The farther away the lens is, the closer the focus, the greater the magnification.This extension tube set does not affect image quality as there is no optics inside. In comparison, close-up filters are often blamed for degrading image quality.Features:Lightweight designMaterial: Alumium + PlasticPerfect coupling with TTL.AE MeteringUse Individually or CombinedSpecifications:Lengths FOR tubes (mm):Tube #1: 13Tube #2: 21Tube #3: 31IMPORTANT NOTE: This extension tube set is SUITABLE FOR CANON EOS DSLR/Film SLR/LENS ONLYPackage Contents1x NEEWER 3-piece Macro Extension Tube Set1x Protection Bag1x Manual"
