Key Features

• HLA (High-response Linear Actuator) for fast, quiet autofocus and subject tracking.​

• Up to 6 stops of optical stabilization (OS2 algorithm) for handheld sharpness.​

• 1:2 macro magnification at 70mm, with close-focusing capabilities across the range.

• Dust- and splash-resistant build, plus a water/oil-repellent front coating.​

• Compact at 4.8 inches long and 1.4 lb, with a zoom lock.​

Performance

Image quality is strong centrally with good sharpness, aberration control via 1 FLD, 4 SLD, and 4 aspherical elements, and minimal flare.
Peripheral sharpness and long-end performance sacrifice some detail due to the extreme range, though it’s competitive for superzooms.
Autofocus excels in speed but trails dedicated telephotos in tracking.

Use Cases

Perfect as a single-lens travel solution for landscapes (wide end), wildlife (telephoto), and close-ups.
Narrow max aperture (f/3.5-6.7) limits low-light work compared to primes.
