Canon EF 1.4X II

Overview

• 1.4x magnification of the focal length of the lens used

• Excellent image quality

• Highly resistant to dust and water

• Improved communication between lens and camera

• Optimized lens coatings

• Compatible with L-Series telephoto and telephoto zoom lenses

• The Extender EF 1.4x III is compatible with most of CANON's main professional L-series telephoto and telephoto zoom lenses, which extends the focal length but only reduces the effective aperture of the lens by one point.

Focal length extension for super-telephoto lenses

The Extender EF 1.4x III is specially designed to work in conjunction with the L-series IS super-telephoto lenses, extending its focal length by 1.4x. The design of the teleconverter ensures that there is no loss of lens performance or image quality.

High quality construction

Improved anti-reflective materials inside the lens drum and coating of the outer edges of the lenses reduces flare. The construction is dust and water resistant, which helps maintain image quality.

Improved communication between lens and camera

A built-in microprocessor provides precise data transfer between lens and camera, and provides improved performance in AF and metering functions.
