Irix has announced the third lens in its cinema lens line up - the Irix Cine 45mm T1.5. The new manual-focus prime follows joins the Irix Cine 11mm T4.5 and Cine 150mm T3.0 Macro 1:1 lenses in the range.
The lens breaks new ground for the company, as this lens is not an adaptation of one of its existing stills camera lenses (unlike the 11mm and 150mm). The 45mm T1.5 offers a mid-range standard focal length which is said to have been designed with Ultra HD 8K shooting in mind - and therefore ready for the increase in video resolution we are going to see from cinema cameras in the next couple of years.
The Irix Cine 45mm T1.5 is designed to work with full-frame sensors and will be available in Canon EF, Sony E, Micro Four Thirds and Arri PL mounts.
There are 11 optical elements in nine group in this new design. The lens offers a maximum T number of T1.5 which can be reduced to T22, thanks to the rounded nine-bladed iris.
The geared focusing ring rotates 180 degrees with a focus scale (with imperial or metric markings depending on the mount version, we believe); the lens is said to offer practically no focus breathing.
Weighing 1.1kg (2.42lbs) the lens has a 86mm front filter ring - and a standard 95mm front diameter for use with cine accessories. It comes supplied with a detachable tripod foot.
Availability for the 45mm T1.5 lens have yet to be announced, but it is expected to retail for around $1,400 - which is much lower than similar cine lenses from other manufacturers.
