Canon G16/G15 Quick-Change Adapter Kit 52mm by Lensmate
Now you can add filters to your G16/G15 without a bulky tube adapter.Only the tiny receiver stays on the camera (it adds only 3mm to the depth of the camera). The filter/filter holder assembly bayonets onto the receiver for quick changes without having to thread the filter on and off. The filter holder is retained by a low tension locking system, so very little torque is applied to the lens barrel when attaching and detaching it.There is no chance of flash blockage at any focal length (with the filter holder removed), since the receiver is the same diameter as the end of the lens barrel. The receiver adds only 3mm (about 1/8") to the total depth of the G16/G15 camera. It attaches to the camera using a 3M dual-sided adhesive film which holds tenaciously yet is easy to remove cleanly and safely when desired.We designed the system so that the filter remains in the filter holder and is attached/detached as an assembly. The filter holder bayonets onto camera with less than 90 of rotation to the locked position.The low tension locking system assures that the lens barrel won't be harmed by over-enthusiastic tightening (or loosening) of the filter. The ability to quick-change the filter in changing light conditions without having to thread/unthread should appeal to filter users.You may add the Hakuba collapsible rubber sun hood 52mm or the metal slotted hood 52mm with no vignetting at any focal length.
