Thanks, Karel, that's a great help! I've just done all the files I shot the other day in one go.

I can change the exif in PhotoMe, but it's a pain, as I can only do one image at a time. I know batch-editing is possible, but I need to look at each file individually to see if it was taken below 10mm.

As far as I am aware, enabling the camera to read focal length is a fixed function, which means it has been deliberately crippled not to read anything below 10mm. While trying to sell your own lenses is perfectly understandable, the best way to stop people buying the Sigma 8-16mm is to produce a comparable lens, not deliberately make it difficult to use the only existing lens of this focal length that works on your cameras.

Personally I don't see it as understandable. They should make their camera work with whatever lenses are available in their mount. Let's say they took this a step further and somehow stopped their cameras from recognising any third-party lenses (the sort of thing Apple would do). How many people would continue buying their cameras? I certainly wouldn't, and I'm sure a lot of other people feel the same way.

I am extremely disappointed and extremely p*$$"d off that Pentax/Ricoh haven't addressed this problem yet, which was also a problem on the K5. It's ridiculous that they have come out with a new camera that won't recognise the focal length on lenses that were manufactured long before they came out with this camera.

It's ridiculous that they can come out with radical new ideas like the selectable AA filter yet don't bother to make sure their camera can recognise the focal length of all available lenses. The Sigma 8-16mm is one of my most used lenses, and below 10mm I can't use DXO's excellent lens-correction profiles (as I couldn't with the K5) because the focal length is not recorded in the exif. Surely a simple firmware upgrade would fix this?

This might be useful, very cheap too! link

I've sometimes found myself trying to clone out spots on my computer screen....a couple of times I've thought the cloning tool is not working properly until I've realised.

Thanks, guys! It took a while, there's actually only 2 different stars making up all the stars in the image. A fun way to spend a rainy day, though!

The planet is a wooden ball from a pot-pourri, two of the moons came from a macro shot of a sea-shell, one was cut from the planet itself, and one is part of an abstract painting of my wife's. The stars are courtesy of the Hubble Space Telescope, from a couple of images from their free-to-use image bank.

We have just had two solid days of rain in Doha, and the roads have all been flooded due to lack of storm drains. I've been wanting to try out my new K3, so I took a trip to a neighbouring galaxy and took an image of the gas giant Pourri-B. Just a bit of fun.....

The idea of paying more for a camera because of it's paint job completely baffles me.....I thought the idea was to take pictures with them, not buy them as techno-bling.
