Irix Announce 150mm f/2.8 Macro 1:1 Lens For Full Frame Cameras

Written by Gina Stephens

Irix has published a new 150mm f/2.8 optic which will be on show at Photokina 2018.

The Irix 150mm f/2.8 Macro 1:1 is designed for full frame cameras with the Nikon F, Canon EF, and Pentax K mount. With its centred length of 150mm and 1:1 scale of reproduction, the new lens allows comfort when working with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel small objects. Thanks to the possibility of being talented to move away from the photographed object, this makes the operation more convenient than using lenses with a shorter centralized length. No shadows are cast on the object and it is also possible to use lamps dedicated to this type of photography. 
The Irix 150mm f/2.8 Macro 1:1 lens is attired with an aperture mechanism consisting of 11 rounded blades that maintain a circular shape within the entire available working limit. Thanks to this, when shooting with a wide open aperture, a pleasant background blur is obtained; when closed right down, the diffraction arrives much later. This ensures much greater detail. 

The focus ring has been equipped with a wide rubber control with a special convexity pressing to facilitate precise focusing of the scale, with 270 degree rotation. The whole design is complemented by a going Focus Lock ring that allows you to lock the focus ring at a convenient position. 

The Irix 150mm f / 2.8 Macro 1:1 lens has been sealed at key points (the fore-part element, the Focus Lock ring, the focusing ring and bayonet), making it suitable for use in the harshest of weather conditions such as fog, rain or snow.

The optical scheme consists of twelve elements – three of which are made of super-low dispersion glass (ED), another four of glass with a higher refractive formula (HR), and the whole arranged into nine optical groups. Thanks to this construction, the lens can acheive close to zero distortion (at a level of 0.1{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff}). 

The Irix 150mm f/2.8 Macro 1:1 lens is furnished with an internal focusing system (IF) so that the lens does not change its dimensions when focusing, thus maintaining a compact size and safer sealing. 

The Irix 150mm f / 2.8 Macro 1:1 lens is the first model available in the new version with the Dragonfly finish, in which the aluminium schema has been enclosed in an external structure made of aluminium-magnesium alloys and composite elements. The combination of Firefly and Blackstone features gave the lens lightness and solidity while supporting high mechanical strength and resistance in difficult weather conditions. 
The lens has a CPU that allows control of the lens aperture from camera up to date on, and the AE module allows the use of semi-automatic modes (PASM). This solution allows the user to get confirmation of the focus from the camera. An additional benefit is the recording of danger data in the EXIT format. 

The lens kit will include: 

  • Practical deep lens hood that isolates the lens from sidelight outsets and also protects the front element of the lens from minor damage
  • A rigid lens case for safe transport and storage
  • A detachable tripod collar (Arca Swiss pattern), allowing you to transfer the weight that is the centre of gravity to the front and securely place the camera on a tripod.
