The new EF 1.4x II extender replaces the previous highly regarded EF 1.4x extender. When combined with the EOS-1V & the EF supertelephoto lenses with image stabilization, near imperviousness to weather extremes is acheived thanks to the new rubber gasket seals. Improved antireflective internal coatings also increase transmissivity & performance in backlit conditions.

NOTE: This teleconverter will only fit and work with a select list of lenses. Please click here for a compatibility chart of all compatible lenses.

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).
