This may seem like a stupid question, but...

In manual(M) mode I can't seem to lock exposure. I read through the manual and there doesn't seem to be anything extra I need to do, yet I cannont get the * to engage so that I can lock the exposure setting? Help please?

What you need to do is lock the exposure at the point you want, then adjust the settings (shutter speed, aperture or both) to bring the line on the exposure meter into the center, then you will have the correct exposure for the point where you locked the exposure. When using the Aperture or shutter priority mode, the camera will self adjust the settings as required.

I thought in manual mode as YOU set the aperture and shutter speed there would be no exposure to lock! it wont change! I use the needle thing to judge how my exposure will come out, then take a few test shots till i get it nailed.

That is correct, YOU must manually change the settings, but it will still give you a meter reading from where you locked the exposure to.

My understanding is that I should be able to take a meter reading that will hit the exposure point I want and then lock that exposure, so that I can recompose the shot and take the picture I want. For example the shot I wanted to take had pretty much one colour wash of white, and when I set the ap. and shutterspeed it kept coming out overexposed, so I wanted to lock the exposure a couple of stops lower so that I could prevent that, but the AE lock won't come on when I press the button. I don't know if it's something I'm doing wrong or something with the camera.

Yea, the lock is for 'AV' , 'TV', 'P' and 'A-DOF' modes. In 'M' there is nothing to lock.

Maybe AV or TV are more suited to your needs, and use the exposure compenstion.

Maybe take the lens off auto focus?

press *

Put it in AV mode, focus on what you want, hit the * or AE-L button or whatever it is, recompose, then fire away.

Or, point your meter at the scene as you want to expose in AV mode. remember your settings, switch to manual, set your exposure and then fire away.

Right now that's my work around, but I'm not comfortable having a function not working properly on my camera, when I'd like to expand my creative uses, and understanding of my camera.

Have you tried the green rectangle mode? Maybe you'd be more comfortable using that.

I believe AV and TV modes let you choose one setting and the camera picks the other to get a proper exposure. In Manual, you're not allowing the camera to select shutter OR aperture, so there's no way for it to lock an exposure (the * button shouldn't work). I don't have the manual or camera with me to check, but that's what I would expect.

Scalvert said what I was trying to say a bit more eliquently! Its not a problem with your camera, its just not meant to work that way!

You're right, Scalvert. There's no exposure to lock because when you half-press only AutoFocus changes, not exposition.

Edit: not fast enough

Thanks for the heads up. I played around some more and got it. I appreciate the help from all of you. Thanks for taking the time guys, again I appreciate it.

The easiest way is to put the center of the frame at the lightest point or subject then overexpose few notches.
