Best MF vs Best 35mm
IQ180 vs D800.
IQ 180 wins without a shadow of doubt. (for what it is)
I've condensed those several pages to that.
Just to demonstrate that that statement is not actually true, here are some photos (taken from this link: http://forum.getdpi.com/forum/nikon/36838-someone-had-do.html) that compare the D800 to the IQ180. The D800 images have been downscaled 2x, the IQ180 images have been downscaled 3x. If what RL is saying is correct, the IQ180 photos should be winning hands down, no questions asked, stomping ALL OVER the D800. The extra downscaling factor should be giving it a FURTHER edge.
Now, for the facts. First image is D800, second image is IQ180 (As they are in the linked article). These are lifted a MERE 1.5 STOPS (EVERY camera on Earth can currently handle a 1.5 stop lift...so we aren't even remotely close to the realm of "only Exmor can do that" territory! )
MIDWAY BETWEEN CENTER & EDGE:
v--- sharp, clear, NOISELESS!! D800
^-- mostly sharp, noisy in the shadows! IQ180
v-- sharp, clear, NOISELESS!! D800
^-- not sharp, NOISY!!!!!!!!!! IQ180
Hmm...well, hell has obviously frozen over, the planets have stopped their rotation around the sun, the galaxy has certainly stopped spinning....because, the D800 appears to be...winning....HMM!
