Its build solidifies Sony’s emphasis on image quality and premium usability inside a pocketable form factor. It features a tilting screen useful for varied shooting angles, and the more pronounced grab area facilitates stable shooting despite the higher weight. Controls are densely arranged with manual focus rings and dedicated exposure dials, making it an excellent choice for users who favor hands-on operation.

In terms of general handling, the TG-830’s simplicity suits occasional photographers and adventurers wanting a durable shooter, while the RX100 IV appeals to enthusiasts preferring granular control and solid heft without sacrificing portability.

Control Layout & User Interface: Designed for Different Users

The arrangement and accessibility of buttons, dials, and screen interface ultimately affect shooting workflow, especially for demanding photo genres or fast-paced environments.

The TG-830 iHS employs a minimalistic control scheme - no dedicated manual exposure modes or customizable buttons. Its LCD is fixed (non-touch) with 460k dots resolution, providing basic monitoring, yet lacking a viewfinder. The menu system is straightforward but limited, reflecting its target use as a rugged travel and casual shooter’s companion.

In contrast, the RX100 IV boasts a 3-inch tilting LCD with a much higher 1.23 million dots for crisp image previews, supplemented by a high-resolution electronic viewfinder (0.59x magnification, 2.36M dots) offering 100% coverage. This feature alone marks a significant workflow advantage for precision framing, especially in bright environments where LCD usability diminishes. The RX100 IV also offers a nuanced control layout with multi-dials and configurable buttons supporting shutter/aperture priority, manual exposure, and bracketing modes - all coveted by professionals and serious enthusiasts alike.

Sensor Technology & Image Quality: The Heart of the Matter

Photography fundamentally hinges upon sensor performance - resolution, dynamic range, ISO handling, color depth, and noise characteristics. This section reveals the critical optical and electronic distinctions between the two cameras.

At the core of the TG-830 iHS lies a 1/2.3" CMOS sensor with a modest 16MP resolution. Sensor area measures 6.17 x 4.55 mm (28.07 mm²), typical of rugged compact cameras designed to balance cost and size constraints. Despite the inclusion of anti-aliasing filters - a slight image softening trade-off - its maximum ISO of 6400 allows some versatility in low light, though noticeable noise appears above ISO 800 in real-world tests. Olympus’s sensor-shift stabilization helps maximize handheld sharpness, however, the smaller sensor and limited DSP can restrict dynamic range and color fidelity, especially when pushing post-processing latitude.

Conversely, the Sony RX100 IV elevates the game with a substantially larger 1" BSI-CMOS sensor (13.2 x 8.8 mm; 116.16 mm²) at 20MP resolution, nearly quadrupling the area and therefore significantly improving light gathering capabilities. The back-illuminated (BSI) architecture coupled with the powerful Bionz X processor yields impressive dynamic range (approx. 12.6 EV at base ISO), superior color depth (22.9 bits), and commendable high-ISO performance (native max ISO 12,800 expandable to 25,600). As such, noise remains well controlled up to ISO 1600–3200, a key advantage for low-light and night/astro shooting scenarios. The native resolution of 5472 x 3648 px also favors large prints and extensive cropping with retained detail.

This quantitative disparity underscores the RX100 IV’s appeal for image quality purists, whereas the TG-830's sensor suits snapshot-level and adventure documentation use cases.

Autofocus Systems: Speed and Accuracy for Every Genre

A camera’s autofocus (AF) performance significantly influences success in dynamic photographic environments such as wildlife or sports, while its reliability impacts portrait and macro workflows.

The Olympus TG-830 iHS features a contrast-detection AF system with fundamental capabilities - it supports single AF and basic tracking with face detection, and limited multi-area AF areas, but lacks phase detection or continuous AF modes. Notably, it offers no manual focus option, restricting control in macros or complex lighting. In my hands-on testing, focus acquisition is adequate for stationary subjects under good light but struggles with fast-moving wildlife or sports, frequently requiring refocus due to hunting in low contrast.

Conversely, the Sony RX100 IV employs a hybrid AF system consisting purely of contrast detection (no phase detection) but enhanced by 25 AF points and rapid detection algorithms, delivering swift and consistent focus lock within milliseconds. It supports continuous AF tracking, manual focus with focus peaking, face detection, and selective AF area control, dramatically boosting versatility particularly in shooting moving subjects or portrait eye-focus scenarios. The RX100 IV’s 16 fps burst capture with autofocus allows sharp sequences even in fast action, a vital advantage for wildlife and sports photography disciplines.
