Just added to the color shading / vignetting page in my Sony NEX-7 review are results for for the Leica 28mm f/2.8 Elmarit-M ASPH and 50mm f/0.95 Noctilux-M ASPH, AND for the Sony 24mm f/1.8 Sonnar.
By showing color shading, one gains insight into potential performance issues on the Sony NEX-5N, Fuji X-Pro1, and similar ALLVIEW cameras.
Sensor design can vary greatly, and thus one cannot even assume that the NEX-5N will behave like the NEX-7. What can be said is that if a sensor interacts the way the NEX-7 does with one lens, then it will interact for the same reasons with other lenses.
