this set of instructions is the equivalent of handing the keys to a high performance car to
a child and telling them to go to a parking lot and drive around for ten minutes and
then expecting them to be ready to handle a california freeway.
It offers no instruction, guide lines, standards, warnings or anything of value.
...and the video does not cover autofocus "accuracy" (can i microadjust?) nor "repeatability" (should i return it?). My sigma50mm1.4 was terrible in terms of AF repeatability. The 2nd copy is better but I still manual focus as well as AF just to be sure. The video shows a "flat to the sensor plane" test target which will be of no use for microadjust. If you dont deal with that....ALL your photos will be soft, forever, on AF...and you will think it is just the best you can get....not sure what else you may be referring to but would be interested for you to expand your thoughts beyond the metaphors...
