Jeff Ashcroft reports that the 5D3, to his eyes is at least 2-2 1/2 stops iso improvement over the 5D2. My source that has had a 1Dx in his hands says the same thing but more like 3 stops improvement. The 1Dx is supposed to be better than the 5D3. If reports are true and the 1Dx exceeds a 5D3 by 1 stop,,,you have your answer.
6400 looks very clean and usable on these 5D3 files coming in. I will bet 8000 is going to be usable as well. If the 1dx is 1 stop improvement, and it very well could be more with the dedicated sensor, you have your 4 stops. When i shot a 25000 ISO JPEG file at wppi,,my jaw dropped when i brought the zoom all the way in. It was cleaner than a 40d file i have at 1600 iso. It looked like 1000-1200 iso. Its that clean.
There is not enough stuff out on the 5d3 to get an accurate figure about ISO and IQ. However, I believe every word jeff has said. Even though he is a canon spokes person, his reputation is very solid among photographers. You can bet your butt that the 1Dx will beat out a 5D3 in the iso department. If its a stop,,look out.
We shall see. Lots of reasons to wait for a purchase this year. 1Dx performance is the primary one. I cant wait until digital picture and DP review get the reviews out on these cameras.
One thing for sure--- 2012 and 2013 will be a very expensive years for a lot of people in our industry.
I'm not doing a thing until 1Dx reports are out and we can get the facts. I'm bet-in 12000 ISO is going to look like 3200-4000 on the 5D3,,maybe better based upon what i saw and heard at WPPi. I think its a game changer camera.
I suppose we'll see when these hit the streets and Adobe releases updates for the 1D X and 5D3. I'm not going to make a move until these occur. Unlike a lot of people here I don't shoot for hire or sell my photography, it's a business tool. I've had to take cuts on several contracts and have lost others.
Hopefully Adobe has the updates up for the 5D3 soon, no telling about the 1D X since we don't even have a firm price or delivery date.
