I have the 5D. Was not going to upgrade, but I am thinking of buying a wide format printer and was thinking images from a 22mil pixel camera might look much better than one from a 12 mil camera.
Am I right -- if printing very large?
I could upres in Photoshop, but what do others think? thanks.
Sorry, you've probably made your camera choice months ago, but here's some experimental evidence:
Recently took 5D and 5DII into my studio with a still life setup. Switched bodies on tripod using same lens (24-70L), same focus, same settings, same lights, same everything.
Took images into Lightroom and corrected slightly (slightly different contrast due to different processor---very minimal). Images then looked the same (except noted after the fact that an ant had crawled on a leaf of one )
the images at different sizes and put them side by side. This is more important than pixel peeping.
At 11 x 16.5, no difference at all---needed to find the ant to tell them apart
16 x 24, barely
visible difference with overlapped images to compare one spot and peering at closer than arms' length
20 x 30, can see a slight difference in certain areas of the image. didn't need to look for the ant
So up to 16 x 24 the 5DII doesn't make a significant difference. Larger than that, you can start to see a difference. BUT, now factor in how far people are going to be from large prints. Your clients and friends are rarely going to put their nose up to a 24 x 36 print---they'll be 2 or 3 feet away. When I stood back that far from my test prints the 20 x 30 were indistinguishable.
As others have mentioned, keep your technique pristine and for most purposes the 5D will be fine. Super-sized prints for galleries need more.
