I took the Sigma 150-600 mm Contemporary lens to Cape Henlopen in Delaware to try it out there. It's really a pretty nice lens for the price. I am still coming to grips with it. I haven't had many opportunities to really use it. It is quite heavy so I need to use a monopod or a tri-pod most of the time.
It was a really hot day so I didn't stay very long and the birds seemed to be hiding as well. Saw just a handful of egrets and this green heron. I should have gotten there earlier in the morning before it got so hot. Next time! The fall should be a good time to catch the migrations.
