This is the reduced focus and enhanced version of the Fringer EF-FX series intelligent adapter ring product, which can transfer EF mount lenses to Fuji X cameras while maintaining the optical performance of full frame lenses as much as possible. It adopts a brand new design of 2 sets of 5-piece optical lenses, which is different from some similar products on the market. This new design prioritizes image quality when matched with high-quality full frame lenses. In order to achieve this goal, we even sacrificed a little zoom magnification to 0.74x. The new product has autofocus performance and compatibility similar to the EF-FX Pro III.

Using this adapter will result in a shortened equivalent focal length and an increased aperture, for example, an EF24-70mm F/2.8 lens will become approximately 17-51mm F/2.0.
