Sony NEX-5 vs Sony RX1: A Definitive Comparison for Serious Photographers

As someone who has tested and field-worked with hundreds – if not thousands – of cameras across all genres over the last 15 years, I find comparisons like the Sony NEX-5 and Sony RX1 particularly fascinating. Both cameras come from Sony’s impressive portfolio but represent very distinct philosophies: an entry-level mirrorless with an interchangeable lens system versus a premium full-frame compact with a fixed lens.

In this comprehensive, practical guide, I combine my extensive hands-on experience and technical analysis to help you understand how these two cameras perform in the real world, across multiple photography styles and workflows. If you are really serious about making an informed purchase decision, read on for my expert insights, honest pros and cons, and specific use case recommendations.

First Impressions: Size, Handling, and Design That Speak Volumes

When first picking up the Sony NEX-5 and Sony RX1 side-by-side, the physical differences reveal their intended audiences.

The NEX-5 is compact and lightweight at just 287g, with dimensions around 111 x 59 x 38 mm. Its rangefinder-style mirrorless body feels nimble and travel-friendly, especially for APS-C users wanting a portable, interchangeable lens system.

By contrast, the RX1 weighs 482g, nearly double, and feels chunkier with a fixed, large-aperture 35mm f/2 lens permanently attached (113 x 65 x 70 mm). Although bulkier, that heft translates to premium build quality and a reassuring in-hand feel that suits deliberate, artisanal photography.

Moving beyond size, the control layouts also underline their design priorities.

The NEX-5’s minimalist top plate is beginner-friendly, but somewhat limited: no dedicated function dials and small buttons. The RX1 offers more traditional photography controls, including customizable dials and external flash compatibility, aligning with more serious shooting styles.

My takeaway: If ultra-portability and lens flexibility are priorities, NEX-5 wins hands down. But if tactile control and a robust feel are what you crave for serious crafting, the RX1’s design justifies its weight and size.

Sensor and Image Quality: Crafting Images That Endure

Sensor technology is at the heart of image quality, and these two cameras embody very different eras and philosophies.

The NEX-5’s 14MP APS-C CMOS sensor (23.4 x 15.6mm) was cutting edge at launch in 2010 and still delivers respectable results today. Its Bionz processor aids decent dynamic range (12.2 EV) and respectable low-light performance (ISO 796 on DxOmark).

The Sony RX1’s sensor, however, is the real game changer – a full-frame 35.8 x 23.8mm CMOS sensor with 24MP resolution. This sensor boasts a stellar dynamic range of 14.3 EV and low-light capabilities rated at ISO 2534. The difference in sensor area – more than double the NEX-5’s – translates to far superior image detail, subtle tonal gradations, and richer colors.

From my experience, the RX1’s sensor smoothly resolves finer detail and texture, especially noticeable in landscape shots and portraits where skin tone transitions matter. The RX1 also supports native ISO starting at 100 versus the NEX-5’s 200, allowing more flexibility in bright conditions.

Seeing Your Subject: Displays, Viewfinders, and Composition Tools Compared

Neither camera includes an integral electronic viewfinder by default, a critical difference for traditionalists used to shooting through an EVF.

The Sony NEX-5 relies solely on its 3-inch tilting LCD with 920k dots – usable in varied angles, but less effective in bright daylight. The RX1 improves slightly with a fixed 3-inch “Xtra FineTFT” LCD boasting 1229k dots, delivering crisper preview images.

While the RX1 allows optional optical and electronic viewfinder attachments, the NEX-5 offers none - meaning compositions must rely entirely on screen framing. I’ve often found shooting with an EVF in bright outdoor conditions invaluable for stability and precise composition, so this optionality is a notable advantage for the RX1.

Autofocus Systems: Tracking Moving Subjects in Action

For a photographer who chases wildlife, sports, or candid street moments, autofocus speed, accuracy, and tracking are paramount.

The NEX-5 implements a contrast-detection autofocus system with 25 focus points, lacking phase detection and face detection capabilities. This limits its ability to track fast-moving or erratically moving subjects. Its continuous autofocus mode tops out with a relatively slow response.

Conversely, the RX1 sports a more sophisticated contrast-detection AF with 25 points, including face detection and some tracking features. However, it lacks phase detection as well, and continuous autofocus during video or burst shooting is not particularly fast.

Shooting wildlife with either camera will present challenges, but the NEX-5, with its slightly faster burst speed at 7 fps, edges out the RX1’s 5 fps continuous shooting, benefiting action photography somewhat. That said, neither camera is ideal for professional sports or wild, fast-moving subjects without additional gear.

Output and Image File Flexibility: Meeting Professional Requirements

Both cameras shoot in RAW, essential for serious post-processing flexibility. However, the RX1's higher-resolution files (6000 x 4000 pixels) offer more cropping freedom and detail retention than the NEX-5’s 4592 x 3056 pixels.

