|The VAF-TXi is very simple to remove from your camera. As before, please note:
Cleaning If you accidentally touch the filter's coated optical surfaces, fingerprints can be easily wiped away using a just a single drop of alcohol on a piece of soft cotton cloth. Most alcohol-based lens cleaners can be used as well. As with any optics, avoid vigorous scrubbing, and be careful not to drag abrasive particles across the surface.
Camera OFF while Mounting / Dismounting Lens If certain older EF lenses are removed from a Rebel HDSLR while it is turned on, their iris setting may be misread by the camera when they are reinstalled. (This issue is unrelated to the VAF-TXi, and can happen even if the VAF-TXi isn't being used.) The power on/off instructions included below will ensure that this doesn't happen. If you inadvertently remove a lens with the camera on and cause this to occur, the solution is just to manually adjust the camera iris control to fully open the lens, and then to re-adjust it to your desired f-stop.
Please note that the photos below illustrate the Canon 7D and the VAF-7D; however the removal process for the VAF-TXi is the same.
