The EF 600mm f/4 IS USM Canon lens weighs 11.8 lbs and measures 6.6" in diameter. Meanwhile, the length of the lens is 18". The magnesium alloy body helps keep the weigh down without sacrificing its strength. The lens also comes with a fiber lens hood.
The build quality of the Canon EF 600m f/4 IS USM Lens is excellent. The switches and focus ring all work smoothly. The lens just screams high quality throughout.
The included Image Stabilization works great. As for the Ring Ultrasonic Motor (USM), it can achieve a very quick, accurate and silent autofocus. Full Time Manual focusing, as expected, is also available. Meanwhile, the combination of the 8-blade aperture and telescopic compression can produce a great background blur quality.
Image quality is excellent, as there's very little vignetting and Chromatic Aberration. Sharpness and contrast is also exceptional. The lens is most suitable for outdoor photography, specifically animal photography. It is also suitable for other long distance photography.
