This extension tube is designed for macro photography and is made of high-quality ABS and copper contacts. It perfectly matches single-lens reflex cameras and supports automatic focus. It allows the lens to be mounted at a closer distance for higher magnification. The set includes two rings of different lengths that can be used individually or combined. Since magnification changes according to the length of the extension, you can achieve close-up shots of small subjects. It enables use of all camera modes, though exposure compensation may be required.Extension tubes allow a lens to focus closer than its normal minimum focusing distance. Getting closer has the effect of magnifying your subject while maintaining optical quality. When using the extension tubes, you can use the 10mm or 16mm tube separately, or combine them: 10mm + 16mm = 26mm. The effective extension length equals the total length of the tube used.Features:1.
