I was given a Nikon N55 that came with two what I guess are telescoping lenses. One says Nikon AF NIKKOR 28-80mm 1:3.3-5.6G the other is alot bigger and says Nikon AF NIKKOR 70-300mm 1:4-5.6G. Also recieved several filters that I have no idea what they are for. Would love to learn how to use my camera and eventualy the lenses and filters. I just found the switch on the side that changes from automatic focus to manual, now it would be nice to figure out what the wheel on the top left of the camera does. I know that the icon of a silouette means a portrait and the mountain icon means taking far away pics(?) Any help greatly appreciated
