Last week i was photographig tulips when all of a sudden a yellow wagtail landed on a field of red tulips. That was a great oppertunity, but not an easy task when you are foccused on landscapes with a 5D and 24-105 lens. I tried to change to a 300/2.8 with 1.4 tc as fast as possible. This was the best i could make of it.
