Experimenting with my new 50-500 to get an idea of what I could do with it hand held from the deck of my house. This is one of our 4 footed family looking up as I whistled to get his attention... Shot at 500mm

PS: This was also taken with my K-01 Camera which is a smaller Mirror-less DSLR like camera that Pentax made that still allows you to use full size lenses.... It looks completely absurd paired with my BigmaSigma but since the lens uses HSM it worked really well and I'm quite pleased.
