I bought an 18-270mm lens at a great price second hand but when I received it I found that there is a noticeable 'ramp' in the ease of turning the zoom ring when zooming in and out. It's sort of easy to turn at the wide end and easy to turn at the tele end but in between there's a really noticeable resistance.
I'm wondering if this is normal with bigger heavier lenses or whether it's a fault in the lens. If so, am I able to loosen it up a bit with some sort of lubricant or similar? Or is this a no-no??

It's more or less noticeable depending on which way you're shooting, i.e. if the lens is oriented downwards it naturally wants to 'creep' out due to gravity on the heavy glass elements (I guess!) but as long as it's not 'defective' I'm happy to apply some force! Within reason....
