Xenon FF-Prime lenzen van Schneider-Kreuznach

Deze Full-Frame Primes zijn specifiek ontwikkeld voor de laatste generatie digitale film- en fotocamera's en hebben een oplossend vermogen dat belangrijk hoger ligt dan voor 4K chipsets vereist is, iets wat zelfs in de hogere segmenten van de markt verre van vanzelfsprekend is! De prijs/kwaliteitsverhouding van Xenon FF-Prime is ongelooflijk gunstig.

Goede camera's verdienen goed glas, en FF-Prime ís goed glas. Schneider-Kreuznach, al meer dan honderd jaar fabrikant van sublieme fotolenzen, projectielenzen, industriële optica en oogoptiek, heeft zich de laatste jaren met een verfrissende aanpak gericht op de sterk groeiende markt van cinematogtafische digitale camera's en DSLR's. De hieruit voortgekomen volledig nieuw ontworpen producten, waaronder Xenon FF- Prime, zijn internationaal met gejuich ontvangen.

Alle FF-Prime lenzen hebben dezelfde behuizing waardoor verwisselen van de lenzen op follow focus rigs en matte boxes verrassend eenvoudig is. Consistentie bij het wisselen van de lenzen is gegarandeerd door de helder leesbare focus en het gebruik van T-stops. De Xenon FF Prime lenzen zijn afzonderlijk of als complete set te koop.

FAQ

What is “Xenon FF-Prime”
Xenon FF-Prime is a family of prime lenses with fixed focal lengths. The “FF” stands for Full-Frame and means that the lens covers the full 36 mm x 24 mm sensor format. “Xenon” is a Schneider Kreuznach expression for a lens design with a high aperture.

What is this lens family made for?
Xenon FF-Prime is a lens family made for professional filming application. It can be used on HDSLR full frame sensor cameras with a good video mode like Canon D5 MK II + III or Nikon D 800 as well as on Blackmagic Ursa, Cinema Camera, Production Camera 4K and the other professional cine PL-mount cameras from ARRI, RED, Sony, Panasonic…

Which focal lengths does the range include?
The range includes the focal lengths 18 mm, 25 mm, 35 mm, 50 mm, 75 mm, 100 mm and 135 mm.
All of them T 2.1, except 18mm T2.4

Are the lenses available?
25mm, 35mm, 50mm, 75mm and 100mm FFPs are available
Expected release date of the 18 mm is Q1 2017
Expected release date of the 135 mm is Q4 2017

What is the price for the lenses?
35 mm, 50 mm, 75 mm and 100 mm: € 2998 /pc.
25 mm: € 4320
18mm: € 5498
135mm: t.b.d.

What is the difference between Xenon FF –Primes and Cine Xenar lenses?
Cine Xenar lenses are professional cine lenses in a price class of around €5.500/pc. They are designed and optimized for the S35 sensor format (24.9 mm x 18.7 mm) which is used in professional cine PL-mount cameras. The Cine Xenars have no visible breathing due to a telecentric design.
The Xenon FF-Primes are professional purpose-build cine lenses. They are designed for full-frame sensors (36 mm x 24 mm) and 4K resolution (the video mode of full-frame HDSLR cameras is typically 2K). The Xenon FF-Primes can also be used on PL-mount cameras with S35 and larger sensor formats.

What can you tell us about: robust mechanics, easy to use, reliable?
All Xenon FF Primes (25, 35, 50, 75, 100 mm) have the same T-Stop of T 2.1 and the exact same outer dimensions (diameters, length) and position of iris and focus gears. All lenses are color matched.
All those things are done to exchange the primes (focal length) as quick and easy as possible without any re-adjustment of light and accessories like follow-focus and matte box.
Compared to other lenses in a similar price range and that also cover full frame 36mmx24mm sensors, FF-Primes are purpose-build Cine lenses that cover a larger than S35 format with complete new optical and mechanical designs optimized for filming. It is NOT a rehoused photo lens design that is not optimized for filming, where the focusing process itself becomes visible (e.g. breathing). Designed for 4K resolution all FF-Primes perform a sharp image with high contrast. They have uniform dimensions, diameters and T-stops.

What is the optical performance of the lens?
The lenses are designed for full-frame 36x24mm and 4 K resolution, that means 40 line pairs. Fully open they have a “flary”, soft look, but stopped down to T 2.8 they have a sharp, high contrast picture. Due to their 14 iris blades they create a harmonious Bokeh. The breathing is optimized to a minimum. As menitioned earlier: all lenses are color matched.

What is the difference between other lenses in focus?
The focus of all focal lengths has a 300° rotation angle for precise working. This is realized by a cam, like in many professional cine lenses. The scale is spread in the longer distance marks and compressed in the shorter range for a continuous, regular movement over the whole distance without any image drop, jump or shift. The focus scales, feet or meter, are precise and readable from both sides.

What mounts are available?
The lenses are available with PL, Canon EOS, Nikon F, or Sony E mount. There is no electronic interface on any of the three mounts. The mounts can be exchanged and can be ordered additionally. The mount sets will include a shim set, screws and a mount cap. The back focus has then to be re-adjusted with shims, similar to the Zeiss CP.2 interchangeable mounts.
