Canon 5Dmk3 Auto ISO in P-mode Issue: I had never thought of P as a particularly useful mode until the lecturer on a Canon-backed course said he keeps his camera in it as, in...

I had never thought of P as a particularly useful mode until the lecturer on a Canon-backed course said he keeps his camera in it as, in conjunction with auto ISO, he could quickly set a speed to suit the unexpected situation and let ISO do the rest. I see his point and thought to do the same but I just can't get it! I don't seem able to select a speed above about 1/40th and ISO doesn't want to climb up either. I've checked that ISO range is not restricted and know it works fine in other modes. Am I being thick or is there an issue with this? Any help appreciated.

not really sure i can help but try setting your iso manually according to the light youre gonna shoot in, other than that, read your manual or wait for a reply from a fellow Hogger thats more qualified than me. Hope someone helps you out.

Thanks, but the point was to let the auto-ISO do the work whilst quickly changing the exposure using programme shift in P to suit the occasion, thus ensuring the full Auto camera setting (which would be the quickest alternative) didn't decide upon a speed that was too slow for the subject.

I just checked mine, I can change the ISO and f/stop

I don't shoot Canon, but do you need to set limits for auto iso and shutter speed?? Just a thought.

You must have a very proud and temperamental 5D Mk III that doesn't want to be set at P and auto ISO. :)

Seriously, you might want to check the settings in the shooting settings menu (camera picture, second tab). Select [ISO speed settings], then select [Auto ISO range]. Check what the minimum and maximum auto ISO speeds are. You might have accidentally changed the setting from the default.

If this isn't the problem, then take it into a camera store and have someone look at it.

I have checked the ISO range is not restricted - not sure whether the sped range can be restricted - will check that out. Thanks for your help, much appreciated.

I know the ISO is not restricted - got to see if the speed could be. Thanks for the suggestion.

If you're still puzzled call Canon's technical department, they are the greatest

Not quite sure what you mean Chris - is that in relation to P-setting? The idea is to change speed/aperture using programme shift and let auto-ISO find a level to suit so, say you suddenly want to catch a shot of a moving subject, where full Auto might not choose a fast enough shutter speed, by having the camera set to P mode, you can shift the combined shutter aperture setting quickly and be sure of getting a photo. Thanks for your interest in helping.

Buy this video by Blue Crane and it will tell you about your settings and how to change them. Be patient. For some people the menu system is hard to understand. For some it's easy. Have you tried pressing the Q button and selecting ISO and changing to Auto?

The way I was told is that in program you can change ISO and aperture and the camera decides what the best speed is

magnetoman Loc: Purbeck, Dorset, UK

Hi again Chris - yes, that's probably the best thing to do - I'll have a go.

ISO is set to auto, and is not restricted in range. I'm waiting for the guy who's idea I'm trying to follow, to release his video on the camera - should be out soon! Thanks for your input.

I'll go back to the manual and check that!
