3D Depiction - Urban Legend or Science?
Tokyo Kogaku Topcor-S 5cm f/2 LTM chrome (V2, 1950s)
One of the design goals of this Topcor-S lens was “3D depiction”, similar to Nikon’s later "3D Hi-Fi" concept. The optical designers at Tokyo Kogaku wanted to create a smooth and slow transition from the foreground to the focus plane and then again to the background by leaving similar amount of contrast in the out-of-focus area (bokeh) as on the focus plane. This focus falloff behavior helps creating a sensation of 3-dimensionality in the space around the subject. In addition, the lens also depicts the subject in a 3D way thanks to the delicate gray tonality (shades of gray). This picture is another great example of this lens' ability to render the subject and the surrounding space in a 3D way. I forgot if it was wide open or slightly stopped down to f/2.8.
