Focus point

Was out today shooting with a Sigma 10 / 20mm lens in Manual mode, but i tried to change the focus point but it would not change from the centre of the viewfinder, anyone offer any help please.

Check your Focus Selector Lock Button. If it is set to the white dot you can move your focus point around, if it is set to L you will not be able to move your focus point.

This one
