Selling one SMC A 1:4 70-210mm Macro F4.0 Constant Aperture

[Joaquim Carvalho]

I like this lens very very much but I guess I don't need three. Ebay 
auction #7521036745
In excelent condition but when it is put vertically the focus/zoom ring 
will slowly go up/down.
(the three of them are like this, as someone said on this list, it's on 
the nature of this zoom)
