Canon EF 2x II Extender w/LP811 Lenses Pouch (Used)

The new EF 2x II extender replaces the previous (and highly regarded) EF 2x extender. New on the EF 2x II is added weather-resistance to the front and rear mount surfaces to match the level provided by the EOS-1v and the new IS super-telephoto lenses. Optically redesigned for better performance the EF 2x II extender also features new internal anti-reflection construction that improves contrast even when shooting in heavy backlit conditions

NOTE: When used with the EOS 5/A2/A2e camera, exposure compensation must be set to - 0.5 EV with the 1.4x II or - 1.0 EV with the 2.0x II. Autofocus will work only if the effective aperture is within the range of the camera (currently f/5.6 with most EOS cameras but f/8.0 with EOS 3 & 1V).
