Sony RX100 IV vs Sony W310: A Deep Dive Into Compact Cameras Across a Decade

Choosing a camera is a pivotal step in any photographer’s journey. Whether you’re a seasoned pro looking for a portable pocket powerhouse or a casual enthusiast eager to take better snapshots on vacation, understanding how cameras compare in real-world use is key. Today, we'll explore two Sony compact cameras from different generations and categories: the Sony RX100 IV, a large sensor compact announced in 2015, and the Sony W310, an ultracompact from 2010.

This comprehensive 2500-word comparison will help you understand the technological leap between these models, their suitability for various photography disciplines, and ultimately, which one aligns best with your creative needs and budget.

First Impressions: Size, Build, and Handling

The physical design and ergonomics of a camera heavily influence user experience, especially for compact models meant to accompany you everywhere.

The RX100 IV feels more like a serious camera in your hand, with a robust magnesium alloy construction and an ergonomic grip that facilitates stable shooting over extended periods. Its tilting screen and integrated high-res electronic viewfinder also support photographic creativity from multiple angles and bright environments.

In contrast, the W310 is delightfully pocketable and ultra-light but with compromises - the slim body lacks a dedicated grip and its fixed basic LCD is smaller and less sharp. Without a viewfinder, deriving composition must rely solely on the LCD, challenging in bright sunlight.

User Insight: If portability trumps all, the W310 is unbeatable for snapshots and casual travel. For photographers ready to step up in control and handling, the RX100 IV feels like a natural extension of the hand.

Sensor Technology and Image Quality: The Heart of the Matter

Arguably the most influential factor on image quality is the sensor size and technology. Here, the RX100 IV moves far ahead of the W310.

The RX100 IV’s 1-inch BSI-CMOS sensor boasts over four times the surface area of the W310’s 1/2.3-inch CCD. This translates into significantly better light gathering ability, dynamic range, and low-light performance - paramount factors when shooting challenging lighting conditions or demanding subjects.

Technically, the RX100 IV achieves a DxOmark overall score of 70, showcasing excellent color depth (22.9 bits), dynamic range (12.6 EV), and low-light sensitivity (ISO equivalent 562). The W310, an entry-level compact with a smaller CCD sensor, lacks raw output capability and lags behind on these counts.

Real-World Implication: The larger sensor and advanced image processor (Bionz X) in RX100 IV mean it excels in capturing natural skin tones, fine details in landscapes, and cleaner high ISO images. The W310 works sufficiently for casual prints and social media images but will show noise and less detail when scrutinized.

Lens and Zoom: Balancing Reach and Brightness

Great sensors need equally capable optics to maximize image quality.

The RX100 IV's lens aperture starts impressively bright at f/1.8 on the wide end, ideal for shallow depth of field portraits and low-light scenarios. This aperture gradually narrows to f/2.8 at telephoto end but remains relatively fast, supporting consistent exposures across the zoom range. With a 24-70mm equivalent focal length, it covers wide-angle to short telephoto, fitting for portraits, landscapes, and street photography.

Conversely, the W310 features a longer zoom range (28-112mm equivalent) but at relatively slow apertures (f/3.0-f/5.8). This compromises low-light ability and bokeh capacity but offers greater reach for casual zoom needs.

Practical takeaway: For flattering portraits with subject separation and creative background blur, the RX100 IV’s bright lens offers a distinct advantage. The W310 favors versatility and convenience over aperture speed.

Autofocus, Speed, and Usability in Action

A camera’s autofocus system and shooting speed are vital for capturing fleeting moments. Here, the RX100 IV delivers professional-grade performance.

With phase detection autofocus absent in both models, the RX100 IV leverages advanced contrast-detection with impressive responsiveness and accuracy. Real-world testing reflects smooth, reliable AF tracking on moving subjects, augmented by face detection and various AF area modes. Its 16 frames per second high-speed burst comfortably handles action, wildlife, and sports photography requiring rapid-fire capable cameras.

The W310's AF system is basic, limited to 9 points and only single AF operation. Its slow continuous shooting rate of 1fps limits the ability to capture fast action sequences.

User Impact: The RX100 IV is suitable for photographers who demand reliable autofocus performance to shoot unpredictable subjects - from kids to wildlife or sports. The W310 is best reserved for posed or static scenes.

Creative Features and Interface Advances

The RX100 IV's controls and connectivity cater to both amateurs aiming to learn and pros seeking quick access to critical settings.

The RX100 IV impresses with an electronic viewfinder for bright-light composition, extensive manual controls, and tilting LCD facilitating low/high angle shots and selfies. Wireless features such as Wi-Fi and NFC enable instant sharing and remote control from smartphones - a modern convenience absent in the W310.

In contrast, the W310 limits user input to simple point-and-shoot modes, fixed LCD, and basic flash control. Its lack of wireless options and viewfinder demonstrates its beginner/snapshot class design.

Practical note: Photographers craving direct control over exposure and framing will favor the RX100 IV’s interface, while casual shooters appreciate the no-fuss simplicity of the W310.

Comprehensive Photography Use Case Review

How do these cameras stand up to real-world shooting genres? We analyzed their strengths for popular disciplines.

Examining sample images side-by-side, the difference is palpable. The RX100 IV delivers vibrant, sharp images with rich contrast and smooth gradients. The W310 images tend to be softer, with less dynamic range and visible noise in shadows or low light.

Battery Life, Storage, and Connectivity Realities

Battery life and storage options impact your shooting endurance and workflow convenience.

The RX100 IV’s battery life is average owing to its demanding large sensor and EVF use; consider carrying a spare NP-BX1 battery for long shoots. Wireless options accelerate file transfer in the field, essential for fast content delivery.

In contrast, the W310 with its lack of wireless and smaller size likely offers modest battery endurance, and you’ll rely on USB for offloading files - a slower process.

Value and Price-to-Performance Overview

The RX100 IV holds excellent value for enthusiasts or professionals seeking a pocketable camera to supplement their main gear or serve as an all-in-one travel companion. Its advanced sensor, lens, and video features justify the higher price.

Meanwhile, the W310’s low cost and ultra-compact size cater to absolute beginners or users who prioritize simplicity and affordability over performance.
