Overview

The Canon 17-102 mm f/2.0 TV Zoom V6x17 is a vintage C-mount lens originally for ENG TV cameras, offering a constant f/2.0 aperture across its zoom range. Optically, it is relatively sharp wide open but exhibits heavy vignetting on Micro Four Thirds sensors, requiring cropping to ~1800×850. Bokeh is described as 'crazy' with visible internal mechanics. Build and handling are typical for C-mount; it focuses to infinity and fits standard C-mount adapters. It suits users seeking a fast, parfocal zoom for smaller sensors like the GH1 or BMPCC, willing to manage vignetting.
