Hi Wim, may I also ask a theoritical/technical question here. In an ideal case, the optical axis of the lens should be orthogonal to the image censor and pass through the center of the sensor. But in reality errors always exist: if the optical axis of a lens is not perfectly orthogonal to the censor, then there is a tilt; if the optical axis does not pass through the center of the censor, then there is a shift. How large this kind of errors are considered to be within the acceptible limit?



Regards,

Frank
