Telecentric lenses are designed so that the light exiting the rear element is perpendicular to the sensor. Non-telecentric lens designs allow the light to strike the sensor at an angle, which can lead to vignetting at the edge and corners of the sensor. The telecentric design of the lens minimizes vignetting.
This lens incorporates a port for a coaxial lighting device (not included). This setup enables you to illuminate the target area from the position of the lens itself, as opposed to setting up lights adjacent to your target.
Related Questions and Answers
Q: 1. works with blackmagic pocket 4k?
A: Yes, this is an MFT mount lens. It will work well with the Pocket Cinema Camera 4K. https://bhpho.to/2Hjgn8q
Q: 2. Do CP.3's allow for a protective filter to be screwed on?
A: No, for any filters you will have to use a matte box.
Q: 3. What is the hyperfocal distance at t 2.9 and focus set at 6 feet? is there a chart to show hyperfocal distance at various focus and Tstop settings?
A: The DOF tables for the ZEISS Compact Prime CP.3 lenses can be viewed on the ZEISS website: https://www.zeiss.com/content/dam/camera-lenses/files/service/download-center/depth-of-field-tables/depth-of-field-tables-zeiss-compact-prime-cp3-lenses-feet.pdf
Q: 4. File size limited to 5-minute intervals - 1 hour file size is preferred ?
A: Set the Hanwha Techwin XNB-6001 2MP Network Modular Camera Base Unit BH #HAXNB6001 for continuous recording rather than motion detection event recording in areas where motion detection is frequent. Since the log is recorded once every 5 minutes, the buffered motion detection log data may be damaged when the power is turned off.
Q: 5. What's FOV angle of this lens when used with 2/3 5MP sensor?
A: 2/3 sensor, 8mm lens = FOV H 57.62 degrees, V 4483 degrees.
Q: 6. Is there a 65mm CP3?
A: No, there is not a 65mm version of the ZEISS CP.3 85mm T2.1 Compact Prime Lens (PL Mount, Feet).
Q: 7. I'm looking for a 1:1 custom mount to a 16 mm animation stand camera (ACME - Photo Sonics prism viewfinder camera) Will this lens adapt?
A: The Computar 1.1" 25mm f/2.8 12MP Ultra Low Distortion Lens (C-Mount), should mount and offer compatibility with your camera, as long as it features a C-Mount.
Q: 8. does this also work on super 35 ?
A: Yes it does.
Q: 9. Will this work with the FX3?
A: Yes, the ZEISS CP.3 35mm T2.1 Compact Prime Lens (Sony E Mount, Feet) is compatible with the Sony FX3.
Q: 10. Does this require a locking mechanism in the mount? I’d like to use it on the FX6
A: The ZEISS CP3 lenses incorporate a 3/8" thread support bracket at the bottom of the barrel. This can be tied into a camera support rig to isolate the lens from the camera and prevent any movement in the mount as the focus is racked.
