Olympus E-3 vs Sony NEX-5N: A Comprehensive Hands-On Comparison for Photographers

Choosing the right camera is a pivotal decision that shapes how you see and capture the world. Today, I’m diving deep into a nuanced comparison between two notable yet very different models from Olympus and Sony: the Olympus E-3, a trailblazing advanced DSLR introduced in 2008, and the Sony NEX-5N, an early mirrorless contender from 2011 that helped define the compact enthusiast category. Both cameras come from reputable manufacturers with distinct design philosophies and target audiences.

Over countless hours of testing - spanning studio portraits, landscape hikes, speed-intensive wildlife moments, and even the nuanced requirements of astro and macro shooting - I’ve evaluated how these cameras perform in real-world scenarios. My goal: to help you decide which system aligns better with your photographic priorities and workflow.

Let’s break it down.

First Impressions: Size, Handling, and Ergonomics

Stepping back, the Olympus E-3 is emphatically designed as a robust professional tool with a traditional DSLR form factor, featuring a pentaprism optical viewfinder and mid-size SLR build. In contrast, the Sony NEX-5N embraces a compact mirrorless approach with a rangefinder-like profile oriented toward portability and casual control.

At 142 x 116 x 75 mm and roughly 890 grams, the Olympus E-3 feels substantial and reassuringly solid in hand - qualities that resonate strongly with photographers seeking durability and tangible control. Its magnesium alloy body is weather-sealed for harsh conditions, enhancing confidence in field use.

In the same vein, the Sony NEX-5N measures far smaller (111 x 59 x 38 mm) and weighs about 269 grams, trimming a significant chunk of heft. Its slim, minimalist body targets street photographers, travelers, and casual enthusiasts prioritizing portability over ruggedness. The grip is modest but surprisingly ergonomic given its size.

Examining control layouts, the E-3 offers dedicated buttons and dials for quick exposure adjustments, shutter speed, aperture, and ISO, adhering to DSLR ergonomics - a boon during fast-paced shooting. Conversely, the NEX-5N keeps physical controls minimalistic, with a mode dial and multi-function dial but leans heavily on its tilting touchscreen for navigation. This touch interface is responsive but may not suit photographers seeking tactile confirmation in demanding or gloved conditions.

While the E-3’s extensive physical controls offer speed and precision, the NEX-5N’s compactness, aided by the tilting screen, is better tailored for casual or run-and-gun shooting. The choice here hinges on your priority - durability and physical control versus lightweight discretion.

Sensor and Image Quality: Four Thirds vs APS-C in Real Use

Image quality remains pivotal, arguably the linchpin of your shooting experience. The Olympus E-3 employs a Four Thirds CMOS sensor measuring 17.3 x 13 mm with a 10 megapixel resolution (3648 x 2736 pixels). The Sony NEX-5N opts for a significantly larger APS-C CMOS sensor of 23.4 x 15.6 mm, delivering 16 megapixels (4912 x 3264 pixels).

More than just numbers, sensor size influences dynamic range, noise performance, and depth-of-field control. The APS-C sensor’s 365 mm² area surpasses the E-3’s 225 mm², translating to larger photosites that capture more light and render finer tonal gradations.

Technical tests reveal the NEX-5N provides superior dynamic range (approximately 12.7 EV vs the E-3’s 10.5 EV), richer color depth (DxO Mark scores show 23.6-bit vs 21.6-bit), and higher native ISO capabilities (up to ISO 25600, with usable noise levels up to around ISO 3200-6400), compared to the E-3’s native maximum of ISO 3200 with usable performance tapering earlier.

This means shadow and highlight recovery is more robust on the Sony, particularly useful for landscape shooters coping with high-contrast scenes, while noise control favors the Sony in low-light contexts - something wildlife and night photographers will appreciate.

Real-world testing corroborates these findings: portraits from the NEX-5N show cleaner skin tones and finer gradients under complex lighting. The E-3’s images, while solid, tend to show earlier noise onset and a slightly narrower tonal palette.