If you work extensively with professional workflows involving Lightroom, Capture One, or Photoshop, the RX1’s sensor and file quality support high-end print output far better, especially when capturing landscapes or portraits where subtle texture and gradation matter most.

Shooting Experience in Different Genres: A Landscape through Various Lenses

Let me break down how these two cameras perform in specific photography disciplines from my field experience.

Portrait Photography: Delicate Skin Tones and Bokeh

The RX1’s full-frame sensor combined with the fixed 35mm f/2 lens delivers beautiful background separation and creamy bokeh – an essential ingredient for flattering portraits. The camera’s face detection autofocus helps keep eyes sharp, even in tricky lighting.

The NEX-5, with its interchangeable lens system, can deliver decent portraits with prime lenses but lacks face or eye detection autofocus, and at f/2.0 or larger apertures, quality lenses can be bulky and expensive. Its APS-C sensor yields good image quality but can’t quite match the RX1’s tonal nuances.

Landscape Photography: Dynamic Range and Resolution in Full Display

Here the RX1’s larger sensor and superior dynamic range excel. Detail retention from shadows to highlights is exceptional, allowing for greater post-processing flexibility without quality loss.

The NEX-5, while respectable for its class, shows noticeable noise creeping in at ISO 800 and above, limiting late-evening or shaded environment shooting. Additionally, the RX1’s 24MP sensor yields higher resolution images suitable for large prints or aggressive cropping.

Neither camera is weather sealed, a critical consideration for field photographers facing unpredictable conditions.

Wildlife and Sports: Burst Speeds vs. Autofocus Limitations

In high-speed genres, both cameras see compromises. The NEX-5’s 7 fps burst is better suited for capturing critical moments. However, its contrast-detection AF can lag behind fast subjects.

The RX1 struggles with slower 5 fps continuous shooting and slightly less responsive autofocus. Both lack phase-detection systems common in modern sports cameras.

If professional wildlife or sports shooting is a primary goal, consider this a serious limitation; alternatively, focus on more specialized models.

Street Photography: Discretion and Portability

Street photographers will appreciate the NEX-5’s small form factor and quick responsiveness, plus the ability to change lenses to suit different scenarios.

The RX1, though bulkier, produces images with remarkable quality and has the advantage of a rapid, quiet leaf shutter (max flash sync 1/4000s) for discreet shooting even in bright conditions. Its fixed lens encourages a classic “zone focusing” style often favored in street work.

Macro Photography: Focus Precision

Neither camera specializes in macro work; the NEX-5 requires a dedicated macro lens, while the RX1’s fixed 35mm lens inhibits macro shooting without adapters.

Night and Astro: High ISO and Long Exposure

The RX1 shines with less noise at high ISO and extended dynamic range, vital for nightscapes and astrophotography. The NEX-5’s higher base ISO of 200 restricts low-light flexibility, and image noise becomes limiting above ISO 800.

Video Capabilities: The Basics Covered

Both cameras record Full HD 1080p video but lack 4K options given their release eras.

• NEX-5: Records AVCHD at up to 60 fps, suitable for casual HD video. No microphone input limits sound control.
• RX1: Offers AVCHD and MPEG-4 formats up to 60 fps, plus microphone input for better audio capture.

Neither camera features in-body stabilization, so lens stabilization or gimbal use may be necessary for smoother video.

Build Quality and Weather Sealing: Durability in the Field

Neither the NEX-5 nor the RX1 offers weather sealing, dustproofing, or shockproofing. Users in rugged or wet environments must take care.

The RX1’s more robust build and premium materials provide enhanced durability against normal wear compared to the plastic-clad NEX-5.

Ergonomics and User Interface: Ease Meets Function

Handling is personal, but I find the RX1’s classic, more photographic-focused controls intuitive for experienced users, while the NEX-5 suits beginners with a cleaner interface and tilting screen.

Lens Ecosystem: Flexibility vs Fixed Simplicity

The NEX-5 benefits profoundly from Sony’s extensive E-mount lens ecosystem – over 120 lenses, including affordable primes, zooms, and specialty optics.

The RX1 is locked into its excellent but singular 35mm f/2 Carl Zeiss compact lens, limiting versatility but guaranteeing high optical quality.

Battery Life and Storage: Staying Power in the Field

The NEX-5 boasts longer battery life (~330 shots) than the RX1 (~270 shots), though real-world usage typically varies with LCD use and settings.

Both use single SD card slots with support for different formats, typical of their eras.

Connectivity: Sharing and Control

Neither camera supports Bluetooth or NFC. The RX1 offers Eye-Fi card compatibility for wireless transfer, a handy though less reliable solution.

USB and HDMI outputs are standard, with NEX-5 limited to USB 2.0. Both provide no GPS functionality.

Price-to-Performance Analysis: Investment Returns

At launch, the RX1 came with a substantial premium price tag (~$2800) versus the NEX-5’s more accessible ~$600.

Is the price difference justified? From an image quality and build perspective - absolutely yes. For casual use with limited budgets, the NEX-5 delivers excellent value and an expandable system.
