If you need even greater macro magnification than the Canon Extension Tube EF 12 II offers, there’s always its 25mm sibling. It shares all the same features and is also fully compatible with the vast majority of Canon EF and EF-S optics. However, with greater magnification also comes a bigger price tag.
The in-built Ultra-Sonic Motor (USM) drives fast and quiet Auto Focus with optional full manual override. Reduce ghosting and flare with Super Spectra coatings. A circular 8-bladed aperture diaphragm gives out-of-focus regions a softer, more uniform feel. Weighing in at just 290 g and measuring at 73.8 x 50.5 mm.

Free shipping on all orders over £30!I researched that extension tubes are the best option to get started in terms of image quality. I can't decide whether to get the EF 12mm II or the EF 25mm II extension tube. The camera that I have is a Canon Rebel T6i. Also, I have 3 lenses which are the 18-55 IS STM, 50mm f/1.8 STM & 55-250 IS STM.
