Fixes the weakest point of the G1 X

Due to the large optics was an automatic shutter, as you are used to it from the smaller PowerShot G models, can not be realized. Instead, Canon delivers with a manually-to-install lens cap. This is just annoying, especially if you used a camera bag as the Canon SC-DC75.
Although offered here automatic closure seals not hermetic, but it provides for the automatic sent obscuring the optics when the camera is turned off and protects the lens so from coarse dirt and fingerprints. In addition, the camera fits with this automatic closure in the camera bag.

Perfect solution. Although only plastic, so the part does make a sufficiently robust. Purchase is really worthwhile for me a very important accessory for the G1-X.
