You need MFA because of manufacturing tolerance on both the lens and the body. Your MFA of +8 could just as well be from you 7D2 as the lens. I MFA my lens on both my 7D2 and 70D they are not the same, 7-8 difference for most of them. Even if you have the lens calibrated it does not mean it will be right on another camera.
