I bought a brand new canon lens it turned out to be a grey import as the seller could not provide a vat invoice. I am trying to return it if it can be done delivered to uk address but apparently came from Australia probably from hong kong. the focus is very slow I have done a test video please see the below link and watch it. After watching a review of the lens from another person it seems to me the focus on his lens is quick and my lens is very slow. https://youtu.be/7iOiEbCVNaM
Please let me know what you think any advise would be helpful.
hello I was using ai servo centre focus point back focusing
I've never been a fan of back button focus. Instead I use AIServo and just reprogram the AF ON button, to AF OFF. Since most of the time I want continuous focus, and only occasionally want to suspend it. That way most of the time I only have to worry about pressing the one button, and the few times I want to suspend focus have to press two. Instead of the other way around.
