German optical specialist, Schneider-Kreuznach is showing its new range of Xenon full-frame prime lenses at IBC. The lenses are designed for 4K resolution (4096×2304 pixels) and have been developed especially for DSLR cameras with full-frame sensors for video shooting, although they can also be used with professional cine cameras.
They come in five fixed focal lengths: 35mm, 50mm and 75mm (all available now), while a 25mm wide angle and a 100mm telephoto lens are due in early 2014. All have a standard aperture of T2.1 as well as identical external dimensions and positioning of the controls in all lenses. The series will be expanded later with a macro lens and further focal lengths.
“This series of prime lenses has been especially designed for full-frame sensors and meets users’ exceptionally high demands in terms of optical performance and ease of use,” claimed Daniela Kesselem, product manager at Schneider-Kreuznach. All the lenses can be used for either Nikon and Canon DSLR full-frame cameras with corresponding F or EF bayonet mounts, as well as professional film cameras with a PL-mount. All the lenses are colour-matched.
They can be used with standard professional cine accessories like rigs, follow focus or matte boxes. Special features required for filming such as minimised breathing, a harmonious bokeh (thanks to a circular aperture with 14 blades) and reduced stray light have also been optimised. Other features include manual, precise and reproducible focus settings with a 300° angle of rotation, larger focus and distance scales for easier focusing even with greater distances, readable on both sides, M95 filter thread, and an exchangeable bayonet interface.
