which is not as well compressed as Adobe created DNG. So for best
compression, create PEFs in camera then convert to DNG when importing
into Lightroom or ACR.
what is ACR? just curious. If all you are saying is that PEF takes up
more room than a DNG it doesn't matter. I'm not a big volume shooter at
this stage.

ACR is Adobe Camera Raw. It's a program Adobe supplies with PhotoShop &
Lightroom that prepares your raw file to be opened by PhotoShop,
Elements or Lightroom. ACR is periodically updated to add support for
the raw file of newer cameras as they come out.
Versions of ACR are specific to the version of PhotoShop, Elements or
Lightroom you have, so when Adobe comes out with a new version of the
program, the version of ACR that matches older versions are no longer
updated.

"The Camera Raw 6.3 plug-in is not compatible with versions of Photoshop
Elements earlier than Photoshop Elements 9.0, or versions of Premiere
Elements earlier than 9.0."
"The latest version of the Camera Raw plug-in available for Photoshop
Elements 5.0 (Windows) is Camera Raw 4.5."
But I don't think it will be a problem for K5 DNG files.
