Product Description

Offering an exceptionally practical way to dive into high-magnification close-up photography, The ProMaster Spectrum 7 Extension Tube Set (12mm, 20mm, 36mm) for Canon EF/EF-S is a vital tool for macro enthusiasts, nature documentarians, and texture photographers. This three-ring kit delivers ample flexibility by providing individual, stackable segments that physically alter your lens's minimum focusing distance. A massive upgrade in macro capabilities without forcing you to purchase a specialized macro lens, these tubes create impressive reproduction ratios by safely shifting your optics further away from the camera's image sensor. The internal electronic pass-through design automatically mirrors data communication between the camera body and the attached optic to retain critical exposure data. This electronic harmony lets you keep pace with fast-changing natural lighting, maintaining full control over your camera's automatic metering and aperture selection. This versatile kit offers an accessible entry into specialized extreme close-up imagery, working beautifully as a standard everyday companion for native Canon EF and EF-S mount systems.
