Hi Jono,
That's a wonderful image. I have the NEX-5N, should get the viewfinder by month's end, and hopefully the NEX-7 in April or May. I love my M9 as well as my Nikon D3, D300. The NEX-5N is beginning to grow on me.
This seems to be my usage pattern.
* I prefer to use the spectacular Leica M lenses from 16-135 mm on the M9.
* Older Leitz lens heads, with appropriate short focus mounts, as well as Telyts-V from 65-560 mm I prefer on my Nikons or with a Visoflex III on the M9. Also, the Leitz Bellows II is extremely useful in combination with these systems for macros.
* Finally, the NEX camera(s) permit me to use fabulous Leica R lenses with simple adapters without having to leitax them, as would be necessary for use with the Nikon cameras. Especially the NEX-7 should be very useful, once I have it, with my longer Leitz, Leica, or Nikon lenses. Of course, with appropriate adapters all my lenses can be used on the NEX cameras, particularly useful for lens comparisons. I even got the ZEISS 24/1.8 ZA, but it is no match for the Leica 35/1.4 Summilux-M ASPH on the NEX-5N. My thought was to have at least one autofocus lens for the NEXs.
I wouldn't want to give up any of these systems as they have their particular uses.
The Fuji X-Pro1 seems very interesting with regards to its sensor and perhaps its user interface. We'll see when it finally gets into customers' hands.
Of course, I hope (against hope?) that Leica will be imaginative with their M10 and MILC cameras if and when they finally will be announced and actually are available.
Regards, K-H.
