Canon Ef-s 15-85mm Vs Sigma 17-70mm

Choosing the right lens is crucial for any photographer, and the decision between the Canon EF-S 15-85mm and Sigma 17-70mm is a common dilemma for Canon DSLR users. Both lenses offer versatile focal lengths, making them suitable for various photography styles. In this comprehensive guide, we will delve into the key differences between these two lenses to help you make an informed decision.

Focal Length and Aperture

The Canon EF-S 15-85mm boasts a wider focal length range (15-85mm) compared to the Sigma 17-70mm (17-70mm). This wider range provides greater flexibility, allowing you to capture both wide-angle shots and telephoto shots with a single lens. However, the Sigma 17-70mm offers a slightly wider maximum aperture (f/2.8) compared to the Canon EF-S 15-85mm (f/3.5-5.6). This means that the Sigma lens can produce brighter images in low-light conditions or allow for shallower depth of field.

Image Quality

Both the Canon EF-S 15-85mm and Sigma 17-70mm produce sharp and detailed images. However, the Canon lens has a slight edge in terms of image quality, especially at the wider end of the zoom range. It delivers excellent contrast and color reproduction, while the Sigma lens tends to exhibit some chromatic aberration at certain focal lengths.

Autofocus Performance

The Canon EF-S 15-85mm uses Canon’s Ultrasonic Motor (USM), which provides fast and silent autofocus. The Sigma 17-70mm, on the other hand, employs a Hyper Sonic Motor (HSM), which is also known for its speed and accuracy. Both lenses perform well in low-light conditions and track moving subjects effectively.

Build Quality and Weather Resistance

The Canon EF-S 15-85mm is constructed from high-quality materials and features a weather-resistant design. It can withstand dust and moisture, making it suitable for outdoor photography in adverse conditions. The Sigma 17-70mm is also well-built but does not offer the same level of weather resistance as the Canon lens.

Size and Weight

The Canon EF-S 15-85mm is slightly larger and heavier than the Sigma 17-70mm. The Canon lens weighs approximately 575 grams, while the Sigma lens weighs around 465 grams. This difference in size and weight may be a consideration for photographers who prioritize portability.

Price and Availability

The Canon EF-S 15-85mm is typically more expensive than the Sigma 17-70mm. However, both lenses are widely available from various retailers and online stores. The price may vary depending on factors such as the specific model and bundle options.

Which Lens Is Right for You?

The choice between the Canon EF-S 15-85mm and Sigma 17-70mm ultimately depends on your individual needs and preferences. If you prioritize image quality and weather resistance, the Canon lens is the better option. However, if you prefer a wider maximum aperture and a more compact design, the Sigma lens may be a suitable choice.

Versatile Zoom for All Occasions

Both the Canon EF-S 15-85mm and Sigma 17-70mm are excellent lenses that offer versatility and performance for aspiring photographers. The Canon lens provides a wider focal length range and superior image quality, while the Sigma lens offers a wider maximum aperture and a more compact design. Consider your specific requirements and budget to make the best decision for your photography journey.
