Which one should I keep. I want to sell one now and save prolly for a 12-24mm lense. I have the kit lense and a 55-200 Vr. I want a good wide angle lense but cant afford it right now. So I sell one of the 2 in the title and save. Also what 12-24 lense is the best I have about $500 now but I know good ones new are around $1000. Please give me advice!
