Hi,

Is it possible to know/calculate what will be in focus given the f stops

Like if I set f 3.5, what distance/depth will be in focus?
If its a zoom lens, how does it affect?

Thanks

Then the calculated depth of field is only valid for one particular focal length. The moment you change the focal length (vulgo: zoom in / zoom out) the value for DOF changes.
