Cine lens manufacturer Irix has announced the impending arrival of the Irix Cine 45mm T1.5, its latest full-frame cinema lens.

This new lens marks the third full-frame cinema lens Irix has made specifically for shooting at up to 8K resolution. Irix says the 45mm T1.5 is ‘based on a completely new [11 elements in 9 groups] optical design which includes four elements made of high refraction glass, one extra-low dispersion lens and one aspherical lens’ and delivers ‘ultra-low’ 0.5-percent distortion.

The nine-blade aperture diaphragm ranges from T1.5 to T22 and the lens features ‘practically no focus breathing,’ according to Irix. Other features include a 95mm front filter thread on the housing of the lens, another 86mm built-in filter thread and a reversible lens hood that’s attached via magnets, which Irix teases will work with ‘future accessories.’

The gears are standardized 0.8 pitch mod cine gears and the lens, which is constructed of a magnesium-aluminum alloy is sealed. Irix doesn’t specify what the lens should be able to handle, other than saying it’s ‘prepared for all weather conditions.’

The Irix Cine 45mm T1.5 will be available in Canon EF, Sony E, MFT and Arri PL mounts. Pricing and availability ‘will be announced soon.’

Irix Cine 45mm T1.5 — into the art of cinematography

Irix expands its offer of cinematographic lenses with the new full-frame 45mm T1.5.

Irix, the manufacturer of high-class optics, expands its Cine line by introducing the new 45mm T1.5 lens. This new model is the third full frame cinematographic lens designed for shooting with Ultra HD 8K cinema cameras. The Irix 45mm T1.5 is based on a completely new optical design which includes four elements made of high refraction glass, one extra-low dispersion lens and one aspherical lens. 11 elements in 9 groups deliver crisp details, vibrant colors and an ultra-low – 0,5% distortion. The circular 9-blade iris ensures a pleasant background blur and a smooth adjustment of the T- number from 1.5 to 22. With practically no focus breathing, the Irix Cine 45mm T1.5 is the perfect lens for filming scenes with a natural character.

Press release October 21st, 2019 — Irix Cinematic Design

The 45mm T1.5 is the third lens in the Irix Cine line which stands for a perfect combination of advanced technology and modern design. A good example of the Irix smart design is the front housing element which has a diameter of 95mm and a built-in 86mm filter thread. It also provides a magnetic mount for the reversible lens hood and for future Irix Cine accessories.

This synergy is also visible in the shape of the geared rings which have been integrated into the lens housing. The convenience of operating by hand and full compatibility with follow focus systems was a priority in the external design of the lens. You can use any follow focus system you like and position it wherever you want to thanks to a special rotating adaptive ring design. The adaptive ring can be adjusted to any desired position and expose the geared ring to couple with follow focus systems.

The Irix Cine line has been carefully deliberated from the start. The focus and aperture rings of all the lenses are aligned at the same height and have the same rotation angle. With the exception of the Irix

150mm T3.0 Macro 1:1, where a longer 270 degrees focus throw is necessary, the rest of the Irix Cine range lenses have ring rotations of 180 degrees for the focus ring and 75 degrees for the aperture ring.

Ready to shoot in any weather conditions

A high-class cinematic lens must work in any atmospheric condition. No matter if you are shooting on burning sand in the Sahara Desert or on the frozen peaks of the Himalayas – the Irix 45mm T1.5 is prepared to not only face it, but also to capture the best image possible. Every time. Enjoy your lens’ reliable construction with rubber seals placed in all the crucial points to ensure protection against rain or dust. Now, you can film anytime, anywhere – and seize the wondrous power of nature.

Your comfort is important! Focus and aperture marks are laser engraved and filled with UV paint. This makes them visible, even in low-light environments.

Versatility and compact in size

Irix Cine lenses are some of the most compact and lightest film lenses covering the full frame format. The housing is made of a lightweight and impact-resistant aluminum-magnesium alloy which has been successfully used and tested in the Irix Blackstone still lenses. Thanks to the low weight (every Irix Cine lens weighs about 1.1 kilograms / 2,4lbs), they can be used on smaller cameras on handheld rigs or stabilizers as well as on professional setups. In order to achieve greater comfort while working with follow focus systems, the Irix Cine lenses are equipped with a lens support foot. Depending on your needs, this support foot can be attached to the lower or upper part of the lens.
