It outputs 14 megapixels at a maximum native ISO of 1600 (expandable to 6400). This small sensor size means higher noise levels, especially beyond base ISO 100, and limited dynamic range. CCD sensors historically render pleasing color and sharpness but lag behind contemporary CMOS sensors in low-light sensitivity and speed.

• Pentax ist DS2: Utilizes a substantially larger APS-C sized CCD sensor measuring 23.5 x 15.7 mm (368.95 mm²), nearly 13 times the area of the SZ5 sensor, with a 6 MP resolution. Despite the lower pixel count, the larger photosites enable better signal-to-noise ratios, notably improved dynamic range, and superior low-light performance, with native ISO up to 3200.

In laboratory and field testing, the Pentax’s APS-C sensor delivers superior tonal gradation, shadow recovery, and reduced chromatic noise at all comparable ISOs relative to the SZ5. The SZ5’s smaller sensor cannot compete on image quality, but it offers a versatile 10x zoom lens that covers a broad 25-250 mm equivalent range.

Autofocus Systems and Performance

Autofocus (AF) capabilities dictate a camera’s responsiveness in dynamic scenes - critical across sports, wildlife, street, and general photography.

• Panasonic SZ5: Implements 23 contrast-detection AF points with face detection and AF tracking features. Contrast-based AF, while accurate in good light, generally incurs slower focusing speeds and occasional hunting, limiting practical utility in fast-paced shooting. The camera supports continuous AF but lacks touch or selective point AF.

• Pentax ist DS2: Equipped with an 11-point autofocus system featuring phase-detection AF, standard for DSLRs of its era. Phase AF provides faster and more precise focusing compared to contrast detection, especially beneficial for moving subjects. The Pentax system supports selective AF with manual override and focus priority settings, suitable for controlled portraiture or action photography.

Testing in real-world shooting reveals the Pentax ist DS2’s AF system is more adept for tracking moderate motion subjects, such as casual sports or wildlife views. The SZ5’s AF lag and hunting mean it is better suited for static subjects and casual snapshots.
