The focal length of this lens is equivalent to 27.5-83.0mm in the 35mm format. This versatile zoom range allows for a variety of photographic applications, from wide-angle to telephoto.

The maximum variable aperture of the lens is f2.8-4.5, providing a bright and fast optical performance. This wide aperture range is particularly useful in low-light conditions, enabling the photographer to achieve a shallow depth of field and capture stunning, well-exposed images.

To minimize chromatic aberrations throughout the zoom range, the lens features four extra-low dispersion (ED) aspherical lens elements. These specialized optical elements effectively correct color fringing, ensuring high-quality, sharp images with minimal distortion.

The lens shutter is equipped with 5 aperture blades and is capable of syncing with the built-in flash of the Q camera at shutter speeds up to 1/2000 second. This fast sync speed allows for the use of fill-flash in bright conditions, giving the photographer greater creative control over their images.

Furthermore, the lens is equipped with a neutral density (ND) filter, which enables open-aperture photography in bright settings. This feature is particularly useful for achieving a shallow depth of field, even in well-lit environments, allowing the photographer to maintain creative control over the image.

Overall, this lens offers a versatile focal length range, fast and variable aperture, advanced optical correction, and specialized features that cater to the needs of discerning photographers. The combination of these capabilities makes this lens a valuable asset in the pursuit of exceptional image quality.
