Interesting. But read test of this lens in Popular Photography: http://www.popphoto.com/article.asp?section_id=2&article_id=327 They rate 24-90 as 24.42-87.14 mm in reality. Who is right? Also, have you tried 24-90 at different focusing distances? Internal focusing AFAIK changes a bit focal length, so maybe here is the point? -- Best Regards Sylwek
