    take the number= 1mins
    wait for your turn= 15mins
    talk the front desk person= 2mins
    fill in your camera and your personal particular= 2mins
    sensor clearing=5mins

    base on my experience on visiting Nikon service center, people there are very efficient, the prolong waiting time is because for some strange reasons, always have someone just before your turn will ask the front desk person many many questions, to make those behind the Q have to wait .................................................. ...................................

    no, difinately is dust spots on you sencer, but it show as a ring shape due to mirror lens, remember the mirror lens turns all the highlights into a ring? that's the character of mirror lens.

    Alas got my ccd sensor clean at Nikon Serv Ctr today FOC still under warranty if w/o warranty sgp26 incl 5% gst. After service ask to go out try a few shot to test but nothing much to see due to screen to small. Best thing give calander and key chain service.
    Need to go home and shoot shoot .... then blow up and check check ... hope everything is fine.
