MAINTENANCE
The lenses have an anti-reflective coating and are dirt resistant. However, they are not scratch-proof. Use only cleaning agents intended for optics. Larger impurities should be removed first with compressed air or with a clean soft brush.
WARNINGS
The lens is equipped with rubber seals to protect the interior from dust and
moisture. It is not, however, completely waterproof. Do not submerge it in
water or store it for extended periods of time in humid places. To achieve
better water-tightness, the use of the front protective filter is recommended.
Protect the lens from shock, being dropped, and excessive vibration, and do
not leave the lens in direct sunlight as a focused light beam may cause a
fire.
Do not expose the lens to high temperatures.
Do not look through the lens at the sun or in its general direction, as that
may cause permanent eye damage.
The lens and its accessories should be kept away from children and animals, as
they contain small elements that constitute a choking hazard.
Unsupervised dismantling of the lens may lead to permanent damage and loss of
warranty.
In the case of any faulty operation, it is strongly recommended that you
contact the authorized Irix service point.
Thank you for choosing our product. Your new lens has been designed with both
the effort and experience of not only engineers but also cinematographers. It
has been created based on the best available materials, technology and
solutions, thus making it the perfect tool for both professionals and
hobbyists.
The Irix Cine 15 mm T2.6 is a full-frame cinema lens with a wide-angle view.
It is designed for cameras with sensor diagonal sizes up to 43,3 mm.
[1] FRONT LENS CAP
The front lens cap protects the front lens and should always be put in place
whenever the lens is not being used.
[2] FRONT FILTER THREAD
The design of the lens allows the use of 86mm screw-in filters.
Screw the filter clockwise as viewed from the front lens. Before fully
screwing on the filter, make sure the lens does not come into contact with the
filter’s glass surface, as this may cause damage to both components.
[3] LENS HOOD
Using the lens hood improves contrast and protects the front lens against dirt
and mechanical damage.
The lens hood has an easy-to-use magnetic mount with a positioning system. To
save space the lens hood can be attached in a reversed position during
transport.
WARNINGS
Do not hold the lens by the lens hood, as this may cause the lens hood to
detach and cause the lens to fall.
[4] LENS SUPPORT FOOT
The support foot is a standard feature of the Irix Cine 15mm T2.6 lens.
The lens is equipped with a detachable foot for supporting the lens when using
follow focus system on rods. Depending on the following focus configuration,
the foot can be attached at the bottom or top position of the lens.
WARNINGS
The foot is not suitable for mounting a camera with the lens directly on a
tripod. Using it to attach the lens to the tripod may lead to damage to both
the lens and a camera.
[5] ADAPTING RING FOR FOLLOW FOCUS SYSTEM
The lens is equipped with a unique rotating adaptive ring for follow focus
systems. It provides an easier fit for your focus gear, to the focus ring from
any angle. The ring can be rotated 360° with increments of 15 degrees
[6] FOCUS RING
To focus on a given object, look at the image in the viewfinder or on the
camera screen and adjust it manually by rotating the focus ring. You can also
use the distance scale on the lens body to estimate the distance to the chosen
object for the scene. The focus ring can be rotated by hand or by using the
following focus system in the range of 0,25 m (9.84″) to infinity.
[7] LENS MOUNT
Mounting the lens to the camera as described in the camera’s user manual may
differ with various systems.
The marker (dot) on the lens body facilitates mounting the lens onto the
camera.
[8] REAR LENS CAP
The rear lens cap protects the lens during transport and should be put in
place whenever the lens is not attached to the camera.
[9] APERTURE RING
The aperture ring allows for smooth adjustment of the T number of the lens in
the range from T2.6 to T22. The ring can be rotated by hand or by using the
following focus system.
