Joe, I had been considering selling my XE2 but lately have changed my mind because of the 27.
As soon as there's a Fuji sale or I see a good used price I'm getting one to permanently mount on the E2.
Yes, it's a bit slow but from what I've read it performs quite well wide open.
Fortunately, too, I like a 40mm FL.
also, in the Smaller and Slower Department: here's a vote for an
18mm f2.8 pancake.
Bunch of Nikon and Fuji X digital stuff
