I purchased a macro tube (~$30) for my trusty Olympus OMD-EM10. Started playing around with the macro effect in the back yard. The macro effect is so strong, and it really has the power to transform a typical backyard into an extraordinary place.
The macro tube worked quite well. The depth of field was vanishingly small and I found it difficult to get enough of the flower in focus. Slight movements of my hand were enough to take the flower out of focus. This was not helped by the fact that auto-focus was not functional.
