Does the "Depth of focus" vary with focal length? And how does that vary?
In practical terms, what does that mean to a photograph, rather than a theoretical absolutely flat target and perfectly flat film - all parallel to each other.
So say I have a scene with close foreground vegetation, lily pads and vertical water reeds mid distance, and high peaks in the back. Is a longer lens more tolerant of not getting my scheimflug perfectly set up? or is it an advantage to compose to shorter focal lengths?
Short of hitting the diffraction limit, and in practical terms of stopping wind blown flowers, what are the better strategies?
