Parallax in Rifle Scopes (Telescopic Sights) Imagine this is a scope … Target Objective Lens – – – Reticle Focal point of the target image on the reticle. There is no parallax. Target image focal point past the reticle. There is parallax. Target image focal point ahead reticle. Again, there is parallax. The parallax effect can be avoided by positioning the eye exactly on the focal axis. If the position of the eye changes, but the focal point is at the reticle, parallax does not occur. Otherwise… Another way to cancel the parallax effect is to use adjustable objective lenses. Another illustration: Target Reticle Eye Parallax from the point of view of the shooter. Imagine that only the eye is moving. After adjusting for parallax, the position of the eye is not critical. Parallax in a real situation. The target is fixed, the scope is also motionless, only the camera moves. Now with parallax canceled through the lens setting. Enjoy it, share, subscribe and hit the notification bell!
