Hi guys and especially Klaus ......
Recently there has been a thread on DPR Nikon MLCs about busy background bokeh with Nikon tele-photo lenses ...... all sorts of theories were put forward including modern exotic glass elements etc ..... my theory was nisen bokeh.
(the splitting of OOF subjects such as multiple grass etc where the hard edges all jumble together to form ugly irregular backgrounds)
It's there on the Tamron G2 150-600mm, the AF-S 600mm F4E FL which are both modern designs, but also equally on the older AF-S 500 F4D which must be nudging 20 years old and has I think only one ED element.
The latest Z tele-photos also seem to have it in just the same way.
The million dollar question is why is it happening ..... and is it possible to design tele-photo lenses that can get round the issue?
I've looked all over the web and have never found an answer to this question.
thanks in advance ....
