This Close-up lens diopter offers an incredible way to capture the tiny world around us on a super-detailed level. It can be easily transported in your camera bag, backpack, handbag, or even in your pocket. You can venture out on an expedition with only a single lens, come across a tiny photographic detail out in the wild, reach into your pocket, screw the lens on, and get up close and personal with your subject. Remove the filter and press on! Exclusively developed for DSLR contemporary lenses, it offers a maximum magnification ratio of 1:10. It enables photographers to take a close-up picture of subjects such as jewelry, flowers, & insects. Made of double optical corrective glass with an apochromatic design and features a multilayer Nano coating. This enables advanced resolution and natural colors, with almost no purple or green fringing. It has no vignetting at 24mm on an APS-C sensor camera and 35mm on a full-frame sensor camera. The minimum focusing distance of this lens is 2.5 centimeters, its maximum magnification ratio is 1:15 and the working distance is 1.4 centimeters, which is similar to an extreme macro lens. It makes the rendering very constant across the wide-angle range and it enables higher performance in macro photography at 1:10. Even when this close-up lens is attached, the image taken at maximum magnification ratio, at 500mm, infinity, shows very little difference in MTF. Each surface of this lens is constructed from optical glass which includes three layers of anti-reflection coatings that offer improved clarity as well as more effective prevention of internal ghosting and reflections. This close-up diopter provides approximately 97% average light transmission and features an aluminum-alloy filter ring for durability while remaining lightweight. This item includes Lens, Filter pouch, 2 year warranty card. This Close-up lens diopter offers an incredible way to capture the tiny world around us on a super-detailed level.
