This has been driving me crazy. I've been trying to render out a shot at a very wide focal length, about 8mm. When I render, the first frame renders at 8, but then every frame after that renders at 10mm. I've done some trial and error for different focal lengths and it seems that below 10mm it renders frame 1 normally, then defaults back to 10 for the rest. Does anyone know what is happening, or is this just a limitation?

Can you increase the sensor width instead? You should be able to produce the same field of view while keeping the focal length above the 10mm limit. You can compute the equivalent sensor width from trigonometry.

Hi, Did you find a solution ? I have the same problem. Where are you supposed to find the sensor width ? Thanks !

fond it. but I have the same problem.
Focal Length 15, Sensor Size 74, same problem as mention. first frame ok, then second fall back to probably 15 / 52.5.
