Andy Westlake tests the Tamron 14-150mm f/3.5-5.8 Di III
Tamron 14-150mm f/3.5-5.8 Di III review: Features
Comprising 17 elements in 13 groups and including one low-dispersion glass element, two anomalous dispersion glass elements, two glass-moulded aspherical elements and one hybrid aspherical element, the 14-150mm has the most complex optical design among Micro Four Thirds superzoom lenses. In principle, this should help reduce the optical aberrations to which lenses with such an ambitious zoom range tend to be prone.
Despite all this glass, the 14-150mm is surprisingly compact, with a barrel diameter of 63.5mm and a length of 80.4mm from the mount to the front of the non-rotating 52mm filter thread. In context, it’s smaller than Olympus’s budget M.Zuiko Digital 40-150mm f/4-5.6 telezoom and barely larger than 18-55mm kit zooms for APS-C DSLRs. At 285g it’s not especially heavy, either.
I’m pleased to say the lens is supplied with a bayonet-fitting petal-type plastic lens hood. Even better, it reverses neatly when not in use, fitting closely around the barrel. Packing up small is a real asset for this kind of travel lens.
