      Comments about EverFocus EFV-550-DC Varifocal CS-Mount Lens:

      I looked for a CS mount lens like this and saw I could pay over three times as much for the same basic specs. My application is low budget movie-to-video transfers, and for the way I'm doing them the results with this lens were outstanding.
