One of my flickr contacts (and also a mu-43 forum member) posted a fantastic explanation of his low budget photomacrography set-up. He's a very friendly and helpful chap and has a great sense of humor. He also takes some breath-taking macro photos. Take a look here ....... A low budget rig for focus stacking | Flickr - Photo Sharing! And he's very generous with his time and knowledge, feel free to ask any questions you have. He's adding the questions and answers to the flickr post so there's a great knowledge base he's building. I'm proud to know Craig.Taylor (or DrLazer as he's known here). I'm the guy who sold him that sweet G10 ......... if anyone thinks they need the latest, most expensive camera to get incredible shots, just check out that link.
