Tamron will next month release a 14-150mm zoom for micro four thirds cameras, priced u00a3389.99.

The 14-150mm f/3.5-5.8 Di III, the development of which was first announced in January 2013, features a stepping motor, optimised to provide a ‘seamless, fluid autofocusing action when shooting video’.

The 17-elements-in-13-groups, 285g lens is available in black and silver colour options. It delivers a focal length of 28-300mm in 35mm terms.

The lens includes one low-dispersion element, two anomalous-dispersion elements, two aspherical elements, plus a hybrid aspherical element, to help reduce aberrations.
