Voigtländer APO-LANTHAR 28mm F2 Aspherical (Nikon Z)

Testing on Nikon Z finds very high resolution and clarity from f/2, with well-controlled colour aberrations and coma, which makes it a good night-sky lens. Flare, glare and ghosting resistance are very good, and colours and micro-contrast are in line with the 35mm and 50mm APO-Lanthars.

The weak spots are the outer corners of full frame, which trail the rest of the image, strong light fall-off wide open, and focus breathing of around 8% from infinity to close focus, which is obvious in video. Bokeh is pleasant but not as smooth as the 35mm APO's.

Owners who already use the 35mm or 50mm APO-Lanthar on Z bodies describe it as the wide companion they were waiting for, praising the compact size, the smooth damped helicoid and how little post-processing the files need.

Common complaints are the price relative to autofocus 28mm primes, the need to correct vignetting, the lack of weather sealing and a de-click option, and a focus throw that is long for quick zone focusing.
