Manufacturer description: The Pro 300 family are designed specifically to be used with prime telephoto lenses of 100mm or above, such as 300 mm f/2.8 lenses, and work best with telephoto lenses of 200mm to 500mm. With the 1.4x, DGX full AF operation is possible with camera lenses having a maximum aperture of F4 or brighter. Kenko does not recommend them for zoom lenses that have a range starting under 50 mm.
