    Hi, I am an inexperienced owner of a Hasselblad Arcbody with the 35mm and 45mm Rodenstock lens. It has a split image focussing screen.
    I've only been using the camera for landscapes so generally focussed on infinity.
    Recently on a wet afternoon I started playing with it indoors and found that if I focussed using the split image the lens might say 2.3m whereas the measured distance was 1.5m. At first I thought a lens fault but found the same thing happening with both lens. Is this a common aberration with this type of focussing system and which is most likely to be correct, the split image distance selection as seen in the prism finder or the actual distance measurement from the object to the film plane? Thanks.
