My colleague recently introduced me to this kind of cool project called 100 Strangers and therefore, that's why I am here. At the moment, I have only one lens which is the Nikkor AF-S DX 18-200mm f/3.5-5.6G ED VR II. I would like some suggestions in regards to a very nice Portrait / Street Lens for my Nikon D90. I have been told of a few lenses which could do the job but since there are quite a few, I am getting a bit confused. So far, this is what I have been suggested:
1) Nikkor AF-S 50mm f/1.4G
2) Nikkor AF 50mm f/1.8D
3) Sigma 17-50mm F2.8 EX DC OS HSM
4) Tamron SP AF 17-50mm f2.8 XR Di-II VC LD Aspherical (IF)
5) Tokina AT-X 165 Pro DX AF 16-50mm f2.8
People also mentioned another Nikon lens and I can't really remember the model but that was quite expensive. And apparently, the 50mm f/1.8D is a lens that all Nikon users should have since it's a very cheap and really great lens.
Anyways, hope you guys can help me to make a decision
