Summary:A lens front cap module and an image pickup apparatus having a zooming barrel, a focusing barrel and a lens front cap body. Both zooming barrel and focusing barrel are hollow barrel shaped structures. The focusing barrel is installed in the zooming barrel. An abutting portion is formed on an inner wall of the zooming barrel. The lens front cap body comprises a driving plate and a vane module. The driving plate is installed at an end of the zooming barrel and has a central window aperture. A driving pin is axially extended from the driving plate. The vane module is disposed on a side of the zooming barrel for shielding or unshielding the central window aperture. When the abutting portion abuts the driving pin, the driving pin drives the driving plate to rotate, and to drive the vane module to shield the central window aperture.
