Best budget lens for the sony a6700?
For a budget pick on the a6700, I'd start with the slower Sony zooms. My go-to is the Sony E 18-55mm f/3.5-5.6 OSS. It covers everyday shooting, from wide scenes to portraits, and the optical stabilisation helps when light is low. If you want a little more reach, the Sony E 18-200mm f/3.5-6.3 OSS does almost everything in one lens, though it's a compromise on sharpness at the long end.
Keep in mind that a good lens matters more than a flagship body, so splitting your budget between the camera and a lens is worth doing. For the full range of options, see the Sony a6700 page.
