The intangibles cannot be measured of course, such as "rendering", appeal of a bokeh, mechanical feel + handling and such but from the MTF graphs, the new version appears to be sharper at wider apertures whereas the CY has a slight advantage at f/11. With full electro-mechanical linkage to the digital body, the updated version has the upper hand by a good margin.
The contest seems closer when other CY lenses are assessed, such as the 2/28 or 1,4/85. In the case of the 1,4/35, the two are more clearly defined as simply different optics.
