Re: K/M/A f/4 100 mm macro vs FA-100 f/2.8

Hi!

My answer to similar question was to buy Tamron 90/2.5 SP lens in 
Adaptall 2 mount. It is fast and quite excellent optically. 


Is this a 1:2 macro?

It is 90/2.5 1:2 macro and with matching adaptor it is 180/5 1:1 macro. 
The latter being even more useful because of greater working distance 
from the subject - less intrusive!