However, the Four Thirds sensor player packs a punch in color accuracy and sharpness, partly due to the TruePic III processor optimizing output. Olympus’s in-body image stabilization further helps mitigate blur, especially for handheld shooting below 1/60s shutter speeds.

Viewing and Composing: Optical Pentaprism vs Electronic Viewfinder Options

Neither camera features an electronic viewfinder built-in, but their approaches vary significantly.

The E-3 employs a pentaprism optical viewfinder with 100% coverage and 0.58x magnification. This design gives photographers a clear, immediate, and lag-free view of their scene with natural color rendition and no electronic artifacts. Pentaprism finders are generally more comfortable over long shooting sessions and favored by professionals for reliable framing.

The Sony NEX-5N lacks a built-in viewfinder but offers an optional electronic viewfinder (sold separately). The camera mainly relies on its 3-inch, 920k-dot tilting TFT LCD screen as the primary composing tool. It includes touchscreen focusing capabilities, a useful advantage over Olympus’s more basic 2.5-inch fixed resolution articulating screen with only 230k dots.

The NEX-5N’s screen tilts upward to nearly 80 degrees and downward about 45 degrees, accommodating awkward angles and enhancing street photography or vlog-style shooting. The touchscreen also enables intuitive touch-to-focus and menu navigation.

The E-3’s optical finder and lower-res articulated screen present a more traditional experience: reliable but less flexible when composing from unusual viewpoints or in bright sunlight conditions where LCD glare can be problematic.

In summary, if you prioritize an optical viewfinder for direct eye-to-scene confirmation, the E-3 delivers. If versatility and touchscreen interaction matter more, especially on varied compositions, the NEX-5N leads.

Autofocus Systems: Speed, Accuracy, and Usability

Autofocus is the heart of decisive image capture. The Olympus E-3 features an 11-point phase-detection AF system with multi-area AF and selective spot focusing. However, it lacks modern eye-detection or animal eye AF, and tracking AF is not present.

Conversely, Sony’s NEX-5N employs 25 contrast-detection autofocus points with face detection enabled via live view. While the NEX-5N does not incorporate phase detection autofocus, its contrast detection combined with sophisticated algorithms provides accurate AF during live view and video. However, the system can struggle slightly with fast-moving subjects.

What does this mean in practical shooting?

• Sports and wildlife photography: The E-3’s 5 fps burst rate paired with phase-detection AF delivers reasonably snappy focusing and continuous AF capability, though advanced tracking is missing - significantly limiting performance on erratic subjects.

• The NEX-5N offers a faster 10 fps burst but relies on contrast detection autofocus, which can result in hunting or lag during quick focus transitions. No continuous tracking AF for moving subjects is available, though face detection helps portrait work.

I tested both cameras shooting birds in flight and street action. The E-3’s optical viewfinder allows swift eye focus acquisition, but the AF system sometimes falters on erratic wingspans. The NEX-5N’s contrast AO lags behind in speed, often missing a few frames but performing admirably in well-lit, less fast-motion scenarios.

In essence, neither camera is ideal for professional sports shooters, but the Olympus has a slight edge for faster mechanical AF and optical framing. The Sony’s strengths shine more in static and portrait subjects.

Lens Ecosystem and Compatibility: Flourishing or Limited?

Lens choices dictate a system’s versatility and creative range.

The Olympus E-3 uses a Four Thirds mount, compatible with 45 native lenses manufactured for this series. The system includes stellar professional-grade primes and telephotos designed for durability and weather resistance - designed to complement the camera’s rugged build.

The E-3’s 2.1x crop factor must be factored into focal length calculations - meaning a 50mm lens behaves like a 105mm equivalent - great for telephoto reach but restricting wide-angle options somewhat.

In contrast, the Sony NEX-5N embraces the burgeoning Sony E-mount, boasting a rapidly expanding lineup of 121 compatible lenses from Sony, third-party vendors like Sigma and Tamron, and manual-adapted optics from various legacy systems. The APS-C 1.5x crop factor offers a more balanced field of view.

The E-mount’s versatility is exceptional for users transitioning from DSLRs or wanting mirrorless adaptability. It also supports fast apertures and high-performance primes suitable for portraits, macro, and landscapes.

