150mm T 3.0 macro 1:1 – the first of a new cinematography line from Irix with the full-frame sensor lense.
The new line of Irix Cine Lenses is created in close cooperation with professional filmmakers; their ideas and suggestions were an important factor in the design process. The designers earlier experience in the field of photography led us to create new and better solutions for the Irix Cine products.
The Irix Cine 150mm T3.0 Macro 1:1 is the first lens in a new line of full frame sensor cine lenses, ready for 8K UHD. It’s complex optical system is based on the same optical layout used in the Irix 150mm f/2.8 Macro 1:1. The lens consists of 12 optical elements arranged in 9 groups, four of which are high refractive index (HR) glass, and three low-dispersion glass (ED). Because of those elements, this lens offers superb high resolution, nearly zero chromatic aberration and has almost no visible distortion (as low as 0,1%).
The optical system is equipped with an internal focusing system. The lens was designed to have as little breathing as possible.
For the camera operators, a good and tough housing is very important. Irix is known for fine mechanical constructions, and in the Cine range we pushed this even further, focussing on superb operation ergonomics and a high precision mechanism. Quiet and smooth rotation of the focus ring was achieved thanks to the new MST lens positioning system - created specially for the Irix Cine range. The Multi Start Thread mechanism, in combination with sealed housing, ensures durable and long-term operation of the lens in various atmospheric conditions even in the most demanding situations. The rotation angle of the focus ring is increased to 270 degrees, which makes focusing easy and accurate at any range. The lens will be available with both metric and imperial markings.
Highest attention has been paid to the aperture mechanism in these optics, where eleven iris blades with rounded edges create great bokeh and sharpness. The Irix Cine 150mm also significantly reduces the diffraction effect when filming at low aperture values. The de-clicked aperture ranges from T3.0 to T32. The aperture ring rotates 75 degrees.
Unique design and well thought-out ergonomics
The Irix Cine 150mm T3.0 Macro 1:1 lens stands out for it’s great ergonomics and design. The side edges of the focus gear-rings are shielded by a special ring, providing a larger area for better manual handling - whilst still compatible with follow-focus systems. Further information about the Adaptive Ring System will be provided later. The markings on the lens are laser engraved and treated with UV fluorescent paint, to improve the readability in low light conditions.
Prepared for all weather conditions
The Irix Cine 150 mm T3.0 Macro 1:1 has been designed as a versatile tool in the hands of a filmmaker, built to withstand various weather conditions. The housing is equipped with several seals to create a barrier for dust, rain and accidental splashes of water. The design of sealed construction ensures safety of the optical lens system and the camera sensor.
The exceptional functionality and innovative solutions are a distinctive feature of all Irix products. This lens has been equipped with an unique Magnetic Mount System for accessories. The MMS system allows quick and easy attachment of variety dedicated accessories. The first of the new MMS accessories is the detachable and reversible lens hood (included with a lens). More accessories coming soon.
Created to be part of the cine gear family
Making innovations doesn’t mean we resign from the industry standards. We know how important compatibility is for a filmmaker, with other accessories. Irix Cine lenses have standardized front diameter 95mm for matte box, 86mm front filter thread, unified distance between gear-rings within the whole family range (future developments), standardized 0,8 pitch module gears, unified angles of rotation, and similar weight. The Irix Cine 150mm T3.0 lens is equipped with a removable support foot with a 1/4 thread to protect the camera mout and allow the lens to be stable at all times while using a follow focus system, and protects the camera mount. The support foot can be attached on the bottom or top of the lens for convenience of use.
