Fujifilm has built a Quad Linear Motor into its new XF 90mm f/2R LM WR lens, saying the move will boost AF speed to 0.14sec.

The fast-aperture 11-elements-in-8-group Fuji 90mm prime lens is designed to deliver the 35mm viewing angle of a 137mm optic.

A Fuji spokesman told AP that the 90mm f/2 is the ‘sharpest’ lens in the firm’s line-up and will produce a ‘beautiful bokeh’.

Claimed to be weather and dust-resistant, the newcomer features a minimum focus distance of 60cm and the ability to work in temperatures down to -10° C, according to Fuji.

The seven–blade diaphragm lens incorporates three extra low-dispersion elements to help reduce chromatic aberration.

Billed as lightweight and compact, the 540g lens measures 75 x 105mm and will cost £699 when it goes on sale in late July.
