I have recently bought a Nikon D5100 with a 18-55mm and a 55-200mm kit lens. Now I am planning to travel to Japan (next April) and I would like to buy a new lens now in order to practice before leaving for the trip.
Some of my colleagues suggest a wide angle lens, and others suggest the 50mm lens. I would also be more oriented for the Nikon 50mm 1:1.8G since it can shoot great photos with low light conditions and make also very good Portrait with blur background.
In Japan I would like to shoot a lot of details on the streets and people, more that portraits however.
Is the 50mm a good lens for this kind of photography or would you suggest something else? I have seen the 50mm 1:1.8G is out of stock in many shops (Amazon, Pixmania, etc). I live in Switzerland, does anyone know of other reliable web sites for photo lenses?
