Panasonic soon releases the new 15mm prime lens which I really want to buy if the video AF performance on the AF100 is as good as with the 12-35mm (would love to have that speed and accuracy with 1.7 aperture). But any ideas what happens when new lenses are released from now on? It seems to me that Panasonic has more or less stopped supporting the AF100. I am sure it will in some degree be compatible since it is a MFT lens, but unsure if it will work as good as it should with no new firmware for it on the AF100. But I might be wrong here.... Is the lens firmware identical for all the cameras so it should work well across all cameras new and old?
