How to solve the NEX7 lens dilemma?

Not relevant or anything but why bother getting the said "camera of the year" and not using it?

If I were in your shoes, I'd sell the OMD, and get the LA-EA2 and the 18-200.

It sounds like you want a single lens solution, so in my opinion (and echoed by others throughout the forum) the 18-200 is a very good solution as far as walk around.

If I'm mistaken and you aren't limiting yourself to a single lens, then a set of primes would be the way to go.

You might wanna expound on this "dilemma" of yours. From what I can gather, money isn't a problem, yet you say the adapter is expensive  o.o.....
