KIPON BAVEYES Cine Extender 2x is designed to double the focal length of cine lenses. The adapter allows light to pass through up to an aperture of 1.4. During the design process, care was taken to leave the character of the lenses used largely unchanged and to ensure the greatest possible compatibility with as many lenses as possible. With a max. immersion depth of 22mm (PL mount), the 2x extender is compatible with a wide range of cine prime and zoom lenses.
The optical design consisting of 7 lenses in 4 groups uses high refractive index and low dispersion glass and has been optimized for maximum contrast transmission and minimum aberrations with state-of-the-art optical design software. Tolerance and stray light analysis by special software, avoids ghosting and reflections already at the design stage and ensures maximum imaging performance.
An integrated option to finely adjust the flange focal distance via rotary wheel (FFD Adjustment +/- 0.05mm), allows a quick fine tuning of the flange focal distance without the use of tools and shims. The extender is pre-adjusted to 52mm flange focal length (PL FFD) ex works.
