While I'm in favour of IS, I've just read from another poster that IS can affect bokeh
while I've put a parallel question in the relevant post but it seemed right to put the question here also - is this correct?
If the IS elements are so decentered at the moment of the shot, to affect the bokeh, this means that without IS, you whole shot would be bokeh only.
Not to mention that you can always turn the IS off.
On the other hand, the IS poses design restrictions, and they might affect the bokeh.
