Olympus E-PL6 vs Sony Cyber-shot DSC-TX9: A Thorough Comparative Analysis for the Discerning Photographer

When you start comparing a mirrorless camera like the Olympus PEN E-PL6 with an ultracompact point-and-shoot such as the Sony Cyber-shot DSC-TX9, it quickly reveals more than just differences in sensor size or lens interchangeability. These devices address fundamentally different photographic mindsets and use cases. Having spent over 15 years shooting everything from weddings to wildlife, and testing countless cameras in the lab and field, I’ve developed a toolkit to analyze these cameras on the merits that matter most to photographers.

In this article, we’ll dissect the Olympus E-PL6 and the Sony TX9 across all major photography disciplines, their technical nuances, and real-world usability. My goal is to empower you to make an informed choice based on your actual needs - not just specs sheets or marketing hype. So pack a mental bag and let’s dive deep into what these cameras can really offer.

Getting a Grip: Size, Ergonomics, and Handling

First impressions count, and that starts with how a camera feels in your hands during extended use. The Olympus E-PL6 embraces the classic rangefinder-style mirrorless form with a Micro Four Thirds system, measuring a solid 111 x 64 x 38mm and tipping the scales at 325 grams. In contrast, the Sony TX9 shrinks everything down to an ultracompact marvel, measuring 98 x 60 x 18mm and weighing only 149 grams.

Handling-wise, the E-PL6’s larger dimensions allow for a better grip and more tactile controls, which translates to less fatigue during prolonged sessions - especially if you pair it with a decent prime lens. Meanwhile, the TX9’s wafer-thin body slides easily into pockets or purses, making it a perfect “always-with-you” companion, but one that sacrifices some operability for portability.

The Olympus benefits from dedicated exposure compensation, shutter priority, aperture priority, and manual exposure modes - features absent from the TX9. The Sony’s control layout is streamlined but limited. For users comfortable with manual settings and prioritizing creative control, the E-PL6’s handling clearly wins out. Street shooters or casual travelers who want a grab-and-go option might prefer the nimble TX9.

From a UI standpoint, both offer tilting or fixed touchscreens, respectively. But the E-PL6’s 3-inch tilting display (460k dots resolution) provides more flexible framing options and usability in unconventional angles, while the TX9’s 3.5-inch fixed screen has higher resolution (922k dots), delivering crisper previews despite its static orientation. I’ll examine the screens more closely later.

Design Smarts: Top Controls and Interface

The user interface affects how quickly you can work, especially when fast reaction times are essential. The Olympus E-PL6 uses a classic top-plate layout with dedicated dials for ISO, exposure compensation, and drive mode. It’s a tactile, muscle-memory-friendly design reminiscent of traditional cameras, made for users who want direct access without digging through menus.

The Sony TX9 drops most of these controls for a minimalistic approach. You operate primarily via an extended touchscreen and a few physical buttons on top and back. While this simplifies operation for casual shooters, it may slow down experienced photographers in dynamic shooting scenarios.

In our lab testing, switching shooting modes on the Olympus was intuitively fast. The Sony’s workflow sometimes felt stilted due to the lack of physical dials and reliance on menus and touchscreen control, which can be frustrating when wearing gloves or outdoors in bright daylight.

For professional or enthusiast users who want to maintain creative momentum, the Olympus E-PL6 is clearly the more ergonomic and thoughtfully designed tool. The TX9 trades usability for compactness.

Heart of the Matter: Sensor Size and Image Quality

The sensor is the beating heart of any camera. And here the differences are stark. The Olympus E-PL6 features a 16-megapixel Four Thirds CMOS sensor measuring 17.3x13mm, yielding an imaging surface of nearly 225 mm². This is a significantly larger canvas than the Sony TX9’s 12-megapixel backside-illuminated CMOS sensor measuring only 6.17x4.55 mm (about 28 mm²).

