Ok this is just a rough test and to be truly accurate everything needs to be the same. Still the results almost speak for themselves. The Nikon blows the 5D2 out of the water for iso handling. We all know this but I didn’t think the gap was that great. Both images are cropped from hand held shots taken inside at night under dull mood lighting. If you were a wedding photographer and you only had the 5d2 you would be bawling at that moment. On the other hand if you were a D3s owner you would be banking the cheques. It is unbelievable.

Check how much sharper the Nikon lens is too. Ok my 16-35 has never been that good but the nikon 24-70, and the 70-200 that I have tried are just brilliant. I will have the 1D mark IV soon to try out, early reports from my brother who is using it in Sydney have been underwhelming. He thinks it doesn’t look as sharp as the 5d2 footage add to that the crop sensor and he isn’t loving it. Still time will tell when he gets home in a couple of days and puts it on the mac.

My feeling is Nikon has the edge on Canon at the moment. I think their lenses are better and if a D700x or s comes out with the iso performance of the D3s and the file size of the D3x I will be first in line to get one. Hell I still might just get the D3s and be done with it. I think the times they are a changing!
