| This extender has been re-designed optically and offers excellent
performance with compatible EF lenses (same as the Extender EF
1.4x II). Features a new seven-element design, and same weather-resistant
design and anti-reflection internal construction as the new EF
1.4x II. The EF 2x II doubles the focal length of any lens it's
mounted to, and reduces its effective aperture by two stops. With
the EF 2x II, AF is possible with any EOS body if the lens has
an f2.8 or faster maximum aperture, and compatible Image Stabilization
lenses maintain the IS feature when used with any current EOS camera. |
