Hi everyone,
Just first like to say how delighted I am to have found this forum having purchased a new 'Q' only last week.
Regarding fitting the hood, I too found the tightness and subsequent 'off-set' position a slight problem until I smeared the lens and hood threads with a smidgeon of oil (from behind my ears actually!)
I've used this lubrication technique before for various applications and have found it to be a useful standby!
I also note that when the hood is perfectly aligned on the front of the camera, a soft 'click' can be heard and the hood won't rotate further, serving to indicate that that it is seated correctly and symmetrically.
A nice touch I thought and a reassurance that it's simply not possible to over-tighten the hood.
