The K-01, by contrast, is an entry-level mirrorless camera with an SLR-style body designed for creative flexibility and lens interchangeability.

The TG-1 measures a modest 112x67x30 mm and weighs 230g, eminently pocketable for travel or outdoor use, with physical controls optimized for gloved fingers or wet conditions. Its water-, crush-, and shock-proof casing is engineered for durability over comfort, featuring a grippy but relatively minimalistic interface.

The Pentax K-01, at 122x79x58 mm and 561g, is much bulkier due to its mirrorless interchangeable lens system platform. Its pronounced handgrip and deeper body afford a more traditional SLR feel - better suited for extended handling, manual focus operation, and full-sized lenses, albeit less discreet for street or travel photography.

Control Surfaces and Top-View Design

An in-depth look at the control layouts on both cameras informs their operational priorities and user interfaces.

The Olympus TG-1’s top panel sports a minimal selection: shutter release, power button, and zoom toggle, optimized for simplicity in rugged scenarios. It lacks dedicated dials for exposure mode or manual adjustments - consistent with its fixed lens and point-and-shoot design.

The Pentax K-01 presents a more conventional feature set with dedicated mode dial, exposure compensation dial, and configurable function buttons. This grants the photographer precise, swift control over aperture, shutter, and metering settings, supporting its semi-pro orientation. The K-01’s more complex layout requires acclimation but rewards users with depth of control critical for manual shooting disciplines.

Sensor Size, Technology, and Image Quality Potential

Central to photographic performance is sensor architecture and size, which dictate resolution, dynamic range, noise performance, and depth of field characteristics.

Olympus TG-1 iHS:

• Max ISO: 6400 native
• Antialias filter: Yes

Pentax K-01:

• Sensor type: APS-C CMOS
• Sensor size: 23.7 x 15.7 mm (372.09 mm²)
• Resolution: 16 MP (4928 x 3264 pixels)
• Max ISO: 12800 native, 25600 boosted
• Antialias filter: Yes

The Pentax K-01’s APS-C sensor has over 13x the surface area of the TG-1’s sensor, translating to superior light gathering capacity, better signal-to-noise ratio, and finer detail rendering. This is supported by the higher maximum native ISO and increased dynamic range (DxO Mark scores: Color depth 23.7 vs. TG-1 untested but expected lower; DR 12.9 vs. TG-1 untested).

In practice, the TG-1’s small sensor imposes limitations on image quality, notably in low light, dynamic range, and noise control. It excels in decent light and casual snapshots. The K-01’s sensor allows for large prints, significant cropping latitude, and trades well into professional output realms, particularly in good lighting.

Rear LCD and User Interface for Image Review and Settings

Effective image review and intuitive menu navigation influence efficiency in field and studio.

The TG-1 features a fixed 3.0-inch, 610k-dot screen, adequate for framing and basic menu navigation but limited in resolution for critical focus checks or highlight/shadow evaluation. The fixed screen reduces versatility for creative angles.

The K-01’s 3.0-inch, 921k-dot TFT LCD offers higher resolution, enhancing image playback clarity, histogram view, and detail checks. However, it lacks a viewfinder entirely, which may challenge composition in bright outdoor conditions, an important consideration for many users.

Neither camera utilizes touchscreen input, consistent with their 2012 vintage.
