Hi, I bought Tamron manual SP 90/2.8 macro for my PZ-1 but adapatall has not reach me so far:( I have read some reviews of the lens and in German tests it performed super. And I have found Popular/Practical ( I do not remember which it was)Photography test of some macro lenses and Tamron got 9/10 and only canon USM beat it.It performed better than Nikkor and Pentax FA. So it must be very good beast! Alek
