just calibrated my 5dm3 with focal plus as I noticed that my shots are being far from sharp.
had EV of 6-7
100-400mm W+6 T+13
24-105mm W+5 T+15
That is quite hardcore isn't it? Btw does +1 stand for 1mm or cm?
First off, I'd add light and try again. Your results may be ok, but IIRC FoCal recommends at least EV 8, and they used to recommend EV 10.
Each unit if AFMA represents 1/8 of the depth of focus for that lens at max aperture, so the absolute value actually depends on the lens. So, if you need +8 or -8, you're off by a full depth of focus. Note that depth of focus is related to depth of field, but is measured at the sensor, so the units are actually down in the micrometer range of physical distance.
