Close-up Filter Ring +1 +2 +4+10 in Sets for SLR / Digital Camera Camcorder 40.5MM
Close-filters, also known as close-up lenses or macro filters, attach to the front of a lens or lens adapter and extend the close-up range of a digital camera. Though not as superior as a macro lens, close-up filters are small and lightweight.
Close-up filters are much less expensive than a dedicated macro lenses too. While they can reduce image quality they also provide better magnification than the built-in macro mode found on many digital cameras.
