I believe the technical name is Nikon Acquisition Syndrome. It's an illness

so fantastic and so horrible at the same time, and nice and expensive to boot!!
Not sure if there is an exact definition for it...but this is how I define it:

The constant presence of an empty wallet in my purse since purchasing my first dslr. Some people may also define it with a look rather than words...you know, that look your spouse gives you when you walk in the door with another box from
Amazon, Adorama or B&H??? Yeah--that one.
