Hi Rick...

I very much appreciate the analysis...and phenomenal pics.

I just want to make sure I understand your methodology. You started at 15 ft, and moved back in 3 ft increments. So is:
  • x1.0 = 15 ft
  • x1.1 = 18 ft
  • x1.2 = 21 ft
  • x1.3 = 24 ft?


If this is the case, and the 7D II was barely better than the 5DII at x1.2 vs x1.0, then that would be 21'/15' = 1.4x (+)

So, if that is correct, the 7D II's advantage is roughly equivalent to an optically perfect 1.4x TC without the 1 stop loss of light (but DoF differences)

If that interpretation is correct, not bad at all.
