I know that with certain bellows attachments you lose aperature coupling and
have to figure out exposure manually accounting for the loss of light to the
bellows. But is there a bellows that allows aperature coupling? Is that what
the "Bellows A" that I recently saw advertised is? If it is not, what is the
difference between Bellows A and M? Thanks you.
