MTF only indicate a small part of the performance of a lens, you better buy
the Tokina 90/2.5 it has the highest MTF number. Zuiko 90/2 has very good
color saturation and tone rendering than the Tokina I once own. Have not try
the Tamron but third party lens usually has not very accurate color
reproduction. On the other hand F2 vs 2.5 already worth 50-100 0ncrease in
price. Just like 28/2 vs 28/2.8, 24/2.8 vs 24/2... etc.
BTW, I think Leica has similar MTF number too, why people pay that much?
