Canon TV Zoom Lens V6x17 17-102/2.0 was the first C-mount zoom I've ever got. First of all, it was smaller than I suspected. It makes the lens perfect for multi-purpose use. It's 16x zoom with very fast aperture of 2.0.
Secondary, I've read somewhere that it's supposed to be parfocal, that is - focused on the narrower length (102 mm) will stay in focus throughout the whole zoom range. It was really pity, that mine wasn't. What's more - it didn't focus at 17-20 mm at all! Luckily - there was a simple trick and now everything's superb!
All in all, it became my favourite lens for shooting squares and filming.
