The S6100 provides a 7x optical zoom range equivalent to 28–196 mm with an aperture of f/3.7–5.6. This extensive focal coverage caters to casual photography, from wide-angle landscapes to reasonable telephoto shots. However, the relatively slow maximum aperture can impose limitations in low light and reduces subject-isolating bokeh capabilities, particularly at long focal lengths.

The TG-3 is configured with a shorter zoom range of 25–100 mm (4x zoom) but benefits from a substantially faster maximum aperture of f/2.0 at the wide end, extending to f/4.9 at telephoto. This bright lens markedly enhances low-light and macro capabilities, minimizing reliance on high ISO and enabling shallower depth of field control than typical compacts.

The TG-3’s macro focus distance of 1 cm outperforms the S6100’s 3 cm minimum, enabling more detailed close-ups and facilitating focus stacking and bracketing functions for extended depth-of-field control - a notable advantage in dedicated macro and product photography workflows.

Autofocus System: Speed, Accuracy, and Tracking for Dynamic Scenes

The Nikon S6100 features a 9-point contrast-detection autofocus system with face detection and tracking capabilities. However, its AF speed is notably sluggish, and continuous autofocus for moving subjects is unsupported. This impacts applications like sports, wildlife, and street photography where rapid AF response and tracking are paramount.

In comparison, the Olympus TG-3 integrates more advanced contrast-detection autofocus with continuous AF and face detection/tracking. Its AF performance is markedly faster and more reliable in dynamic shooting scenarios, as confirmed in field tests involving moderate-motion subjects.

Both cameras lack phase-detection autofocus and animal eye AF - a professional-level feature set reserved for interchangeable lens systems. Nonetheless, TG-3's responsive AF and focus bracketing/stacking expand its suitability for macro and action photography within the fixed-lens compact format.

Burst Shooting and Shutter Performance: Capturing the Decisive Moment

Continuous shooting speed represents a practical parameter in capturing fast action. The Nikon S6100 offers a limited 1 fps burst rate, insufficient for sports or wildlife action sequences, and susceptible to buffer limitations over extended sequences.

The Olympus TG-3 significantly improves upon this with a burst rate of 5 fps, affording more frames to increase the probability of success in timing-critical shots. While modest compared to dedicated DSLR or mirrorless cameras, TG-3’s framing cadence is acceptable for entry-level sports and moderately fast wildlife photography.

Maximum shutter speeds for both cameras max out at 1/2000s - adequate for freezing motion in most daylight conditions but constrained when attempting ultra-fast shutter control or shallow depth of field in bright environments.
