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. '
