Yesterday I was out at some yard sales and i bought a small group of camera related items. For my $10 I got a slave flash , a polarizing filter and a brand new, in the box, lens. I knew that the lens wouldn't fit my Canon 20D but the other two items were worth the money.
When I got home, I did some checking on the lens and apparently it's a well rated lens. It's a Vivitar 70-210mm f4.5-f5.6 Macro. It is one of the last all metal lenses made by Vivitar. I'm wondering if there is any kind of adapter that would allow me to use this lens on my 20D? It presently has Yashica/Contax mount.
