Canon EF 16-35mm f4 L IS USM Lens in mint condition
The Canon EF 16-35mm f/4L IS USM is a high-performance, ultra-wide-angle zoom lens designed for professional photographers and advanced enthusiasts. It is part of Canon's prestigious L-series, known for its superior build quality and optical performance. Here’s an in-depth look at its features and specifications:
Optical Design and Performance
- Lens Construction: The lens comprises 16 elements in 12 groups, including three aspherical lens elements and two Ultra-low Dispersion (UD) elements. These elements work together to minimize chromatic aberrations and distortions, ensuring sharp, high-contrast images across the entire zoom range.
- Aperture: It features a constant maximum aperture of f/4, which allows for consistent exposure settings throughout the zoom range. The aperture is made up of nine rounded blades, contributing to a pleasing bokeh effect in out-of-focus areas.
- Image Stabilization: The lens is equipped with Canon’s Optical Image Stabilizer (IS) technology, providing up to four stops of correction. This feature is particularly useful for handheld shooting in low-light conditions, reducing the risk of camera shake and resulting in sharper images.
Build Quality and Handling
- Construction: As an L-series lens, it boasts a robust build quality with weather-sealing to protect against dust and moisture. This makes it suitable for use in challenging environmental conditions.
- Weight and Dimensions: The lens measures approximately 82.6mm in diameter and 112.8mm in length, and it weighs around 615 grams. Despite its solid construction, it is relatively lightweight and compact for an ultra-wide-angle zoom lens.
- Filter Size: It has a filter thread size of 77mm, allowing for the use of various filters such as polarizers and ND filters to enhance your photographic creativity.
Autofocus and Manual Focus
- Autofocus System: The lens features a ring-type Ultrasonic Motor (USM) for fast, precise, and virtually silent autofocus. This makes it ideal for both still photography and video recording.
- Full-Time Manual Focus: Even when the autofocus is engaged, photographers can make fine adjustments manually without switching modes, thanks to the full-time manual focus capability.
Versatility and Applications
- Focal Length Range: With a focal length range of 16-35mm, this lens is incredibly versatile. It is perfect for landscape photography, architecture, interior shots, and even astrophotography. The ultra-wide-angle perspective allows photographers to capture expansive scenes and dramatic perspectives.
- Close Focusing Distance: The lens has a minimum focusing distance of 0.28 meters (11 inches), enabling close-up shots with a maximum magnification of 0.23x. This is particularly useful for capturing detailed foreground elements in wide-angle compositions.
Coatings and Lens Hood
- Lens Coatings: Canon has applied Super Spectra Coating to reduce flare and ghosting, ensuring high contrast and color fidelity. Additionally, a fluorine coating on the front and rear elements helps to repel water, oil, and other contaminants, making the lens easier to clean.
- Lens Hood: The lens comes with a petal-shaped lens hood (EW-82) that helps to prevent stray light from causing flare and also provides some protection to the front element.
Conclusion
The Canon EF 16-35mm f/4L IS USM is a top-tier lens that combines excellent optical performance, robust build quality, and advanced features like image stabilization and a constant f/4 aperture. It is a reliable choice for photographers who need a versatile, high-quality ultra-wide-angle zoom lens for a variety of shooting scenarios. Whether you are capturing sweeping landscapes, intricate architectural details, or dynamic street scenes, this lens delivers outstanding results with every shot.
