Fast forward six years to 2019, the RX100 VII arrived as the ultimate sophistication in compact, large sensor cameras, boasting cutting-edge autofocus, 4K video, and a versatile zoom. Having evaluated both extensively, I’m excited to break down the nuanced performance differences, real-world usability, and technological leaps between these two distinct models from Sony’s stable.

Whether you’re a collector interested in the evolution of compact imaging or a photographer pondering which Sony to own, my experience testing thousands of cameras worldwide will guide you through these two fascinating devices - covering every discipline from portraiture to wildlife, and everything in between.

The Foundations: Understanding the QX100 and RX100 VII Design Philosophies

Before we get to image quality and autofocus prowess, it’s important to grasp how distinct the form factors are - and how each reflects its era’s priorities.

The QX100 is essentially a lens-style camera intended to pair exclusively with a user’s smartphone, tethering via Wi-Fi and controlled through an app. At 63x63x56mm and weighing just 179 grams, it has no screen, no viewfinder, and minimal physical controls. Its entire interface relies on your phone, which transforms into its viewfinder, shutter trigger, and settings hub. This radical design was innovative but niche, privileging portability and smartphone integration at the expense of traditional camera handling.

Contrast that with the RX100 VII - a fully self-contained large-sensor compact at 102x58x43mm and 302 grams. It features a built-in 3-inch tilting touchscreen LCD and an electronic viewfinder, plus a robust array of physical controls (dials, custom buttons) that satisfy enthusiast and professional photographers alike. It embraces the “pocketable powerhouse” ethos, packing advanced image processing, a versatile 24-200mm zoom, and a flood of modern connectivity options in one polished body.

The ergonomic progression here mirrors the technological developments and shifting market expectations between 2013 and 2019. If ergonomics influence your shooting experience, the RX100 VII is clearly the powerhouse, though the QX100’s minimalism might appeal for certain casual use cases or smartphone-first workflows.

Sensor and Image Quality: The Heart of the Beast

One of the biggest keys to image quality is sensor performance, and both cameras use a 1-inch (13.2 x 8.8 mm) BSI-CMOS sensor, a step up from most compact cameras with smaller sensors, designed to deliver excellent resolution and low noise.

Both cameras offer roughly 20MP resolution with maximum output sizes of 5472×3648 pixels, which is ample for detailed prints and critical cropping. That said, the RX100 VII edges ahead in some crucial sensor-related areas:

• ISO Range: QX100’s native ISO caps at 6400; RX100 VII extends to 12800 (native) and can be boosted lower or higher - offering greater flexibility in challenging lighting.
• RAW Support: The RX100 VII supports RAW shooting, vital for professional-level post-processing control. The QX100 outputs only JPEGs, limiting dynamic range recovery and color grading potential.
• Color Depth and Dynamic Range: DxOMark analysis rates the RX100 VII’s sensor with a color depth of 21.8 bits and dynamic range of 12.4 EV, significantly superior to older sensor tech. While the QX100 hasn’t been formally tested by DxOMark, its older sensor technology lacks the refinements enabling this performance.

In practice, this means the RX100 VII’s images retain more detail in shadows and highlights and deliver cleaner high ISO shots. During extended testing shooting landscapes and low-light scenarios, I noticed the RX100 VII’s files are better suited for creative work after capture, with more latitude in exposure correction and color nuance.

The QX100 still produces attractive images in good light and benefits from a fast f/1.8 aperture at 28mm (equivalent), but it feels more limited in demanding conditions. For casual snapshots or smartphone augmentation, it may suffice - but serious photographers will want the RX100 VII sensor’s advanced capabilities.

Autofocus: From Basic Contrast to Sophisticated Eye and Animal Detection

Autofocus makes or breaks a camera’s usability, especially in dynamic environments.

The QX100 offers very basic contrast-detect AF with face detection but no continuous AF, tracking, or sophisticated subject recognition features.

The RX100 VII, however, integrates Sony’s latest hybrid autofocus system - combining phase detection pixels covering 68% of the frame with contrast detection - to deliver incredibly fast and accurate performance, even on moving subjects. Critical features include:

• Real-time Eye AF for humans and animals (a particular thrill to test on wildlife).
• Reliable continuous AF tracking capable of 20 fps burst shooting with full AF/AE (amazing responsiveness).
• Multiple selectable autofocus areas, allowing precise control and creative framing.

In my wildlife and sports testing - such as photographing birds in flight or fast-moving soccer players - the RX100 VII’s AF kept up with ease, rarely missing focus. The QX100’s simpler AF means it’s better suited to still subjects or slower scenes.

This difference alone defines the niche each camera occupies: the QX100 for casual use and smartphone hybrid shooters, and the RX100 VII for enthusiasts who expect professional-grade AF performance in a compact package.

Build Quality, Controls, and Usability

Sony didn’t position either camera as weather-sealed or rugged. Neither features environmental sealing, dustproofing, or shockproofing. Both models lack those robust protections professionals might require outdoors.

Comparing the two in hand, the RX100 VII’s body has the superior heft, grip, and tactile satisfaction. While QX100 is featherweight and minimal, its dependence on a smartphone interface slows down operation and makes intuitive control challenging in bright conditions.

The RX100 VII’s tilting 3-inch touchscreen is bright and responsive, a joy for composing at unusual angles or selfies. Its electronic viewfinder is crisp, with 2360-dot resolution and 0.59x magnification - crucial when shooting in bright sunlight or for precise manual focusing.

The QX100 has no screen or viewfinder and instead relies on the connected phone’s display, which varies in quality and latency depending on your device. Although it supports touch focus via the app, lag and connectivity interruptions were occasional irritants in my hands-on experience.

Lens Performance, Zoom Range, and Macro

Despite both being fixed-lens cameras, the QX100 and RX100 VII differ significantly in zoom coverage and aperture.

• QX100: 28–100mm equivalent, f/1.8–4.9. This 3.6x zoom starts at a bright f/1.8 wide angle, favorable for low light and shallow depth of field. Macro focus down to 5cm is excellent for close-up details.
• RX100 VII: 24–200mm equivalent, f/2.8–4.5. Extends zoom significantly to 8.3x, offering versatile reach for portraits, telephoto wildlife, or tight travel shots, though the widest aperture is slightly slower than the QX100. Macro focus begins at 8cm.

In practice, I found the RX100 VII’s lens to be remarkably versatile - not only capable of portrait bokeh and wide landscapes but also suitable for distant subjects. Its lens optics retain solid sharpness even at telephoto, though diffraction slightly softens corners above f/8.

The QX100’s lens can deliver pleasantly creamy bokeh at f/1.8 but lacks the telephoto reach and more refined zoom mechanics of the RX100 VII. Both deliver optical stabilization, but the RX100 VII’s newer system proved more effective handheld, especially at the extended zoom end.
