6X24CM - 85MM Focal L. - 0.390MM Dia. Pinhole - What its sharpest, closest subject distance ?

I am building an 6X24CM Panoramic pinhole camera. Curved plane radius is 85mm and pinhole diameter is around 0.39mm laser drilled. What is the closest but sharpest camera to subject distance for archaeology museum ?

If you want sharp, a pinhole is not a great choice.
