Is your 35mm 1.4's f stop easy to turn or hard to turn?

My first was too easy. It would move with the slightest handling of the camera. The second is stiff, and though the camera knows the setting, sometimes it stops between clicks. If it is close enough to 2.8, for example, the camera will show the 2.8

Personally I liked the easy one. Liked the easy clicks. Does it loosen in time?
