The D80 has three AF modes and I always select AF-C for moving objects. With this the servo is continually refocusing on the object although the speed at which it does this is lens dependent. With the AF-S series of lens the auto focus is incredibly fast but the 80-400mm lens is much slower. It locked onto the bird because it was travelling tangentially to me but I doubt it would have kept up if it had been flying towards me. The others lenses I have would have had no problem - all are much faster indeed. bones -----Original Message----- From: jhb-bounce@xxxxxxxxxxxxx [mailto:jhb-bounce@xxxxxxxxxxxxx] On Behalf Of franklyn fisher Sent: 15 July 2007 11:13 To: jhb@xxxxxxxxxxxxx Subject: [jhb] Re: Another OT Thanks Bones That cleared that mystery, thought my camera was nackered, only just found the histergram by accident. I think I need to talk to someone who is familiar with DSLR's and can run through the options and how to use them, a camera club is indicated. Your shot of the gull, was fantastic, only just beginning to appreciate just how fast my camera can start up and shoot, compared with the old Konica. I took some shots of gulls and cormorants whilst doing the trip around SF bay, but they did not come very close. Frank
