The lenses have different factory numbers. Old oil has been removed from the diaphragm and other moving parts of the lens. The front and rear lens have been blackened (see video).
The best Bokeh image is at an open aperture of f/2-f/5,6 and when the distance to the photographed image is 1.2-2.5m. The background should be about 3m from the object and should be illuminated with flashes of light.It is a lens for the creative process and you need to know how to work with it.
Considering the crop factor (58mm x crop1.5=87mm), this is a simple portrait lens intended for creative photography.
