The other two most common Sony choices, are the 18-200mm and the Sony-Zeiss 24mm, but the zoom is fairly big and not so much better than the default 18-55, and the Zeiss is quite expensive and not readily available as of today.
In general, there's aren't many choices on the market for E-mount lenses. It's possible to use Sony Alpha with a Sony adapter, which is also very expensive on itself. This will likely change in the future, but we want to get the best of our sensor right now, won't we ?
A very versatile cameraThe good news is, there are already many 3rd party lens adapters and, with these, it's possible to use almost any lens from any manufacturer, from the mighty german like Leica, Zeiss, Voitglander, to Canon, Nikon, and many others.
I'll specifically cover using Canon lenses on this blog: having used Canon cameras since the 70's, I have access to many optics, both in the old FD standard, and of course several EF (Eos) too.
A very quick test, just to get us startedWe'll enter into details with next posts but, for the time being, let's start with a very quick test that should make it clear why it still makes sense to use 30+ years old optics with a brand new camera such as the Nex-7. Here's a quick comparison of the default Sony 18-55mm, against a 1973 Canon FD 50mm 1:1.4

The weather wasn't very good on this shot, strong cloud cover and not much light, and It's not easy to appreciate the differences on a web page but, let's have a look at a 1:1 close-up:

This was by no means a serious test, just a quick one to get us started. More will follow.
