They won last night.
Their record is now 5-1.
First image is ISO 900, the subsequent three are at ISO 10,000 (yes, ten thousand). This was dictated by the rapid loss of light after the sun set, and also the f/6.3 max aperture of the Sigma on the telephoto end. However, the Sigma is a light zoom at a bargain price, and provides a very nice rendering, so the need for high ISO is a trade-off I can live with.
