I shoot mostly macros. Most often I use the 50mm f/2. After that the 50mm and the ex25 extension tube get the most use. The 50mm f/2, 35mm and the 70-300 are the ONLY zuiko digital lenses that can shoot true macros. None of the other lenses even come close in terms of magnification.

I think this one was the 50mm and the ex25 tube.



For close-up work, or maybe better called "almost macro," the 12-60, 50 f/2 or the 50-200 are about equal. The 50mm is the sharpest and offers the highest magnification. The 12-60 is the most versatile. The 50-200 gives me plenty of wiggle room when I'm working with dangerous stuff like pit vipers. The 50-200 with the ex25 tube gives me a lot of working distance and also decent magnification. It also has the added benefit of a fast depth-of-field transition, so it is very easy to get creamy out-of-focus backgrounds.

In short, your lens choice depends on the situation. You can't go wrong with any ZD lens.

Here's one from the 50-200 with the ex25 extension tube.
