I designed this in order to use my Canon EF 300mm f/4 L IS Lens with Zwo Asi Cameras.
Since the Zwos have relatively small pixels, i wanted to step down the lens in order to avoid fringing and other possible artifacts reveiled by the small pixel pitch if shot wide open.
Usage:
The lens it was made for has a sunhood. Just extend the hood and the ring should fall right into the hood.
Please let me know any tips for improvement.
Other step-down rings will be coming soon.
