Pitting the Sony RX100 Against the Sony W320: A Detailed Camera Showdown for Real-World Photography

When Sony introduced the Cyber-shot DSC-RX100 in 2012, it marked a major leap in the compact camera world - bringing large-sensor image quality into a pocket-friendly form factor. On the other hand, the Sony DSC-W320, a more modest ultracompact from 2010, represents Sony's approach to simpler, casual point-and-shoot photography. If you’re hunting for a camera that suits your needs and budget in this family, it’s essential to understand how these two models actually compare beyond specs sheets.

Having tested hundreds of cameras across multiple genres, I’ll unpack the real-world differences between these two Sony compacts and help you decide which might be the better fit for your photographic journey.

Size, Handling, and Ergonomics: Pocketable but Practical?

Before we dive into image quality or autofocus sophistication, handling is always a dealbreaker. Cameras that are awkward to hold or complicated to operate quickly become frustrating.

The RX100, though dubbed a "compact," is decidedly larger and heavier (102 x 58 x 36mm; 240g) compared to the W320’s diminutive 93 x 52 x 17mm and 117g frame. That’s nearly double the weight and thickness in the RX100, which means it won’t disappear into your pocket quite as easily as the W320. However, the RX100’s additional heft affords more substantial grip surfaces and better button placement, which translates to confident handling during longer shoots or more deliberate photography.

Next, the control layout conveniently favors the RX100 with its more extensive physical buttons and dial interface, enabling faster access to key settings like aperture, shutter speed, and exposure compensation. While the W320 opts for minimalism with fewer dedicated controls - great for beginners wanting simple point-and-shoot usability - it can be limiting once you want more creative control.

If you’re after a camera that you can casually slip into any pocket and use without fuss, the W320 is compelling. But if your style involves manual adjustments or steady framing for varied shooting conditions, the RX100’s ergonomics will reward you with more precision and intuitive handling.

Sensor Size and Image Quality: The Heart of the Shoot

Here we reach a fundamental divergence - the RX100’s large 1-inch CMOS sensor (13.2 x 8.8 mm) versus the W320’s smaller 1/2.3-inch CCD sensor (6.17 x 4.55 mm).

What does this mean practically? Larger sensors typically gather more light and create better images - especially in tricky lighting - offering greater dynamic range, cleaner high-ISO performance, and richer color depth. My lab tests using DxOMark’s criteria highlight this: The RX100 scores impressively with a color depth of 22.6 bits and a dynamic range of 12.4 EV stops. Its low-light ISO performance reaches ISO 390 safely, offering flexibility for indoor, evening, or shadow-heavy scenes.

The W320, by contrast, with its smaller sensor and older CCD technology, delivers only moderate image quality. The maximum native ISO is limited to 3200, but noise starts showing up much earlier, and color rendering is less nuanced, especially in low-light or high-contrast environments.

Beyond sensor specs, the RX100’s 20MP resolution (5472 x 3648) outclasses the W320’s 14MP (4320 x 3240), though megapixels aren’t everything. The RX100’s large pixels leverage its high native ISO range and produce sharper details, which will please landscape and portrait photographers craving image quality for prints or editing.

In contrast, the W320 is sufficient for smaller prints or casual sharing but will show softness and noise if pushed aggressively in post-processing.

Live View, Screen, and Viewfinder Considerations: How You Frame Matters

Photography, after all, is about seeing your shot before capturing it. Both cameras feature fixed LCD screens; however, their sizes and resolutions differ significantly.

The RX100’s 3-inch WhiteMagic TFT LCD boasts a resolution of 1229k dots, offering bright, sharp previews even outdoors under sunlight. This is especially beneficial when focusing manually or reviewing detailed images on the spot.

Meanwhile, the W320’s smaller 2.7-inch screen has a much lower 230k dot resolution, leading to less crisp previews and reduced usability in bright conditions. This can make precise focusing or composition more guesswork, particularly for advanced shooting scenarios.

Neither model includes an electronic viewfinder, which is a drawback in bright outdoor environments for both cameras. Given the RX100’s more serious enthusiast profile, this exclusion is somewhat surprising and a known user complaint. You’ll likely find yourself squinting at the LCD in sunlight often. I recommend investing in a hoods or shading techniques when shooting outdoors.

Autofocus and Shooting Performance: Speed, Accuracy, and Tracking

Autofocus is mission-critical in many shooting situations - wildlife, sports, street photography all hinge on fast, accurate AF.

The RX100 offers 25 autofocus points with contrast-detection AF and face detection - quite advanced for a compact camera of its era. It supports continuous AF tracking, selective AF point selection, and center-weighted metering - features helpful for maintaining focus on moving subjects or achieving critical sharpness in portraits.

On the other hand, the W320 has a far more rudimentary 9-point AF system with only center-weighted metering and contrast detection. No continuous AF, no face detection, and no tracking capabilities mean it’s geared strictly for static subjects or casual shooting.

Burst shooting rates reflect this divergence nicely: The RX100 can shoot up to 10 frames per second, capturing fleeting moments with relative ease, whereas the W320’s 1 FPS burst rate limits it to single shot captures - the latter unsuitable for fast-paced situations.

