Sony NEX-5R vs Sony RX100 III: A Real-World Matchup of Two Beloved Sony Cameras

Sony fans, camera enthusiasts, and shutterbugs alike have probably heard of both these compact powerhouses: the Sony Alpha NEX-5R, an early mirrorless entry-level marvel from 2012, and the Sony Cyber-shot RX100 III, the pocketable large sensor compact from 2014. Both packed innovative tech for their generation, but how do these cameras really stack up when put side-by-side? Having spent many weeks testing each extensively across a broad range of photography genres and conditions, I’m excited to dive into the nitty-gritty details, share some personal observations, and - hopefully - help you figure out which of these Sony gems is right for you.

Let’s start things off with the basics.

Face the Size and Build: Who Wins the Hand-Held Battle?

When I first picked up these cameras, the ergonomics immediately shaped my initial impressions. The Sony NEX-5R is a rangefinder-style mirrorless camera with a relatively compact body that feels like an actual “camera,” not a glorified point-and-shoot. The dimensions at 111mm wide, 59mm tall, and 39mm deep and a weight of 276g make it a light workhorse that pairs well with the vast Sony E-mount lens arsenal.

The Sony RX100 III, on the other hand, is a large-sensor compact designed to slip unobtrusively into the pocket - just 102mm wide, 58mm tall, 41mm deep and tipping the scales at 290g. Despite its compactness, it’s weighted to feel reassuring rather than toy-like.

Holding the NEX-5R gives you a bit more grip and feels better for extended shoots or heavier lenses - comfort that paid off on long shoots, especially for portraits and landscapes. Meanwhile, the RX100 III trumps in portability - a legitimate “grab-and-go” companion that doesn’t scream “professional gear” (great for street photography and travel).

The top control layouts highlight the NEX-5R’s more traditional DSLR-inspired treatment with dials and buttons, whereas the RX100 III makes some concessions for its size with fewer physical controls but adds an excellent pop-up electronic viewfinder (EVF) that’s absent on the NEX-5R without buying additional accessories.

In essence, if you prize handling and lens flexibility over compactness, NEX-5R takes the crown. But if pocketability and a stealthy profile are your appeals, RX100 III scores points.

Under the Glass: Sensor and Image Quality Showdown

Sony’s cameras often shine when it comes to sensor performance, but here the comparison gets interesting because of fundamental differences.

The NEX-5R boasts a 16MP APS-C CMOS sensor measuring 23.4 x 15.6mm, roughly three times larger surface area than the RX100 III’s 1-inch 20MP BSI CMOS sensor at 13.2 x 8.8mm. Larger sensors commonly mean better noise performance, dynamic range, and depth-of-field control - especially important for serious photographers.

And indeed, testing across ISO ranges revealed the NEX-5R’s sensor delivers greater dynamic range - measured at 13.1 EV stops versus 12.3 EV stops for the RX100 III - and superior low-light handling (ISO 910 vs. 495 in DxOMark scores). The color depth edges also favor the NEX: 23.7 bits vs 22.4 bits, indicative of richer tonal gradations, critical for nuanced portrait skin tones and subtle landscape hues.

On the flip side, the RX100 III ups the resolution game slightly with 20MP vs. 16MP, offering more detail potential - particularly useful for cropping or printing large in casual photography and everyday shooting scenarios.

Both cameras feature anti-aliasing filters to minimize moiré - a minor trade-off considering their sensor differences.

One small caveat: the RX100 III uses a backside-illuminated (BSI) sensor design that improves light gathering efficiency, explaining its relatively strong performance despite the sensor’s modest size.

In real-world shooting, the NEX-5R’s sensor delivered smoother gradations and cleaner shadows in landscapes and portraits. But the RX100 III offers pleasing detail and respectable noise control inside a pocketable form factor, making it fun and rewarding in everyday shooting.

Eyes On Focus: Autofocus Systems Compared

Autofocus (AF) technology can make or break your shoot, so I gave both cameras plenty of exercises in fast-moving and tricky-light scenarios.

Sony’s NEX-5R employs a hybrid AF system melding phase and contrast detection, boasting 99 focus points. This combo delivers quick and accurate AF in good light, with support for continuous AF plus touch-to-focus. However, it does lack advanced eye-detection autofocus, which is now more common in modern cameras.

The RX100 III uses a contrast-detection-only AF with 25 points, but adds face and eye detection that worked well for me with portraits and street subjects.

While both achieve a respectable 10fps burst rate - a sweet spot for action and wildlife - the NEX-5R has the edge in tracking quality and accuracy due to its hybrid mechanism. I noticed fewer focus hunting issues with the NEX-5R in dynamic sports settings, whereas the RX100 III occasionally struggled to lock promptly on erratically moving subjects.

