When combined with pro level EOS cameras \u0026amp; EF supertelephoto lenses with image stabilisation, near imperviousness to weather extremes is achieved thanks to rubber gasket seals. Improved anti-reflective internal coatings also increase transmissivity \u0026amp; performance in backlit conditions.\u003c\/p\u003e\n\u003cp\u003eThe extender will cut back the amount of light by one f\/stop. For example using a 1.4x teleconverter with a 300mm f\/2.8 lens will effectively increase the focal length to approximately 420mm and the f\/2.8 aperture will now be f\/4. Teleconverters are best used with longer telephoto lenses and are not recommended for lenses wider than 50mm, e.g. 28-105mm (35mm format).\u003c\/p\u003e\n\u003cp\u003eAutofocus is possible on any EOS camera when combined with a lens having an f\/4 or faster maximum aperture.\u003c\/p\u003e\n\u003cp\u003eIf the lens is attached to an EOS camera having multiple focusing points and an extender attached, only the center focusing point will be usable for AF.\u003c\/p\u003e\n\u003cp\u003eWhen attached to the EF 180mm f\/3.5L Macro USM lens, the autofocusing range is from 80 cm to infinity.
