    the one thing you have omitted is how long have you had the lens ,was it a private sale,e/bay ,shop etc as we can advise accordingly
    Hi I bought it secondhand last year, unfortunately now out of warranty. I took the advice of another on this thread and switched off IS. It worked - no battery drain!

    Hi TonyT, it was the IS system. Many thanks for that. I wonder if a Canon repair would be worth considering?? (Which section should I have posted originally?)

    I am a bit confused here. I thought that when the camera is switched off the IS also stops working. I cannot understand how the IS could be working when the camera is switched off!

    Nat when you turn off a camera parts of it are still on, it only really stops you accidentally firing shots etc, if there is a problem with his IS not shutting off then it could be running all the time and hence draining his battery.

    You really have two choices, repair the lens
    or now you know the problem, turn the IS off when you turn the camera off, then turn it on when you turn the camera on..

    Repair costs for canon are here, https://www.canon.co.uk/images/UK%20...14-1174182.pdf although the IS is expensive and probable prohibitive for the repair of the lens, from what you say the IS appears to be working and draining the battery, so the fault may be elsewhere in the lens, it could be something simple like a shorting cable to it etc.. I would phone them up and have a talk, at least you have narrowed down the fault and they may be able to advise you further.

    Did you pay with a credit or debit card?, check, they often have extended warranties over the shop one included for free when you purchase with them.

    Hi Ferdie; when and where did you buy the lens from? Do you have any recourse to the vendor for a mis-sale and/or limited warrenty? If it's a recent purchase; I'd certainly look to the seller as a first port-of-call... Or... as tony says; if you paid with a CC you may be able to claim on a 'not fit for purpose' basis! Good luck.
    Cheers;
    Lee

    Hi Nathaniel, So am I. I just tried another posted solution which has sorted it. Before, when the camera was switched off, full battery, no usage, but IS 'on' the battery would be flat with in 24 hours!

    Ferdie it could be something as simple as a ribbon cable inside rubbing and now shorting out, or the IS unit itself, I would speak to a Canon repair centre on the phone which it have listed a couple below and talk to someone who may know and be able to advise you, it might be a known and simple, ie cheap problem to fix.

    When you turn your TV off or your Sky box it goes into standby mode, eg they still draw power and your skybox will record, same for cameras really.. think of it in standby mode.
