In addition, these converters have been specially tuned to accommodate the more precise specifications required in order to insure communications compatibility between the digital camera and lens. 2X Digital Pro Converter - EOS For use with lenses with a maximum aperature of f/4.5 or higher Lens Construction: 7 Elements in 4 Groups Lens Coating: Multicoated...

2x AutoFocus Tele Converter for most CANON EOS EF lenses. Simply attach this Converter between your camera lens mount and your existing CANON EF lens to DOUBLE your Focal Length. For example, turn your 28-90mm AutoFocus EF lens into a 56-180mm Zoom Telephoto. * PLEASE NOTE: This Converter works very well with Canon EOS EF lenses; however, it will NOT accept EF-S lenses.

Also, to ensure proper autofocusing, your camera lens Maximum Aperture should be f/3.5 or wider; even so, very dark subjects may cause Autofocus systems to fail (although you can always use Manual Focus).
