Canon Extender EF 2X III. B&H # 2839034 MFR # 4410B002. 588 Reviews. Key Features. EF Mount Teleconverter. 2.0x Magnification Factor. Microcomputer Controlled. Communication Between Lens & Camera. I was pleasantly surprised. At 19m distance from the charts, the RF 2x performs far better on the 100-500mm than does the EF 2xTC on the 100-400mm II. The 100-500mm at 1000mm produced crisp lines, and gave 40% more resolution than the bare lens and about 20% more than the 100-500mm at 700mm.

The Canon 100-400mm Mk II is also compatible with the Canon 1.4x extender, though it will only autofocus on higher-end Canon DSLRs that retain AF up to F8 (currently 7D Mk II, 5D Mk III, 5DS/R, 1DX/II). The 2x extender will physically fit, but all AF functions are disabled. The Canon 1.4x III Extender extends the reach of the Canon 100-400mm f/4.5-5.6 Mark II lens to 140-560mm. This is my review of the Canon 1.4x III Extender on 1.4x III + 2x II + 2x III. I understand that the quality with stacking will deteriorate, but the 70-200mm f/2.8 II would still keep autofocus on the 1D IV with the first three combinations with 728mm FOV, and the last extreme combination would result in a crazy 1456mm on the 1D IV or 1792mm FOV on the 7D with MF.

The Canon EF 2x III Extender mounts between your Canon EOS Digital SLR and a compatible lens (primarily Canon L Series lenses), extending the focal length of the lens by a very noticeable 2x.
I repeated this test with the EF 400mm f/4 DO IS II. Extenders 1.4X III and 2X III were subsequently added on. This test was repeated three times for each case and the values averaged. the video clips below compare the EF 300mm f/2.8 IS II + Extender 2X III with the EF 400mm f/4 DO IS II + Extender 2X III.
