Hello! can someone help me if this constellation works?

Olympus E-3
Zuiko 12-60
NN3
?

It would be very interesting because the NN3 is still light enough for traveling and even the price!
And the 12-60 is always "on board"

German seller told me I have to try it. In general the NN3 would be for fisheye only?
In future I will have an eye on the Zuiko Fisheye or Peleng, but th e 12-60 is my everydaylense. Great glass!

So, I hope for any response!
