Canon has announced the launch of two new Super 35mm lenses in its Flex Zoom line-up, the CN-E 14-35mm T1.7 L and CN-E 31.5-95mm T1.7 L. There are the fastest Super 35mm lenses on the market with these focal ranges. Canon claims that they offer incredible optical performance to support a wide range of uses and shooting scenarios.
   

These two new zooms join the existing full frame CN-E 20-50mm T2.4 and CN-E 45-135mm T2.4 lenses in the Flex series.

With the CN-E14-35mm T1.7 L and CN-E31.5-95mm T1.7 L offering a fast constant aperture of T1.7 you will be able to interchange and use them with fast primes on the same production. You could also make a strong case for using them instead of primes for fast-paced productions that need to get through a lot of pages each day.

Canon states that the CN-E 14-35mm T1.7 L and CN-E 31.5-95mm T1.7 L lenses feature a compact and lightweight design, however, they weigh 3.3kg and 3.5kg respectively. This is not exactly lightweight, but given their fast constant T stop it is still reasonable.

Both lenses feature an 11-blade iris and industry standard 0.8 pitch gears on the iris, zoom, and focus rings.

Switch from S35 to full frame

The lenses feature an interchangeable mount design that enables them to be switched between EF and PL mounts.

The flange back can be adjusted when changing lenses. The adjustment mechanism has a cap that prevents unintentional shifting of the flange back. Adjustments can be made using a flat-head screwdriver.

Additionally, in a first for Canon’s cinema range, these lenses can take advantage of Canon’s new interchangeable relay kits. The new relay kits are the RL-S1, RL-S2, RL-F1 and RL-F2.

The relay kit enables the lenses to be switched from Super 35mm to Full Frame and back again, however, this can only be done at a Canon-authorized service center and it will incur a fee.

These relay kits can be used to turn the CN-E 20-50mm T2.4 and CN-E 45-135mm T2.4 lenses into a 14-35 T1.7 and a 31.5-95mm respectively.

This is very similar to what Angenieux does with its EZ Zoom series.

Enhanced Communication

Both lenses support efficient lens metadata workflows including Cooke /i Technology, and ZEISS eXtended Data via PL mount, alongside 4-pin Lemo connectivity. This is invaluable for virtual productions, where positional information is needed to ensure virtual backgrounds react as a natural background would to the perspective of the camera, as well as for post-production VFX workflows. Furthermore, electronic lens communication with chromatic aberration and peripheral illumination correction, as well as a Dual Pixel Focus Guide for manual focus assist via EF mount is available when used with compatible cameras.

Price & Availability

The CN-E 14-35mm T1.7 L S / SP, RL-S1 (CN-E 14-35mm T1.7 L S / SP relay kit) and RL-F1 (CN-E 20-50mm T2.4 L F / FP relay kit) will be available in late June 2023 and the CN-E 31.5-95mm T1.7 L S / SP, RL-S2 (CN-E 31.5-95mm T1.7 L S / SP relay kit) and RL-F2 (CN-E 45-135mm T2.4 L F / FP relay kit) will be available from late October 2023.
