Good to know. Thanks for explaining this.

Damn I couldn't figure out why it wasn't working on my t2i. For any noobs out there like me this will now work in manual mode. I'll get to great pictures soon though. Thank you for posting this.

thanks for the comment! I've trying to figure this out for hours. I wasn't sure how to use AE lock for my camera. I was using manual mode and wasn't sure why I needed it. Found out...I won't be using that feature at all in manual mode. Thanks!

You do not need AE Lock in Manual Mode as you have already locked the exposure by taking control of Aperture and Shutter speed in Manual Mode.

Hy.I own a 450D and i tried the AE LOCK , but it seems to me that it works only in AV and TV modes and not in Manual mode.

Is that right?

I think it's a great video on explaining what the AE Lock is and how it works but I wouldn't consider it an advanced tip..? What I'm interested in is why you would want to take a light metering from somewhere other than where your subject is located..? When you use a hand held light meter you hold it right up against your subject, not a meter away...? Something I don't understand, if you could explain a practical use for it..? :]
