If you’ve been serious about photography for any length of time, you’ve probably learned that there’s more to gear ownership than your equipment being awesome right out of the box. It’s durability and performance must stand the test of time.
To that end, many manufacturers in the industry make it a priority to preserve value of your investment by offering ongoing support of their products. Firmware updates, such as Sigma’s latest batch aren’t always major but, like any finely tuned instrument, keep your Sigma gear operating at peak performance. Let’s look at what it offers.
This firmware allows compatibility with Canon’s in-camera Lens Aberration Correction function to enable correction matching the optical characteristics of each lens. It also corrects the phenomenon that abnormal images appear or operation errors occur when the function is enabled.
This firmware also corrects the phenomenon whereby the continuous shooting speed decreases in certain combinations with some cameras when used with the 14-24mm F2.8 DG HSM | Art for Canon, and the phenomenon whereby the AF speed occasionally becomes unstable when used with the 100-400mm F5-6.3 DG OS HSM | Contemporary for Canon.
For customers who own the SIGMA USB DOCK and applicable products listed below, please update the firmware via SIGMA Optimization Pro.
