Irix 11mm T4.3 Canon EF mount Cinema lens 8K IL-C11-EF

The Irix Cine 11mm T4.3 is the full frame cine lens, ready for capture image with 8K UHD resolution. 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 moderate wide angle of view for classic wide-angle shots or super-panoramic 123 degree viewing angle in a 2.39:1 widescreen format.
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 last two are made with low-dispersion glass (ED). The use of 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.
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 imperial units.
Thanks to the another innovative solution like adaptive ring, the Irix Cine 11mm T4.3 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 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 variety 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.
