Shutter speed and aperture are not kept when changing between manual, aperture priority (Av) and shutter priority (Tv). That is, if I
- set aperture to F8 in aperture priority,
- change to manual mode,
- set aperture to F1.2 and
- change back to aperture priority
the aperture is now F8. Is there some setting to make sure the settings are instead carried over, just as they are for ISO, white balance and others?
