Yes the curtain seems to be in focus & yes this has been the problem for quite a few photographs now. Everything except the subject was in focus & it did not make any difference whether aperture was wide open or pin hole.
Today i changed the AF Mode to Single Point Viewfinder & Metering to Matrix Metering & i think that the photos have changed a little bit & now the subject is in focus (i'm not sure).
Do you get anything from what i told you. If yes please tell me & help me.
@jpFoto......Will Under exposure make the difference?
