Chasing Rainbows with the Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens

When a unique weather pattern arrived with numerous little rain storms showing on the radar, it seemed like a good time to go trail running with the lightweight Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens. After photographing some distant storms from a high vantage point, I took a direct hit from one of them. But, that was good news. Rain storms make rainbows and this one delivered superbly.
 
Also delivering superbly was the Sigma 100-400. While a telephoto zoom may not seem like a first choice for landscape photography, this focal length range is excellent for that purpose (and many others of course). And, using a telephoto lens for rainbow photography is often a good idea.
 
It was a good night for a run with the camera. In addition to some intense rainbow images, I brought home a large number of nice dramatic sky images including at sunset – and got some exercise.
