I find that Sigma's brushes never seem to stop shedding, or I just have a bad bunch. Also they aren't very good at picking up a product. I have an angled contour brush from both MAC and Sigma, and the MAC one is just so dense and really picks up a lot of product, where the Sigma one is the complete opposite of the MAC. The Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary ($1,089) is a big, heavy lens. But that's no surprise when you consider its maximum reach, full-frame sensor coverage, and sturdy build.
By connecting a SIGMA Art, Contemporary, or Sports lens to a computer with the SIGMA USB DOCK, photographers can update the lens firmware and adjust focus position and other parameters. Exclusive SIGMA Optimization Pro software makes customization easy. It is possible to select the autofocus speed and adjust the focus limiter and Optical Stabilizer (OS) function.
Special Software “SIGMA Optimization Pro” will offer the following customization.
