Canon EF-S 10-22mm f/3.5-4.5 USM Lens

Wide Zoom Range (10-22mm)

• The 10-22mm focal length offers a true ultra-wide-angle perspective, perfect for capturing expansive landscapes, cityscapes, architecture, and tight interior spaces. On APS-C cameras, the effective focal length is approximately 16-35mm due to the crop factor.

2. Aperture (f/3.5-4.5)

• The lens features a variable aperture, with f/3.5 at the 10mm wide end and f/4.5 at the 22mm end. While not a constant aperture, it provides a bright enough opening for wide-angle shots in most lighting conditions.

3. Ultrasonic Motor (USM)

• The USM (Ultrasonic Motor) delivers fast, accurate, and nearly silent autofocus. This is particularly useful for video recording, where silent autofocus is important for smooth audio, and it also helps in ensuring quick focusing for still photography.

4. Optical Design

• The lens incorporates advanced lens coatings and optics that help minimize chromatic aberrations, distortion, and flare. This ensures sharp, clear, and high-quality images even at wide apertures and at the extreme ends of the zoom range.

5. Compact and Lightweight

• Despite being an ultra-wide zoom lens, the EF-S 10-22mm is relatively compact and lightweight, making it an excellent choice for travel, handheld shooting, or as part of a lightweight lens kit.

6. Minimum Focusing Distance (9.4 inches / 24 cm)

• The lens has a short minimum focusing distance, allowing you to capture wide-angle close-up shots, making it great for environmental portraits or creative wide-angle compositions with subjects close to the camera.

7. Circular Aperture (7 Blades)

• The seven-blade circular aperture helps create smooth and aesthetically pleasing background blur (bokeh), which can be useful in isolating subjects from their background when shooting at close range.

8. Compatible with APS-C Sensor Cameras

• This lens is designed for APS-C sensor Canon DSLR cameras, where it provides a focal length equivalent to approximately 16-35mm, making it ideal for wide-angle photography on these bodies.
