Snow Leopard Cubs, Bronx Zoo
According to a nearby sign, the exhibit was to be closed for the day. Several visitors grumbled before moving on hastily. I was about to do the same, but I noticed something move behind the glass.
With the Canon 6D and 70-200mm lens at f2.8 I was able to photograph the curious cubs. They were born in May, making them just over 4 months old.
