Re: Panasonic DFD

Here's an article explaining DfD technology. A key quote:

Of course, given that the camera needs to understand each lens' bokeh characteristics in great detail, the first question we asked was what will happen as Panasonic develops and releases new lenses: Will the GH4's firmware have to be updated every time a new lens comes out? The answer was that, while the GH4 will contain a database of all the current Lumix lenses, new models will have their bokeh profiles stored on internal memory in the lens itself. So, no camera firmware updates needed, each new lens will carry with it the information needed to make DFD work.

This naturally leads to the next question: What about third-party lenses? As you might expect, the GH4 doesn't contain a bokeh database for every non-Lumix lens out there, so third-party lenses will revert to Panasonic's (already very fast) conventional contrast-detect AF algorithms.

Cheers,

Rick
