Lens/Camera adapter issue with EOS 50D and Vivitar Series 1 600mm

[MichaelB4]

Excuse me if this question has been asked before. I was given a Vivitar Series 1 600mm #Catadioptric Telephoto lens, and the adapter that came with it won't work on my Canon#EOS 50D. I was able to remove the old adapter, and now I'm looking for the correct one to use between the lens and camera. Is the Canon T1 adapter the correct one to purchase? I know about the limitations of the lens, but I'm concerned about it.

Thanks to the community.

Yes, the solid model, and it came with all the filters. I'm interested in photographing birds with it.
