Thom Hogan review of NEX-7

So you have a list of 14 lenses. With essentially none being the 'critical' key stone focal lengths with demanding apertures. I'm not defending Sony's roadmap as both Samsung and Fuji have taken a more thought out road but 90% of those lenses you're asking for will not sell well to the general public. And those, especially the wider focal lengths, are already available in the legacy market where auto focus isn't critical in any case.

Bottom line becomes if you want a mature system you have the Nikon, Canon, Sony SAL, and m4/3, Pentax, etc. systems to buy. You're buying into a really new system and the idea that you'd expect Sony to R&D and release that many premium (very very few of those lenses will go for less than the body itself, if any) lenses... seriously go legacy or just forget the NEX system all together as you will not have your wish list in the next 5+ years.

Sony needs to get items that will sell to the consumer public.  The professionals can't deal with the current issues with AF and speed on a consistent basis.  Not to mention the cost of replacing glass.  The NEX system is currently a consumer system with the potential to develop into a lighter more professional system.  But if you're expecting those types of focal lengths with that kind of speed go legacy or be disappointed.
