Here's one of the images I was able to capture at the St. Augustine Alligator Farm. This is a Snowy Egret. These smaller egrets were just starting to build their nests, so many were still looking for their soul mate. This guy (I assume he's a dude) is working hard at it. He's showing the other birds all he has to offer, for sure.
I shot this using my Sony A77ii and Tamron SP 150-600mm F/5-6.3 DI USD Lens. If you notice, this was shot at a shutter speed slower than I normally prefer. However, since the Sony A77ii has image stabilization built into the body, I was able to pull this off.
I recently did a presentation and I mentioned to them that this lens is the absolute best buy in photography right now. I truly believe that, too. The first thing I always get asked about the lens is "How sharp is it at 600mm?". It's fun to watch their eyes light up when I show them images taken at 600mm. They are always shocked at the sharpness. For $1069 retail, it's a tough deal to beat.
