Thanks Ian for another useful & informative article. I'll forward the link to my son inlaw who will really appreciate it & he will then discover DPNow & how good it is (being a Canon user).

Ian I emailed the Depth of Field+Bokeh to a friend who believed they HAD to buy a PRIME lens to get the soft out of focus behind ! They thought I was joking about Bokeh ! YOU just saved him 600 ! and proved me right!

Thanks everyone :)

Some lenses do produce bad bokeh and incidentally the worst offender in my collection is actually a prime, my old 50mm f/1.4 OM Zuiko :D

Modern lenses are pretty good with bokeh as long as you get close enough to the subject. I should have mentioned in the article that all lenses will produce bad bokeh if you can't blur the background enough by getting close enough to the foreground subject.
