How bizzare !!! When I first shot raw PEF with the K10D I am sure I could not process the files. I have just tried after reading your comments, and I can ?

Either I cocked up when I first got the camera, or it was something to do with the firmware update.

Either way, thank you for your help.

I have just moved from a DS to a K10D. I do my pp in Photoshop Elements 4.0.

With my DS I shot raw in PEF and used Adobe Camera Raw 3.7 processed in PSE 4.0

With the K10D, as I have not upgraded PSE to 5.0, I cannot use a later version of ACR so cannot shoot the PEF format, as ACR 3.7 does not support the K10D .PEF

Of course I can shoot in DNG directly and this is what I have been doing. My question is therefore ..am I missing out on something because I am using a version of ACR which does not recognise my camera ?

When I first used ACR with my DS , when I opened a PEF file there were settings labeled "default camera settings". When I use A DNG file from my K10D these "default camera settings" are the same as they were with the DS....is this because the ACR does not recognise the K10D.

So should I upgrade to PSE 5.0 and install the latest ACR 4.1 ??

Any help appreciated.

Have you tried fitting a DS screen to the K10D? Solved the problem for me with K and M lenses, while leaving exposure with A;FA;DA etc unaltered.

I certainly wasnt intending to lynch you either, and I am sorry if I gave that impression. It was meant as a serious question though, as I understand that digital sensors are far more susceptible to stray light ruining a shot than film is.

I know it is too easy to get paranoid about things like this, and maybe that in most situations you would not notice the difference between these filters and a Hoya multicoated for example....but where you are putting something between the subject and the sensor, I would always go for the most reputable manufacturer that you can afford.

Would you put a new lens from an unbranded manufacturer that cost you £20 on your brand new pentax camera ????

I had read on DPR Pentax forum that the DS screen would solve the exposure issue on the K10. After experimenting with my K10D for a few days and noticing the overexposure with my K + M lenses I put the DS screen in. Immediately solved the exposure problem , without affecting exposure with the FA and DA series lenses....magic !

I upgraded from a DS which I had previously fitted with a split prism screen so the DS screen was a spare. You can order the DS screen from Park Cameras and other Pentax suppliers. I also believe some of the other Pentax screens (gridline) etc will have the same affect of solving exposure on the K10D, but go to DPR forum and do a search or ask, to be sure.

I would recomend the DS screen though...no difference at all except that the K +M lenses meter correctly !!

ps. The focus screens are very easy to change.

K and M lenses dont have electrical connectors to tell the camera what aperture they are set to, so will always work in manual mode only....you set the aperture on the lens and the shutterspeed on the camera dial(or get the meter to set the shutterspeed for you). I canot see how a future camera willl get round this problem.

Av mode will allow you to take a correctly exposed picture , BUT at maximum aperture only.

The focus screen issue cannot be fixed by software , but can be fixed by using a DS screen, or i believe one of the Pentax grid screens. Do a search to find the answer.

You dont need to buy a complete set of new DA lenses. Any A;F; or FA lenses will work perfectly if you set the aperture to "A" It must be an autofocus lens for the autofocus to work of course.

You meter in manual mode the same as with the other Pentax digitals. You select the aperture you want, then press the "green" button. The camera then stops down the lens for an instant and takes a meter reading. You then can focus and take the shot. This way you are always composing and focusing through a wide-open lens.

I moved from a DS to a K10D recently and found the K10 progressively over exposes as you use a smaller aperture. Switching to a DS focus screen solves this completely without affecting exposure of the modern FA or DA lenses.

Changing the focus screen is easy, and only requires a pair of tweezers, and a blower to ensure you remove any dust specs from the screen and screen area before you fit it.

Congratulations to the winner and all the entrants.
