K5 II AF module on K5, is it possible?
Is it possible to retrofit the new AF module on K5? Does it worth the expenses?-- hide signature --
It's the singer not the song.
Not possible, this is not only the AF module itself (which is bigger) but you also need to have different circuitry + different firmware. This is not like swapping exhaust in old car. Cameras are not that modular like PC computers, where you can change graphic card and after driver installation everything works. Cameras are much more complex products.
