With the storm season coming to an end its time I changed direction in my photography. About this time of year we get thousands of birds mirgrating through north central Texas and these birds become the new focus. Now that my Sigma 500mm f/4.5 lens has been repaired I am ready for this new season. Yesterday, I took the lens out on a field test. It seems to be working just fine. I will plan to make a trip to Hackberry Flatts on Labor Day weekend.
