I had a similar question some time back. Here is the most helpful response i got. In my case, i havent filed it yet because i like the lens and it works fine with my manual focus cameras.

I had a Vivitar K-mount lens with a larger than needed flange. I just carefully cut off the excess metal with a small file. I used a Pentax lens to give me a guide for the final size of the flange, then marked the vivitar with pencil where I wanted to remove metal. I covered the glass with a post-it note (sticky stuff comes off easy, and protected the glass from the metal filings) and kept a vacuum handy to remove the filings as they accumulated. The final result was perfect, but I took it real slow and easy every step of the way. -- John Mustarde www.photolin.com - This message is from the Pentax-Discuss Mail List.
