Thank you all for your input, I will now make a greater effort to use this feature on my camera. Can't think why I keep ignoring it. Perhaps it's because coming from film days, I started with a K1000 in the '79, I am often distrustful of 'auto' modes such as AV, TV and P!
However, these C1 presets seem to offer a known starting point on which I can build, so meter for outside before the ceremony, then when I get out there and find the sun has gone away behind a cloud, I can flick to the preset C2 (for example, Manual, 250th, F8, 100) and then kick the iso to 200, or drop the speed.
A sort of semi automatic gear box for the camera.
Amazing what they come up with, but then given that most cameras are simply attachment devices onto which we fit an expensive lens, I guess the have to find as many USP's as they can.
