On this weeks episode of "This Week In Photo", Frederick Van Johnson interviews Giulio Sciorio. You can find it here.
Giulio is a professional photographer who has sold all his big gear and now shoots exclusively with a micro 4/3 camera. He tells you all about small cameras at his blog, "Small Camera Big Picture".
If you're thinking about buying a smaller camera, you may want to check out his blog. I'm really liking my Lumix G5.
