I have had my Nikon D80 and 18-135mm kit lens for 18 months. I am a full time student and semi professional photographer. I also own the Sigma 10-20mm and the Nikorr 50mm f/1.8 Recently my 18-135mm has started to fall apart, it is coming away from the body and thus occassionally not letting me press the shutter because I get the F-- error (meaning no lens attached). I feel that I have narrowed my replacement lens down to... A - Nikon 18-200mm VR B - Nikon 16-85mm VR C - Nikon 24-120mm VR I am putting all the money I can earn from photography back into lenes and am saving for a D300 so that my D80 can be a backup. In an ideal world my lens would be better quality than the 18-135, still Nikon and with VR. Any suggestions of which I should get or if there are other lenes I haven't considered?
