Kenko
A close-up lens that allows macro photography simply by attaching it to the front of the lens.
The shutter speed does not slow down when attached, so close-up photography is possible while maintaining the lens's brightness.
Higher magnification photography is possible by stacking close-up lenses.
Multi-coating is applied to both sides of the lens to reduce reflections.
Minimum focusing distance: Approximately 25-50cm (No. 2 type)
