This article is, quite simply, false. DSLR cameras have much superior sensors to consumer end cameras, including smart phones. The sensor makes an enormous difference in the photo; much moreso than the lens. Heck, I would be a 5D Mk III for the ISO improvements alone, forget the lenses. Unless you're doing something special that requires (a) zoom or (b) wide angle, the kit lens will do you just fine.

This guy is either a gearophile elitist or he's making referral money on those "pancake" lenses and the others he is casually "recommending".
