Century Optics +4 Achromatic Diopter Close Up Lens for 58mm -
For maximum magnification and image clarity, these Macro Zoom Attachments give camcorders with small front diameter non-interchangeable lenses more close-up range, while preserving zoom capabilities. Available in +1.0, +2.0, +4.0, and +7.0 magnifications, Digital Series Achromatic Diopters are essential whenever you need to focus tightly on a small object in tabletop, miniature, and flat field videography. Integral 58mm threads make it easy to connect the diopters to the front of your small diameter video zoom. Two or more diopters can be stacked on the front of the lens for even more magnification. Step-up rings are available to adapt the Macro Zoom Attachments to lens fronts smaller than 58mm.
