We were out driving on the Serengeti when our driver guide spotted lions in the grass. We stopped to look at them and then saw them climbing the tree and started shooting!
We knew lions climbed trees in Manyara, but had not even seen a lion when we there, let alone ones climbing trees. So to see them in the Serengeti was something special.
I had only taken up photography after going on safari to Kenya in 2010 but this time I had a new DSLR and hired a zoom lens – a Canon EF 100-400mm f/4.5-5.6 L IS USM – just for the trip, and that was what I was using on the day.
