Additionally, the HX90V includes a pop-up electronic viewfinder with 638-dot resolution, 100% coverage, and 0.5x magnification equivalence, vastly improving compositional accuracy under strong sunlight or dynamic shooting scenarios.

The presence of an EVF on the Sony camera is a significant advantage for photographers who require rapid framing precision and stable handling during telephoto use.

Lens and Zoom Capabilities

One of the most striking differences is in lens versatility and focal range.

• Canon A3100 IS: Fixed 35–140 mm equivalent lens (4× optical zoom) with an aperture ranging from f/2.7 at wide-angle to f/5.6 at telephoto. This range is modest, suitable mainly for casual snapshots, portraits, and close-ups but limited for distant subjects.

• Sony HX90V: Offers a remarkably extensive 24–720 mm equivalent zoom (30× optical zoom) with f/3.5–6.4 aperture. This extreme reach is unique in small sensor type compacts, supporting wide landscapes and far-removed subjects such as wildlife or distant architecture without additional lenses.

The trade-off with superzoom lenses includes slower maximum apertures at telephoto extremes and potential compromises in image sharpness due to lens complexity. However, Sony’s optical image stabilization system partially counteracts camera shake, a critical factor when shooting at 720 mm equivalent.

Autofocus System and Shooting Performance

Autofocus (AF) speed, accuracy, and continuous tracking capabilities impact suitability for various photography domains, from portraits to sports.

• Canon A3100 IS: Implements a contrast-detection-only AF system with nine points. AF speed is moderate and limited to single AF mode (no continuous or tracking). Without face or eye detection, acquiring precise focus on moving or complex subjects can be challenging. This restricts the Canon mainly to static compositions or predictable scenes.

• Sony HX90V: Employs an enhanced contrast-detection AF augmented by the Bionz X processor, enabling fast single AF, continuous AF, and tracking modes. It supports face detection autofocus but lacks specialized animal or eye AF. However, continuous and tracking AF improve success rates when capturing moving subjects, relevant for casual wildlife or street photography.

Additionally, the HX90V sustains a continuous shooting speed up to 10 frames per second (fps), facilitating capture of action sequences. Canon’s A3100 IS is limited to a single fps rate, severely constraining candid or sports shooting.
