7d Auto-power off question (1 Viewer)

Just an add-on to the problem with my 7D which continues to 'go to sleep/freeze after a short time.

In the functions/menu is "auto-power off" which was (factory) set to 1 minute. Can anyone tell me
If this is correct ?
Is your 7D also set to 1 minute? If not what is/should it be set to ?
Is this just a 7D setting? (never noticed it on the 40D which I no longer have
so cannot check)

Thanks

Not sure if 1 minute is the factory set option but I think it could be. You can set it to whatever you like, there is no right or wrong setting. If you set it to say, 1 minute, all it means is that after 1 minute you will have to half press the shutter to wake the Camera up - no big deal either way.

BTW it is exactly the same choices on the 40D so you could not have looked very hard David ;)

I guess the reason for it being there is to save Battery power.
 
1 minute is the default starting value IIRC.

As I've suggested elsethread, I don't use auto power-off at all, and haven't since my 30D days, because the batteries last, and - especially with two batteries in the grip - there's not a snowball in Hell's chance of running out of juice before being able to get back to my charger.

Switch it off, sez I...

You are quite correct sir-I didn't look very hard (didn't look at all actually:-O).

I have changed the setting to 15 minutes and (toes crossed) it hasn't happened this afternoon. I'm inclinded to switch it off completely but "it must be there for a purpose":h?:

Depends on your shooting style and whether or not you always switch the camera off. My computer desk overlooks my feeders and I often leave the camera switched on all day just in case something interesting comes along. As an experiment yesterday I switched off the auto power off and left the camera switched on - by this morning the battery was absolutely drained (only one battery). So one big advantage to using a auto power off is that if you inadvertently leave the Camera switched you will never drain the battery, indeed you need never switch the Camera on/off if you use a auto off - I have heard of loads of people that do this. Like I said previously there is no right or wrong setting!!!! but I will certainly be leaving a auto power off set.

Fair comment Roy.

It does strike me though, that whether the camera is in auto off or actually off, we still have to activate a camera control in order to fire it back up again (either the shutter button or the on/off switch), and - given the instant start-up that most cameras have these days - there's no downside to disabling auto-off and actually turning the body off properly if it's going to be standing idle for a while, because it will be on again just as quickly either way.

Then again, I've never forgotten to properly turn off my camera when I'm done - I realise that if this is a possibility, auto-off has that advantage.

That sounds like a young persons disease ... I forget all the time !

I used 8 minutes on my 30D.

Had it set to the maximum 30 minutes on my 300D because it was so slow to start - despite the fact that it had poor battery life. It just wasn't worth waiting for ages for the camera to wake up.
