Optical Design and Build
- Lens Construction: The lens comprises 16 elements in 12 groups, including three aspherical elements. These elements help to minimize distortions and aberrations, ensuring high image quality with excellent sharpness and contrast across the zoom range².
- Aperture: It features a constant maximum aperture of f/2.8, which allows for significant light intake, making it suitable for low-light conditions. The aperture is constructed with 7 rounded blades, contributing to a pleasing bokeh effect².
- Coatings: Canon's Super Spectra coatings are applied to reduce ghosting and flare, ensuring high contrast and color fidelity even in challenging lighting conditions².
Autofocus and Manual Focus
- Autofocus: The lens utilizes a Ring-type Ultrasonic Motor (USM) for fast, precise, and quiet autofocus. Full-time manual focus override is available, allowing for fine adjustments without switching out of AF mode³.
- Internal Focusing: The internal focusing mechanism ensures that the lens does not change in length during focusing, which helps maintain balance and handling³.
Physical Characteristics
- Dimensions and Weight: The lens measures approximately 3.5 inches in diameter and 4.4 inches in length, weighing around 1.4 pounds (635 grams). This makes it relatively compact and lightweight for an ultra-wide-angle zoom lens².
