Yes
Can anyone explain about the on/off switch on the 30d?
Above the ON mark there is a line which joins to the quick dial. If you want to use the quick dial you have to have the power switch set to this line.

So, my question is: why would you want to have it set to ON, which means you cant use the quickdial??? :thinking:
 
ah so THAT'S what its for!! Thanks. I dont think I will bother with that. I will just leave it at the top position. :thumbs:

You'll find out when you find your whole days photos were taken -/+ exposure compensation because the dial moved ;)

That's the biggest problem with it to my mind - BUT the flip side is when you have the dial locked off and then want to change aperture quickly in manual mose....grrrr!
 
Oh dear! Sounds like i will need to try both ways and see which suits me best. The separate dial for aperture changing in manual was one of my favourite difference between this and the 350d!! :lol:
 
For aperture changing in manual I doubt you'll knock it without noticing because in M you pay constant attention to the exposure.

When I am shooting in other modes I lock it purely for the reasons states - it is frustrating working to recover highlights on a number of shots because of an accident!
 
If you are a ('scuse the phrase) "noob" to photography and plan/have to use the 5 pre-programmed picture modes (portrait,sport,....) or the "green" square mode then this extra setting is no use to you.

From memory it doesnt do anything in the P (Program) mode either, which I tend to use when snapping the kids at play for the in/outlaws to look at.

When I'm being creative Av, Tv, M then the wheel comes into it's own. Especially if you get used to checking the exposure histograms after each shot. With the 30D you have the advantage that you can see all RGB separately.
 
Not just on and off then? :lol:

Are you sure? With the 20D in 'P' Mode, the wheel can be used to override the selected settings to give over or under exposure. I think it's properly referred to as Programme Override rather than Programme Shift which alters the settings while keeping the same exposure value.

It's very handy at times but it's all too easy to move it inadvertantly.
