Most of the time for me too Mike. I was sure I'd seen something similar and just searched the forum for 'bright spot'. It didn't take too long.

Now . . . what was I doing . . .

Found the thread I was thinking of here.

The OP's images have gone but there is close up of the 'bright spot' part way down the thread.

I think I've seen this problem before on here but can't find it now.

Where did you get the camera?

If it's lasted only a few weeks, did the supplier give any kind of warranty?

So, you hate it then. Want your money back?

I offer 24 month returns policy on FA 135mm lenses if not totally satisfied (less postage of course), and your in luck, it hasn't expired yet.

That's about the only lens I regret selling. That, and the K50/1.2 . . . and the FA 100mm/2.8 Macro (now replaced) . . . and the A24/2.8 . . . and the K500

I think we should draw a line under this now.

The line is drawn.

BEWARE:

Microsoft's past history has shown that only every other release of their Windows OS has proved to be stable/usable.

Windows 3.0, NT 3.x, Windows 95, Windows ME, and Windows Vista were less than perfect.

Windows 3.11 for Workgroups, NT4, Windows 2000, Windows XP, and Windows 7 were/are reasonably robust.

If Windows 8 exhibits this historical tendancy, I'll wait for Windows 9 with service pack 1.

Windows 7 Home Premium or Professional should be your preferred upgrade path, and if your PC is 5 or more years old and has 32 bit architecture, don't bother upgrading it, get a new 64 bit PC instead. Intel iCore 3, 5, or 7 CPU preferred with plenty of RAM, probably 8Gb minimum.

You can run most 32 bit software on a 64 bit platform (hardware and O/S), but you can't run 64 bit stuff on a 32 bit machine.

Windows 7 Professional will enable the use of older PC software, which might not work correctly on Win7, usingthe free Windows XP vurtual machine that can be downloaded from Microsoft.

When you have your new PC running as you want it, replace the HDD in the old machine and re-install it from scratch. Put the old HDD back into the old PC and copy everything from it into an archive folder on the new HDD or the new PC.

Follow my recommendation and you'll save yourself a serious amount of frustration.

I would hope that any PC that can be bought today running Windows 7, will be able to run Windows 8 when it's eventually released (my guess is it'll be when mum's and dad's are buying new kit for their little darlings return to school around September 2013).

No thanks.

My days of testing Beta and pre-Beta software are over. I'll wait for Windows 8 with SP1 to be available.

Good luck with it though.

They do now link.

Photoshop is dependant on Adobe Camera RAW (ACR) to process raw images. Not to miss out on profits, Adobe changes the version of ACR with each release of Photoshop. To you, that means that your version of Photoshop has a version of ACR that does not support your camera's files.

They do however, as Stefan points out, produce a free DNG RAW converter.

If your camera can save it's raw images as DNG instead of PEF, use that instead. PS CS3 should then be able to work with your images.
