The lens offers large maximum T number of 4.3 which can be reduced to T22, thanks to rounded shape of iris blades.
Functional and highly innovative
When designing the lens mechanical system of 11mm T4.3, we used newly developed technical solutions that have been successfully implemented in the Irix Cine 150mm T3.0 lens. The new Multi Start Thread focusing mechanism allows quiet and precise focusing even under adverse weather conditions such as rain, humidity or extreme temperatures. The focusing geared ring rotates 180 degrees and depending on the lens version, has focusing scale with metric or Metric units.
Thanks to the another innovative solution like adaptive ring, the IRIX 11mm f4 Blackstone Lens for Nikon F ensures great ergonomics of operation both by hand and with follow focus mechanism. Moreover, despite of the very short optical system layout, geared rings of focus and aperture were placed at the same height as in other Irix Cine lenses – all for better ergonomics and more intuitive use.
The exceptional functionality and innovative solutions are a distinctive feature of all Irix products. The same applies to the IRIX 11mm f4 Blackstone Lens for Nikon F, whose extremely compact design (weights 1,1 kg) has been also equipped with an innovative Magnetic Mount System for accessories.
