Hi there,
for an upcoming project we will have to camera match drone footage (stills). The drone camera will be a Sony A6500 with a Zeis 16-35 mm F4 lens
We are investigating from which positions we need stills and shots.
So we are adapting the render output size and the Corona Camera settings (3DS Max) to mimic the Sony camera and lens.
- If I am not mistaken the Film width (mm) parameter in Corona Camera should be the value off the sensor size of the camera. For the Sony A6500 this should be 23.5 mm (sensor size = 23.5 mm x 15.6 mm) source:
https://www.digicamdb.com/specs/sony_alpha-a6500/ .
But the tooltip mentions a value of 25.1mm for ASP-C digital SLR's. Which refers to the Classic film negative format
https://en.wikipedia.org/wiki/APS-C- Considering the focal length of the lens AFAIK when setting the film width for an APS-C camera we do not have to take the crop factor (1.53 for the A6500) into account. So 16mm stays 16 mm.
So, should we use the 23.5 mm or 25.1 mm for the Film Width and may we ignore the crop factor to get approx the correct results?
