Dennis wants to take some close up photos of diamonds and gems using a point and shoot camera. Can he do that? He can't afford an expensive macro lens. Leo says that point and shoots do macro photography quite well. His first choice would be the Sony RX100 series. It has a 1" sensor, which will give him the best results.
Leo recommends going to DPReview.com for reviews of cameras. They also have a very good video out on Macro Photography.
