Product Info

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: 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).

NOTE: This Teleconverter Will Only Fit And Work With A Select List Of Lenses. Please Check The Compatibility below.
