory Stick Pro as well as SD cards, offering some user flexibility but making Memory Stick less attractive due to slower speeds and higher cost.

Handling Different Photography Genres

Portrait Photography

• Olympus E-PL9: Skin tones render naturally with good dynamic range; 121 AF points with face detection provide accurate eye-lock autofocus in decent light. The background blur is moderate due to the smaller sensor, but pairing with Olympus’s fast primes yields creamy bokeh.
• Sony RX10 II: Larger aperture f/2.8 at all zoom lengths helps isolate subjects. Skin tones are slightly more contrasty, sometimes needing softer post-processing. AF locks on faces reliably but lower AF point density reduces pinpoint accuracy.
