Hi - Ive bought an olympus XA and XA2...Ive tested the Xa and it seems to work as it should. However, with the XA2, regarldess of film asa, available light or which zone settings I use, the second click is about 1.5 seconds after the first. Am I right in thinking the second click is the lens closing. If this is the case, then there's no difference between each exposure from what I can hear and all exposures will be overexposed. Or, is this how it's meant to be? Many thanks.
