Goodbye Nikon

Welcome to the world of Sony!  You will love their unique cameras and the 2 you have are their best along with the A99!  I have all three.

The favorite lenses for my NEX are:

50mm f/1.8 DT Alpha A-Mount Prime Lens (great inexpensive lens, cannot go wrong) along with the LA-EA2 adapter

For the widest end: Zeiss 18mm f/4 Distagon T* ZM (manual focus, easy with focus peaking, needs an adapter)

Various Minolta Maxxum lenses w/the LA-EA2 adapter are excellent.  I love my 135 2.8 and my 50mm 1.4, my 70-210 f4 beercan and 75-300 f4.5-5.6.

Can't go wrong with a 28-75, I have the Tamron in a Sony mount.

One size fits all, I have the E-mount 18-200mm f/3.5-6.3 which isn't bad, but I like the others better.

I don't care for either kit lens (pancake or 18-55).
