IB/E K70 Series for 65mm Format Cameras

IB/E K70 Series – Precision Large Format Cine Lenses for Stunning 65mm Imagery

Expected to be available in Spring/Summer 2026

The IB/E 70 Series represent the pinnacle of optical engineering designed specifically for 65mm format cameras, including the ARRI ALEXA 265, Blackmagic URSA 17K, and Fujifilm GFX ETERNA. Crafted in Germany with premium materials and expert craftsmanship, these lenses deliver extraordinary image quality characterized by a perfect harmony of razor-sharp detail and beautifully smooth bokeh. Cinematographers can expect exceptional color fidelity and minimal chromatic aberration thanks to the advanced apochromatic color correction and aspheric elements incorporated in the optical design.

Designed to meet the demands of the new generation of large-format digital sensors, the IB/E 70 lenses combine cutting-edge technology with practical features that support demanding shoots. Each lens maintains a constant length during focusing due to internal focusing mechanics, ensuring stability and balance on any rig. 

With an aperture of T1.7 and industry-standard M0.8 gear wheels for iris and focus control, the set offers creative flexibility and precision. Lightweight and compact, these lenses are ideal for challenging production environments where portability and optical excellence must go hand in hand.

The IB/E 70 Series also supports advanced metadata integration through Cooke /i technology, providing seamless data capture on set. Available in both PL and LPL mounts, the lenses offer tuning options including customized flares, iris behavior, and color temperature adjustments. 

Built by a dedicated team in Bavaria, this lens series is a powerful tool for filmmakers aiming to achieve stunning cinematic visuals with a natural depth of field and perspective unique to the 65mm format.
