Customer Review

The rings work perfectly and we can achieve impressive macro pictures, especially when using multiple rings simultaneously.

As against the development must be done manually and not always easy to obtain. The depth of field also becomes very low, so that you get easily blur.

A compatibility problem with a lens (F1.8 Canon EF50) it is difficult to remove once mounted on the rings. No worries however with other Canon lenses.
