Those are some great shots. Really shows off what we can do now with this camera! Last week for a black and white available light at night class at my photography school I was shooting in monochrome at ISO 25,600 to get some nice, slight intentional grain etc. I was showing some of my shots to other students in another class yesterday and it really blows the mind. Even caused a girl to blurt out an expression of expletives!
Really great camera. Thanks for sharing! Please continue to do so.
