Re: TS-E focusing question


To learn how to use the tilt shift lens you need a simpler scene. One that is flatter, where you can easily define the focal plane. The problem is that downward tilt will not automatically buy you infinite dof, but when used properly will give you in-focus in a plane. The depth (or thickness) of the in-focus plane will depend upon your f stop. It will all become much easier if you choose a practice scene that is flat, without vertical components in the foreground. (your near field bushes complicate the definition of where the focal plane is). No over hanging branches, etc. as objects in the top of the frame will be oof unless they are at infinity, or unless you are tilting your focal plane L-R, etc. I first practiced in my driveway until I felt confident of my technique when very close to the ground.
Read this as an estimate of tilt angle:

Example of flat plane (horizontal usually) 24 TESII






If the seaweed and rocks varied more in height, I would have had to use a smaller aperture to gain the greater dof to cover them.
