too many 50's?

[Mark Erickson]

All, 

I'm not sure how it happened, but I have managed to accumulate an assortment 
of 50mm lenses.  My current collection includes the following:

 M42     F1.4 (SMC, I think)
 SMC-A   F2.0
 SMC-A   F2.8 macro
 SMC-FA  F1.7
 SMC-A   F1.2 

The M42 and SMC-A F2.0 lenses came with bodies that I inherited, but I 
purchased the others over a period of several years. 

So how many is too many?  Anyone else have a large assortment of lenses with 
the same focal length?
