  • Please note: teleconverters will cause some lenses to stop autofocusing. This is because they lose light – 1 stop for a 1.4x, and 2 stops for a 2x. Camera manufacturers design their autofocus sensors to work with lenses of f8 or faster, and so when a 2x converter is attached to a 70-300mm zoom with an aperture range of f4-5.6, this becomes an f8-11, and at the 300mm end, autofocusing stops. It’s only really a problem if you intend photographing moving subjects.
