I have a D60 that has a very slow write speed. From the time I push the shutter release until it shows up on the preview screen 3to4 seconds. I have several Nikon dslrs (D200,D300s)plus a simple s3300 and all of them have faster write time. Is there anything I can do to speed that time up? I have tried 2,4,&8 gig cards but nothing changes.
