Reply To: How to change aperture in Canon xa30 while recording?


I can’t speak to “all” camcorders. However, I shoot with a Sony NX5U. When beginning to shoot the iris can be set manually from f2.8 to f16. As soon as the camera is zoomed, however, the iris automatically resets to f3.4 and cannot be reset to a wider opening. According to what I’ve been able to determine, Sony considers f3.4 to be the “sweet spot” for that lens and establishing that as the iris open.

Frankly, it’s a technology “solution” that makes the camera almost useless in many shooting situations.
