Hi guys,
need a lil help here,
i just wanna ask, why does my pictures towards the right edge tends to be blurry?
i notice it occuring several times over several photos i took in the past 3 months...
is it because of my lens (its bout 2 years old, and it has taken several bumps before accidentally)
or is it because of my settings/object movement?

i'm currently using a d7000 with 18-200mm lens...

here's a few photo samples:









thanks for ur replies
