It is really not the focal length, but the construction of the lens. Specifically, the ultra-cheap 50 mm 1:1.8 with its 5-blade aperture. Step up to the $350 50 mm 1:1.4, and things begin to look a lot better. Go up to a $500 Sigma 50 mm 1:1.4, which has a rounded 9-blade aperture, and it gets even better. [...] And going up to $1500 EF 50 mm 1:1.2 L will give an even smoother result. [...] But, while a more expensive lens will render the out-of-focus areas smoother ...

Oh please! Don't try to suggest all this bunkum to a beginner photographer. He might start thinking it was true ...

Okay—this much is true indeed, for a change.
