I wonder if anyone has experienced this?
I have just purchased a Combo Wide RS camera with a Schneider App-Digitar 47mm XL lens using it with a Phaseone IQ150 50mp back.
The problem I am having is with the depth of field scale on the helicoid mount. Normally I would set the infinity to the f stop on the right of the scale to get the maximum DOF, however when I set this to the mark, say f11, I cannot achieve infinity focus. In fact the only way to get infinity focus is to set the infinity mark to focus point? Reducing the hyperfocal distance.
Is this this the case with digital backs on this camera? if so, why are the DOF f stops marked out f5.6- f32 in both directions on the helicoid focus mount?
I phoned my dealer in the UK who told me digital backs tend to work best between f8- f11 but was not sure about the DOF issue, hopefully someone can help me before my next shoot?
