It's a system of 10 lenses arranged in 8 groups.
They include one aspherical (AS) lens and two lenses made of extra low dispersion glass (ED). The lens surfaces are covered with multi-layered UMC anti-reflective coatings enhancing light transmission and maximising contrast.
The lens will be available for £279 in early July.
