I'm a beginner in photography. I'm interested in wildlife photography primarily. I just bought a Nikon D90 and three lenses on eBay. The
lenses include Nikon 18-105 AFS DX, Tamron 18-200 LD XR Dll Aspherical, And Sigma 70-300mm APO DG Macro. Will these lenses be enough for me to take good wildlife pictures? Also regarding the Sigma lens will it perform good as a telephoto lens?
