IS 1 or 2 and 3 mode

[van bogaert erik]

hello, i have the AF function set on the rear button of my camera ;

When i read the manual "Mode 1 IS" and mode 2 is the IS always on when i press the shutter button halfway .

Mode 3 is only working when i fully press the shutter button


But how the different mode's work when i AF trough the rear button i am confused ?

Can someone explain how and when the differents IS modes work when the AF is with the rear button.
Happy new year.

is the following correct ?: the rear button" af -on" has the same function as pressing the schutter button halway when selected ?

yes, if you have configured AF-ON as focus it has the same effect as half-pressing the shutter as far as IS is concerned.

ok, thank you, but when i focus and let go of the AF-on button to stop AF and take the picture , does the stabilizer stop or is the schutter button still active to start IS .??

IS remains active as long as shutter is half-pressed.

IS remains active as long as shutter is half-pressed.

ok, but then i have to press the schutter button always halfway because otherwise there will be a moment that the IS is not active when i let go the AF on button ......

solution ? : So i will place the AF back on the schutter button and the AF -on button only to stop the AF . (CFn 4-1 instead of cfn4- 2)
