This extension tube is designed for macro photography and is made of high-quality ABS material with 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 varies with the length of the extension, you can achieve close-up shots of small subjects. It enables the 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, effectively magnifying the subject while maintaining optical quality. The tubes can be used individually (10mm or 16mm) or combined (10mm + 16mm = 26mm), with the total length equaling the tube length.Features: 1.
