You need to update the firmware and can also make certain user settings on the lens, e.g. adjust how much the focusing wheel reacts, etc.

Do you need to know 🤷
If ne old firmware is on the lens, this can make a pretty difference as day and night. So I came to a cheap 100-400mm – the owner thought it was broken because the picture stick was crap. New firmware and the image was suddenly bomb-resistant stabilized.

Right.

But if you are satisfied with the current functions of the lens, you do not need it.

You can photograph without such additional settings.

It was already used for half.
