On my GH2 I punched in the rear wheel for magnification of the image so I could focus manually. Can't find that on the GH4. How do you punch in when shooting with legacy lenses?
Thanks, guys- I didn't mention 'when I'm looking through the viewfinder' so it was the Fn3 button I was looking for! Strangely enough, no mention of it in the manual in the 'manual focusing' chapter..?!
