42mm to Wide 48mm T-Ring Conversion Kit - Converts most 42mm T-Rings to 48mm

T-Ring for Canon EOS SLR/DSLR Cameras
EF/EF-S Mount

Converts most common T-Rings from 42mm to 48mm (0.75)

Standard 42mm T-Rings will vignette badly when used with most newer Full Frame cameras. Wider T-Rings for some newer camera models can be difficult to find in the larger 48mm format. Finding a great fit can be even harder. If you have a good fitting ring but need to connect to larger 48mm accessories this kit is the solution. 

This set includes a new 48mm Inner Ring with 48mm (0.75) threading. It also includes 3 new quality replacement set screws as well as a hex wrench. The screws and wrench fit 85% of T-Rings and are included because the original screws tend to be of very poor quality. Some T-Rings use a smaller screw, these are not included as they tend to be of good quality from the factory.
