Hi I am looking either of these lenses this coming December. I hope to get it in a cheaper price as I am really on a tight budget and just a hobbyist. My camera body is: Nikon D3400
Sigma 17-50/2.8 EX DC OS HSM
Sigma 17-70/2.8-4 OS "Contemporary ---1st choice.
I am also selling my kit as I am in need of extra funds for the lenses mentioned above:
Nikon AF-P 18-55mm VR
Yongnuo 50mm 1.8G for Nikon
