I don't really know how close I will be able to get. I've never done this before. And I don't want to be the 'crazy' camera uncle taking every photo 2-6 inches away like I do of leaves, flowers, and bugs.
I'm also not sure how low light this will be. I'm sure that there will be times when the wide open aperture will be needed. But, I'm not sure how much they move, if I would have a tripod, live view, or remote shutter (landscape photography is much easier
) I also have a 16-35mm f/2.8, but I will have to test that out on some baby toys first.
Another of my favorite shots is the baby's tiny hand wrapped around the finger of the father.
That is a good example, but I don't know if you would use an extension tube for that picture or not.
I'll look up some sample pictures tonight.
