The problem with adopting a new camera system is that lens availability tends to be a bit scarce at the start in terms of variety. This is versus long and established camera systems that have been building up their portfolio for years. This is one of the downsides to adopting the new Nikon Z mirrorless cameras, but Nikon definitely has plans to change that.
The company has recently released an updated roadmap for its Z-mount lens lineup for the next few years and it looks like photographers will have quite a few to choose from. In 2019 alone, the company plans on releasing at least six new lenses, one of which has since been announced in the form of the 14-30mm f/4 S lens. The rest of the year is also expected to see the introduction of more prime lenses like a 24mm f/1.8 S and an 85mm f/1.8 S.
