Description:

The effective aperture of the lens is increased by one stop. Autofocusing does not operate if the effective maximum aperture is greater than f/5.6 (greater than f/8 on the EOS 1V and EOS 3).

Features

Dust and moisture resistant construction
Extends the master lens focal length by 1.4x
Minimum loss of lens performance
Reduces inner reflection for higher image quality

The new version II maintains the outstanding optics of the previous version, and adds enhanced weather- resistant construction, and improved anti-reflective surfaces in the barrel

Successor to the EF1.4x this model offers valuable improvements for further enhanced image quality. This extender allows users to combine practicality and functionality with a new optical system allowing them to extend the master lens focal length by 1.4x, with minimal loss of lens performance or image quality. With a dust- and moisture-resistant construction this extender has been designed to reinforce the EOS system. Specially designed to work in conjunction with the EOS-1V and IS super telephoto L-series lenses, it makes a highly dust- and water-resistant combination.

The EF1.4x II features improved anti-reflection materials inside the lens-barrel as well as improved coating around the outer edges of the lenses to reduce flare. All of these improvements will allow professional photographers to capture higher quality images than ever before.

Pros:	Optics, size. weight
Cons:	AF does not work with all cameras or lenses

I only use it with my EF100~400L IS USM lens. Outstanding results. I cannot fault it when used with the 20D and 10D and the lens.

Happiness is.
