The OS system has two modes - mode 1 is suitable for general photography, and mode 2 is best for panning shots. A clear distance scale in both feet and meters runs from the closest focusing distance of 1.2m to infinity.īuilt-in vibration reduction is activated by the Stabilizer switch on the lens barrel, which offers around 3.5 stops of compensation. The focus limiter switch has two settings, 1.2m-infinity and 2.5m-infinity, which helps speed up the auto-focusing if you know how far your subject is from the lens. It's also a very quiet performer, thanks to the built-in ring-type USM (Ultra Sonic Motor). We didn't experience very much "hunting" at all, either in good or bad light, with the lens accurately focusing virtually all of the time. When it comes to auto-focusing, this lens is a very quick performer, taking about 0.10 seconds to lock onto the subject when mounted on the Canon EOS 5DS R that we tested it with. Polariser users should be pleased that the 77mm filter thread doesn't rotate on focus. There are hard stops at both ends of the range, making it easier to set focus at infinity. The Canon EF 70-200mm F2.8L IS III USM lens has a very generously sized focus ring, which is ridged for easier grip.

The 23 elements in 19 groups are made of high-grade glass with one fluorite element and five ultra-low dispersion glass elements. The lens has a non-retractable design, so it does not extend at all when zoomed out from 70mm to 200mm.īuild quality is excellent, with a weather-resistant design that protects the lens from dust and moisture and fluorine-coated front and rear elements which are easy to clean.
Note that the focal length will also change, becoming 112-320mm, although some may users regard this as a positive.Īs demonstrated by the product images below, it's a much better match for a professional-grade, full-frame camera like the Canon EOS 5DS R that we tested it with, where it feels better balanced, although we'd still suggest fitting a battery grip to that camera too for more protracted use. While you can use it on a smaller APS-C body, the EF 70-200mm F2.8L IS III USM won't balance particularly well unless you attach a battery grip to the camera. It's about the same size as the Tamron SP 70-200mm F/2.8 Di VC USD G2 and noticeably lighter than the Sigma 70-200mm f/2.8 DG OS HSM Sports lenses.
