I've been using one of my father's old cameras for awhile now, and I'm looking to buy my own and a few lenses. I'm primarily interested in macro(flora and small animals such as insects) and landscape photography. I'm looking for some suggestions as to what equipment to buy, as it's proving to be rather difficult differentiating between the specifications that are necessary or unnecessary. I've selected a few macro lenses that I would believe to fit my needs, being the 100mm and 105mm lenses from Canon and Nikon respectively. Although I've no clue as to the differences between the two 105mm/100mm from each, or what wide angle lens/camera body to get. All input and/or suggesting are greatly appreciated Thanks in advance.
