Wouldn't an APS-C camera require some adjustment to this rule of thumb? I thought that any given F-stop on a 35mm would be one stop faster than the equivalent aperture on APS-C.
No. A given ISO, f-stop, and shutter speed should yield the exact same exposure regardless of sensor size (or focal length). Of course, if the FOV is different between camera/lens systems, that will affect the metering, but that difference could go either way. Assuming we're metering off a fixed controlled target, exposure will be the same on any camera, any lens.

Not for exposure. The one stop comment is on the effective depth of field.
Good to know, thanks.