Nevertheless, for casual or travel photography and everyday snaps, RX100 III’s face and eye-detection eased framing candid portraits - especially when combined with the EVF for precise framing.

The LCD and Viewfinder Experience

The rear interface on a camera is your daily companion, and these Sony models couldn’t be more different.

The NEX-5R features a 3-inch touchscreen LCD with 920k dot resolution that can tilt up to 180° and down 50°, great for selfies and awkward angles. Despite being early tech (2012 era!), I found the touchscreen surprisingly responsive and useful for touch-to-focus and menu navigation.

The RX100 III houses a 3-inch LCD too but with a higher resolution (1229k dots) and a tilt mechanism that allows a similar range of motion. It lacks a touchscreen, which felt a bit dated but didn’t hamper usability thanks to logical button layouts.

The real highlight is RX100 III’s built-in pop-up electronic viewfinder - 1440k dots in resolution, 0.59x magnification, and 100% coverage - that outperforms the optional EVF you have to buy separately for the NEX-5R. For bright sunny days or precise manual focusing, this EVF is a godsend. I found myself naturally shifting to the viewfinder on the RX100 for street and action shots.

Overall, the NEX’s touchscreen surpasses the RX100’s non-touch LCD for interactiveness, but RX100’s integrated EVF significantly enhances compositional accuracy and confidence.

Lens Ecosystem and Flexibility: The Mirrorless Advantage

Mirrorless vs fixed lens is a fundamental difference here.

Sony’s NEX-5R uses the venerable Sony E-mount, compatible out of the box with a huge library of native and third-party lenses - 121 lenses and counting - including primes, zooms, macros, and professional G-Master optics. This lens ecosystem makes the NEX-5R far more versatile than the RX100 III, which sports a fixed 24–70mm F1.8–2.8 zoom lens.

That gorgeous bright zoom looks great for portraits, landscapes, and even moderate macro (5cm focusing distance), but you’re tethered to its native focal length and optical characteristics.

If you’re someone who enjoys experimenting with specialized lenses - be it telephoto for wildlife, ultra-wide for architecture, or fast primes for low-light portraits - the NEX-5R has no contest. This flexibility makes it not only a better learning tool but also a camera you can grow into professionally.

The RX100 III lens is a jack of many trades - good sharpness, versatile zoom, and reasonably fast aperture - but it can’t compete with the freedom of interchangeable lenses.

Build Quality and Weather Resistance

Neither camera was designed specifically for rugged, professional work with weather sealing, but each feels sturdy for their intended market.

Both devices lack official dust, freeze, or splash resistance, so careful handling outside is a must. The NEX-5R’s more solid feel, with a metal chassis and robust buttons, makes it a bit more confidence-inspiring for fieldwork.

The RX100 III’s compact body and integrated lens reduce vulnerability, but the pop-up EVF mechanism is a potential weak spot to be mindful of.

For landscape photographers venturing into less hospitable locations, I advise treating both carefully or opting for more weather-sealed options. That said, the NEX’s build lends to longer durability when coupled with proper lens hoods and care.

Battery Life and Storage Options

Battery life is one of those practical essentials often overlooked until mid-shoot battery warnings flash.

The NEX-5R’s NP-FW50 battery achieves a solid 330 shots per charge under CIPA standards, edging slightly ahead of the RX100 III’s NP-BX1 at 320 shots. In real life, I got closer to 280 shots on both before recharging, thanks to lots of live view and EVF use on the RX100 III.

Both cameras support fast SD/SDHC/SDXC cards and Sony’s Memory Stick format - fine for everyday use, but those shooting in bursts or 1080p video at full resolution will want speedier UHS-I or better cards to avoid bottlenecks.

Neither offers dual card slots, which pros might miss for backup purposes.

Video Skills: Who’s the Better Shooter?

Both cameras capture full HD 1080p video but with subtle differences that matter depending on your style.

The NEX-5R records 1080p at 60fps using AVCHD format, making smooth footages ideal for casual use, and offers manual exposure control during video.

The RX100 III jumps higher with 1080p up to 60p and 24p, plus an additional 720p slow-motion mode at 120fps and supports XAVC S codec alongside AVCHD and MPEG-4. This richer video format spectrum combined with optical image stabilization is a boon for handheld video recording - footage looks airy and stable rather than shaky.

Neither camera has microphone or headphone jacks, so serious filmmakers will need external rigs. But for casual vlogging or travel videos, RX100’s image stabilization and video options give it an edge.
