I was able to test this lens out at Photo plus before I purchased it. I tested it against a Canon 100-400 L mk II at matching focal lengths and apertures. The sigma lens was able to resolve more detail, so I bought one. Absolutely phenomenal performance since I purchased it.

The Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports is a versatile 10x telephoto zoom lens for full-frame DSLR cameras, and APS-C sensor cameras with an effective increase in focal length. It's actually the world's first 10x optical zoom telephoto lens with a tele end of 600mm.

Waited for the UK release of this lens, having used the 1t0-600mm C lens in the past. This one is much faster focusing, with an extra 90mm focal length at the short end & the added bonus of a built in macro lens when @ 200mm. It is heavy, but the build quality is the reason why. Can't fault it.

Of course, not everyone has $2,000 available for a lens. If your budget is a bit tighter, don't forget about the Tamron 150-600mm G2 , or our favorite affordable option, the Sigma 150-600mm Contemporary.

10x zoom power; Superb fit and finish; Weather sealing and fluorine coating; Strong optical stabilization; Available for Canon, Nikon, and Sigma cameras

Heavy; Big zoom sacrifices image quality versus shorter designs; Requires adapter for use with mirrorless systems

Sigma's new 60-600mm f/4.5-6.3 DG OS HSM Sports zoom lens delivers in a big way. Among all lenses that reach 600mm it has the greatest zoom range at 10X. This potent professional tool has a few surprise features, too.

In the actual Sigma's offer you can observe a transition toward 60-600 mm and 150-600 mm models and in the case of the latter we have two devices, one Contemporary and one Sport, already available and the following charts stacks these three lenses up against each other.

very solid; weather-sealed casing; excellent image quality in the frame centre across the whole range of apertures and focal lengths; good performance on edge of APS-C/DX sensor; completely acceptable resolution on edge of full frame; low longitudinal chromatic aberration; lack of problems with...

distinct lateral chromatic aberration at 60 mm focal length; weak performance against bright light; too high vignetting on full frame

The specification for the Sigma 60-600mm f/4.5-6.3 DG OS HSM | Sports doesn't sink in straight away. It looks and sounds like the company's popular 150–600mm f/5-6.3 DG OS HSM | Sports lens, but this new model's shorter minimum focal length is the killer feature here.

Overarching every other feature of the Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens is the extreme focal length range it provides. Everyone loves a lens deemed the world's first and this one, according to Sigma, receives that designation for being the first 10x optical zoom telephoto...

It's a big, heavy lens, but the Sigma 60-600mm weighs in with some seriously impressive performance and versatility. Considering its fair pricing, this is a seriously tempting lens for shooting wildlife close and far. Super-telephoto meets superzoom in this lens.

Huge focal length versatility; Rugged weather-sealed build; Impressive sharpness

Very heavy; Noticeable distortion at 60mm

The Sigma 60-600mm f4.5-6.3 DG OS HSM Sports is an exemplary lens in the hands of the right photographer. With lightning-fast autofocusing capabilities, near diamond standard build quality, and images well worth their weight in a print, this lens is the one that many photographers should reach for.
