Thank You TOF Guy and very thans for your french translation.

In fact, I notice the problem is not present every time. I think it is due to the contrast of the subject. I have the problem only in macro (60 - 70 cm). Indeed, the collimator is small and does not cover a large area. I then practice by turning the focus ring to focus manually and then I press the shutter button to activate the AF ; and then there, all is perfect.

Best regards
