Newsshooter at NAB 2014: GL Optix latest lens lineup includes Canon 70-200 cine mod from Dan Chung on Vimeo.
Clinton Harn talks to Nan from GL Optics about their new lenses, the most interesting of which is their updated Cine conversion of the Canon 70-200 f2.8 lens. Interestingly the lens is also calibrated to parfocal.
The Chinese lens conversion experts also showed cine converted Leica R lenses and also a revised version of their Sigma 18-35 f1.8 conversion with a greater focus throw.
