Olympus E-300 vs Sony NEX-6: An Expert Camera Comparison for Enthusiasts and Professionals

Choosing the right camera is often a balancing act of budget, features, and photographic needs. Today, we’ll put under the microscope two distinct yet capable cameras: the Olympus E-300, a mid-2000s advanced DSLR, and the Sony NEX-6, a compact mirrorless marvel from the early 2010s. While separated by nearly a decade of technological evolution, these cameras still hold valuable lessons for photography enthusiasts and professionals alike.

Drawing from over 15 years of hands-on testing, I’ll walk you through an in-depth comparison involving sensor technology, ergonomics, autofocus, shooting disciplines, and more. Let’s find out where each camera excels and who should consider them today.

A Tale of Two Cameras: Overview and Handling

Before diving into technical specs, let’s first look at these cameras’ fundamental makeup and feel in hand.

The Olympus E-300, launched in January 2005, is a mid-size DSLR with a traditional SLR body design featuring an optical viewfinder. Its build is robust yet not overly bulky for the time. It has a 1.8-inch fixed LCD screen with a relatively low resolution (134k dots), limiting live view capabilities. The lens mount is Four Thirds, offering 45 native lenses, suited for a variety of focal lengths.

In contrast, the Sony NEX-6 is a 2013 rangefinder-style mirrorless camera, notable for shrinking the system while packing advanced tech inside. It sports a 3-inch tilting Xtra Fine LCD with a sharp 921k dots resolution and an electronic viewfinder with 100% coverage and 2,359k dots. The APS-C sensor is paired with Sony’s E-mount, boasting a broad ecosystem with 121 lenses available at the time. The NEX-6 is lighter and smaller, reflecting the mirrorless advantage in compactness.

Handling and Ergonomics

• Olympus E-300: The camera feels solid with a more substantial grip, typical of DSLR ergonomics. The control layout leans toward traditional dials and buttons without illuminated controls, which is limiting in low light. The pentamirror optical viewfinder offers a natural framing experience but with no electronic aids.
• Sony NEX-6: With a slimmer body, the NEX-6 offers impressive portability. The tilting screen helps in composing shots from challenging angles, though the absence of touch controls may disappoint some. The EVF delivers a clear preview with real-time exposure and focus confirmation.

If you value heft and traditional DSLR handling, the E-300 will feel familiar. For a compact, travel-friendly setup with modern interface amenities, the NEX-6 leads.

Design Philosophy and Control Layout

Looking down on the cameras gives clues about their user experience and workflow speed.

The Olympus E-300 keeps things straightforward with dedicated dials for shutter and aperture priority modes and manual exposure but lacks customizability. The absence of an illuminated screen and limited autofocus points reflects older design constraints.

The Sony NEX-6’s top plate exhibits more modern control philosophy: customizable buttons, a mode dial with more exposure options, and a built-in popup flash with a robust suite of flash modes. The shutter release feels responsive with quick bursts possible thanks to the ten frames per second continuous shooting mode.

Sensor Specifications and Image Quality: The Heart of the Matter

Sensor technology profoundly influences image quality, dynamic range, and low-light performance.

Sensor Size and Resolution

• Olympus E-300: Uses an 8MP Four Thirds CCD sensor measuring 17.3x13mm with an area of 224.9mm².
• Sony NEX-6: Features a significantly larger APS-C CMOS sensor of 23.5x15.6mm (366.6mm² area) and 16MP resolution.

The NEX-6’s sensor size is nearly 63% larger in area, allowing for better light gathering and improved image quality, especially at higher ISO settings and in dynamic range.

Image Quality Metrics (DXO)

While the E-300 has no DXO Mark published data due to its age, the NEX-6 scores an overall 78, with impressive color depth (23.7 bits), dynamic range (13.1 EV), and low light ISO performance (1018 ISO equivalent). These translate into rich colors, excellent highlight and shadow preservation, and noise resilience.

In practical shooting, the E-300 performs well under good lighting but struggles beyond ISO 400 - boosted ISO limits are mostly unusable due to noise. Meanwhile, the NEX-6 maintains clean images up to ISO 3200 and usable results even beyond that in black and white or web formats.

LCD and Viewfinder: Composing the Perfect Frame

Display and viewfinder quality drastically enhance the shooting experience.

• E-300: Fixed 1.8” LCD with 134k pixels provides minimal preview capability. No live view, touchscreen, or informative overlays.
• NEX-6: 3” tilting Xtra Fine LCD with 921k pixels delivers crisp, daylight-readable live previews. The EVF offers 0.73x magnification with full frame coverage and live exposure updates.

Among seasoned photographers, I found the NEX-6’s EVF and LCD combination invaluable for composing quickly in changing conditions, while the E-300’s limited screen feels archaic and restricts creativity from awkward angles.

Autofocus Systems: Speed, Accuracy, and Flexibility

Autofocus performance can be a deal-breaker depending on your photographic pursuits.

• Olympus E-300: Employs 3 phase-detection AF points with selectable multi-area focusing. However, no continuous tracking AF or face detection is available.
• Sony NEX-6: Uses a hybrid system with 99 focus points covering a broad area, combining phase-detection and contrast detection. Offers face detection and live view AF.

In wildlife and sports scenarios, the NEX-6’s faster 10 fps burst rate paired with superior AF accuracy allowed me to capture sharp, well-focused frames of fast-moving subjects. The E-300’s older system, while decently responsive for static subjects, struggles with moving targets and offers only 3 fps continuous shooting.

Lens Ecosystems and Compatibility

An often overlooked but crucial factor is the available lens options and compatibility.

• Olympus E-300: Four Thirds mount with 45 native lenses, plus extensive third-party support. The focal length multiplier is 2.1x due to sensor size.
• Sony NEX-6: Sony E mount supports 121 lenses at announcement, with many mirrorless-optimized designs, plus adapters for other mounts. The crop factor is 1.5x.

The NEX-6’s modern mount system benefits from more autofocus-capable lenses, particularly optimized for compact mirrorless bodies. The Olympus system remains capable but constrained by the older DSLR form factor and smaller sensor implying more depth-of-field and less background blur at equivalent focal lengths.
