[QUOTE="Dihusky, post: 455922, member: 10304"] It's all about capturing small stuff. There are basically three options for getting your camera to naturally capture small stuff, these are: 1. Dedicated Macro lenses; This is the most expensive option and with many of the modern lenses you can go very small indeed. 2. Extension tubes; This is a really good, economic option as they often come in sets of two or three and you can stack them together to capture smaller items. One big advantage is they are a simple tube internally, no lenses to get in the way, so you retain the original optical qualities of the lens you are using. If you have a macro lens these can be used to take you into the 'Micro' world. 3. Macro filters; These add to the front of your lens and unless you buy a very high quality one, can have a significant influence on the original optics of the lens they are attached to. They come in filter thread sizes and magnification factors so are not optically matched to your specific lens. Companies like Canon do have them but they tend to be optically matched for the longer focal length lenses, the 500D close-up Filter is for lenses 70-300mm for example. Personally I would go for Extension tubes if I didn't have a dedicated macro lens. [/QUOTE]
