I reckon the back-focusing in my sample is not related to RSAs if you mean that. But sorry, I've to return the lens today so I can't look into this any further. RE: Next OL lens test report: Canon EF 70-200mm f/4 USM L IS II - Brightcolours - 08-06-2018 Did it back focus only in One-Shot mode (focus priority) or also in AI-Servo mode? Or did you not try that? The lens does not only measure nicely (sharpness), but also is very nicely engineered: https://www.lensrentals.com/blog/2018/08/nearly-complete-teardown-of-the-canon-70-200mm-f4l-is-ii/ |
