Ok I have a D300 and the Tok 10-17mm which I quite like. Trouble is a buddy highlighted a flaw with the excellent 10-17mm - its not great in temperate regions in low viz where you need to open her up. It suffers from purple fringing. I have the Sigma 15mm which is a great lens but not as wide as the Nikon 10.5mm. What do you folks use in temperate regions?
Also for macro I have the Nikon 60mm D, where should I go next? The Nikon 85mm or 105mm?
cheers
