Mobile lens evaluation checks in16 September 2017
The new LensChecker is a compact and mobile tool to evaluate lenses by projection, and can be used for a wide variety of cine, stills and vintage lenses, up to full frame format (image circle).It has been designed to fit in a trolley case for easy transportation and can be used for presentation or in-depth evaluation of lenses during check-in or check-out at a rental house,or in the field.
The €6,000, 3.5kg LensChecker can evaluate the optical performance of a lens (axis and off-axis), resolution, geometric distortion, chromatic aberrations, breathing (image size change while focusing), back focus (fixed reticle), focus marks, and alignment of the optical assembly (spherical and anamorphic).
For zoom lenses it also analyses centre tracking and zoom curve (back focus while zooming).
It has been developed with StarKish and is manufactured by P+S Technik in Germany. It uses the Interchangeable Mount System, and currently works with Arri PL, BNC-R, B4, C-mount, Canon EF, Canon FD, Leica M, Leica R, Nikon F and Panavision.
