I've been into digital photography for a year now. I've been reading and learning from these forums and google. I've kinda found my nitch so to say of what I like to photograph. I don't know all the photographic jargon so if I describe something wrong forgive me ,I'm learning. Here's the question " what lenses do I need to do landscape, nature, macro and natural settings portraits?" Here's what I have ; Nikon d7000 with 18/105 kit lens, a sigma 180mm f2.8 macro and an old kiron 28/105 f3.3. Here's what I as lenses and tripod/head combo.; sigma 8/16 ,sigma 18/35 f1.8, sigma 50/150f2.8 and for a tripod I was looking at the Induro at 317 i think the largest one ( for leg length and stability) .And the BHL 3 ball head. Did.t know if that head was over kill or not. Suggestions please.
