Well, actually no, it gets set back a good 7 mm or so. Therefore, you just need to put a mark on the rails where the front standard needs to be set back when using the Frankenroid back :-) Or get an extra set of stoppers. Cool thing is, the rangefinder works perfectly since you're not changing the lens. Just need to find that exact right spot where the front standard should be.
