Canon 1 4 Extender

A Quick Guide to Canon 1.4 Extenders

Extenders can be very useful when it is not possible to get closer to a subject. When used with compatible lenses, theyre able to boost the focal length and lengthen your reach when capturing images. The Canon 1.4 extender is a series of teleconverters designed for use with Canons EF lenses.

Compatibility is a critical consideration to keep in mind when deciding which teleconverter to buy. Compatible mounts are required for all Canon 1.4x series extenders. Lenses must be designed to accommodate the protruding front on a Canon extender. Since these two components must communicate electronically, lenses must have the correct number of contacts. Electronic contacts are responsible for sending aperture data to the body. Buyers can check the Canon 1.4 Extender III compatibility chart to help them choose the right product.

Yes, you can. When a photographer needs an image to fill the lens, stacking extenders is a practical solution when the use of a single teleconverter simply won’t suffice. Wildlife photography is one example when a Canon Extender EF 1.4x III can help you capture more from a smaller lens.

Deciding which version to get will depend on your specific photography requirements. Here are some differences that set the models apart:

• Weight: Although both models are the same in length, the EF 1.4x III weighs 0.80 ounces more than the Extender 1.4 II. The difference in weight is due to the two extra two lenses which come included with the III. See the manufacturer site for details.
• Endurance: The Canon 1.4 Extender III is designed with more endurance than the II and includes an improved lens mount stopper. The III uses 7 screws to attach the lens mount to the body of the camera, while the II has only 4 (see the manufacturer site for details). This improvement allows the Extender III to accommodate bulky cameras more easily.
• Autofocus: Handling is another area that distinguishes the Canon 1.4 Extender II from the III. The Canon 1.4 EF III has an AF speed thats about 10% faster than the II. See the manufacturer site for details.
