Paolo, thanks for posting these 5Ds shots. What's your personal opinion of the higher ISO shots?
I have the opportunity to step up to a 1DX used for about $600 above the 1D4. Do you think it makes sense of just hold off for a later 1DX Mark II opportunity?
I think the ISO holds up well considering it is 50MP.
But if you need more than ISO 6,400 then this may not be the body for you.
For my uses the 1DX is a step back because it has less pixels per millimeter than the 1D4.
If you are printing your images then this is the body to get.
I'd wait for the 1DX2 if you do not have a critical need
for a 1-Series body today but I expect pricing to exceed $6,800 when it gets shipped by 2016.
I expect the 1DX2 to be out by December or August 2016.
