Best travel lens for the nikon d5500?
For travel on the D5500, I'd start with one zoom that covers almost everything. The travel guide makes the case for one zoom plus one small fast prime.
My pick is the Nikon AF-S DX 16-85mm f/3.5-5.6G ED VR. It runs like 24-128mm on this body, wide enough for streets and churches, and its VR helps in dim interiors. If you want something smaller and cheaper, the Nikon AF-S DX 18-55mm f/3.5-5.6G VR II is light and easy to carry. If you'd rather have one lens for everything, the Nikon AF-S DX 18-140mm f/3.5-5.6G ED VR reaches 27-210mm equivalent, but it's bigger.
For evenings and food, add the Nikon AF-S DX 35mm f/1.8G, which is roughly 52mm equivalent, small and fast.
