Vivitar 58mm 2.2X Professional Telephoto Lens

hi there izzy from digitalgoja.com showroom and they've posted a couple of questions on our forums about how to work with the 2.2 x super telephoto lens adapters this one happens to be the altura version number one we always have to make sure that since these adapt to the front of our lens you have to purchase the correct filter thread size because they actually thread on just like a filter so for example this one happens to be an 18 to 135 EFS lens so this is a 67 millimeter diameter thread so then here we have the two-point 2x teleconverter with a 67 millimeter diameter thread so number one we have to prepare for this first set your lens to manual focus you want to make sure that this is zoomed out to give you a little bit of room and that it is on manual focus so that we don't run the gamut of stripping the gears for the autofocus system so we're now going to remove the rear cap and
