VILTROX DG-C AF Macro Extension Tube Set for Canon EOS EF & EF-S Mount

1.The AF Extension Tube Set can transform your lens into a Macro Lens. It moves the lens from the film or digital sensor. The closer the focus is, the greater the magnification. The extension tube does not affect image quality as there is no optics inside. In comparison, a close up filter is often blamed for degrading the quality of image. Auto-focus function can operate. 2.This is used by attaching between camera body and lens of the 35mm single-lens reflex camera.It comes as a set of tube of different lengths which singly or in combination makes it usable in 7 different lengths. 3.It couples perfectly with the camera’s automatic diaphragm.
