The Voigtlander Nokton 58mm f/1.4 II is an interesting new offer in the standard lens arena. The slightly longer than average focal length is especially attractive for APS-C DSLR users - a field-of-view "equivalent" to "85mm" is pretty much in the sweet spot of portrait photography. Technically the lens is somewhat soft at f/1.4 both in terms of border resolution as well as overall contrast. At f/2 and more so at f/2.8 the quality has improved significantly and the quality of the bokeh is also best around these settings. The sheer resolution potential in unleashed at medium aperture settings where the lens is about as good as it gets today.
The level of distortions is negligible in field conditions and lateral CAs as well as vignetting are not much of an issue either. The lens is absolutely beautifully crafted and a joy to use despite the lack of AF. Unfortunately the constant overexposure of 2/3EV is a bit of a faux-pas although it's something you can deal with.
The lens is attractively priced at around 330US$/€ so if you've got a soft spot for a more classical approach to photography (count me in ...) it may be reason enough to favor it over the AF Nikkors and it's a viable alternative to the Zeiss T* ZF 50mm f/1.4. It is not a superior option though.
