Dot-Tune: Autofocus Fine Tuning in under 5 minutes
A little bit more testing using a sheet with half white, half black with a solid. With the vertical line, the tune value is +7. With a horizontal line, the tune value is a -1.5.
What gives? Obviously, the AF sensor is reacting differently to horizontal and vertical information. My question is, is this normal? Anyone else with a 5D3 experiencing this? My camera is new... wondering if I should exchange it.
EDIT: The focus difference appears to be the largest with my 24mm TS-E. With the 14L, 35L and 100L, the difference is about 2-3 points instead of 5-6.
