What is 18-135mm lens canon?

The Canon 18-135mm lens is a versatile zoom lens that is a popular choice for both beginner and experienced photographers. Here's a breakdown of key information:

• Focal Length: 18-135mm provides a wide range, making it suitable for various subjects from landscapes (18mm) to portraits and moderate telephoto shots (135mm). This focal%20length range is a key selling point.

• Aperture: Typically, it features a variable aperture, often f/3.5-5.6. This means the maximum aperture changes as you zoom. At 18mm, the widest aperture is f/3.5, and at 135mm, it narrows to f/5.6. A wider aperture (lower f-number) allows for more light and shallower depth of field.

• Image Stabilization (IS): Many versions include Image Stabilization to reduce camera shake, particularly useful at longer focal lengths and in low light. The effectiveness of the image%20stabilization system varies between models.

• STM (Stepping Motor): Some versions use a Stepping Motor (STM) for quiet and smooth autofocus, making them well-suited for video recording. STM lenses are preferred for their silent operation during video.

• USM (Ultrasonic Motor): Older versions might utilize a Ultrasonic Motor (USM) for fast and accurate autofocus, although this can be louder than STM.

• EF-S Mount: It's designed for Canon's EF-S%20mount, meaning it's compatible with Canon crop-sensor (APS-C) DSLRs like the Rebel series, EOS 7D series, and EOS 80D/90D. It cannot be used on full-frame Canon cameras.

• Image Quality: Offers good image quality for its price range. While not as sharp as professional-grade lenses, it provides a significant step up from basic kit lenses.

• Build Quality: Typically features a plastic construction, making it lightweight but not as robust as more expensive lenses.

• Applications: Versatile lens suitable for travel, everyday photography, family events, landscapes, and portraits. It's a great all-in-one option, reducing the need to switch lenses frequently.

• Versions: There are several variations, including the original EF-S 18-135mm f/3.5-5.6 IS, the EF-S 18-135mm f/3.5-5.6 IS STM, and the EF-S 18-135mm f/3.5-5.6 IS USM.
