Despite the loss of two stops, this is a useful bit of kit to get you out of trouble when you need a longer lens than the one you’ve got. However it’s important to check whether the lens you’re using is compatible, as zoom lenses which stick out a long way at the back may not be usable. For example, they’re fine on the 18-80mm and the 45-250mm Arri Aluras but not on the 15.5-45mm Alura.