For photographers invested in legacy glass, the NEX-5N wins hands down with easy compatibility; for those committed to an all-weather, professional lens set, the E-3 remains highly attractive.

Shooting Across Genres: Strengths and Limitations for Photography Types

Portrait Photography

The NEX-5N’s superior sensor resolution, face detection AF, and color depth yield natural, pleasing skin tones. The large APS-C sensor’s shallow depth of field with fast lenses facilitates creamy bokeh, enhancing subject isolation.

The E-3, however, can generate pleasing skin tones with careful manual focus and lighting but may struggle with background separation due to the smaller sensor size. Its in-body image stabilization helps sharpness during handheld portraits but lacks advanced eye AF assistance.

Landscape Photography

Dynamic range is crucial here - NEX-5N’s broader range and higher megapixels offer point-for-point more detailed files for large prints and panorama cropping.

Weather sealing on the E-3 gives it a decisive advantage for landscape shooters venturing into challenging environments. The articulating screen also helps compose low-angle shots.

Wildlife Photography

Here, autofocus speed and burst rate are pivotal. The E-3’s ruggedness, 5 fps burst, and phase-detection AF edge it slightly ahead for outdoor wildlife, especially with long telephotos.

The NEX-5N’s faster 10 fps burst rate is promising but limited by contrast-detection AF speed. Its smaller size is beneficial for discreet, spontaneous wildlife scenes.

Sports Photography

Neither camera is ideal for high-level sports. The E-3’s 5 fps with phase detection is acceptable for moderate-paced sports, while the NEX-5N’s 10 fps burst helps capture fast sequences but with AF limitations.

Street Photography

The NEX-5N thrives here thanks to its small size, light weight, and quiet operation. The tilting LCD aids candid compositions.

The bulkier, noisier E-3 may draw attention and is less portable but offers the advantage of an optical viewfinder with zero lag.

Macro Photography

Olympus’s in-body image stabilization paired with sharp macro Four Thirds lenses benefits handheld macro work. Manual focus precision is essential, and the E-3’s focus confirmation aids accuracy.

The NEX-5N’s 16MP sensor and quick live view focus assist are advantageous, but lack of stabilization may require a tripod.

Night and Astro Photography

While the NEX-5N’s higher ISO ceiling and dynamic range offer cleaner, brighter results in low light, the E-3’s weather sealing lets astrophotographers shoot in harsher night environments.

Long exposures on both cameras require stable supports, but Sony’s higher ISO flexibility gives it the edge.

Video Capabilities: Legacy DSLRs vs Early Mirrorless

Video was not a designed priority for the Olympus E-3; it has no video capabilities.

The Sony NEX-5N, meanwhile, offers 1080p HD video at 60 fps, as well as lower resolutions with AVCHD recording. Its contrast-detection AF supports video focus, and the tilting screen facilitates creative angles. Lack of microphone inputs and buttery video stabilization limit its appeal for semi-professional videographers, but for casual users and vloggers, it’s a standout feature for the era.

Workflow Considerations: Storage, Connectivity, and Battery Life

Both cameras feature one storage slot - CF and xD cards for Olympus, SD and Memory Stick for Sony - covering mainstream needs.

The E-3’s USB 2.0 port supports raw file transfers, but the lack of HDMI or Wi-Fi limits tethering or instant sharing.

Sony’s inclusion of HDMI out and Eye-Fi wireless support allows better connectivity options for photographers wanting immediate transfer and remote control possibilities.

Battery life favors the NEX-5N (approx. 460 shots per charge) over the E-3’s unspecified but generally lower DSLR endurance.

Durability and Build Quality: Environmental Sealing Matters

The Olympus E-3’s weather sealing against dust and moisture alongside magnesium alloy body construction makes it far more robust in challenging professional environments. If you shoot outdoors regularly in rain, dust, or cold, the E-3 is a more trustworthy partner.

The Sony NEX-5N lacks such sealing and is vulnerable to environmental stresses, underscoring its design for casual or urban use.
