Sigma 10-18mm f/2.8: Best APS-C wide angle lens!

Buy the Sigma 10-18mm f/2.8 at https://SDP.io/S1018 Tony Northrup reviews the Sigma 10-18 f/2.8 super-wide angle lens for APS-C mirrorless cameras such as the Canon R100, R50, R10, and R7. It also fits APS-C Sony cameras such as the Sony a6700, a6300, a6400, and a6000. It fits all Fuji X-mount cameras and Leica L cameras. Tony tests the sharpness, contrast, handling, design, autofocus, and starburst. He specifically compares it to the Canon 10-18mm f/4.5-6.3 lens. The Sigma is superior in basically every way: it gathers more than twice the light and it's sharper. However, the Sigma lacks image stabilization.
