Voigtlander Nokton 75mm F1.5 Aspherical

The optical design descends from Voigtländer's VM 75mm F1.5, which reviewers found reasonably sharp in the centre at f/1.5 with some glow and astigmatism toward the edges, improving clearly at f/2 and very good by f/2.8. Close-range performance is a strength, which suits head-and-shoulders portraits.

Bokeh is praised as smooth with rich colour and contrast, and the lens is regarded as a good-value alternative to larger f/1.4 85mm lenses. Lateral colour and some fringing on backlit edges are the main optical weak points noted.

Owners like how small and light it is for a fast short telephoto and describe the colour and contrast as rich. Many use it for portraits and event candids where an 85mm f/1.4 would be bulky.

Common complaints are the 0.55m minimum focus, softness at f/1.5 in the corners, and the difficulty of nailing focus wide open on moving subjects without autofocus.