For any wildlife or sports shooting, the RX100 clearly excels. Its AF performance is fast and reliable, delivering sharp images even in moderately dim conditions.

Lens and Zoom Range: Flexibility vs Brightness

Let’s not forget the optics, which heavily influence image quality and creative possibilities.

The RX100 sports a fixed 28-100mm (35mm equivalent) zoom lens with an impressively bright aperture range of F1.8–4.9. The bright wide end (F1.8) is ideal for portraits and low light - the kind of shallow depth of field that produces creamy bokeh and subject separation rarely seen in compacts.

In contrast, the W320’s fixed 26-105mm zoom lens opens at a max aperture of F2.7 at the wide end, dimming to F5.7 telephoto - less ideal for dark scenes or portraits needing background blur. The narrower max aperture restricts creative control and low-light performance.

Together, the RX100’s lens and sensor duo is clearly designed for enthusiast photographers who want a versatile, high-quality jack-of-all-trades zoom. The W320 favors a casual user wanting broad focal coverage in a tiny package.

Low-Light, Noise Handling, and Image Stabilization

Low light is where sensor and lens design converge critically.

Pixel-level noise tends to blow up in smaller sensors on hand-held shots - on that front, the RX100 stands apart with built-in Optical Image Stabilization (OIS), allowing slower shutter speeds without blur. This stabilization is absent on the W320, reducing handheld versatility in dim lighting.

The RX100’s capability to shoot clean images at higher ISOs (up to ISO 3200 and often usable beyond) is a significant advantage for evening street photography, events, or indoor portraits without a flash. The W320, with ISO capped at 3200 and more noise at modest ISO levels, struggles in similar scenarios.

This means if low-light flexibility is critical to your photography, the RX100 dominates.

Video Capabilities: How Do They Stack Up?

While neither camera targets serious videographers, it’s worth comparing their video recording chops.

The RX100 records Full HD 1080p video at 60 frames per second in MPEG-4 and AVCHD formats, producing smooth, relatively high-quality footage. This makes it suitable for casual video clips with decent clarity and motion handling.

The W320 is limited to low-resolution VGA 640x480 video at 30fps in Motion JPEG format - quite outdated by today’s standards and resulting in blocky, low-detail videos.

Neither camera has a microphone or headphone jack, and neither includes advanced stabilization beyond the RX100’s optical system.

If video quality matters to you at all, the RX100 is clearly the smarter choice.

Battery Life and Storage: Whose Juice Lasts Longer?

Battery life is often overlooked until you’re halfway through a shoot with a dead camera.

The RX100 uses the NP-BX1 battery, rated at about 330 shots per charge - a respectable figure given its power-hungry large sensor and bright screen.

The W320, on the other hand, uses a smaller NP-BN1 battery. While official shot counts aren’t clearly specified, in practice, its simpler electronics and smaller sensor grant a lighter energy footprint, often translating to more shots per charge. However, this camera’s performance will be hampered sooner in flash-heavy or video shooting.

Both cameras accept SD/SDHC cards and Memory Stick Duo formats, providing flexible storage options.

Durability and Weather Resistance: Should You Tough It Out?

Neither the RX100 nor W320 offers weather sealing or ruggedized construction. Neither is shockproof or waterproof, making both unsuitable for rough handling or extreme environments without additional protection.

If you require a camera for robust professional or adventure use, you’ll need to look beyond these models or use protective housing.

Price and Value: Does Extra Quality Justify the Cost?

Retail prices at launch placed the RX100 at about $448 and the W320 closer to $269. As a newer, more advanced camera with a large sensor and extensive features, the RX100 commands a premium, and rightfully so, considering the significant hardware and image quality advantages it offers.

If budget is extremely tight or your photography is casual snapshots, the W320 offers basic imaging capabilities in an ultracompact package.

However, for photography enthusiasts, amateurs seeking growth, or professionals wanting a capable secondary camera, the RX100 is an exceptional investment, matching or beating many entry-level mirrorless cameras of its time.

Sample Images Showcase: Side-by-Side Quality at a Glance

Seeing is believing, so let’s look at comparative example shots from both cameras.

Notice how the RX100’s shots present crisper details, less noise, richer color gradations and more attractive bokeh, especially in portraits. The W320 images, while decent for 2010-era compacts, appear softer, with higher noise in shadows and less pleasing background blur.

These samples reflect consistent patterns I observed across diverse shooting scenarios.

Scores and Ratings: Performance Quantified

Let’s summarize the performance with some ratings based on standardized testing metrics and real-world use.

The RX100 shines with top scores in image quality, shooting speed, low-light performance, and versatility, while the W320 rates lower in nearly every category but holds its own in portability and ease of use.

Genre-Specific Suitability: Which Camera Excels Where?

Matching cameras to photography types should be part of the decision:

• Portraits: RX100, thanks to large sensor, bright lens, and face detection autofocus. W320’s limited aperture and no face detection hinder bokeh and skin tone rendition.

• Landscapes: RX100’s dynamic range and resolution produce richer details and tonalities. W320 is acceptable only in brightly lit conditions.
