Yet, both appeal to enthusiasts and professionals searching for specialized capabilities in a compact form factor.

This detailed comparison brings together over 15 years of camera testing experience and real-world insights to help you discern which camera suits your photography style and technical needs best. We evaluate these models across physical design, image quality, autofocus performance, usability, and genre-specific applications including landscape, wildlife, macro, and video.

How They Feel in Your Hand: Size and Ergonomics

Ergonomics play a crucial role in how comfortably and efficiently a camera performs in the field. The Olympus TG-5 and Sigma DP1x reveal very different approaches to compactness and handling, reflecting their intended uses.

The Olympus TG-5 measures 113 x 66 x 32 mm and weighs 250 grams. Its compact, tough plastic body incorporates extensive weather sealing to withstand water immersion, dust, shock, crush, and freezing temperatures, making it a true “go-anywhere” tool for adventure photographers. Its shape favors grip and secure one-handed use despite the compact size.

Conversely, the Sigma DP1x is approximately the same width but thicker at 50 mm deep, also weighing 250 grams. The body is a no-frills block-style compact primarily constructed from plastic and metal components but lacking any environmental sealing. It’s built for image quality rather than ruggedness and practicality outdoors. The boxy, minimalistic design feels less ergonomic for extended handheld use compared to more modern compacts.

Functionally, this means the TG-5 excels in outdoor and travel conditions where durability and weather resistance matter, while the DP1x feels more like a thoughtful photographic tool designed for careful composition in stable environments.

Control Layout and Interface: Intuitive or Clunky?

Examining the control experience helps understand daily usability and creative flow, especially during fast-paced shoots.

The Olympus TG-5 features a traditional compact camera layout with well-placed dials and buttons. Despite lacking a touchscreen, its buttons are responsive with illuminated feedback and accessible textured zoom toggle. Its intuitive exposure compensation and aperture priority options cater to enthusiasts wanting manual control without overwhelming complexity.

In contrast, the Sigma DP1x, designed in an era preceding touchscreen ubiquity, opts for simplicity but at the cost of swift adjustment. It lacks any form of autofocus continuous modes or face detection, instead relying on a single AF mode, no AF points array, and minimal exposure automation - intended for photographers comfortable with manual or semi-manual modes. The button arrangement feels dated, and menus navigate slowly due to the older processor and smaller, lower-resolution 2.5-inch display.

As a result, the TG-5 offers quicker, versatile control better suited to varied conditions, while the DP1x demands more deliberate operation, suitable for contemplative shooting.

Sensor Technology and Image Quality: Small Sensor Versus Large APS-C Foveon

At the heart of any camera’s photographic capabilities is the sensor - its size, technology, and processing pipeline determine final image quality, dynamic range, and low-light performance.

• Olympus TG-5: Equipped with a 1/2.3" 12 MP BSI-CMOS sensor, it trades sensor size for compactness and ruggedness. Its TruePic VIII image processor enables 4K video and decent low-light performance up to ISO 12800, but inherent physical limitations result in higher noise levels and reduced dynamic range compared to larger sensors.

• Sigma DP1x: Packs a significant punch with an APS-C sized Foveon X3 CMOS sensor measuring 20.7 x 13.8 mm - a sensor area more than 10 times larger. The Foveon sensor records color information at three different layers, providing increased color fidelity and detail sharpness. However, the camera has a lower pixel count of 5 MP but effectively captures rich detail thanks to the unique sensor. Noise rises faster at higher ISOs though, with a maximum native ISO of just 3200.

The DP1x delivers superior image quality, wide tonal gradation, and excellent color accuracy, especially in controlled lighting and static compositions. In contrast, the TG-5 excels when speed, versatility, and ruggedness are needed, producing good JPGs and RAW files adequate for social media and casual print sizes.

Viewing and Display: Composition and Review

How a photographer interacts with the LCD and viewfinder greatly impacts workflow.

Neither camera features an electronic viewfinder (EVF), placing the entire burden of composition on the rear LCD. The TG-5’s 3-inch 460k-dot fixed screen offers better color accuracy and brightness than the DP1x’s smaller 2.5-inch 230k-dot display, thus aiding precise framing even under strong sunlight.

Moreover, the TG-5 provides live view autofocus aids and a pleasant user interface despite the absence of touchscreen; the DP1x’s UI feels sluggish and less responsive due to older hardware.

For photographers who prefer composing with an EVF, neither camera caters well here - but the TG-5’s display is superior for handheld framing and image review.

Autofocus System: Speed, Accuracy, and Usability

Autofocus (AF) technology defines how reliably and quickly a camera locks focus, especially important in wildlife, sports, and street photography.

• Olympus TG-5 employs contrast-detection AF with 25 focus points, face detection, and tracking autofocus, plus continuous autofocus modes allowing swift subject tracking during bursts - helpful in dynamic environments. Manual focus is also supported.

• Sigma DP1x features only single-shot contrast AF without continuous or tracking functionalities, and lacks AF points or detection systems. Manual focus is present but can be cumbersome.

The TG-5’s AF system is notably superior for action or unpredictable subjects, with quick acquisition and modest accuracy. The DP1x is primarily for slow, methodical shooting where AF speed is not critical, more suited to landscapes or still life.

Burst Shooting and Performance: Capturing the Moment

High-speed continuous shooting matters for wildlife, sports, and street photographers aiming to freeze moments definitively.

• TG-5 offers a remarkable 20 frames per second (fps) burst rate, rare in compacts, enabling precise selection during fast sequences. This speed, paired with AF tracking, supports capturing fleeting wildlife or sports moments.

• DP1x lacks burst shooting capabilities, focusing on single-exposure capture with no continuous mode.

Thus, for action photography, the TG-5 is far more capable.

Photography Genre Suitability: How Each Excels and Lags
