target for my Nikon D300?
I need some advice about what I should get glasses. I am a serious amateur-young-photographer and love taking pictures People and culture, i love unfeigned portrait and photography, and oh, also street photography, pi has a Nikkor 17-200 and still no idea than the lens I get to the side, a lens that works best for all my needs above. Can any of you give me a suggestion? thanks
I have the Nikkor 70-200mm 2.8 of the opening with VR (vibration reduction) and impressive. It is a telephoto lens can bring handheld pictures in low light. images look much better than my cheaper lenses.
