Best budget lens for the sony a7 ii?
For the a7 II, my pick for a budget lens is the 7Artisans AF 35mm f/1.8. It's a fast prime, so you get a shallow depth of field and decent low-light work without spending much. It's a good everyday focal length on full frame.
If you want something wider, the Samyang AF 24mm f/1.8 FE is a cheap fast option for street and interiors. For a single zoom that covers most situations, the Sony FE 28-60mm f/4-5.6 keeps things light and simple, though it's slower.
Budget a little for the lens, as the first camera guide suggests. A lens with a fast aperture will make more difference to your pictures than a bigger body. And if you buy the body used, put aside money for a new genuine battery, as covered in buying used.
