Great condition, no problems. Comes with 1.4x Extender.
The Canon EF 400mm f/5.6L USM is a high-performance telephoto prime lens, designed for Canon's full-frame and APS-C DSLRs. Known for its exceptional optical quality, robust build, and portability, this lens is a favorite among wildlife and sports photographers.
Optical Design and Quality
The lens features a relatively simple optical construction, comprising seven elements in six groups. It includes one Super Ultra-low Dispersion (UD) element and one UD element, which help to minimize chromatic aberrations and produce sharp, high-contrast images from corner to corner. The lens also benefits from Canon's Super Spectra coating, which reduces flare and ghosting, ensuring excellent color balance and contrast.
Build and Handling
Constructed with a durable metal body, the EF 400mm f/5.6L USM is built to withstand the rigors of professional use. Despite its solid construction, the lens is relatively lightweight at approximately 2.76 pounds (1,250 grams), making it easier to handle during extended shooting sessions. The lens measures about 10.1 inches (257 mm) in length, which is compact for a lens of this focal length.
Autofocus System
The lens is equipped with a ring-type Ultrasonic Motor (USM) for fast, precise, and near-silent autofocus performance. The USM allows for full-time manual focus override, enabling photographers to make fine adjustments without switching out of autofocus mode. The minimum focusing distance is 3.5 meters (11.5 feet), providing a maximum magnification of 0.12x, which is suitable for capturing distant subjects with great detail.
Aperture and Depth of Field
The EF 400mm f/5.6L USM has a maximum aperture of f/5.6, which, while not the brightest, is sufficient for most outdoor lighting conditions. The aperture can be stopped down to f/32, allowing for greater depth of field control. The lens features an 8-blade diaphragm, which helps to produce pleasing bokeh, or out-of-focus background blur, making it ideal for isolating subjects against a soft, defocused background.
Additional Features
- Built-in Hood: The lens includes a built-in, retractable hood, which helps to reduce lens flare and protect the front element from impacts and the elements.
- Tripod Collar: A detachable, rotatable tripod collar is included, providing stability when mounted on a tripod or monopod. This feature is particularly useful for long-duration shoots and when using slower shutter speeds.
- Weather Sealing: While not fully weather-sealed, the lens is designed to withstand some exposure to dust and moisture, making it suitable for use in various outdoor conditions.
Applications
The Canon EF 400mm f/5.6L USM is particularly well-suited for wildlife and sports photography, where its long focal length allows photographers to capture distant subjects with clarity and precision. Its lightweight design and fast autofocus make it a practical choice for handheld shooting, especially for capturing birds in flight or fast-moving athletes.
Conclusion
The Canon EF 400mm f/5.6L USM is a professional-grade telephoto lens that combines excellent optical performance with a durable and portable design. Its sharpness, contrast, and reliable autofocus make it a valuable tool for photographers who need to capture distant subjects with precision and detail. Despite its lack of image stabilization, the lens remains a popular choice for those who prioritize image quality and handling ease in a telephoto prime lens.
