It was referred to in the recent (02/04/13) article on Panasonic's strategic quandaries. But what is focus peaking?
Focus Peaking is a feature in Sony’s NEX and SLT cameras, ...
I had a Nikon P&S in 2001 that had focus peaking, it isn't just a recent Sony thing.
"Focus Peaking is a feature in Sony’s..."
Didn't mean to imply that it hasn't been used before (in fact, the idea comes from video cameras). But now that you bring it up, which Nikon P&S would that be?
Sony A55, Sony NEX-3, Sony F828
I don't know, it is long gone now. The implementation was much more subtle than on recent Sonys. The infocus areas were shown with a further increase in contrast to make them more obvious. Could have been the 885.
