Canon EF-S55-250mm f 4-5.6 IS STM Specification

The Canon EF-S 55-250mm f/4-5.6 IS STM Lens is a versatile telephoto zoom lens designed for APS-C format Canon EOS DSLR cameras. It offers a focal length range equivalent to 88-400mm in 35mm format, making it ideal for capturing distant subjects, wildlife, and sports. The lens features a variable aperture ranging from f/4 at the wide end to f/5.6 at the telephoto end, allowing for flexibility in various lighting conditions.

Incorporating Canon’s STM (Stepping Motor) technology, the lens provides smooth and near-silent autofocus, which is particularly beneficial for video recording. The Image Stabilization (IS) system compensates for camera shake, offering up to 3.5 stops of correction to produce sharper images in low light or at longer focal lengths. The optical construction consists of 15 elements in 12 groups, including one Ultra-Low Dispersion (UD) element, which helps to minimize chromatic aberrations and enhance image clarity.

The lens design includes a seven-blade circular aperture that contributes to a pleasing bokeh effect, enhancing the aesthetic quality of out-of-focus areas. The minimum focusing distance of 0.85 meters allows for close-up photography with a maximum magnification of 0.29x. Additionally, the lens is compact and lightweight, measuring approximately 111.2mm in length and weighing around 375 grams, making it convenient for travel and handheld shooting. The Canon EF-S 55-250mm f/4-5.6 IS STM Lens is an excellent choice for photographers seeking a reliable and affordable telephoto zoom option with advanced features for both stills and video.

Why is my Canon EF-S55-250mm f/4-5.6 IS STM lens not focusing properly?

Ensure the lens is set to AF mode. Check for obstructions on the lens and ensure that there is adequate lighting. If issues persist, clean the lens contacts and try again.

Can I use the Canon EF-S55-250mm f/4-5.6 IS STM lens with a full-frame camera?

No, the lens is designed for APS-C sensor cameras. Using it on a full-frame camera can cause vignetting.

How can I achieve a blurred background effect with the Canon EF-S55-250mm f/4-5.6 IS STM lens?

Use a longer focal length, a wider aperture, and position your subject far from the background to achieve a shallow depth of field.

What is the function of the Image Stabilizer on the Canon EF-S55-250mm f/4-5.6 IS STM lens?

The Image Stabilizer helps reduce camera shake when shooting handheld, especially at slower shutter speeds, leading to sharper images.

How should I store my Canon EF-S55-250mm f/4-5.6 IS STM lens when not in use?

Store the lens in a cool, dry place with the lens caps on to protect the glass. Consider using a padded lens case for additional protection.

What should I do if the zoom ring on my Canon EF-S55-250mm f/4-5.6 IS STM lens is stiff?

Gently rotate the zoom ring back and forth to work out any stiffness. If the problem persists, seek professional cleaning or repair services.

Why do my images appear soft when using the Canon EF-S55-250mm f/4-5.6 IS STM lens?

Ensure the lens is properly focused and check the shutter speed to avoid motion blur. Using a tripod can also help achieve sharper images.

How can I update the firmware of the Canon EF-S55-250mm f/4-5.6 IS STM lens?

Canon lenses typically do not have user-updateable firmware. For updates, check Canon's official support channels or contact a service center.
