What is a good bokeh, what should it be like? What affects it (lens, focus screen, camera settings, aperture of course).
"Lens manufacturers including Nikon, Canon, and Minolta make lenses designed with specific controls to change the rendering of the out-of-focus areas."
says wiki, and continues:
"The shape of the aperture has a great influence on the subjective quality of bokeh. When a lens is stopped down to something other than its maximum aperture size (minimum f-number), out-of-focus points are blurred into the polygonal shape of the aperture rather than perfect circles."
How about adapters? Which one's bokeh is the best? It is obvious that bokeh is not just a blur... My guess is, the focus screen is the key element to a good bokeh...
Adapter owners, could you post some images with a shallow DOF to let us compare?
Also, I'd like to see same adapter/different lens combinations. Could we build a reference topic? What do you say?
