developments in prime and zoom
lenses for the broadcast and digital film
markets. The year since InBroadcast
last looked at this sector has seen
new introductions from many of the
leading manufacturers with 4K now
firmly established as the preferred
resolution for all content likely to
have a long shelf life. Recent months
have also seen new 8K camera lenses
from Canon, Fujinon and Irix.
Angénieux' Optimo Primes Series
is a joint effort with Band Pro Film
& Digital and Jebsen Industrial
Technology. The series is designed
to complement Optimo Ultra

mm focal lengths. 18, 24, 32,

in the process of being introduced.
Optimo Primes provide a minimum
coverage of 46.5 mm image circle.
All focal lengths are PL mount. Cooke
/i Technology and Arri LDS metadata
are supported. A common gear size
and position are used across the
entire 12-lens set. Each lens in the 12

was designed to provide the best
compactness and weight (ranging from
1.7 kg to 2.3 kg or 3.75 to 5.07 lbs)
while offering aperture at a fast T1.8
(with the exception of the 18mm and
200mm, at T2 and T2.2 respectively).
