All relative and subjective. You define your own "normal;" if it makes you uncomfortable, return it or have it fixed--if you can afford it. My own Nikkors span a wide range, from a relatively loose 35/2 O.C to practically fixed-focus 55/2.8 and 105/1.8. Nikon Canada quoted $174.95 to re-grease the 105--suddenly, I wasn't that uncomfortable with the stiffness, why, I was quite happy to leave it as it was!
