Minimum Focusing and Minimum Working Distances
Minimum Working Distance
The distance between the subject and the front end of the lens is referred to as the working distance. A larger working distance will make lighting and composition easier.
When photographers ask the question, “How close can you get,” they are usually referring to the minimum working distance from the lens to the subject.
Minimum Focusing Distance
In photography, each lens has a minimum focusing distance, which is the closest distance from which it can capture (focus) a subject accurately.
If you attempt to get closer to the subject than this specified distance, the subject won't be in proper focus.
This defined Minimum Focusing Distance, measured from the film or sensor (not the front of the lens) to the in-focus plane of the subject, is attained when the lens is at its closest focus distance.
This distance varies depending on the specific lens.
This critical specification is commonly featured in camera and lens brochures and proves especially valuable for tasks such as extreme macro and micro photography.
