 @Caefix:Thanks for showing me how I can check if a camera supports aperture priority with CHDK

@waterwingz: Even if a camera with the original firmware has the option of aperture priority, it may happen that when installing CHDK the option "Override Aperture" is not in the menu. I think this is the case of my previous PowerShot S110 camera.

CHDK for the S110 supports "Override Aperture" (as it does for the S80,S90, S95, and S100).

EDIT :  and clearly my previous explanation about Maximum Aperture specifications isn't sufficient when the vendors' camera spec bizarrely omits that it has an actual adjustable aperture

If a camera physically has an adjustable aperture, but does not show aperture override options in the CHDK menu, this is a bug in the port which should be reported and fixed. This is a property of the CHDK build, not a problem with installation.

This has certainly happened in the past, but IMO most if not all current ports in the official autobuilds are correct, since we can generally tell which hardware is present from the firmware (discussed in https://chdk.setepontos.com/index.php?topic=13228.msg137629#msg137629)

The SX620 has the ND related tasks and not the iris ones, so is almost certainly correctly defined as an ND only cam.

Don't forget what the H stands for.
