|Introduction | Olympus best zoom measured on OM-D E-M5 | Olympus M.ZUIKO DIGITAL ED 12-40mm F2.8 PRO lens performance | Olympus M.ZUIKO DIGITAL ED 12-40mm F2.8 vs Panasonic LUMIX G X VARIO 12-35mm / F2.8 ASPH | Olympus M.ZUIKO DIGITAL ED 12-40mm F2.8 PRO vs Sigma 17-50mm F2.8 EX DC OS HSM vs Canon EF-S 17-55mm f/2.8 IS USM | Conclusion|
Introduced alongside the firm’s new top-of-the-range OM-D E-M1 model, this new pro-grade standard zoom is the long awaited rival to Panasonic’s constant aperture G X Vario 12-35mm f2.8 ASPH model. Read on to find out how well it performs.
Announced at the same time as the firm’s new flagship OM-D E-M1 model, this new high-grade wide-angle to short-telephoto zoom is the equivalent to a 24-80mm and boasts a constant f2.8 maximum aperture that will appeal to stills photographers and movie-makers alike. As with other high-grade lenses from Olympus, it has a push/pull focus collar with a declutching mechanism to switch quickly between manual- and auto-focus.
Internally, the new lens has a high-speed linear AF motor for fast, near silent autofocusing, a new dust-, drip- and freeze-proof design and a complex optical construction consisting of 14 elements in 8 groups. The optical design sees liberal use of low dispersion and high-refractive index glass types and both single and double sided aspherical elements. Despite the ambitious spec, the lens remains reasonably compact with a 62mm filter thread, measures 84mm in length and weighs just 382g (13.47 oz) in total. The Olympus M. Zuiko Digital ED 12-40mm f/2.8 PRO is available for pre-order at $999.
