Originally posted by Asha Don't see how FOV is an exception, by the way. How can it be an exception when all the astronomers and optics professionals use FOV, but only in photography it is something else?
Yes it is, i clearly said that photography is the sole exception to this.
It's because like you say often it's the angular that's important but because with photography you also have a clearly defined focus distance it makes it posiable you can calculate the height of the field that is focus for example.
You can probably figure out yourself why that might be important for photography.
For astronomy and for biology this is of no interests at all and so no clear diffiration is make because it's never used while with photography both are actually used in practice and so we use AOV for angular and FOV for dimension just to make our speech clear.
You don't have to agree with this but this is how it is though, so if you use FOV for angular on photography discussion you know where the confusion might come from.
