Canon Ultrasonic EF16-35mm f 2.8L II USM Specification

The Canon Ultrasonic EF16-35mm f/2.8L II USM Lens is a high-performance wide-angle zoom lens, specifically designed for professional photographers and advanced amateurs. It features a focal length range of 16-35mm, making it versatile for capturing landscapes, architecture, and interior photography. With a constant maximum aperture of f/2.8, the lens ensures exceptional performance in low-light conditions and provides a shallow depth of field for striking subject isolation.

This lens is part of Canon's esteemed L-series, signifying superior build quality and optical performance. It incorporates three aspherical lens elements and two Ultra-Low Dispersion (UD) elements to minimize chromatic aberrations and distortions, delivering sharp, high-contrast images across the entire zoom range. The Super Spectra coatings further enhance image quality by reducing lens flare and ghosting.

The Ultrasonic Motor (USM) provides fast, precise, and quiet autofocus, while full-time manual focus override is available for fine-tuning without switching modes. Its robust weather-sealed construction, with dust and moisture resistance, makes it suitable for challenging shooting environments. The minimum focusing distance of 0.28 meters allows for creative compositions even in tight spaces. With a circular aperture diaphragm, the lens produces pleasing background blur, enhancing the aesthetic quality of bokeh.

The lens is compatible with Canon's full-frame and APS-C DSLR cameras, providing an effective focal length of 25.6-56mm on crop-sensor cameras. Its compact and lightweight design offers portability without compromising performance, making it an essential piece of equipment for professionals seeking reliability and excellence in wide-angle photography.

Canon Ultrasonic EF16-35mm f 2.8L II USM F.A.Q.

What are the ideal shooting scenarios for the Canon EF16-35mm f/2.8L II USM Lens?

The Canon EF16-35mm f/2.8L II USM Lens is ideal for landscape, architectural, and event photography. Its wide-angle capabilities are perfect for capturing expansive scenes and large groups in tight spaces.

How can I achieve the best focus with this lens?

To achieve the best focus, use the lens's USM (Ultrasonic Motor) for fast and quiet autofocus. For critical focus, especially in low light, switch to manual focus and use live view magnification on your camera.

What should I do if the autofocus is not working properly?

If the autofocus is not working, ensure the lens is securely attached to the camera. Check if the AF/MF switch is set to AF. Clean the lens and camera contacts with a microfiber cloth. If issues persist, consider resetting your camera settings or consulting Canon support.

How do I clean and maintain the Canon EF16-35mm f/2.8L II USM Lens?

To maintain the lens, regularly clean the front and rear elements with a lens blower and microfiber cloth. Avoid touching the glass with your fingers. Store the lens in a dry, dust-free environment, and use a lens cap when not in use.

What is the minimum focusing distance of this lens?

The Canon EF16-35mm f/2.8L II USM Lens has a minimum focusing distance of 0.28 meters (approximately 11 inches), allowing for relatively close-up photography at its widest focal length.

Can I use filters with this lens?

Yes, the Canon EF16-35mm f/2.8L II USM Lens supports 82mm screw-in filters. Using a circular polarizer or ND filter can enhance your images by reducing reflections and controlling exposure.

What are some common issues with the Canon EF16-35mm f/2.8L II USM Lens and how can they be resolved?

Common issues include lens flare and distortion at the widest angles. To minimize these, use lens hoods and correct distortion in post-processing. Additionally, ensure firmware and software are up to date to prevent compatibility issues.

How does weather sealing work on this lens?

The Canon EF16-35mm f/2.8L II USM Lens features weather sealing to protect against dust and moisture. However, it is recommended to use it with a weather-sealed camera body for optimal protection in adverse conditions.

What is the best aperture setting for sharpness with this lens?

For optimal sharpness, use an aperture setting between f/5.6 and f/8. This range provides a good balance of depth of field and sharpness across the frame, minimizing diffraction and aberrations.

How can I prevent vignetting with the Canon EF16-35mm f/2.8L II USM Lens?

Vignetting can be reduced by using a smaller aperture (higher f-number) and ensuring that any attached filters are compatible with wide-angle lenses. Additionally, lens profiles in post-processing software can correct vignetting effects.
