PEF Format problems in lightroom

Just upgraded from K10 to K5.

I use Photoshop CS7 and lightroom 2-no problems with PEF format with K10.

But PEF format from K5 causing problems.

Lightroom not recognising and while I can download in Bridge photoshop not opening file.

DNG format not working either.

Any ideas- do I need to upgrade Photoshop?
Ha st ehPEF format changed?

Thanks

Roger

Get all the free upgrades to your Adobe products that are available and try again. If that doesn't work, then try shooting DNG instead of PEF or use free Adobe DNG converter to convert to DNG before importing into LR.

You need lgithroom 3 for the K5 if you want to use PEF but you can just as well use DNG though, they are the same size now with the K5 and you can use the k5 DNG in lightroom 2 en photoshop 7.
CS7 isn't out yet, i believe they want to bring out CS6 this year


And yes PEF format is changed with each camera model like every other RAW file except DNG, so you need spcial support for the camera rather then the file itself.

DNG actually changes too, which is why the free converter asks what level of compatibility you want. I notice that my LR3 created DNGs (from PEFs) will not open in the Pentax SilkyPix utility...

Isn't DNG accepted as a standard yet, i know they have send it in for approvement several years ago?
Anyway DNG uses TIFF/EP for the actual imaging part so it should always be able to read that, it's hopefully only the extra data that might be missed.

It's in the programming that Pentax had SilkyPix do. The Pentax utility will only work with camera created DNGs.

Shoot DNG. Keep it simple.
