Lightening fast 1.0 WOW! Just look at that fast rear glass!C-MOUNT These are incredible lenses with high quality razor sharp image commonly used on new digital movie and film cameras. You will have to do research for exact application. Using crop mode, 3/2 aspect ratio, ETC, zoom, or windowing mode etc is necessary on some. I will not be held responsibly for vignetting, adapter fitments etc. NOT for use on c-mount adapters. These lenses will not fit because the chrome barrel is too wide for the adapter. Please be fair to us and don't turn on us because a lens doesn't adapt. YOU MUST DO RESEARCH AND EXPERIMENT. It is not our fault if it doesn't work. Moreover, they make a mistake and won't take responsibility for it and turn on us because it's the easy way out. You can always RESELL the lens.
