Got to test out a couple of Sigma lenses this last few days. A Sigma AF 20mm f1.4 DG HSM Art and a Sigma AF 100-400mm f5-6.3 DG OS HSM C.

Here are two photos comparing the zoom range of the Sigma 100-400mm lens. One of the left is at 100mm and the one on the right is at 400mm.

And that after I heard a lot of helicopters flying close by so took the chance to take the lens out and take some photos of them. It wasn’t until after I took some photos of them that I read in the news that there was a bushfire nearby – which explains why they were there.
