Canon Extender 1.4x Mk III

The Canon Extender 1.4 III increases the focal length of a lens by a factor of 1.4x while still delivering superb image quality (designed for select Canon EF mount L-series telephoto lenses).

The Extender EF 1.4X III from Canon is designed for select Canon EF mount L-series telephoto lenses. It increases the focal length of a lens by a factor of 1.4x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, it combines redesigned optics, improved data communication between lens and camera and enhanced environmental protection. It is ideal for photojournalists and wildlife, nature and sports photographers who need to get close to distant and challenging subjects and it reduces the need to carry heavy telephoto lenses.

Super Spectra and Fluorine coatings

The Extender EF 1.4X III features seven optical elements in three groups and all optical elements have Canon's Super Spectra coating to reduce ghosting and flare. A new Fluorine Coating on the front and rear elements makes marks, such as spots left by water or fingerprints, much easier to clean than standard coatings.

Capture balance, well-exposed images

To facilitate the accurate transfer of imaging data between the lens and camera body, the extender features an integrated processor which ensures all focusing, metering and ID information is available - allowing the photographer to capture balanced, well-exposed images. When combined with the latest range of premium Canon L-series lenses, these extenders enable AF accuracy even when capturing moving subjects. When attached, the 1.4x extender reduces the effective maximum aperture by one stop.

A carefully positioned lens release mechanism also makes it easy to mount the extenders quickly, reducing the time that the camera and lens are exposed to the environment. The extenders offer the exceptional build-quality expected from Canon's professional products, and are resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.

Note: This converter is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L. Additionally, please see your lens and/or camera body manual for full autofocus compatibility information with the Extender EF 1.4X III.

I recently swapped out my version 2 converter for the version 3 unit. I use it in combination with two lenses, the 500 f4 MK1 and the 100 - 400 MK2 mostly on my 7D2. The most noticeable improvement in image quality has been with the 100-400 lens not that the previous generation performed poorly.

AF speed does suffer, particularly on the 100-400 and obviously the 100-400 goes to f8 at 400. Note, some older generation Canon cameras will not autofocus at f8, e.g. the 60D.

Awesome piece of equipment

I used my 1.4 mk3 converter with my 7D mk1 camera and 300 f4 IS lens and also on my 7D mk2 camera and 400 f4 DO lens. I almost never take it off. I have not seen much (if any) image quality drop when using this converter.
