What is the dial on the left side of a scope?

Side Focus - Some Leupold riflescopes have a side focus dial on the left side of the turret. This is used primarily by long range shooters to bring distant targets into the same focal plane as their reticle in order to eliminate parallax and provide the best possible focus on the target.

What does the side focus do on a scope?

The main purpose of the SF (Side Focus) feature is to provide optimum accuracy over a wider range of distances by correcting for parallax error.

What is controlled by the side dial on a telescopic sight?

Telescopic sight adjustment
