![]() ![]() The “full” position will often not lock on to closer subjects. The biggest must-know is that focus limiter switch. Take it out on a date first before you jump into an important shoot. The extra dials and controls here mean this lens is best after you take a little time to get to know it. The subject, for this test, was kids on a sledding hill. I had about a 25 percent miss rate for action heading straight towards the camera. That said, it’s hard to point fingers at whether the autofocus misses are from the lens, the body, or the simple physics of moving such a large number of lens elements quickly. We’ve noted some focusing issues from the L-Mount before, and noted in our S5 review that autofocusing was better with Panasonic lenses. The S5 isn’t my favorite body for fast focusing - I think Canon and Sony are both quite a bit faster. Where the R3 can lock onto the black eye of a black-capped chickadee, the S5 locks onto the bird body and is often thrown off when branches are in the way. The S5 definitely has a place, but I don’t think it’s in the top three for sports and wildlife cameras. Going from the R3 to the S5 feels a bit like trading in a convertible for a minivan, complete with Goldfish crumbs in every crevice. The last combo I used for wildlife before this was the Canon EOS R3 and the 70-200mm f4. But, there are 25 lens elements to move across a pretty big range, and it doesn’t always keep up with the action on the S5. It can focus at an impressive 22.8 inches away at 150mm. Additionally, a magnesium tripod socket with a removable foot and 90° click stops provides a sturdy support option.The Sigma 150-600mm uses a magnetic sensor to improve the speed and accuracy of the autofocus by detecting precisely where the focusing lens element is. ![]() ![]() Barrel construction consists of aluminum and TSC (Thermally Stable Composite) for an ideal combination of toughness and improved portability. A dust and splash resistant structure protects the lens against water and dust intrusion, and a water and oil repellant coating on the front element resists moisture and fingerprints. Additional on-lens controls include a Focus Limiter switch, OS Mode switch, Custom switch for custom OS settings, and three customizable AFL buttons.Īs part of the Sigma Global Vision Sports line of lenses, the 150-600mm f/5-6.3 DG DN OS Sports Lens is specifically designed for everyday use in challenging conditions. A new Zoom Torque switch gives users the option to adjust the level of zoom ring resistance from Lock (locked at the wide end for transport), Tight (prevents zoom creep), and Smooth (for easy, smooth zooming). Optical image stabilization delivers approximately four stops of compensation, with two standard OS modes for both handheld shooting and panning situations. An updated and redesigned autofocus system offers both speed and precision by incorporating an AF actuator driven by a stepping motor, as well as a high-precision magnetic sensor. This lens provides high rendering throughout the entire zoom range at all apertures, and ghosting, flare, and various types of aberrations are all well controlled. Deal for wildlife, sports, landscapes, motorsports, and countless other photographic endeavors, the 150-600mm f/5-6.3 DG DN OS Sports Lens from Sigma offers the features and image quality that professionals demand. ![]()
