Hi Am
Thanks for your reply.
Q1-Answer: Yes, in #1 the Red Rectangle is how Canon's DPP V4 represents the Live View AF rectangle on the full size image. The frog image is a screen capture of part of the full size (100%) image.
Q2-Answer: Not in Live View - you only get the choice to spot focus & small spot focus in normal TTL mode when looking through the Viewfinder.
Q3-Answer: The small White Rectangle is the illustration in the Canon User Manual of where the AF Rectangle is. The Red Rectangle in #3 is where Canon's DPP V4 is telling me the Live View AF rectangle was on image of my computer screen which was displaying the pdf of the Canon User Manual.
Cheers
Dennis
