Hi, last week I purchased a Nikkor 70-200mm f/2.8 lens from a highstreet store while in the big smoke. During the weekend I noticed that when it is mounted there is a bit of 'play' in the mount such that it moves a smidge when hand held. Feels like the points would be grinding if you move the lens, though that is probably an exaggeration and more the brain leaping ahead - certainly not as solid as the nifty fifty (my other lens) but perhaps the weight of the 70-200 plays a role.

I've come from a film background and not experienced this with my Pentax setups so a bit stumped.

Does this sound like a flaw or is it normal. Comments appreciated.
