When the Sony Alpha 7 cameras were first released in 2013 and 2014, there was criticism about the lack of available lenses and the sparse lens roadmap that Sony presented. However over the last few years, Sony has gradually increased its range of lenses for its full-frame E-Mount cameras, and at the time of writing they have just reached the 18 lens mark, if you include the 1.4x and 2x teleconverter lenses.
