(...) The 800 series use the same sensors from Sony. What sort of problems do they pose? (...)
I don't know, Vivek.
My own personal experience is limited to an attempt with combination of some Leica M optics mounted on Micro Four Third cameras.
To my surprise that experiment didn't turn out very well despite the fact that the M4/3 sensor has an area of only about ~ 25 % of the format the M lenses and their image circles were designed for.
This made me suspect that optics with their optical formulas are designed for specific flange-to-sensor distances, and maybe also the other way round that sensor layers and their thicknesses are designed for specific optical formulas.
Otherwise I don't get it why an expensive full frame M lens could be such a disappointing performer on such a small sensor that only uses the very best centre of the image circle ?
I have just read so many times about problems with all these combinations that I for one prefer to just stick with native mount lenses and concentrate on content.
That's just me, and you probably shouldn't take too much notice of this preference of mine.
Whatever works well for you is of course fine.
With regards to Nikon I just hope that the F-mount will survive the transition to Electronic Viewfinder cameras if at some point the Nikon company decides to take that EVF route for its FX and DX format cameras.
In the hope that my lenses will stay native-mount lenses and not become obsolete.
In the hope that I don't have to start all over and buy new native mount lenses.
That's all there is to it.
I'm not so sure that the D800 series uses the same sensor as Sony.
I suspect that both of them are designed and optimized for each their lens mount respectively, simply due to the different flange-to-sensor distances ?
As I said I got the impression from the above mentioned presentation video that the A7R sensor needs offset micro-lenses whereas I have never heard or read that any of the D8xx series sensors use offset micro-lenses.
