Lens manufacturer Irix has launched a new 11mm T4.3 lens for Canon EF, Sony E, MFT and Arri PL camera systems.

The lens, which appears to be a cine version of its 11mm F/4 lens, is constructed with a magnesium housing with various rubber seals for weather resistance. It’s comprised of 16 elements including four high-refractive index (HR) elements, three aspherical elements and two low-dispersion (ED) elements.

The lens weighs 1.1kg (2.43lbs) and features Irix’s Magnetic Mount System, which makes it easy to attach compatible accessories, including the lens hood. Irix has also added its new Multi Start Thread focusing mechanism, which ‘allows quiet and precise focusing even under adverse weather conditions such as rain, humidity or extreme temperatures.’

Other features include a 95mm diameter front flange and Mod 0.8 standard geared rings.

The 11mm T4.3 cine lens will be offered in Arri PL, Canon EF, MFT and Sony E mounts. Pricing and availability has not yet been announced, but ‘will be available shortly.’ For more information, keep up to date on the Irix website.

Irix Cine 11mm T4.3

IRIX, known for high mechanical and optical quality, pleasantly presents the 11mm T4.3 – the second full-frame lens from its new cinematography line. Enjoy the new perspective of super panoramic film shots made with Irix Cine lens!

Irix 11mm T4.3 is the second unique lens from the new Cine line. Its extremely short focal length, rectilinear image projection and the large image circle of 43.3mm (covering the full-frame format) make it one of the most outstanding cine lenses on the market. Depending on the diagonal of the sensor, the lens can provide a moderately wide angle of view for classic wide-angle shots or super-panoramic 123-degree viewing angle in a 2.39:1 widescreen format. Irix 11mm T4.3 thanks to its unique parameters, provides a perspective not available in film optics, thus releasing creativity in creating dynamic shots.SAR

The same, but different optics
The lens optical system is based on the new optical formula, developed especially for cinematic purpose. It consists of 16 optical elements, which four are made with high refractive index (HR) glass, three other have aspherical surfaces and the last two are made with low-dispersion glass (ED). The use of the large front lens and other special glass elements provides crisp cinematic shots in a resolution up to 8K while keeping the focus “breathing” effect at the lowest level. The lens offers a large maximum T number of 4.3 which can be reduced to T22, thanks to the 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 a focusing scale with metric or imperial units.

Thanks to another innovative solution like the adaptive ring, the Irix Cine 11mm T4.3 ensures great ergonomics of operation both by hand and with follow focus mechanism. Moreover, despite 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 is a distinctive feature of all Irix products. The same applies to the Irix Cine 11mm T4.3, whose extremely compact design (weights 1,1 kg) has been also equipped with an innovative Magnetic Mount System for accessories. The MMS system allows quick and easy attachment of a variety of dedicated accessories. The lens hood included in the kit with the lens is the first element of the MMS system. The system will be expanded with further accessories in the future.

Prepared for all weather conditions
The ultra-wide field of view of the Irix 11mm T4.3 means that its natural work environment is outdoor. It’s durable magnesium housing and numerous rubber seals guarantee the safety of both the optical system and the camera sensor in every weather conditions.

Designed to work in accordance with film industry standards
The 11mm T4.3 is another lens of the Irix Cine line that proves the newest technical solutions can perfectly harmonize with well-established film industry standards. The lens has a front flange with a diameter of 95mm and geared rings in the Mod 0.8 standard, which ensures its compatibility with most cine gear accessories. Attention to maintaining the standard also applies to the family of Irix cine lenses whose geared rings are in the same position and have unified rotation angle.
