Re: [OM] Tamron 90 f2.5

[NSURIT]

Sounds good to me.  Do you know approximately what is the length of the 
Tamron tube?  Same logic works on the Tamron 2X converters.  You pointed out 
50mm f3.5. I'm assuming you are not looking.  I have one that is a black nose 
with a couple of cracks in the rubber on the focusing ring and a small amount 
of oil on the aperture blades (which is not affecting their proper operation) 
That I would like to sell.   BB
