No, it is not speculations that the camera uses enhanced live view.
It is official from John Carson in an interview in Amateur photographer.
It is also not speculation that Pentax has "revised" the lenses - no changes in optics, but internal changes to work with the new functionality in the new camera.
It is also not speculations that contrast detect AF needs update to lenses, they are requiring it for the 4/3 system. Why would Pentax be different?! And Pentax has an older mount than the modern mount in 4/3...
Quote: I have some difficulties believing that Pentax designed a whole new system (new body + lenses mechanisms) with superior AF technology than C&N in 6 months...
It is not a whole new system.
It is a different body design, but that doesn't have to take several years to make.
Basic electronics and stuff were already designed, for the "K20D replacement".
The lens mechanism isn't completely new, it is just an update to the existing one in the SDM lenses. Consumer lenses will be SDM, it is not something they came up with just now, they have planned it ever since the K10D got power contacts. Remember, optical design the same - so most are already there. It will of course to take time to roll out a completely new set of SDM lenses, that won't happen overnight.
But releasing a new camera with an update to the 17-70 SDM that already has SDM, and then follow it with more SDM. Not a hard thing to do really.
Olympus offers updates to their newest lenses, users can take their lens to Olympus and Olympus updates it, to work with contrast detect AF.
Doesn't sound like a very big thing to do that takes several years to develop... Olympus released this update just a few weeks after the Panasonic G1 was official.
It is just updating of existing technology, nothing completely new.
And contrast detect live AF as been around for years, nothing new there too.
The "K20D replacement" where already prepared for enhanced live view.
The new thing is that it is coming down in a smaller package.
So it is definately not a completely new camera. It is "just" a modification of the "K20D replacement". Not a totally new camera, just a modification of a prototype still in development.
What is "superior" to Canon and Nikon (your words, not mine, I have not said "superior") is that Pentax does this update to enhance the functionality and speed of contrast detect AF. Without this, the lenses would be too slow - like it is on Canon and Nikon. It is perfectly possible for Canon and Nikon to update their lenses too, and they may just do that in the near future. Not a big thing, not a hard thing, nothing revolutionary about it.
Thing is, contrast detect AF is a compromise on Nikon and Canon because their lenses isn't updated to take advantage of the new system. Those updates are surely to come soon.
