Sony a900, end every single one of these pics was taken with a Zeiss 24-70mm f/2.8. I also have a cheapo 10x macro effect filter I used for the close ups.
I don't even own a flash.. I need to remedy that, times two. I also need the Sony G-Series 70-400mm f/4-5.6 lens to add to my kit, but of course it only costs $1600.
..and a decent tripod
