UPDATE: Last week Irix announced that it was introducing its four cinema lenses in the Canon RF mount. Now it tells us that it has also decided to produce these specialist videomaking primes for the Nikon Z mirrorless mount – and for use on the L-mount used by full frame Panasonic, Leica and Sigma cameras. All the lenses are available to order immediately.
ORIGINAL STORY (30 September): Irix has announced that all four of its existing cinema lenses will be available in Canon RF fit. The new mount will be offered on its 11mm T4.3 Cine, 15mm T2.6 Cine, 45mm T1.5 Cine, and 150mm T3.0 Cine lenses; these primes are already available in Sony E, Canon EF, Arri PL, and MFT mounts.
The logical move means that this range of affordable cine lenses can be used with the new 8K Canon EOS R5 mirrorless camera, as well as with the newly-announced Canon EOS C70 cinema camera – which will become the first-ever cinema camera to use the RF mount.
Venus Optics also announced that it would be producing three cine lenses for the RF mount earlier today.
Irix tells us that four lenses have a weight similar to the new EOS C70 camera, "guaranteeing a good balance of the entire set, which is extremely important when using stabilizing systems such as a gimbal or Steadycam. The use of the native RF mount ensures not only comfort but also work safety, guaranteeing tightness of the connection and rigidity of the entire set, which is a key feature when using automated follow-focus systems."
The four lenses are available for pre-order now, and will cost €1195 each (approx $1400 / £1100).
