    Default How to know IS is working???

    Hi All,

    When I half press the shutter, I can hear a small click sound, signifying that IS is on... But when I move the camera after the IS activated, I dunt hear anything from the lens(as in lens adjusting due to the IS), and I see the picture in the viewfinder moves fluently(as is not really locked)....

    I even took night shots before with IS, and my pics turned up quite sharp.... Anyway to know whether IS is working or not???

    Anybody....

    Hmm.. try aiming at a edge, or corner, with IS turned off.. Then after that, switch IS on.. if there's a difference, then IS is working..

    Well, that was what i saw during SEED..

    after you half press the shutter, there will be the unlocking of the IS group in the lens. there will be (should be?) a little light vibration in your lens as the gyro sensors are working to compensate for the slightest shake. hope this helps.

    btw, check if you have Mode 1/2 first. switch to the correct mode if you have two of them...

    That's the thing.. I tried a 28-135 IS before, and it had this little vibration when I shake the camera slightly.. My version of the lens does not have this vibration... Does this mean that IS may not be working... But I still hear the unlocking of the IS group...

    I have no mode selection on that lens...
