Focus Bar Update

Just a quick post to say I've updated my focus bar script (FOCUS on the right).

This version provides additional near depth of field distance information when you are optimising infinity focus.

If the full info option is selected (default) then you see both near and far depth of field infinity focus sets of data, ie:
  • In the far field, ie at infinity, you get a breakdown of the defocus, diffraction and total blurs in microns;
  • In the near field you get the depth of field distances that correspond to three 'blur scenarios', eg: infinity defocus blur, twice the infinity defocus blur and the ML CoC set defocus blur.
The script as provided is good for a visible band, full frame 5D3. For a cropped Infra Red camera, for example, you will need to tweak the script.
