Make sure you read through both pages before attempting anything. It's possible that it may need some adjustment but that isn't the end of the world if it's within your camera's tolerances, just don't get too caught up on it (that bit is so important i've put it twice) make sure it works then enjoy it. I've wasted too much of my own time pratting about and getting myself stressed out over cameras that were fine to start withWhich camera and lens do you have?![]()
It developed problems further down the line but let's not go into that. Run the tests and see what you get before worrying about it, chances are it's fine I'm assuming you've had it on the camera by now even for just messing about, has it behaved the way it should so far?
