Hello! Lately I've been trying to clean up my old stuff and when I took a good look at my lenses, I realized it's been a huge time since I havent touched my nikon 18-105. It came with my d7000 kit. Im not sure though if it's a wise choice to sell. Ill be getting $300 for it. Here are the lenses I currently own, for you guys to have an idea: sigma 17-50 f2/8: main one, all-rounder. 35mm, 50mm, 85mm primes. nikon 70-300 sigma 10-20 As I'm an amateur, I'm not sure whether I could still make good use of it in the future or not. What do you guys think?
