Kenko Tokina PRO 300 DGX 1.4x Canon Lens Multiplier

Boost your lens capabilities with the Kenko PRO 300 DGX. Key features: Multiplies focal length by 1.4x, high-quality optical construction, preserves signal integrity between camera and lens, minimal loss of performance and image quality, maximum reduction of internal reflections for optimal image quality, functional autofocus (see note). Note: Using a focal multiplier reduces the effective aperture of your lens by 1-2 stops. It's recommended to use a telephoto lens of at least 100mm f/2.8 or brighter for best autofocus performance. Most Canon EOS cameras will disable autofocus if the combined effective aperture of the lens and converter is below f/5.6.
