You can choose your color and the level of the peaking effect. To try it out while waiting for Leica pick up a Sony Nex 5 or Nex 7. As others have mentioned you see the effect on the whole screen, it accounts for your depth of field so the effect shows you what will be in focus as you stop down fairly effectively. Caveats would be it is a learned tool much like focusing on ground glass; if you turn up the peaking level you can get false positives as the peaking color bleeds over into areas that are not really in focus. Also, if your lens doesn't have a crisp transition from out of focus to in focus it can be difficult to use; a wide angle like the 18mm Zeiss will show everything in focus or a 35 Summicron stopped down to F8 at intermediate distances will show most everything glowing in red(or yellow or white). The plus side is that it will put new life in lenses such as the 75 Summilux as focus peaking takes into account field curvature so you really can focus off center quickly and easily. Also, with the right adapter you can now use any lens in your stable or do macro with your M. If any of you do decide to go and check out the principle with a Sony Nex you will need to use its somewhat ill conceived menu. In the menu go to the lower right option and scroll down, way down until you can set several things. 1) allow firing without a lens attached 2) allow focus peaking 3) choose a color 4) choose a level of focus peaking. Also enable manual focusing. Thanks for listening and now back to lurking.
