Voigtländer NOKTON 28mm F1.5 Aspherical (Nikon Z)

Early reviews describe a lens tuned for rendering rather than test-chart perfection. It is sharp at distance, softer at close and portrait ranges when wide open, and the frame edges improve noticeably by f/4 to f/5.6. Colour and contrast are good, and background blur is soft with well-formed bokeh balls.

Vignetting and chromatic aberration are clearly visible wide open, while distortion is very low and flare resistance is good. Most published testing so far covers the optically identical E-mount version.

Owners like the size, finish and focus feel, and use it as a small low-light street and travel lens, often on the Zf where its looks match the body. Many describe the f/1.5 rendering as pleasantly classic without being soft.

Some owners report weak edges when stopped down a little, and others say their copies perform well at all apertures, which points to sample variation or field curvature. Vignetting wide open, the lack of a de-click option and manual focus only are the other common caveats.
