Adapting to what camera? Make sure that adapter is high quality, with electronic connectors to preserve auto-aperture and auto-focus.
Adapters may effect focus at infinity, but do not negatively effect macro work.
The camera is a Canon 450 D or xsi depending on what country you are in. It is listed on Craigs list and I called the gentleman about it and he is 86 and said he used to be pro, but sold most of his stuff about a year ago but missed this lens. Thanks for the reply.
