And it never will, as long as more photographers concentrate on actually using their kit - using it well - than worrying about spec sheets and what online "experts" tell us is supposely wrong with the gear.
Right now I don't see anyone worrying about specs. I see a lot of people worrying about actual sample images. Call me kooky.
Right, and no one really actually seems to see those sample images for what they really are: Demonstrations of CONSIDERABLE, VISIBLE improvement over their direct PREDECESSORS! You can complain about the 5D III all you want...all of the samples so far show that it offers a marked improvement
over the 5D II in terms of IQ: Far lower noise at high ISO, elimination of fixed pattern noise, reductions in banding noise (only very slight vertical banding visible in highly manipulated images dragging shadow data up by 4-6 stops), stunning color fidelity, excellent sharpness thanks to a less aggressive low-pass filter, etc. Thats nothing to say of the functional improvements, such as the 61pt AF system, 100% viewfinder, etc. A win for Canon!
The same exact thing goes for the D800 vs. its predecessor. Its also a huge improvement, despite offering three times as many pixels as the D700. The IQ is still stellar, low ISO DR is still stellar. On a normalized basis, the D800 outperforms the D700 in just about every way. A win for Nikon!
There is nothing to complain about here. The 5D III and the D800 serve different markets, different demographics. If you need uberpixels
, either jump ship and go Nikon (and incur the extreme cost of doing so to replace your entire kit), or just bid your time and see if Canon releases a 40mp+ competitor later in the year. If you don't need uberpixels, or really need high ISO/low light capabilities with low noise, then you really don't have a leg to stand on regarding the IQ of the 5D III. From a technical level, its a strong improvement over its predecessors. From the level of subjective observation...the photographs from the 5D III, at ANY ISO, are unbelievable and highly, highly competitive with images from other cameras on a realistic
basis (i.e. without manipulating shadow data by 6 stops to compare data at the bare extremes of what any camera is capable of, demonstrating whats possible given an excessively rare need in real-world situations.)
