    Unhappy SONY 50mm f/1.4 radical response

    I been struggling with my SONY 50mm f/1.4, that's about a year and a half old.

    To duplicate the issue, to me, seems pretty simple, yet ... I am having trouble getting the "repair facility" to do so. It has been there and back, once, so far.

    Basically it goes like this:
    1. you put the lens on the DSLR camera
    2. turn the camera on
    3. with the drive mode selection, choose Hi-speed shutter
    4. Choose "M" mode
    5. select aperture to f/10
    6. select shutter speed of 1/60
    7. select ISO = 800
    8. lift the built in flash
    9. Focus and fire roughly five consecutive shots.


    If your lens is acting like mine is ... instead of five roughly identical exposures, you will have several over-exposed ... the first one easily not right and then one of more of the rest. The problem sems to be tardy response by the aperture, itself. I do not get this response from my 17059 or any other lens, for that matter. Just this PRIME.

    I get so tired of the back and forth, with these kind of things.

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.
