Q: 1. Will this be compatible with a Sigma 50mm lens on a canon t6?

A: If the Sigma is compatible with Canon's EF or EFS mount, they should work. Just remember, that the range of focus is severely limited or tight, leading many first time users to think that they can't focus their camera using them. They can, but it takes about 3 minutes of practice.
