I thought about that, but then it's a bit too restrictive. I prefer using manual exposure locking when needed (rarely though) - the AE-L button is in a comfortable place so it's not a big deal to press it when needed. Moreover it lets me setting the exposure locked on a different object than the focus.

Pretty much my thoughts too.

BE WARNED!
It is not "locking" AE at the same as AF, but linking the AF point into the AE system.
When you do that, it only takes the segment where the AF point is and ignores the rest.
For example, you have the metering set to "Matrix Evaluative", and you enable the custom function. Now you use centre AF point and when the camera locks a focus on the centre AF, you effectively get spot metering!
What's worse, is that if the AF system does not detect a focus lock then the metering goes back to evaluative!!!
You can prove this the following way:
1) Enable the custom function for link AF & AE
2) Disable focus-on-half-press (custom function)
3) Point at a scene with some contrast in it.
4) Hold down the AF button to do a focus lock and the metering will change!
5) Release the AF button and it'll change back.
It gets even more odd if you are using MF lenses!
I'm sure it has a use... but I've messed up the exposure on too many shots thinking that linking AF & AE was a "good idea" I only recently discovered why the metering seemed so "all over the place".
Does that answer the question??

I don't think I have ever used the AE-L button. If the metering is that fiddly I use manual.

Actually, on my K10D there are two custom settings, one is Link AF Point and AE as you say and following your advice I have turned this off.BE WARNED!

However, there is a second option: "AE-L with AF locked", this is the setting I am referring to here.

I was wondering what the general consensus was for this and if it was advisable or not. I would be using it with spot and centre weighted metring.
