Sigma AF 170-500mm f/5-6.3 APO

The lens has a range of focal lengths from 170-500mm, which is suitable for wildlife, sports and other distant subjects. It has an APO (Apochromatic) lens element which reduces chromatic aberrations, resulting in sharper images. The lens coating helps to minimize flare and ghosting. It has both autofocus and manual focus options. The build quality is good, and it is made with durable materials. The resolution is good, and the bokeh (background blur) is decent. The lens was manufactured some time ago, but it still performs well and is a good alternative to other lenses in this range.

Optical design

Not the best in low light conditions but the lack of high aperture can be compensated with higher iso Has 9 aperture blades, with this amount of aperture blades you will be satisfied with the result.
