- Zoom lens with vast zooming range.
- Has a solid build using metal and hard elements alloys.
- Provides beautiful image stabilization for movement and static shots, and thus can be taken handheld.
- The lens provides beautiful results with the short distance setting.
The Sigma 60-600mm f/4.5-6.3 DG OS HSM is a zoom lens in the Sigma Sports series. These lenses are expensive and more cumbersome when compared with the contemporary series of lenses, but they are built tough to last. Concerning their weight, they are more robust and more stable. The lens constituents are no fewer than 25 lens elements in 19 groups.
Sigma has improved the image stabilization factor with these lenses. Stabilization yields up to four stops. The shortest zoom setting is 60mm. At this stage, the Sigma 60-600mm f/4.5-6.3 DG OS HSM has the maximum aperture and minimum f-stop of f/4.5, which is a bit limiting in how much light is available. The f-stop at the maximum focal length of 600mm is f/6.3, which is a standard value for the amount of zoom produced.
The 10x wide range of focal length means the user doesn’t need to change lenses for various focal lengths. This can be a handy tool for capturing wildlife.
The Sigma 60-600mm f/4.5-6.3 DG OS HSM is a big player. Sigma has done everything possible to reduce and limit its weight and the lens comes in at about 2700 grams. The lens hood and the lens parts are made of carbon-reinforced plastics, and the complete inner tube is made of Thermally Stable Composite (TSC), a high quality graded plastic. The rear part and the tripod base is made of magnesium alloy. The mount is made of bronze. When compared to other telephoto lenses, this weighs considerably less. The length is 269mm, and the diameter is 120mm. The filter size is vast at 105mm.
The lens contains gaskets around the moving parts and makes it weather-resistant. The front element has a coating to ward off moisture, dirt, and grease. The lens has two large rings; the front one is for zooming. The other rear ring is the focus ring. The stroke of the range is about 100 degrees; the turn is smooth and easy.
The lens also has switches for focus, focal range, image stabilization, and two custom modes. The two modes can be programmed using the Sigma USB facility. The focuser can be either auto or manual. The autofocus motor works faster and smoother, making focal transitions elegant and straightforward. You can adjust the autofocus manually. The range of the autofocus can be limited to from 60cm to six meters, from six meters to infinity, or you can, of course, choose “full” for the whole range.
The tripod collar turns and clicks at every 90 degrees. The base is replaceable and contains an Arca Swiss profile, so additional screw coupling is not necessary underneath. The ring of the collar has two eyes for attaching the strap. A nine-blade aperture with rounded lamellae ensures a beautiful bokeh. At higher focal lens, bokeh formation is quite natural and comfortable.

The image quality of the Sigma 60-600mm f/4.5-6.3 DG OS HSM is excellent. The sharpness in the center is reasonably good at full aperture, and when stopping down two or more stops, the center sharpness gets even better. The corners lack image quality when compared to the center at the shorter focal lengths. But for larger focal lengths for which these lenses are generally used, the quality is great.
At the extreme zoom positions, the difference between the corners and the center becomes smaller, but the total sharpness is affected. This is quite common for longer lenses. The 600mm shots are outstanding. The measured values are reasonably good. The image quality is very appealing. The distortion is very low. In jpeg, it runs from somewhat barrel-shaped at 60mm via neutral between 100 and 200mm to slightly pincushion-shaped at 600mm. But this effect is visible only in very critical architectural shots.
The Sigma 60-600mm f/4.5-6.3 DG OS HSM comes with image stabilization. Hand stabilization is not sufficient for taking photographs with longer lenses. The optical stabilization (OS) of the sigma is very lovely. Four stops variation is feasible and gives a great result. There is a switch to choose three modes of image stabilization on the lens. Mode 1 contains the omnidirectional image stabilization. Mode 2 takes into account the movement of the lens in a particular direction. This mode best suits a pan shot with a moving subject or if you’re using a dolly.
The Sigma 60-600mm f/4.5-6.3 DG OS HSM is a huge zoom lens providing a great variant of focal lengths. A zoom range from standard to extreme or super telephoto can be used, making this lens unique. The brightness at 60mm may not be high, but this doesn’t make much of a difference when compared to other lenses. The entire picture quality is decent, and the lens is built to be used under all circumstances mainly for wildlife photography, which warrants the requirement of large focal length lenses.
