For Macro-photography which mode is most commonly used? M (Manual) or A (aperture)?
It depends on the situation! Aperture Priority mode means that you can stop down and get better depth of field (shallow depth of field can cause focusing issues with macro) but you may need to shoot with a fairly high ISO to ensure that the shutter speed doesn't drop. If you do not have a fast shutter speed with macro photos, you can end up with blur as the slightest movement will be very obvious and spoil your images.
If you are using flash to light your subject, you do not need to worry about the ambient light quite as much and can use Manual mode to set a narrow aperture (f11, f16 or even f22) and a fast shutter speed at ISO 100 or 200.
