Weighing just over 2kg, the M.Zuiko 150-600mm f/5.0-6.3 IS is a super-telephoto lens that’s equivalent to 300-1200mm in full-frame terms. As it’s compatible with teleconverters such as the Olympus MC-20, this latest M.Zuiko optic can have a maximum effective reach of 2400mm. Also featured on this new lens is OM’s Sync-IS technology, which combines the optical stabilisation of the lens with the in-body image stabilisation of the OM-1 Mark II, OM-1 and OM-5 (plus the E-M1 and E-M5) camera bodies. Used alone, the lens delivers up to six stops of image stabilisation, which is amplified to seven on compatible bodies. The optical path features 25 elements in 15 groups, including four Super ED (extra-low dispersion) lenses and one high-definition lens. Its close-focusing capabilities are also impressive: as close as 0.56m at the wide end and 2.8m at the long end. explore.omsystem.com; £2,400/$2,700
