Thanks i couldn't see how to change anything but the ISO/set in P mode.. * button is the answer.
Try changing the exposure comp dial.
I think you misunderstand. In P mode, I may want to reduce the speed but increase the aperture or vice versa. EC isn't what I want.
Aren't you missing the point of P mode? Is this not meant to be automatically selecting these options for you?
The technical term is called "Program Shift". The relative exposure remains the same, but you adjust your shutter speed or aperture as needed for special situations. For example 1/15 f5.6, 1/30 f4.0, and 1/60 f2.8 would all give the same exposure. "P" mode may pick one of those three combinations, but program shift allows you to switch to one of the other possible combinations as needed.
On the M3 you need to press the * button to get it to stay on. This is before or after the shutter 1/2 press. The M5 appears to work the same.
There you go. I didn't realise that this was a thing. It makes sense that you would need to have exposure lock enabled I think.
Though you don't have to on most other brands. Another way to look at Program Shift is that it's a way of influencing the behaviour of program mode, giving it a shove in the direction of, for example, choosing higher shutter speeds than it would normally do, whilst keeping overall exposure the same. This can also be useful when done dynamically, with the metering still "live".
