There are also these.

Look in the menu, the key word is collapsible

The two smaller ones are available with white on one side and black on the other.
That might be all you need maybe?
If you need some more you can use a small flash with a colour gell to colour the white side

I wouldn't go for grey, it looks quite dull most of the time i think.

Why not?
DNG and pef of the newer camera's are roughly the same size.
i'll probably shoot in DNG when i get the K5 because the format is wider support.

Thank you Flosie.
Will probaly shoot in M-mode anyway because i don't think the camera would be able to meter everything that's happening so better to keep it all under my controll.

I was thinking of using the DA*16-50 for the whole group shots and the DA*50-135 for the close-ups but i think i'll just go for the close-ups.
I also want to enjoy the concert while i'm busy you see

Boudou I didn't knew it would do that

If it's expressed in degrees it's actually Angle Of View (AOV) Field of view is measured in distance (metres, feet).

Here is a nice tool to compare focal lengths.

Sorry Ross i just see that you've a KX and indeed you need to set the green button to function like that.
With the K10D for example you've the optical preview on a dictated button so the Green button is actually fixed on the setting i explained.

The optical preview can be very handy with landscapes so that you can precisely place the depth of field or with product photography for the rest i at least have hardly used the optical preview for something else.
I think the green button with the exposure function is indeed handier.

Yes of course but don't know how much further i can explain, it might be better if someone else worded it differently but i'll give a try.

You can set different type of programs under the green button in M-mode.
-Av shift (shifts/moves the f-number / short off Tv mode)
-Tv shift (shifts/moves the shutter-speed / short off Av mode)
-MTF (moves both aperture and shutter to get the best photo / sort off green mode)

When you press the Green button in M-mode the camera takes a quick metering and adjust the settings following the rules of the program you've set.
It does that just for the moment you press the button so it doesn't adjust/update the settings all the time.

This can be very handy when you want to consistency of M-mode (same settings for several photos, handy if you want to batch process photos) but want to convenience you get from the automatic modes.

Ah okay.
The problem might be that it is very hard to judge the depth of the ornament in the photo.
So your mind is trying to make from a 2D photo a 3D image in your head but isn't capable to do so since it's being fooled.

You can blame the perspective if you want

Don't be fooled by the class rating too much, class 10 is quite a new standard so not many cards use them.
So a class 6 card from slightly older generation can actually be faster then a class 10 card.

But here comes the the thing.
In Av mode like you said shutter speed is updated automatically, so if you want a precise shutter-speed you need to use the dial to set it on Tv or you need to lock the exposure.
When you want a certain shutter speed in P-mode you just dial it to that figure, you want a certain f-number just dial it to that. The camera won't try to update the number you change but will change the rest.

Actually that's what you're doing with P but you're taking out the handling of turn the mode dial to the mode you want.

It's just what you're used to really, non is better then another.

I for one, really like the green button in M mode.
I've set the green button up like an Av on demand, so with one press of a button you can get the exposure settings really close to the correct exposure.
When you use spot metering you can even be more selective on what you meter and if you do it correctly you can speed things up when shooting manually.
