You have to choose your poison. You can go for a glassless adapter but you have give up on infinity focusing. If you want to keep it, there are adapters with a glass that will destroy any benefit from using an older, cheaper, higher-quality lens.
Then there's the third option: making the lens shorter. There are conversion kits out there. Personally I'm going to order one - yeah I'm the newfag considering an FD 55mm SSC f/1.2, going to work my ass off so hopefully I can get it while it's available and post some results
