Phase One XT 90mm lens : Seek extraordinary
Known for their great resolving power and contrast even at large apertures, the optical design of Rodenstock HR lenses reduces diffraction and colour noise, even at the pixel density of the IQ4 150MP, providing further flexibility to the full frame medium format sensor.
With Rodenstock as a strategic partner, the introduction of these exclusive, digitally integrated lenses is only the beginning of the XT Camera System lens range. Now with the XT 90mm lens, the 67°field of view will get you closer to the subject to provide micro detailed images. It also has a very large image circle meaning that it can utilise the full extent of the shift movement on the the XT camera allowing for multi image panoramic stitching.
The XT lens family now stands with the current 23mm, 32mm Tilt, 40mm Tilt, 50mm Tilt, 70mm & 90mm lenses. There is a focal length longer than 100mm in the works, more details on this as they come to hand.
X-Shutter
At the heart of the XT – Rodenstock HR lenses is the X-Shutter. The X-Shutter is an intelligently integrated and electronically controlled shutter, born out of Phase One’s industrial applications and experience. The X-Shutter is purpose-built for the XT Camera System to allow for finer control in a smaller form factor. Powered by the IQ4, the X-Shutter shares in the ambition of the Infinity Platform for future growth and flexibility.
