Nice. Which E-Mount lenses do you have for your NEX?
So far, I only bought my NEX with the 18-55mm kit lens. I figured it was the most useful/flexible combo for me for typical walkaround use - it doesn't have the telephoto of the 18-200, but is far more portable. The 16mm was interesting, but the prices were good with the 18-55, and the two lens kit just wasn't quite worth it for me as I truly wouldn't use the 16mm very often.
Most of the lens kit I've built up so far has been older lenses from two different mounts - Pentax and Konica. The Pentax mount I already had - I have a '77 Pentax ME Super and some lenses to use, so that adapter was easy...the Konica adapter was because it was one of the smaller adapters available in 35mm, and the lenses were held in high regard - but are available super-cheap.
Your reviews prompted me to make a change to my camera setup. While I loved my DSLR setup's capabilities, for me the whole setup was just too big (too big to bring on the motorcycle, too big to haul around the parks, etc). I found myself leaving the camera at home, more than I brought it with me. I wanted to downsize, but didn't want to totally give up what I had learned while shooting with a full size DSLR.
Understandable. For me, the NEX is a second body, as I couldn't live without a DSLR - too much wildlife and action shooting which needed the long lenses and fast focus abilities. But I do have those times that traveling with something smaller and lighter is just a nice release, and other times where I want a second body on me, but carrying two large DSLRs doesn't sound too enticing.
With that in mind, I put most of my kit up for sale and have a NEX-5 on the way. I love the option to shoot video with the same body (with pretty impressive results), but still have good control over my photos and the ability to shoot in RAW format. I ordered the kit with the 16mm & 18-55mm lenses and for now I plan on holding on to my Minolta beercan and get a converter for it.
Sounds like a decent plan. If you do get a Minolta/Sony A mount adapter, it is probably worth pitching in for the eMount one available through Sony - it's pricier than the cheap ring adapters, but maintains aperture control on Maxxum lenses, and even allows autofocus when paired with any of the A-mount SAM/SSM lenses. I didn't have any SAM/SSM lenses, so I didn't bother with that adapter myself...since I'm keeping the DSLR, it will still use all the Minolta/Sony glass.
I strongly advise getting the firmware 3 update. If you want to maintain manual control over the camera, it makes a world of difference - without it, it feels so restricted, like a P&S model - once you do the firmware, it feels like an advanced enthusiast tool - all the relevant camera controls can be placed at one-button access.
And eMount looks to have a good future - not only will Sony be releasing more eMount lenses in the near future, including some nice Zeiss primes...but Sigma, Tamron, Tokina, etc have all signed on to building eMount-spec lenses, so the future lens map looks pretty decent for the format. And aside from that, the miniscule registration distance means lots of fun with any 35mm or rangefinder lens ever made! I even think the little guy looks quite awesome in a modern-retro style when paired with a nice 35-year-old lens:
