Re: FM Review of the Voigtlander 40mm f/1.2 Nokton
I just tried a Nikon No.5 T closeup lens on the Nokton, and it does some magic. MFD is not much shorter, something like ~0.3 meters. But at the same magnification as without the closeup lens, sharpness is extremely much better. Probably because you're at a few meters according to the Noktons distance scale.
The No.5 T is only +1.5 diopters and made for the Nikkor 105/1.8 (62 mm filter thread), so it doesn't do very much on such a short focal length as 40 mm. But it's apochromatic and allows you to use the lens from ~0.3 to 0.7 meters with lesser haze and still get the same bokeh quality.
