Finally something we can both agree on!

When printed at the same size (and why would we be comparing systems in any other matter), more pixels will yield more detail every time (all else equal).

Yeah a big ONLY if all else equal, that's the point.

Well, I mean, duh.  The point is, everything can be made equal except the lenses (although the lenses are often, if not usually, close enough).

But how to make everything else equals? Do you have to use a better technique such as tripod and the best lens on D800? Otherwise the difference is much smaller due to imperfect techniques and lens.

To achieve all else equal such as similar per-pixel level IQ...

And again, Peter, per-pixel IQ is meaningless.  It's the photo we're talking about here.  I mean, if we're not talking photos, then there's no point to this "conversation".

But that directly affects cropping capability and print quality. Don't they?

...you' need better technique on D800 such as the best lens (such as Sigma 35/1.4) on tripod, otherwise the advantage is disappearing quickly.

Yes -- the *advantage* will disappear quickly with poor technique (or narrow apertures where diffraction is dominant), but the *advantage* will always remain.

Becomes much smaller or even noticeable.But I am glad you finally agreed up the value of a good technique

See, DXOMark shows with a better lens such as 24-70L II 5D3 actually has better perceptual sharpness that roughly based on MTF 30 resolution in beating D800 with 24-70G, whoops, no mention if D800 not take on a sturdy tripod.

24-70L II on 5D3 vs 24-70G on D800

So DxOMark shows, with the particular lenses they tested, that the Canon lens is significantly better than the Nikon lens.

No, DXOMark tested entire system not lens.  Sensor or lens doesn't take photos alone but must work together.

Did you read Hans' post?


I did.  Like I said, the D800 will resolve a maximum of 28% more linear detail than the 5D3, all else equal.  If it has a better lens, then more.  If it has a lesser lens, then it can even resolve less.

28% only on paper but in reality as Hans and others experienced, the difference is very small.

However, this is neither here nor there.  If the 5D3 had the D800 sensor (and, by the way, the 5D3 with the D800 sensor in the 6D body is nearly my ideal camera) then the 5D3 would have produced better photos still.

In theory yes. In reality if you only print to 20x30" or view to 4000-pixel wide, then the difference is hardly noticeable. Personally I don't believe cropping but native length lens.

Whether or not the photos would have been "enough better" to be worth the operational downsides is another matter entirely.

Agreed. So as DPR review said, you do need to use the best technique such as the best lenses and on tripod to fully leverage D800 resolution in order to print in excellent quality to billboard size 40x60", LOL.
