43 Rumors has found a great video on how to fake focus peaking. See below -
Keep in mind that if you shoot RAW + Jpeg you’re going to run into a problem and that is the OMD will put priority on the exposure of the Jpeg therefore shifting the exposure of RAW capture. However read a comment from 43 Rumors reader Lucio -
“you can save your setting with the art filter on as mysetting num 1 for example.. and the assign to the fn1 button that setting..
In this way you can hold click and you have the art filter on…. focousing, release the button and the press the shutter… so in this way you have the horrible effect onlyu when you want to focus holding the button… so basically focus peaking on demand”
Great suggestion Lucio and excellent example of using the Fn1 button.