The practical consequences of this size gap show up in image quality and performance:

• Dynamic Range: The larger four-thirds sensor exhibits superior dynamic range, allowing the E-PL6 to better preserve highlight and shadow details, which is critical in landscape and high-contrast scenes.
• Noise Performance: The Olympus handles high ISO values (up to ISO 25600 native range) with less noise and better tonal gradations compared to the Sony capped at ISO 3200.
• Color Depth and Detail: The E-PL6’s sensor and TruePic VI processor deliver more nuanced color reproduction and finer detail, especially in raw files.

While the Sony TX9 offers a respectable 12 MP output fine for casual snapshots and prints up to 8x10 inches, its small sensor struggles in low light or against bright skies, yielding noisier, less detailed images.

For photographers prioritizing image quality with cropping flexibility, printing large, or requiring strong low-light performance, the Olympus sensor is the clear winner from both my lab measurements and field tests.

Viewing the World: Viewfinder and Screen Technology

Neither camera includes a built-in electronic viewfinder, though the Olympus offers an optional external unit. Both rely heavily on their rear LCD screens for composing images. Here they approach their respective ends of the design spectrum.

The Olympus E-PL6’s 3-inch tilting touchscreen with 460k pixels is versatile. It swings upward and downward to aid shooting at high or low angles - this adds creative freedom but comes with slightly lower resolution, so fine detail preview is softer. Importantly, touch functionality extends to focus selection and navigating menus.

The Sony TX9 sports a fixed 3.5-inch touchscreen with 922k pixels - nearly double the pixel count - making it one of the best-resolution screens of its generation in an ultracompact. Touch responsiveness is solid, but the lack of tilting limits compositional versatility.

In outdoor bright light, I found the Olympus screen visibly less legible due to lower brightness, while the TX9's screen handled glare better. However, for angled or overhead shots, the Olympus screen was much more practical.

If you habitually shoot in tricky lighting or use live view as your primary framing method, the Sony’s high-resolution fixed screen impresses. Power users who venture into various shooting angles and appreciate touch AF controls get more utility from the Olympus E-PL6.

Lens Systems and Optical Versatility

One big advantage the Olympus E-PL6 holds is its Micro Four Thirds lens mount, which supports a vast ecosystem of 107 lenses - including primes, zooms, macros, and specialty optics from Olympus and third parties. This lets photographers tailor their kit precisely: airy fast f/1.8 primes for portraits, rugged zooms for travel, or stellar macro lenses for detail work.

The Sony TX9, by contrast, has a fixed focal length zoom lens covering 25-100 mm equivalent (4x zoom) with variable aperture f/3.5-4.6. Its lens is versatile for general snapshots but inherently limited creatively compared to interchangeable lens systems.

In practical use, the Olympus setup delivers sharper images, better low-light capability due to faster maximum apertures, and the option to swap lenses for different genres - including wildlife, macro, or cinematic video. The Sony’s integrated lens keeps complexity low but at the inevitable cost of image quality and artistic control.

For anyone serious about growing their photographic skills or exploring diverse genres, the E-PL6’s Micro Four Thirds lens flexibility is irreplaceable.

Autofocus Systems Compared

Autofocus accuracy, speed, and versatility make or break many photographic opportunities, especially action or wildlife photography. Testing both cameras with moving targets and static subjects under various lighting revealed clear differences.

The Olympus E-PL6 employs a contrast-detection autofocus with 35 focus points and face detection, supporting continuous AF and tracking modes. While lacking phase-detection AF (a limitation common in its era), the system remained reliable and precise for most situations, including eye detection on human subjects (but no animal eye AF).

The Sony TX9’s autofocus uses contrast detection on 9 points, with continuous focus limited, and face detection disabled. Its smaller sensor combined with slower focus drives meant hunting was more frequent, especially in dimmer light or moving subjects.

In burst shooting, the Olympus shoots up to 8 frames per second continuously, outperforming the Sony’s 10 fps burst by sheer autofocus tracking quality - the Sony actually slows down due to focus lag.

The conclusion: for portraits, wildlife, or sports where AF reliability counts, the Olympus E-PL6 is a more capable assistant. The TX9 is better suited for static subjects or casual snaps.

Real-World Photography Discipline Evaluations

Let’s review how both cameras perform across specific photographic genres and use cases that many readers will find immediately relevant.
