In testing, I have a circle on a piece of paper. I need to mount a camera at a fixed distance so that the circle just captures the top and bottom of that circle.
Im testing this because I need to make a case for a camera that I do not have. But I do have 2 other cameras with the same 2/3in sensor size. So I figured I would test with them to take the measurements for the case.
When setting this up, one camera ends up being .5in closer than the other camera. I tested it with both a 12mm and a 16mm lens.
Both cameras are 2/3in sensors with a c-mount. I am literally using the same lenses for the measurements, just moving it to the other camera.
One camera is a 5mp sensor, the other is a 3.5Mp sensor. But I figured the sensor size being the same this wouldn't be an issue. Also the Flange focal distance of a c-mount lens is fixed too.
Any ideas on what could be causing this?
- The cameras are industrial video cameras made by allied vision. The prosillica GX 1920 and the manta 504
- I do not think this can be a viewfinder issue because I am reading the raw sensor output for the testing
