I have two lenses at the moment, a sigma 70-300mm and a nikkor 18-135mm lens. I dont know if I should get another lens or if those two are enough for what I need. If I was to get another lens, I would want one with a much shorter focal length, possibly a fixed focal length macro lens, but im on a limited budget and dont know what to buy. I take photos of pretty much anything that I think would make a good photo, whether its a close up of a flower, or a landscape. The problem with SLR's there is no such thing as a "one lens suits all" lens.
