i am new to pinhole photography and would like to ask you if you could give me guidelines and some information on exposure times for zeroimage camera - 612f,please?

i am using iso 100 (ilford FP4) and fuji 160NS

Pinhole Size: 0.25mm
Focal Length: 40mm
F/158 (pinhole), F/55 ( zone plate)

If you could tell me if there is difference in exposure time when using zone palate and normal pinhole ?

Thank you
