What Does MFD Stand for in Photography and What Does It Mean?

MFD stands for ‘Minimum Focusing Distance’. It is the minimum distance between a camera sensor or film, and image subject, at which a lens is able to focus on the image subject. MFD can be measured in meters or inches and is often marked on a lenses barrel. Knowledge of the MFD of a lens allows a photographer to make the right creative choices when positioning himself in relation to close subjects ensuring the required image sharpness is achieved. In situations where capturing the image you want requires the use of a specific subject distance, knowing the MFD of your lenses can help you make sure you choose the correct lens to ensure you can achieve pin sharp focus on your subject.
