Just posted: Sigma 150-600mm f/5-6.3 DG DN OS Sports Lens Review.
This lens is a great option for wildlife and sports.
I usually post reviews in the morning, but this day went a bit sideways. We had a tremendous storm this afternoon, with extreme wind (wind shear or perhaps a small tornado), hail, and a huge amount of rainfall in a short period of time. In the storm's path are trees down, and with them, the power went down. The laptop battery and UPS are still up, so I'm sharing the review now.
