the FE 85 1.8, seems to have made the Batis "obsolete" not in the sence that batis is bad... but not worth the premium. I have the GM 85, but if I was buying a lens today I would go for FE 85.
I would have probably bought the FE if it had been an option at the time even though I love the Batis. The FE is great value it seems. I was thinking of selling the Batis and picking up the FE to release some funds that I can put towards another lens but will have to weigh that one up as I will lose a bit with ebay and paypal fees
