Don't they switch off "auto ISO", automatically, in manual?

In Auto and idiot modes, AutoISO can cover 100-1600 automatically. When you switch to M or the creative modes, it doesn't disable AutoISO. Instead, it limits it to 400-800 ISO. Which is just brain dead.

Give me the option to switch it all the way on, or all the way off. This kinda-on setting is useless. When I'm in Av, I don't want to bother with ISO. I want to camera to set the right ISO to get a fast enough shutter for a stable shot, be it 100 or 1600. Having to fiddle with ISO in Av mode slows me down and defeats the purpose of using Av in the first place.
 
Can you guys elaborate on this? What does this mean? If I shoot in Av, does it mean the camera sets the ISO (AutoISO) from 400-800? Does this mean you can only really control it when you're shooting in manual mode or something or am I misunderstanding?

You can set ISO manually in any of the creative modes. That's not an issue. I don't know about the idiot modes, I haven't tried.

It's Auto ISO that gets crippled depending on the mode.

I think he's asking you about the 40D - not the Rebels.

AFAIK on the 400D the Auto ISO is confined to the idiot modes (where imo it belongs). While I'm sure having the camera think for you is convenient I've yet to find doing it manually inconvenient.
Just thought I'd upload a full res pic, as shot, from the cam.
I wondered why you uploaded it to google - would getting a similar result from RAW be too difficult?

You should have the choice. On the 1D models you have. And several other brand cam I've tried.

Different strokes for different folks. I find myself in enough situations where getting the shot is more important than getting the ISO I prefer.

Do you regularly miss the shot then because you're adjusting the ISO?
 
Changing ISO on the 40d is just as easy (and fast) as adjusting the shutter speed or f-stop. You just press the ISO button (which is right next to the shutter button) and turn the top wheel (advantage of having the ISO displayed in the view finder).

WRT colour management in the browser, I must be honest and say I can see no difference in colours between pics displayed in IE7 and FF3 with the colour management installed. I have a feeling this is due to the difference in the way colour management is handled between Win and Mac.

That would be handy - I regularly switch off the LCD (for various reasons) and what the ISO was last set at could be anyone's guess :)

EDIT - Get a Mac :p

No but one of two things happen often enough that shouldn't:

1. Too low ISO (stuck at 800) so the shutter speed goes too low for a stable shot in Av.
2. Underexposed shot in M because shutter is as slow as I can for the shot and lens is wide open.

To get around this I often just leave the camera on 1600 or even 3200 ISO if I know I'm going to be shooting in challenging Now if Auto ISO did what it's supposed to, that wouldn't have to happen.

No, it's slower, because you have to press a button first. It's also slower because now you have to fiddle with two settings instead of one, and you can't adjust them at the same time. Not a problem for taking pictures of stationary things, but when you're trying to catch something in the action, it's a different matter.

It's in the viewfinder and on the top screen. Which is why the prospect of Auto ISO getting it wrong doesn't bother me so much. If it sets it to something I won't approve of, I'll know.
 
Remember film and having to change it if you wanted a different ISO? After that pushing a button doesnt seem like too much of a schlep to me. :)

True. Doesn't make it right to cripple a function of the camera though.

:confused: I have no idea what you mean here. You're only changing one value. For me changing the ISO is faster than changing the aperture in manual mode as the back wheel is under my nose (left-eye viewer).

Most of my shots of of living, moving things :p
 
Like I said before. Different strokes for different folks. I *want* a working Auto ISO in creative modes, and there is no excuse for Canon's pathetic implementation. It's something they can easily fix with a firmware update, and they should.

They wont. If it's that important you might consider an upgrade to the 50D - that's what Canon wants you to do.
 
Let me rephrase my position on it. I consider the Auto ISO limitation a bug. A mistake. They should fix it.
