I am satisfied that by the end of 2019, the Nikon Z system is a highly viable system in terms of high grade native optical offerings (most existing Nikon F lenses are not up to my demanding expectations). However, it would be helpful if third parties could produce lenses for Nikon Z-mount in order to accelerate that process.
The focal lengths offered by Nikon initially are problematic for me—no ultra-wide for example. While a 14-30mm f/4 solves a lot of issues, I am a bit disappointed at not seeing an 11-24mm f/4 instead—far more useful to me—the Canon 11-24mm f/4L remains one of my all-time favorite lenses for Canon, and it’s lacking for Nikon.
The choice of f/1.8 lens speed is a good one—f/1.4 just adds a huge burden of weight and size and cost that add little value—and the Nikon NIKKOR Z 58mm f/0.95 S Noct is always available for those desiring back and neck problems. I want the Nikon NIKKOR Z 58/0.95S more than any lens Nikon has ever made.
Nikon is making a lot of claims about very high lens quality for the S line, including exceptional quality control. I like the sound of that.
The title of the S-Line is reserved only for NIKKOR Z lenses that have cleared newly established standards of design principles and quality control that are even stricter than Nikon’s conventional standards.
The “S” represents the first letter of various words such as “Superior”, “Super” and “Sophisticated.” It also stands for the silver-colored line on the lens barrel: the symbol of the series.
All NIKKOR Z lenses that are released together with the new mirrorless cameras are S-Line models. Whichever model you may choose, every S-Line lens achieves new-dimensional optical performance including outstanding resolution that can keep pace with future imaging demands, providing photographers with excitement and richly satisfying shooting experiences.
