symptoms that you have LBA are the following:

1.> you need to have a lens that you dont really need nor intend of using.
2.> your set budget for one lens goes beyond what you normally planned due to the fact that you saw the opportunity to buy certain lenses that are a steal or bargain of a price that you believe does not come that often.
3.> your last set purchase is not really the last purchase. it just never ends.

there's a bar joke about this japanese samurai who collects swords..

Note from the OP. Another way to tell if you have LBA: Experienced photographers tell you the lenses you have are fine and all you hear is white noise. Thanks for all the advice and confirming that I really do need another lens.

True LBA is buying a 24mm Spiratone that you know is crap but you have to buy it anyway because your other 24mms say Pentax, Vivitar and Soligor, but don't say Spiratone.

Gregor I think you need at least 3 more lens !!!!! And a TC or 2.
