How much better is the 1D Mark IV than the 1D Mark III and 1D Mark II? 1 stop, 2 stop?
Though our experts like Roger and Co are yet to do their scientific tests (full well capacities and other such esoteric stuff), a few photographers have had a few thousand frames with it. So what is the verdict?
The Canon white paper says the Mark IV raw is 1 stop better than the Mark III and the Jpegs are 2 stop better than the Mark III. If the Mark IV can be one stop better, than the Mark III, then it would be fantastic. So how much better is it?
I haven't had mine long enough to give you "scientific" data but I can tell you this- my DMkIII is not going to be around long (and I'm one that almost never sells a camera). The DMkIV is what the DMkIII should have been.
I don't know about absolute stops difference. However, I find the MK4 to be super. I upgraded from a MK2 and find I am using higher ISOs and cropping more and still getting great images. ISO 800 is a no brainer and 1600 is still great. I have not yet used 3200. On the MK2 I had significant noise kick in at 800, contoled well with noise reduction. However ISO 1000 was a stretch on the MK2. So, I guess that's about 2 stops.;)
I'd like to just get my hands on a mk IV! I'm on a waiting list but as far as I can see none has been shipped in eastern Canada. I guess we are just small potatoes out here.
My experience is the same as Ed. To be honest those who thougt we would see noise control at the same quality as the D3 at very high ISOs were ignoring the physics.
I still need to do controlled testing and some flight but I am really happy with what I see.
