Used Canon Extension Tube EF12 II

I’ve been using this extension tube on my 50mm lens, and the extra 12mm of spacing lets me fill the frame with even tiny details like flower stamens. The build feels solid and the electronic contacts work perfectly, so no loss of autofocus. Exactly what I needed for better macro shots.

Finally getting sharp close-ups of a coin's micro-texture without buying a dedicated macro lens. The metal build feels solid and locks tight with no light leaks during use.

I've been using this extension tube for close-up shots of flowers, and the build quality feels solid despite being pre-owned. It snapped onto my lens smoothly with no looseness, which was my main concern. Just wish the price was a little lower for a used item in this condition.
