Did a shoot this weekend, RC Drag races for Middle River Hobbies. I was a little worried on the focus speed with the tamron, however, it tracked and got these sub 2 second cars surprisingly well. Here are a few examples. This last one, happened so fast, that i didnt get that great of a pic of it, but i think it did satisfactorily. Shot with a D200 and a Tamron 70-200 f/2.8 CC Welcome.
