Design and Build Quality
Sigma has long been known for its solid build quality, and the 2470mm F2.8 DG DN continues this tradition. The lens is crafted with a lightweight aluminum and thermally stable composite plastic body that exudes durability without sacrificing portability. Weighing approximately 835g (1.84 lbs), it strikes an excellent balance for those who need a reliable workhorse without the heft of some of its competitors.

Optical Performance
Sigma’s reputation for optical excellence shines with this lens, incorporating advanced elements to minimize optical aberrations. The 2470mm F2.8 DG DN features a total of 19 elements in 15 groups, including three SLD (Special Low Dispersion) elements and one aspherical element. This sophisticated combination helps to control distortion and chromatic aberration, resulting in stunning image clarity and color accuracy.
With a constant maximum aperture of F2.8 throughout the zoom range, the lens excels in lowlight conditions, allowing photographers to maintain creative control over depth of field. Whether capturing dramatic landscapes at dusk or soft portraits with a bokeh background, this lens is sure to deliver.
