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

It has a range of focal length from 170mm to 500mm, making it a great choice for wildlife and sports photography. The lens is made up of 13 elements in 11 groups, including one Special Low Dispersion (SLD) glass element to reduce chromatic aberration. The lens also has a multi-layer lens coating to reduce ghosting and flare.

The lens can be used in both autofocus and manual focus modes, giving you more control over your shots. The build quality of the lens is good, making it durable and long-lasting.

The bokeh or background blur of the lens is decent, but not the best in its class. The aperture ranges from f/5 to f/6.3, which is not very wide, but can still produce good results in bright conditions.

The manufacturing time of the lens is not specified, but it has been around for a while and is still a popular choice for photographers. The resolution of the lens is good, but not as sharp as some of its more expensive alternatives.

Overall, the Sigma DG 170-500mm f/5-6.3 APO lens is a good choice for photographers looking for a super telephoto zoom lens with decent optics and build quality.

Sure, I’d be happy to enrich this review of the Sigma DG 170-500mm f/5-6.3 APO camera lens:

Positives:

This lens offers an incredible range for its cost, making it an excellent option for a photographer on a budget who is looking to shoot wildlife or sports at a distance. It also has a solid build quality, with a weight that feels substantial in the hand. Despite some of its flaws, it still manages to produce relatively sharp images at f/8 and above, and the APO (Apochromatic) design helps minimize chromatic aberration.

Negatives:

One of the main drawbacks of this lens is that it can be quite soft at its widest aperture, especially on the longer end of the zoom range. Additionally, the autofocus system can be slower than other, more expensive lenses, which may cause some frustration for photographers who shoot fast-moving subjects. Lastly, the lens can sometimes struggle to produce contrasty images, which may require some post-processing to fix.

Conclusion:

Overall, the Sigma DG 170-500mm f/5-6.3 APO is an excellent lens for the price, offering a fantastic range and a solid build quality. While it may have some flaws, these are relatively minor compared to the lens’s overall capabilities. So if you’re a photographer on a budget who’s looking for a versatile telephoto lens, this could be a great option to consider.
