Here are the key tech specs for the Canon EF 16-35mm f/2.8L II USM:

Key Specifications:

General Information:

• Lens Type: Wide-Angle Zoom Lens

• Mount: Canon EF lens mount (compatible with both full-frame and APS-C sensor Canon DSLR cameras)

• Series: Canon L-Series (Luxury series), designed for professional use with superior image quality and durability

• Focal Length:

  • 16mm to 35mm (wide-angle to standard zoom)

• Maximum Aperture: f/2.8 (constant aperture throughout the zoom range)

• Minimum Aperture: f/22

Optical Design:

• Lens Elements: 16 elements in 12 groups

• Special Elements:

  • 2 x Ultra-low Dispersion (UD) elements: These help reduce chromatic aberration and ensure high contrast and sharpness across the frame.

  • 1 x Aspherical element: To reduce distortion and spherical aberration, improving overall sharpness.

  • Subwavelength Structure Coating (SWC): Canon's proprietary coating that minimizes flare and ghosting, especially useful in backlit conditions.

Autofocus and Performance:

• Autofocus Motor: Ultrasonic Motor (USM) – Fast, silent, and accurate autofocus with full-time manual focus override.

• Focus Type: Internal focus (the lens does not change in length when focusing, which helps maintain balance)

• Minimum Focus Distance: 0.28 meters (0.92 feet) – allows close focusing for wide-angle shots.

• Focus Distance Indicator: Yes (for manual focus use)

• Full-Time Manual Focus: Yes (you can adjust focus manually even while the lens is in autofocus mode)

Build and Durability:

• Weather Sealing: Yes (dust and moisture-resistant, making it suitable for outdoor and professional use in challenging environments)

• Filter Size: 77mm (standard filter size for this lens)

• Lens Hood: EW-83E (petal-shaped lens hood), included to minimize flare and protect the lens

• Dimensions: 88.5 mm x 123.5 mm (3.5 inches x 4.9 inches)

• Weight: 650 g (1.43 lbs)

Image Quality:

• Distortion: The lens features minimal distortion, especially when zoomed in at the longer end, but some barrel distortion may be noticeable at 16mm.

• Sharpness: Outstanding sharpness across the frame, especially when stopped down slightly. It performs exceptionally well at f/2.8 throughout the zoom range.

• Bokeh: Due to its rounded 9-blade aperture, the lens produces smooth bokeh (out-of-focus areas), particularly at wider apertures (f/2.8).

Compatibility:

• Full-Frame Compatibility: Yes, it is fully compatible with Canon full-frame DSLRs (e.g., Canon 5D, 6D, 1D series).

• APS-C Compatibility: Yes, when used with APS-C sensor cameras (e.g., Canon 90D, 7D series), the effective focal length will be approximately 25.6mm to 56mm (due to the crop factor of 1.6x).

Additional Features:

• Zoom Lock: The lens features a zoom lock to prevent zoom creep when carrying the lens at the shorter focal length (16mm).

• Lens Construction: L-series construction for durability, with high-quality materials designed to withstand professional use in demanding environments.

Notable Features:

• Fast, Constant Aperture: The f/2.8 aperture across the zoom range provides excellent low-light performance and better control over depth of field compared to variable aperture zoom lenses.

• High Image Quality: The combination of advanced optical elements, coatings, and Canon’s quality control ensures that the lens produces sharp, high-contrast images with minimal chromatic aberrations, distortion, and flare.

• Professional Build: Weather-sealing and solid construction make the lens a reliable option for outdoor, travel, and professional photographers who need a lens that can handle challenging conditions.

Ideal For:

• Landscape Photography: The wide field of view and sharpness across the frame make it ideal for capturing expansive landscapes.

• Architecture: The minimal distortion and wide aperture make it great for shooting buildings, interiors, and other architectural subjects.

• Astrophotography: With its wide aperture and excellent performance in low light, it is often used for night sky and star photography.

• Event and Wedding Photography: Its wide focal range and constant f/2.8 aperture provide flexibility and good low-light performance for events.
