![]() ![]() Sigma appends the model names with an S for Sport or a C for Contemporary, so officially speaking I’m reviewing the 150-600mm f5-6.3 DG OS HSM | S. While the full specification and price of the Contemporary model were not known at the time of writing, the dual-offering remains a cunning approach by Sigma, allowing the cheaper version to compete with Tamron and the pricier one to go up against premium options from Canon and Nikon. The higher-end Sport version reviewed here is fully weather-sealed, while the more affordable Contemporary version, yet to be released, employs a simpler optical construction and sealing at the mount to hit a lower price point. Both share the same 150-600mm f5-6.3 specification, but have different levels of quality, construction and sealing. Interestingly, Sigma is replacing the 150-500mm with not one, but two new lenses. It also now allows Sigma to compete on range with the existing Tamron 150-600mm f5-6.3. Announced in September 2014, it replaces the earlier 150-500mm f5-6.3, extending its reach while also offering higher performance and tougher build. The Sigma 150-600mm f5-6.3 DG OS HSM Sport is a super-telephoto zoom lens, available in Canon, Nikon and Sigma mounts, and corrected for full-frame use. Alternatively get yourself a copy of my In Camera book or treat me to a coffee! Thanks! Buy it now! Check prices on the Sigma 150-600mm Sport at Amazon, B&H, Adorama, or Wex. Compare closely with Tamron's 150-600mm and Sigma's own cheaper Contemporary version. There may be vignetting and evidence of coloured fringing, but both are easily corrected in RAW conversions, and importantly the lens delivers where it should with fine, well-resolved details right into the corners of full-frame images. And the optical quality in my tests proved to be very respectable across the entire range. The AF, when coupled with a decent DSLR, is fast, confident and very usable for sports. The build quality is excellent: it's heavy, but reassuringly built with full weather sealing. ![]() The zoom lock switch can be engaged at any zoom setting that has a marked focal length.Summary Sigma's 150-600mm Sport is a highly desirable lens for sport and wildlife photographers who demand a super-telephoto reach without the stratospheric cost of big primes, or even the highest-end zooms from Canon and Nikon. The 150-600mm Contemporary lens isn’t as extensively weather-sealed as the Sports edition but still has a rubber gasket on the mounting plate, along with fluorine coatings on the front and rear elements to repel moisture and greasy fingermarks. These can be set up with Sigma’s optional USB Dock, to tailor various functions like how visible stabilization is in the viewfinder, and the speed of autofocus. Despite the price drop from Sports line lenses, you still get the full range of switchable dual autofocus, giving priority to either AF or manual override, an AF range limiter, dual-mode optical stabilization for static and panning shots, and two switchable custom modes. Posh glass includes one top-grade FLD (‘Fluorite’ Low Dispersion) element and three SLD (Special Low Dispersion) elements. Although designed with an eye on the price tag, the budget-friendly Sigma boasts an impressive feature list. ![]()
