Hello,


I was wondering how you define the quality of the Bokeh. How does it have to be to be "good"?
And why do different lenses have different bokehs. What is the connection there?


Another question to that matter:


I shoot a bit of macro recently and it is really hard to find the right f number to get the point of interest sharp and everything else blurred. Is the doF just dependent on the distance to the object and the f number or does it depend on the lens as well. In short, do different lenses with the same distance to the object and the same f number differ in the doF?

Thank you!
