Am I mistaking or does this camera have a peaking feature? I was wondering if anyone has used this feature yet and how well it works...

Yes, and it's the same peaking feature as found on the XL H1, if you want to search there for feedback.

I really like the peaking feature it works great. When combined with the magnification button you can get perfect focuses every time.

I read in another thread that zebras and peaking cannot display at the same time... is this true for the A1? Both the EVF and LCD?

Correct. You can have one or the other. When peaking is enabled, the zebra falls away.
