AEL button on 70D

When you are taking a panorama can you press the ael button just once to lock exposure or do you have to hold it down continuously while taking your shots on a Canon 70D? Thanks in advance.

Apparently depends on what you method you select -
"Note that there are multiple Auto Exposure Lock (AE Lock) options, such as when setting the function of the AE Lock [*] Button (see Figure 3). The AE Lock option will lock the exposure for the current scene when you press and release it. If you reframe the shot and want the camera to re-evaluate and re-lock the exposure, just press the [*] Button again. The AE Lock (while button pressed) option only applies to the Shutter Button, and will lock the exposure as long as the Shutter Button remains half-pressed, similar to how the camera works with the One-Shot / Evaluative Metering default settings, as described above. This differs from assigning the Shutter Button to Metering start because with Metering start, the camera will start evaluating for exposure, but the exposure values will not be locked but will continue to change until you take the photo or press the AE Lock [*] button (when you are working in Partial, Spot, or Center-Weighted Metering Modes). Again, you can see this in action by half-pressing the Shutter Button to start metering, look in the viewfinder (or on the LCD Panel) at the exposure settings, move the camera around, and see the settings change. The AE Lock (hold) option (indicated with *H) will lock the exposure and maintain that lock with those exposure settings for all subsequent shots, until you press the AE Lock [*] Button again. The AE Lock option without the (hold) option (indicated in the menu options with *) will only lock the exposure settings until the metering timer ends (the exposure numbers disappear in the viewfinder and on the top LCD Panel)."
I think it would be easier to get your exposure and then switch to MANUAL mode and set it. Once you take your pano shots you can switch back to an AUTO mode.

To take a Panoramic I 1. Set the focus on manual. 2. set your f stop and shutter on manual. 3. with you camera level overlap the pictures by 25% or more. PS some times you might want to shoot in the portrait position.
