من تو نظر یکی از کاربران Dpreview متوجه این شدم که اگه از حالت Liveview استفاده بشه برای هر عکس سه شات حساب میشه.حرکت نا امید کننده ای بود
The shutter count should agree with the file number (up to the point that the file number starts over) as long as you have never used Live View, or edited NEF to jpeg in the cmaera. Live view without shooting any still images adds one to the shutter count. If you take pictures (stills not movies) while in Live View the count nearly doubles (3 for one image, 5 for 2, etc.).
