Sony QX1 vs Sony W570: A Deep Dive into Two Very Different Cameras

When diving into the Sony lineup, you quickly discover a range of camera designs and purposes that cater to dramatically different users. Today, I’m putting the Sony Alpha QX1 (QX1) and the Sony Cyber-shot DSC-W570 (W570) head-to-head. At first blush, these cameras could not be more different - one is a lens-style, mirrorless APS-C shooter, the other a pocket super-compact point-and-shoot - yet both come from Sony and target mobile-age photography consumers. After hours of hands-on testing and side-by-side comparison, I’ll guide you through their nuances, strengths, weaknesses, and ultimately, which camera might deserve a spot in your bag.

Understanding the Designs: Lens-Style Versus Ultracompact

Before diving into specifications and image quality, let's cover the physical approach each takes. The Sony QX1 uses a so-called lens-style design. That's a mirrorless APS-C sensor housed in what looks like a large lens, designed primarily to pair with a smartphone for control and image preview. There is no traditional body with viewfinder or physical grip - making it strikingly compact (74x70x53mm) and lightweight at 216g, but also fundamentally different in usage compared to most cameras.

Contrast that with the Sony W570, a tiny ultracompact point-and-shoot (91x52x19 mm; 116g), designed to be pocketable and simple. It integrates its lens, controls, and touchscreen into a minimalist shell that requires no pairing or smartphone app.

It’s a classic example of two divergent philosophies: the QX1 aims to deliver DSLR-style image quality in a novel form factor; the W570 prioritizes portability and ease of use.

Sensor Technology and Image Quality: The Foundation of Performance

Image quality hinges on sensor technology first and foremost. Here lies the most profound difference between these cameras.

The Sony QX1 sports a 20MP APS-C sized CMOS sensor, measuring 23.2x15.4 mm and boasting a sensor area of approximately 357 mm². In contrast, the Sony W570 uses a much smaller 1/2.3-inch CCD sensor (6.17x4.55mm, 28 mm²) with 16MP resolution.

From my experience - as anyone who's shot with compact cameras before knows - there is no contest here. The QX1’s larger sensor enables vastly superior low-light performance, improved dynamic range, and the ability to capture detail and tonal gradations with much greater fidelity. In real-world testing, images from the QX1 show significantly less noise at ISO 1600 and above compared to the W570’s early roll-off at ISO 800 and 1600.

The QX1 also supports 16-bit RAW output, providing maximum post-processing flexibility, whereas the W570 shoots only JPEG, limiting creative latitude for professionals or enthusiasts who rely on editing.

For landscape photographers who prioritize resolution and dynamic range, the QX1’s sensor excels at capturing the full tonal range of skies and foreground details - a pronounced advantage over the W570.

Autofocus and Shooting Performance: Speed vs Simplicity

Autofocus systems are a pivotal differentiator that influences how these cameras perform across varied subjects, especially moving ones.

The Sony QX1 employs a contrast-detection autofocus system with 25 focal points incorporating touch-based selection, face detection, and selective AF modes. While it lacks phase-detection AF - meaning autofocus speed and tracking aren’t as blistering as recent mirrorless cameras - it is nonetheless sharp and accurate for most photography disciplines. Continuous AF tracking is not supported.

Meanwhile, the W570 offers a simpler 9-point AF array with contrast detection but without face detection or manual focus. It’s designed for straightforward point-and-shoot operation without demanding user input.

Testing both cameras on moving subjects - like street scenes or slow wildlife - the QX1's touch focus gave me precise control for selective AF on a cat’s eyes or a bird’s contour, though speed was modest at around 4 frames per second continuous shooting. The W570’s autofocus struggles with fast-moving subjects and its single FPS continuous shooting mode limits burst opportunities.

Ergonomics and Controls: Handling in Practice

Image quality might win the battle, but handling and UI often determine if a camera becomes a daily favorite - or an occasional curiosity.

For the Sony QX1, the lack of a traditional camera body means no built-in viewfinder, grip, or extensive physical controls. It depends on pairing with a smartphone and using the app interface, which can feel unintuitive at first. Physical buttons are minimal, and the touchscreen interface on the camera is limited. The QX1’s weight and size make it extremely portable but also somewhat awkward for extended handheld sessions without additional grip accessories.

The Sony W570 is the classic point-and-shoot setup: a small body with a non-touch 2.7-inch Clear Photo LCD screen and dedicated buttons for power, zoom, shutter, and menu. Its compact size fits comfortably in the palm and pocket, and straightforward controls cater to beginners or casual users who want quick snapshots.

The W570’s LCD is small with modest resolution but sufficient for framing and reviewing images. The QX1 doesn’t have a screen of its own - it relies entirely on the smartphone display for composition and settings adjustment, which can be a limiting factor if you want a standalone camera experience.

Lens Options and Flexibility: The Power of the E Mount

One of the QX1’s greatest advantages is its compatibility with the Sony E-mount lens system, giving users a realm of creative possibilities. You’re not tethered to a fixed zoom lens.

The QX1 can accommodate any E-mount lens from Sony or third parties, spanning fast primes, ultra-wide zooms, telephoto, and macro lenses - empowering photographers to tailor the tool precisely to their needs. This extends its value for portrait, wildlife, macro, and even landscape work.

