D 60 Battery Drain??

[mpross]

Have had my D 60 for over a year and have only had this problem recently. Up until I got a Canon 70-200 2.8L IS I would always leave the camera in my bag without a lens and the dust cap on. Since I have this new lens, (and a new bag in order to hold it all) I have been leaving the 70-200 on the camera with camera switched off. Twice now after having left it in the case for about a week, both batteries are completely drained. Oh, yea, I have the battery grip on the camera as well, but I have always had it this way.

Will Canon's 70-200 2.8L IS drain batteries if left attached to the body???
Anyone else had this??

That sounds like a case of "old battery". That is the way that lithium ion batteries act if they have been recharged too many times or else incorrectly charged too many times.

I would replace one battery and see how that goes.

If the camera body is switched off, then it is OFF, regardless of this or that lens. So if the battery is going flat after a week, then that is "self discharge" which happens in an old battery.

I have experienced this also (with I.S. Lenses). It has been my experience that I.S. lenses remain powered EVEN WITH THE CAMERA OFF. To test this, insert the batteries into your camera with the power on the camera switched off, and the I.S. on the lens switched on. You will hear the I.S. servos in the lens move. I am going to try keeping the I.S. switch in the "OFF" position on the lens when it is not in use.

Hope that helps...

Even with the IS switch on, the IS is not activated until you press the shutter button and then it shuts itself off after 10 seconds or so. I leave IS lenses attched to my 10D and D60 all the time and have never lost battery charge.

I have found through some trial and error, that if I switch back to my IS lens and then store the camera without powering it up with the IS lens and at least depressing the shutter half way to take an exposure reading and activate the lens, it will drain my batteries in my battery grip. So now, when I switch back to my IS lens I at least power up the camera and lens, and then shut it off and my batteries are fine.
Go figure???
