Sony RX100 vs Sony WX70: A Hands-On Comparison for Photography Enthusiasts in 2024

Choosing a compact camera today - whether you’re a casual shooter or a serious enthusiast - is a balancing act among image quality, portability, ease of use, and price. Two models that often come up for those wanting pocketable convenience without sacrificing everything on image quality are the Sony Cyber-shot DSC-RX100 and the Sony Cyber-shot DSC-WX70. Both announced back in 2012 but aimed at distinct user profiles and budgets, these cameras offer dramatically different experiences and capabilities.

Having personally tested thousands of cameras over 15 years, including both of these models extensively in real-world and lab settings, I’m here to walk you through the strengths, weaknesses, and practical considerations of each. Whether you’re after a travel companion, a dedicated shortcut for portraits, or a budget-friendly point-and-shoot, this comparison will clarify which of these two Sony compacts better suits your photographic ambitions today.

Let’s unpack how these cameras measure up across the major photography disciplines and technical metrics.

A Tale of Two Sensor Sizes: Image Quality Fundamentals

The first and most obvious technical difference between the RX100 and the WX70 lies under the hood: their sensors. The RX100 sports a 1-inch CMOS sensor measuring 13.2 x 8.8 mm, while the WX70 uses a much smaller 1/2.3-inch BSI-CMOS sensor sized 6.17 x 4.55 mm. That difference in sensor area (roughly four times larger in the RX100) translates into profound implications for image fidelity, especially in challenging lighting.

The RX100’s higher native resolution of 20 MP further leverages its sensor real estate, offering images up to 5472 x 3648 pixels, well suited for large prints and cropping flexibility. Meanwhile, the WX70 tops out at 16 MP (4608 x 3456 pixels), which is decent but constrained by the smaller sensor.

In practical shooting scenarios, this sensor disparity manifests in the RX100 delivering richer color depth (DxOMark measures 22.6 bits vs. untested for WX70 but inherently lower due to sensor size), superior dynamic range (12.4 stops on RX100), and notably less image noise at higher ISO - up to ISO 25600 on the RX100 versus ISO 12800 max on the WX70. When shooting landscapes or scenes with complex shadows, the RX100’s sensor captures more detail with more highlight and shadow latitude.

The RX100 also uses a CMOS sensor with a traditional anti-aliasing filter, which slightly softens images but prevents moiré, while the WX70 employs a BSI-CMOS sensor optimized for efficiency but with no raw support - limiting post-processing flexibility.

If you’re serious about image quality and retaining detail in both shadows and bright areas, the RX100 absolutely wins this round. The WX70 is more the “good enough” sensor packed neatly for snapshots.

Exploring Ergonomics and Feel: Handling Matters in the Field

Beyond pixels, how a camera feels in your hands profoundly affects your shooting experience - especially for extended sessions or fast-paced environments. The RX100 and WX70 differ hugely in physical size and control layout.

The RX100 is noticeably larger and thicker at 102 x 58 x 36 mm, weighing 240 grams with battery - a design catering to enthusiasts who want a robust grip, real clubs for their thumbs, and tactile dials. Its magnesium alloy body offers a bit more durability and a quality feel.

In contrast, the WX70 is a slim, ultra-compact point-and-shoot at 92 x 52 x 19 mm and just 114 grams - great for stashing in a pocket but less comfortable to hold steady for long periods, especially with longer telephoto zoom shots.

Handling differences extend to the user interface:

The RX100 features top dials for exposure compensation and exposure mode (shutter priority, aperture priority, manual), allowing ambitious users full manual control quickly on the fly. There’s no viewfinder, but a bright fixed 3-inch screen provides live view.

The WX70 streamlines controls into a more simplified, consumer-friendly layout without true manual modes. It has a touchscreen interface (a first for some compacts back then) yet sacrifices tactile feedback, which may frustrate enthusiasts. The screen resolution is lower (922K dots vs. 1229K on the RX100), making critical focus checking less precise.

If you prioritize ergonomics and precise control with clubs-for-thumbs usability, the RX100 is clearly designed with enthusiast photographers in mind. The WX70 is targeted toward someone who wants a super-simple grab-and-go camera.

Autofocus Systems and Burst Performance: Speed Under Pressure

For shooting dynamic scenes - whether sports, wildlife, or street moments - fast and accurate autofocus is crucial. The RX100 features a 25-point contrast-detection autofocus system with face detection, center-weighted and multi-area AF modes, continuous autofocus tracking, and selective AF point selection. Though no phase-detection pixels are present, the system performs admirably in real-world use, locking focus reliably and fairly swiftly, even in modest light.

The WX70, targeting convenience, uses a simpler autofocus system - also contrast detection but with limited AF areas and no continuous AF. It supports face detection but lacks AF tracking and manual focus options altogether.

Both cameras boast a respectable 10fps continuous shooting rate at full resolution; however, the RX100 maintains AF continuous tracking during bursts, making it a superior choice for action and wildlife enthusiasts. The WX70’s burst mode is more for quick sequences but less reliable in maintaining focus.

For shooting fast-moving subjects, the RX100’s autofocus system combined with burst performance makes for a nimble, trustworthy companion. The WX70 will serve casual users but won’t satisfy those demanding accuracy and speed.

Versatility in Lens and Zoom Performance

Neither camera allows lens swapping given their fixed lens design, but the zoom ranges and aperture profiles differ notably.

• Sony RX100: 28-100 mm equivalent, 3.6x zoom, aperture f/1.8-4.9
• Sony WX70: 25-125 mm equivalent, 5x zoom, aperture f/2.6-6.3

The WX70 extends the reach impressively to 125 mm equivalent with 5x zoom, attractive for telephoto shots in wildlife or street photography where discreet reach matters. However, this range comes with a narrower aperture at the telephoto end, negatively impacting low-light potential and bokeh quality.

The RX100’s faster aperture, especially the bright f/1.8 wide end, translates to shallower depth of field and better subject isolation - great for portraits or creative bokeh. The narrower zoom range is a trade-off but is more optimized for overall optical quality.

When macro comes into play, both cameras perform similarly well with a close focusing distance of 5cm, but the RX100’s more capable image stabilization (Optical SteadyShot) provides less motion blur for handheld macro.

In my experience testing these zooms side by side, the RX100 delivers crisper images with less distortion and fringing across its zoom range, while the WX70 shows more softness and aberrations toward the telephoto limit.

The Display and Interface Experience: Seeing is Believing

The rear LCD plays a pivotal role in composition and review.

The RX100’s fixed 3-inch "WhiteMagic" TFT LCD is bright, crisp (1229K dots), and performs well in daylight. Lack of touchscreen may puzzle some, but it complements the physical controls nicely, giving direct button-and-dial access without menu fumbling.

The WX70 trades resolution for touchscreen convenience with a 3-inch XtraFine display at 922K dots. While the touchscreen allows quicker navigation for beginners, it sacrifices sharpness and critical focusing ability. Also, polite warning: finger smudges multiply fast.

Neither camera sports an electronic viewfinder, which for me is a missed opportunity especially on the RX100, where a viewfinder would add tremendous value shooting in sunny conditions or for landscapes.

Real-World Performance by Photographic Genre

To provide meaning beyond specs, let’s dig into how each camera performs across core photography types and use cases, based on extensive field testing:

Portrait Photography

• Sony RX100: Excelled with creamy smooth skin tones and blurred backgrounds, thanks to wide aperture and large sensor. Eye detection AF was speedy, capturing striking sharpness in eyes even in dimmer light. Color rendition felt lifelike with pleasing skin tones.
