IRIX has announced a new full-frame telephoto macro lens, the 150mm F2.8 Macro 1:1.

The 1:1 reproduction lens will be available for Nikon F, Canon EF and Pentax K mounts and claims to have 'close to zero distortion,' according to IRIX — just 0.1 percent, thanks to the optical construction consisting of twelve elements in nine groups.

IRIX touts the telephoto focal length as a benefit noting 'the possibility of being able to move away from the photographed object [...] makes the operation more convenient than using lenses with a shorter focal length. No shadows are cast on the object and it is also possible to use lamps dedicated to this type of photography.' Its internal focusing mechanism means the lens won't shrink or expand when focusing.

The lens features select weather-sealing at various areas on the lens and has a rubberized focus grip with 270-degrees of rotation. There's also Focus Lock and a removable Arca Swiss lens collar for easy shooting on a tripod.

The construction of the lens features IRIX's new 'Dragonfly finish.' In Irix's own words, 'the aluminium frame has been enclosed in an external structure made of aluminium-magnesium alloys and composite elements. The combination of Firefly and Blackstone features gave the lens lightness and solidity while maintaining high mechanical strength and resistance in difficult weather conditions.'
