hi , there is no lens so call must have lens it u who decide what u like to shoot than decide wat lens u need to get ...
landscape = fisheye / wideangle like 10-20mm or 12-24mm range
street = 17-55mm , 24-70mm some even like to use 70-200mm range
zoo = 70-200mm and above
bird = 400mm and above
macro shoot like flower / insect = range from
60mm macro to 200mm macro
so ask yourself wat u need or u can get 18-200mm for tryout than see which range u use most or u find it more useful to u
