Whipsnade zoo

Had a fabulous but very hot day today at Whipsnade zoo.  We took our son there for his birthday.  My birthday was 2 weeks ago and I finally collected my new lens this morning from T4 Cameras in Witney.  So where best to try it out than at a wildlife park.  I'm very pleased with it (it's a Canon 100-400mm).  Thankfully tomorrow is going to be cooler.  I don't cope well in the heat !
