How is it a cop out? If you think a 16x24 image will look better coming from a 22mp sensor than a 36mp sensor because there is a slightly smaller amount of noise, you can try and do that, but I honestly don't think that's likely to be the case. If you think a high ISO 16x24 image won't look as good from a 36mp as a 12x18 image from an 22mp sensor, that becomes a more subjective judgement. But I can tell you that an image printed from the 36mp sensor will never look worse than an image from the 22mp sensor if both are printed at the same size.
So I guess I'm not really sure what the issue is If you want to print big, you will always be better off with more megapixels, and in a worst case scenario of extremely high ISO you will never be worse off than you would be if you had a lower megapixel sensor.
Sorry you seem confused, I'm not the one arguing that you should resample the Sony or that the 5D III image will look better at the same print size. I'm saying the opposite.

I guess I am confused. No one that I recall said the image quality of a 5DIII would look better at the same print size.
The point is the higher megapixel sensor gives you the choice of either printing larger or downsampling to reduce noise if necessary, and so in either case the quality of your print will be as good or better from the higher megapixel sensor. You called that a cop out, so I guess I don't understand why?

Not sure what fantasy world this statement came from.
Lets see Canon super teles all weigh 30-40% less than the Nikons..do Sony even make big teles?
The 1Dx wipes the floor with all of them
Unlike the guys here who believe everything in camera performance revolves around DR some other photographers think that Auto focus,FPS and hi ISO and DR and here we go the big word COMBINED give you the best PACKAGE.
With the D4's AF issues,the clearly superior AF of the X combined with better hi ISO and wait for it better hi iso DR plus the best lenses ever designed im just wondering which part of the equation other than low iso DR you are referring to that will flood the sports scene with "black lenses"
Canon has a massive lead in sports tech photography that is going to take Nikon a huge huge investment to get close.
Low iso DR for something like a 1Dx doesn't even come into consideration. ...Show more →
so many myths you are spreading
1dx can maybe be used to wipe the floor with

Sure Canon needs to step up the game for landscape and studio photographers with DR and more MPs. But your sporting event comment is totally off base.
Canon produces the best AF system now in any system (1DX and 5D3), Canon's super telephotos from the 300 2.8 up to the 600 f/4 and the 200-400 with 1.4TC are a long ways ahead of Nikon's current offerings for both IQ and weight. No one shooting sports is ever shooting at ISOs that even take advantage of the DR offered in the D800 type of sensor. Canon dominates the sports market, if it wasn't for the 1D3 debacle, I don't think you would even see any Nikon lenses at sporting events these days. And Sony for sports?? Come on, they aren't even in the picture....Show more →
1.more myths and no facts , show me one test there canon AF is better than Nikon D4 AF. A test in which all parameters are reviewed .
2. Hasselblads MTF lab (real MTF test) shows that 300, 400,500,600 from both Nikon and Canon have similar measured values.I have spoken with the test manager, the lenses are equivalent
3. Depending on where you are Nikon have here in Europe more black lenses at some sport events than you can see Canon whites

?? What are you talking about. The comment about matching Sony and Nikon and relating that to market share in sport photogs was 100% off base. Canon makes amazing gear for sport shooters. Nikon makes some great gear now, they were definitely behind 5yrs ago.

I tested all necessary operation for using the A7r on a tripod for landscape shooting, not convenient but still good enough, I'm ready for this weekend test shot
I understood this mechanism but when I bought this 36MP sensor I expect it can be used all 36MP resolution with good PQ and low noise like the 18MP sensor, otherwise it is just a technology "trade off" instead of "improvement".
The 2 stops DR on the scientific test is always true but so far from my actual test shots compare to my 1Dx I still can't find any significant benefit gain from it.

well you see it in a contrasty motiv, a motiv with large DR,where you can expose after the high lights to cover full color reproduction in highlights and then go down in levels where 1dx shows noise and banding compare to d800, here you find the 2 extra stops of DR
Regarding bashing canon as some one wrote- no I have both systems and compare sensors, and here Canon are falling behind in terms of DR at base iso,noise and visual banding due the read out stage with longer analog path ways to digitalization.
Simple facts
So if you now have Sony with 14 stops DR and 1dx with 12, go out and do a test shooting of the cameras, a street in where half are in deep shadows and the rest in sun shine and then look in the shadows and compare

if so inferior, why have Canon stuff at all? Simple facts seem to state it's a waste of money.

Why bother doing that when, given a choice, I wouldn't use the 1DX for this situation? Given no choice, I'd use the 1DX with AEB. No worries. Every camera has strengths and weaknesses. Get over it.

The Pop Photo magazine just announced the Sony A7R as their camera of the year. Praises aside, they also said this:
" While we’re nitpicking, we’ll point out that the 7R’s resolution comes at the expense of more noise at higher ISOs. Canon’s EOS 5D Mark III, our 2012 Camera of the Year and still the reigning low-light champ, is way ahead of the 7R in this regard, with acceptable noise through ISO 25,600; the 7R hits this boundary at ISO 1600. We wish the Alpha 7R had some way of triggering accessory flashes without using another flash as a master. (Hint to Sony: how about a trigger unit for the hot-shoe?) And a camera at this level should have a second card slot rather than a single SD."

My understanding from tests other people did that if you down sample the 7R's image to the same size as the 5D3, the noise is basically a wash at high ISO's.
If you want to print big, you will always be better off with more megapixels, and in a worst case scenario of extremely high ISO you will never be worse off than you would be if you had a lower megapixel sensor.
