Schneider Xenon FF 25mm T2.1 Lens with Canon EF Mount - Feet
Covers a full frame image sensor without vignetting and is designed for 4K image capture
The Schneider 25mm T2.1 Xenon prime lens is specially designed for digital cinematography on full-frame digital SLRs. The circular 14-blade aperture is specially engineered for a smooth and consistent bokeh. The precision constant volume focusing design ensures that breathing is minimised and with a 300-degree barrel rotation, the manual focus markings ensure accurate focusing. Additionally all lenses are colour-matched for consistency. Engineered for compatibility with industry standard cine-style accessories like follow focus rigs and matteboxes, the Xenon full-frame lenses feature identical external dimensions and positioning of focus and gear rings in each focal length.
Purpose Built for Today’s Full Frame Sensor Cameras
Designed especially for digital cinematography with today’s HDSLR and other cameras, the new Xenon full-frame lenses are the fi rst fully professional, affordable primes that are optimized for 4K sensors and greater and deliver outstanding results under 4K as well. They elegantly cover the full 43.3 mm image circle that’s usable on Canon 5D Mark III and Nikon D800 cameras. With an all-new optical and mechanical design that combines leading edge technology, combined with time-honored expertise, FF-Primes facilitate outstanding images tailored to top digital cinematography cameras today and beyond.
Quick Change Artist
Focus and iris gearing is uniformly positioned from lens to lens so that follow focus mechanisms, motors, and other accessories needn’t be painstakingly repositioned each time a lens is changed - a real time-saver. And to accommodate standard filters and other accessories, each FF-Prime lens has a 100 mm front diameter with standard 95 mm thread (only 18 mm has no thread).
Cam Driven Constant Volume Focus
Incorporating the most up-to-date optical and mechanical design features, the FF-Primes utilize a cam driven focus instead of the helical thread commonly found on photo-based lenses. The cam permits more evenly spaced focus marks so focus is easier and more intuitive. The relatively uniform weight of the lenses greatly simplifi es setting counterbalance on both tripod heads and specialty camera support equipment like Steadicam and MoVI stabilizers. Cam driven focus and precisely calibrated focus scales provide accuracy and repeatability you can rely on.
Accurate and Visible Markings
FF-Primes feature oversized, bright and clean, easy-to-read focus and iris marks on both sides of the lens so they can easily read regardless of where the Assistant is positioned. The distinctive focal length numerals are bold and san serif - for quick viewing in any light. With a 300° barrel rotation, the manual focus markings support precise accuracy and dead-on repeatability.
Colour Matching Throughout the Line
Costly colour correction is minimized when the image is acquired through a Schneider-Kreuznach prime. Each Xenon is color matched to the others in the set thanks to Schneider-Kreuznach’s expert optical engineering and proprietary lens coatings.
Proprietary 14-Blade Iris on Every Lens
Fourteen identical precision honed blades form the meticulously precise circular aperture that lets the light into each FF-Prime. Every T stop on every lens in the family provides a pleasing and consistent bokeh that rivals the finest film lenses.
Flare Optimisation and "Film Look"
Engineering a lens from the ground up is a delicate balance of mechanics, glass and coatings. Schneider-Kreuznach’s outstanding engineers have specified and selected the finest glass and applied propriety anti-reflection coatings to suppress unwanted flare. Most cinematographers agree that FF-Primes have a pleasing "film look" and the near telecentric design minimizes breathing while pulling focus.

Robust and Reliable, Guaranteed
Schneider-Kreuznach Xenon FF-Primes are built for action. With 100 years in the photography field Schneider-Kreuznach understands the rigors of life on the set. So FF-Primes are built to move with you through repeated focus and iris changes. The lens’ mechanics are built to stand up through the shoot and over the years.
