lot of rubbish , there are a big difference between 14 stops of DR and no pattern noise and 11 with pattern noise, show me a cleaner camera from Canon  than d600, d800 at base iso and DR range and I pay you 100 dollars cash

100 dollars? Nah, I want 500.

I don't think you are a troll as many tend to believe. But I do sometimes feel that you are like a kid. You keep saying the same thing again and again, but never can come up with a good example where D800 or D600's shadow lifted areas are noise free and usable. You are not doing any justice to Nikon either. I have seen better examples.

BTW, I didn't say Canon cameras are cleaner than Nikon at base ISO. I don't think anybody ever did.

Keep up the crusade against all the noise. Never let people like me or others to distract you.

Here is a better example from D600. Exposed for the bright sun.

Shadow lifted, noise reduced

To be fair, one will have to admit that no Canon camera will come close. Image is noisy, but will be usable in a small size.

Sure we all know Nikon cameras win hands down in such scenarios that exposes on highlight then pull deep dark shadows many stops.  No dispute on that.  However such processed photo is better than no photo but still a crappy photo from perspective of IQ.  A better technique is available for this particular scene by using Singh-Ray Reverse GND filter that will dim sunlight on horizontal line but will still expose normally on the lower half part of the main subject, the boat in this scene.  You will have a much better photo by using the filter and shoot on a tripod.

Extreme shadow pulling doesn't replace better techniques but could rescue a photo otherwise will definitely throw out, just lesser of evil

OP's photos are underexposed.  I'd expose normally in that scene.  Sure the ceiling lights will be overblown (ceiling lights or "highlights" are not persevered well in such under-exposure photos anyway) but you will have much better IQ in church details.  OPer used much better Sigma 35/1.4 on D800 while Canon 35/1.4 on Canon so it's not very valid comparison.  He should either use Nikon 35/1.4 on D800 or also use Sigma 35/1.4 on Canon.I am not disputing Nikon has better DR or precisely extreme shadow pulling ability but just saying extreme shadow pulling is not a goo

.technique and will not result good IQ anyway.

It appears you've still not learned that it is not "shadow pulling.". And filters dont do a better job than having a higher DR.  you'll see...when Canon is able to deliver, you'll sing its praises.
