[QUOTE="BackdoorArts, post: 297886, member: 9240"] The answer is "It all depends". A lot depends on what macro lens you're talking about and what lens you're attaching the tubes to. Will it be more expensive? Almost always. But "Better" is a horrible word when comparing things like this. As for your specific question... You have a 50mm f/1.8g, which has a 1.48ft. minimum focus distance. Extension tubes effectively increase your magnification by reducing your minimum focal length. The 105mm has a 1ft minimum focus distance, so technically, you can get extension tubes to get you closer, but the magnification of the 105mm may make it appear larger/closer. The real question is, "How close do you want to get?" My personal opinion is that a macro lens will almost always be better suited for macro photography, but at a cost. If you're serious about getting up close, get a lens. Otherwise, tubes work great as long as the lens you attach them to is of good quality. There are lots of tutorials out there explaining the math behind how tubes work. As long as they allow your camera to communicate with your lens properly (and don't allow light leaks when stacked) they are a great solution in that they don't introduce anything between the optics and the sensor except space.
