Dustin Abbott gives us the final breakdown review of the Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens. He also give us action test shots compared against the high quality Canon 100-400mm L II lens.
Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind.
All-new optical stabilizer (OS) unit with exclusive algorithm
Featuring a newly developed gyroscopic sensor and a new and exclusive algorithm, the all-new OS unit provides a powerful stabilization effect. An acceleration sensor detects camera shake in any direction-horizontal, vertical, or diagonal. This technology allows the OS to stabilize the image very effectively, regardless of whether the camera is being held in horizontal or vertical orientation.
Nikon electromagnetic diaphragm mechanism included
The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting. Note: Functionality may be limited on some camera bodies.
