I have long been meaning to upgrade my telephoto zoom lens so that I can get better reach when photographing surfers and wildlife, so when the Sigma 100-400mm X-mount came out I nabbed one.
I haven’t used a lens of this length before and it has been an interesting experience. Due to reasons I have not been able to get out much but managed a couple of excursions to Chew Valley Lake and Tyntesfield to try the lens out. Lots to learn but it was enjoyable getting to grip with new focal lengths and new techniques. Photos below.
