Perfect Backfocus

This adapter provides perfect back focus spacing for attaching my ASI533mm with its 6.5mm sensor inset with the EFW mini to my Canon 200mm f/2.8 EF lens with its 44mm back focus.

Worked Perfectly

With my old setup I could not achieve focus with my ZWO ASI1600mm camera and filter wheel connected to a 135mm Rokinon Cine lens. This adapter is precise enough that I installed it and it just worked! Thanks to everyone at All-Star for keeping these in stock, and sending it out fast.
