Yesterday I posted about the Rokinon 500mm mirror lens I got, one of the accessories it came with is a 2x doubler or magnifier which boosts the lens to 1000mm. My initial tests of the lens were done in my backyard and 1000mm was a bit much… basically, nothing was far enough away. So, I went out to Dunmore Reservoir #1 and gave it a test. Here are a few of the shots I took of a family of geese.
