Focusing distance

In the macro photography world the term ‘minimum focusing distance’ is thrown around quite a lot by the experts, and for good reason. It’s the closest that your lens can get to a subject to accurately focus, measured from the front element of the lens, and the closer you can get to your subject, the bigger it will appear in the frame. Generally speaking, the smaller the minimum focusing distance, the better chance you have of achieving frame-filling shots of small subjects.
