With 35mm-full-frame cameras, you start getting telephoto depth-of-field effects at 100mm. Try focal lengths of 200mm and longer to get some very dramatic differences between subject and background.
You may know that APS-C cameras have a smaller sensor than 35mm and will then change how a given focal length performs for a particular composition. They make any focal length ...
