Super Cinelux 35
Used in cinemas throughout the world, Schneider Super-Cinelux 35 lenses have long been the choice for uncompromising optical performance. With the recently redesigned short focal lengths and the new range of lenses in increments of 2mm and 2.5mm, it is easy to fill your screen with sharp and bright images of the correct size.
Due to their exceptional depth of field and distortion correction, Schneider Super-Cinelux lenses can meet the high standards of performance demanded by today's large curved screens and quality demanding theatre audiences. For the ultimate in extra-wide performance, the new wide lenses start with the 24mm - the widest F/2.0 image in history.
Cinelux Ultra
The Cinelux-Ultra lenses are high-performance 35mm and 70mm (5 perf) projection lenses. Designed to incorporate state-of-the art technical advances resulting in exceptional corner resolution capability with superior brilliance and optimum distribution of illumination over the whole picture area.
The Cinelux-Ultra is a 6-element double Gauss lens system. Two convergent lenses are placed front and rear, with two divergent lenses with their concave surfaces face-to-face in the middle, to form the system.
Cemented surfaces are not used so as to reduce heat damage. Cylindrical curvature of 0.1mm to 0.2mm in the film gate has been incorporated to give excellent corner contrast. The latest technology in anti-reflection multi-coating is applied to all glass surfaces to achieve maximum light distribution over the entire image field. All lenses are available with 70.65mm or 62.5mm diameter mounts and 45mm and longer focal lengths can be used in conjunction with anamorphic attachments.

Schneider has developed the first series of Variable Prime projection lenses.
The Variable Prime VP-CINELUX series consists of 13 lenses that have the unique property of adjustable focal length. With their 7% range of picture size adjustment, the image they project can be precisely sized to fit the screen. These lenses are correctly called Variable Prime lenses. They are not zoom lenses, so they do not have the performance compromises and light-loss associated with zooms. They are all fast F/2 lenses, projecting large quantities of light and producing bright, uniformly illuminated, high-resolution images even on the largest of screens.
The new Variable Prime VP-CINELUX is the only adjustable focal length lens series available for 35mm film projection. Schneider Variable Primes are available in overlapping focal lengths ranging from 28.9 to 61.1mm, all at F/2.0. Even using the extremely wide-angle 28.9mm, this F/2.0 lens system's illumination is uniform from corner to corner; allowing virtually all of the light from today's larger lamphouses to be transferred to the biggest of screens.
In today's theatres it is not uncommon for 10% or more of the image to be lost to cropping. This results in a loss of light level and reduced image quality. A correctly sized image with little or no cropping will be substantially brighter and sharper than an over-enlarged and cropped image. A Schneider Variable Prime VP-CINELUX, set at exactly the correct image size to fill the screen, is a more cost effective solution than a larger sized lamp. It also improves image quality, which a lamp can't do.
VP-CINELUX lenses are equipped with a robust and secure focal length micro-adjustment and locking mechanism. Focal length adjustments and locking are done with a 3mm metric ball-head tool supplied with each lens. Because the focal length adjustment and lock mechanisms can only be operated with this tool, these lenses are less likely to be subject to unauthorized adjustments. This allows rapid last-minute image size adjustments to accommodate masking or screen changes.
Anamorphics
Anamorphic lenses are used to squeeze an image in widescreen cinematography or un-squeeze the image for widescreen projection. Usually the image is squeezed horizontally during photography and un-squeezed horizontally during projection. The most recognized trade name for this process is Cinemascope®.
Anamorphic lenses are constructed using cylindrically shaped lenses, instead of the spherically shaped lenses used in conventional lenses.
While technically an anamorphic can be made to have more or less "squeeze," the most common "squeeze factor" is 2x, which is the factor used by the Cinemascope® process.
