Both cameras employ a 1/2.3-inch CCD sensor measuring 6.17 x 4.55 mm with an identical effective imaging area of 28.07 mm², adhering to industry standards for compact cameras.

The TG-610 boasts a 14-megapixel resolution, marginally higher than the T90’s 12 megapixels. However, real-world image quality gains from increased resolution at this sensor size tend to be nuanced, with trade-offs in noise if higher ISO or low-light conditions challenge the sensor.

Dynamic Range and ISO Performance

While neither model features official DxO Mark testing, in practical use the TG-610 shows somewhat improved dynamic range and better noise control at native ISOs (80-1600), likely due to its later-generation TruePic III+ image processor. The Sony limits ISO to a maximum of 3200 but with significant noise intrusion at these levels; however, the Sony’s maximal shutter speed of 1600 ms allows longer exposures for low light when stabilized.

Image Processing and Color Reproduction

Olympus’s TruePic III+ processor facilitates more accurate color rendering and contrast rendition under varied lighting, which benefits portrait skin tones and natural landscapes alike. Sony’s processing tends to render images with a cooler balance and modest saturation, matching the Cyber-shot’s general consumer focus but offering less flexibility for post-processing without raw capture support (unsupported on either).

Autofocus and Shooting Performance: Speed and Accuracy Under Pressure

In-field camera responsiveness can make or break moments, especially for action, wildlife, or travel photography.

Autofocus Systems Compared

The TG-610 features a contrast-detection autofocus with face and eye-detection capabilities, improving subject tracking accuracy in typical shooting scenarios. Although the exact number of AF points is not specified, Olympus’s multi-area AF combined with face detection enhances portrait and casual capture.

Sony’s T90 has a 9-point contrast-detection AF system but lacks face detection, limiting its tracking efficacy particularly for portraits or moving subjects.

Continuous Shooting and Shutter Speed

Burst rates remain modest on both models, with the T90 achieving 2 fps and the TG-610 limited to a single frame per second, resulting in missed opportunities for fast action photographers.

The shutter speed range differs, with the Olympus offering 4 s to 1/2000 s and the Sony supporting 1 s to 1/1600 s, favoring the TG-610 for action freeze and longer exposures.

Durability and Environmental Resistance: Built for Different Lifestyles

For photographers venturing into challenging or unpredictable conditions, solid environmental sealing is paramount.

Weatherproofing and Shock Resistance

The Olympus TG-610 is explicitly designed as a rugged camera: waterproof to 3 meters, freezeproof down to -10°C, dustproof, and shockproof from up to 1.5 meters. This makes it ideal for outdoor enthusiasts, adventure photographers, or users who need a durable, worry-free companion.

In brittle contrast, the Sony T90 lacks any form of environmental sealing. Its ultra-slim body prioritizes portability over protection, thereby requiring more caution in inclement weather or demanding environments.
