The rear lens focuses and magnifies the beam onto the larger 5.5” front Fresnel lens, maximizing light utilization. Our dual lens optical design makes the Fresnel 2X twice as powerful as the original Aputure Fresnel, and makes the 120d II almost 10 times brighter than with the reflector.

Circular polarizers, also called CPL filters, are a staple in all photographer’s camera bags. Landscape photographers in particular often use circular polarizer filters. They can also be useful for taking pictures of cars, street scenes, and objects in sunny conditions.

A circular polarizing filter is similar to your polarized sunglasses. Wearing your sunglasses reduces glare and makes colors more saturated. The filter will help you to achieve similar results by filtering out light that causes distractions.
