Close up filters

A close-up filter is one of the simpler ways to adapt your lens for increased magnification. It’s essentially a piece of glass which simply screws onto the front of the lens. This adds an extra layer of magnification, although offering more potential for light to be lost on the way to the sensor, as thicker glass is added to produce the desired effect. The attachment process is far more straightforward than with lens reversal and extension tubes, and simpler for beginners, but the image quality isn’t quite the same.
