I only have one tripod, a Velbon CF640. It goes with me, packed in my suitcase. I need it for the Bigma, and can't afford the luxury of two tripods. You do have to check them - airport security sees them as a potential weapon, but tbh I'd rather check it, as I have enough to cope with with my photo back pack as hand luggage. I would have to take the tripod of the back pack every time I wanted something from it.

Does anyone know of a cheapo ball head which is compatible with the Arca-Swiss system?

I want to get a monopod. I currently have a ball head (from Markins) on my tripod and use an Arca-Swiss type QR plate on the camera and Bigma.
I don't want to keep moving the ball head from the tripod to the monopod - tough in any case since it is Loctited in place.

So if I buy a monopod I will have to fork out on another ball head. If I have to get another Markins or similar the price puts other things I'd like to buy firmly on the back burner, given the cost, and makes it hard to justify buying a monopod even.

I could use another system and keep changing QR plates but they too are firmly attached to camera and lens now (though not with Loctite!) and I'd rather not have to keep changing them and risk losing a QR plate, especially given the price of the two I have .

Why on earth would the police want to falsify the details from a speed camera? Do you have any idea how many photos they would have to change - and how many times people could, and would then challenge such a photo - it would be easy to prove you were elsewhere at the time the photo was allegedly made, just as Karl is now trying to do. Seems a totally pointless thing to do.

I have flown with mine quite a lot. No problems at all. They don't even take it out of the bag at security like they often do with laptops.
You cannot take a tripod or monopod as hand baggage though.
Had no problems snapping in the airport either.

Yes.
Keep the old file safe just in case but it should work.

Tel,
you just update the camera RAW version to the newest one, and replace the file in PS. It tells you in the instruction clearly how to do it.
I did it for PSE6 when I got my K20D.

Lightroom and PSE 7 are also updated.

I am not surprised there is no up date for earlier Photoshops tbh - they are in the business of selling software after all.

In the past we have had to wait a few months for the update so it is good to see that it is ready before the camera is for a change.

Edit:comment added.

Now you can find out what you did wrong

The K-7 manual is up on Ned Bunnel's blog. Note he says it will be shipping in the US mid July.

Adobe have already got an update for Lightroom and Camera RAW
