If you upgrade to a Canon full frame camera any Canon "EF" lenses will be compatible. However, you can not use Canon EF-S lenses with a Canon full frame camera. I know that the Canon EF 50mm f/1.8 will work, but I'm not familiar with the 85mm f/1.8 lenses. If it's an EF series lenses it will work on a Canon full frame. Hope this helps.
I would recommend:
Sorry, there was a problem. Please try again later.Only Canon EF lenses will work with a full-frame camera such as the Canon 6D. Your 50mm f/1.8 will not be compatible with one, but your 85mm f/1.8 will.
