question on half-press exposure lock (100D / SL1)

Hello,

I am a new owner of a Canon 100D - I bought it primarily to record videos for teaching. I have installed Magic Latern on it (the latest iso-experiments version) and I am very positively surprised about this camera so far.

However, I noticed something a bit odd (compared to other cameras): if I half-press the shutter button in live-view mode (stills not videos) then the exposure is *not* locked, whereas using the OVF the exposure is indeed locked on half-press.

Is there a way to adjust the settings so that exposure is locked when half-pressing the shutter in live-view mode?

Many thanks!

found the solution (or explanation) on page 122 of the handbook:

"With (Evaluative metering), the exposure setting will be locked when you press the shutter button halfway and focus is achieved. In the (Partial metering), (Spot metering), and (Center-weighted average metering) modes, the exposure is set when the photo is taken. (Pressing the shutter button halfway does not lock the exposure.)

During Live View shooting, the exposure is set at the moment the picture is taken, regardless of the metering mode."

so the manual confirms that with evaluative metering live-view and OVF do behave differently.

To make OVF and live-view behave the same one needs to choose another metering mode.
