DOFIS just gets better and better

As previously mentioned, I consider DOFIS the best script that I've written. It does what it was designed to do and as best as it can.

In this post I'm going to be talking about the latest DOFIS enhancements that should, IMHO,  result in Magic Lantern photographers or videographers having DOFIS running all the time.

DOFIS now does the following:

• Shows the depths of field (DoFs) if the focus is less than the hyperfocal;
• The DoF display can be switched between showing the defocus DoFs relative to the focus or in absolute mode. DOFIS alerts you by displaying R or A. If one of these options is on, then DOFIS will still show infinity blurs once you are focused beyond the hyperfocal, thus allowing you to choose your infinity focus based on blur in microns;
• DoF display can be switched off, so DOFIS always shows infinity blurs in microns, ie the infinity defocus blur, the diffraction blur and the infinity total blur;
• DOFIS now allows you to switch off the bracketing feedback, ie better for videographers;
• In the lens model Auto mode, DOFIS will look for a registered lens and use it if found. If not found DOFIS will default to the standard thin lens model. DOFIS alerts you to what model it is using, ie S for split and T for thin;
  
• DOFIS always alerts you to the number of brackets you will need to take from the current focus to the hyperfocal;
• Finally, in the DOFIS menu, under Additional Info, which is dynamic and responds as you change focus and aperture etc, you can toggle through the following:
• Pos = focus position
• LN = Lens Name
• LT = Lens Thickness
• LE = Lens Extension, ie focus extension from infinity focus
• FP = Front Principal position relative to the sensor plane
• M@x = the magnification at focus position x
• (Added) Defocus = defocus blur at the near & far DoFs, ie diffraction aware

As an example, here's what the DOFIS menu looks like:

Here we see the DOFIS display is ON; the DoF display option is set to show the relative near and far DoF; that bracketing feedback is off; that the lens model is in Auto mode and it has found a lens; and that the lens thickness is 86mm, which means the DoF info now matches the manufacturer's data at the maximum magnification. To see the difference, select M@x and toggle between the split and thin lens models. 

Finally, here is a screen capture showing what the DOFIS display looks like, using the above settings:

Here was see that a split lens model is in use (S), that 4 brackets are required to focus bracket from the current focus (36cm) to the hyperfocal; that DOFIS is displaying defocus DoFs, ie ignoring diffraction, in a relative mode, ie the near and far DoF either side of the point of focus; remembering that the blur at these DoFs is the blur you set in the ML CoC menu.

As usual I welcome feedback on DOFIS, especially from users in the field.
