New 42.5mm lens is available in sharp metallic black and silver, and delivers beautiful defocus to help you add more artistry and creativity into your photography. Offering a 42.5mm middle-telephoto focal distance (35mm camera equivalent: 85mm equivalent to 85mm on a 35mm camera), a high speed f/1.7 aperture, and a versatile focusing distance of 0.31 m, the lens can deliver portraits with a rich stereoscopic effect as well as close-ups with beautiful defocus.

The lens’ POWER O.I.S. system effectively compensates unwanted blur caused by handshake - not only small, fast movements but also large, slow ones - helping you get the results you want, even in low light situations. The POWER O.I.S system, alongside the 240fps Drive AF, delivers stable framing and precise focusing every time.

The 42.5mm portrait lens is available in black and silver from May 2015 for around 399 EUR.