In contrast, the W570 comes with a fixed 25-125mm equivalent (5x zoom) lens with an aperture range of F2.6 to F6.3. While the optical zoom range is reasonable for casual shooting, it certainly lacks the sharpness and speed of prime lenses or professional zooms.

Battery Life and Storage

Battery endurance often impacts on-the-go photography, especially for travel and wildlife shooters.

The Sony QX1 uses the NP-FW50 battery pack, rated for about 440 shots per charge under standard conditions. Given its mirrorless heritage and external control via smartphone, battery management requires some thought as the phone’s battery also drains during shooting sessions.

The Sony W570 employs the NP-BN1 battery with unspecified official life, but real-world use suggests typical compact camera endurance - sufficient for casual users but not marathon shooters.

Storage-wise, the QX1 accepts microSD and Memory Stick Micro cards, while the W570 supports SD/SDHC/SDXC and Memory Stick Duo formats. While more cumbersome, the W570’s wider card support fits common user preferences.

Performance Across Photography Genres

Understanding how each camera performs across different photography areas can help clarify which device fits your needs.

Portrait Photography

Portraits demand good skin tones, bokeh quality, and reliable eye detection autofocus.

• QX1: Its large APS-C sensor combined with E-mount lenses enables shallow depth-of-field and beautiful subject isolation. Face detection autofocus helps get sharp eyes, although it's not as advanced as later Sony models with real-time Eye AF. The flexibility in lens choice (such as a 50mm f/1.8 prime) unlocks creamy bokeh unmatched by the W570.

• W570: Given its small sensor and fixed zoom with slow aperture in telephoto, portraits are softer with limited background separation. Face detection autofocus is absent, requiring steady hands and good light.

Landscape Photography

Landscape shots call for wide dynamic range, high resolution, and solid weather resistance.

• QX1 produces crisp 20MP images with broad dynamic range, preserving highlight and shadow information even in challenging conditions. However, it lacks weather sealing, so caution is advised in adverse environments.

• W570’s 16MP CCD sensor can render respectable daylight landscapes but with reduced dynamic range and lower resolution. No weather sealing either.

Wildlife and Sports Photography

Fast autofocus, high frame rates, and telephoto reach are critical here.

• QX1: thanks to E-mount compatibility, you can pair it with powerful telephoto lenses (e.g., 70-300mm f/4.5-5.6). However, autofocus speed and burst rate of 4 FPS are modest. It suits slower-moving wildlife or carefully composed sports shots, but won’t keep up with pro-level tracking.

• W570: Weak autofocus and only 1 FPS continuous shooting make it unsuitable for action or wildlife photography.

Street and Travel Photography

Portability, discretion, and ease of use are key.

• W570 shines here with its pocketable size, quiet operation, and intuitive experience. LTE-style lenses keep it versatile for a variety of street scenes. However, smaller sensor means noisier images in low light.

• QX1 is somewhat bulkier without a grip and requires smartphone tethering, which can be less spontaneous but offers higher image quality - if you’re prepared to carry extra gear.

Macro Photography

The ability to focus close and capture fine details.

• QX1’s lens flexibility allows dedicated macro optics, yielding excellent magnification and sharpness.

• W570 offers a 5cm macro focus range but with limited sharpness and background separation.

Night and Astro Photography

High ISO performance and exposure flexibility matter.

• QX1 excels with its low-light capability (native ISO 100-16,000) and manual control modes.

• W570 struggles at anything beyond ISO 800, leaving images noisy and washed out in dark conditions.

Video Capabilities

Video is a significant factor for many users.

• QX1: Full HD (1920x1080) at 30p, MPEG-4 format. No microphone or headphone ports present, and no 4K support. Lacks in-body stabilization.

• W570: Limited to HD 1280x720, 30fps video. Basic video quality suitable for casual capture.

Build Quality and Weather Sealing

Neither camera offers weather sealing or rugged construction. The QX1's compact size and plastic lens-style shell are somewhat fragile, while the W570, typical of ultracompacts, is modestly sturdy but not designed for harsh conditions.

Think of both as best used in controlled environments or protected conditions.

Connectivity and Wireless Features

Both feature wireless connectivity but differ in implementation.

• QX1 has built-in Wi-Fi and NFC to interface seamlessly with smartphones for remote control and image transfer.

• W570 supports Eye-Fi wireless memory cards for wireless image transfer, which is a more clunky and outdated solution.

USB 2.0 ports on both offer wired connectivity, but only the W570 has HDMI output for direct TV viewing.

Price-to-Performance Analysis: Value for Your Investment

At MSRP ~$500, the QX1 offers entry-level APS-C performance with flexibility, suitable for enthusiasts wanting to experiment with mirrorless lenses in a highly compact form factor. Its strengths in image quality and lens ecosystem provide great value - though the reliance on smartphone integration may deter traditionalists.

The W570 was priced around $160 at launch, positioning it squarely in the budget ultracompact market. Its strengths lie in portability and simplicity; image quality and features are basic but acceptable for snapshots and casual users not wanting to fuss with settings or bulky gear.
