Lightweight and compact lens
The housing is made of lightweight components, which translates into a very low lens weight of only 146 g. The small size of this glass will certainly appeal to the users of Sony’s mirrorless cameras. It is a great lens for weekend walks and holiday trips.

Fast and accurate autofocus
The lens is equipped with a DSM stepper motor, which makes setting the focus extremely precise, fast and quiet. The accurate autofocus works well during shooting as well as filming.

Focus-by-wire
Manual sharpening mode is supported by Focu-by-wire technology. It facilitates precise sharpening while photographing details and playing with macro photography.

Classic optics
The simple optical design of the lens consists of 8 lenses arranged in 7 groups. One element is optical glass with very low dispersion – responsible for correcting chromatic aberration. The other elements are coated with a nano-coating that reduces glare and flare when working against light.

Technique
Minimum sharpening distance is 45 cm, maximum mapping scale 0.14x. The aperture consisting of 7 leaves closes up to f/16. 49 mm diameter filters can be screwed to the lens.

Software update
The lens is equipped with a micro USB interface, thanks to which we can update its firmware. The latest software (downloadable on the manufacturer’s website) ensures more efficient autofocusing and compatibility with new cameras.
