Designed for APS-C sensor DSLR cameras, this lens covers a focal range equivalent to 27-75mm in full-frame format, ideal for portraits, landscapes, street photography, and everyday scenes. Its maximum aperture of f/2.8 throughout the zoom range allows you to work in low light and achieve a nice background blur, while its macro capability with a minimum focusing distance of 0.2 meters brings you closer to the smallest details.
This second-hand unit has been inspected by our technical team and comes with Camera Market's 6, 12, or 24-month warranty, so you can buy with complete peace of mind. Its lightweight construction (450 grams) and autofocus make it a comfortable and agile travel companion. Keep in mind that this lens was released in 2006, so its optical performance is typical of its era, but it remains a very capable tool for exploring your creativity. For exact technical specifications, we recommend checking the manufacturer's datasheet.
