The measuring system they use for cameras includes the focussing system. IMHE the Chasseur d'Image camera reviews are the most comprehensive and accurate I have seen published. FWIW the guy liked the camera a lot in the first installment and still liked it, it just did not have an accurate enough rangefinder to focus the 50 and 35 lenses within their depth of field whilst wide open. I shall probably not buy one now despite wanting one very much!
