I want the sharpest images with the most detail possible.
- Resolution increases detail (to a limit)
- Noise decreases sharpness
Therefore, I have a dilemma. I am looking to purchase a new DSLR: either the Canon 5DS (R) or the 5D Mark IV.
The 5DS (R) has increased resolution (50MP), therefore increasing detail (to a limit). It does, however, have smaller pixels due to this increased resolution, meaning it has more noise in low light, thus decreasing sharpness.
The 5D Mark IV is the opposite. It performs better in low light, thus increasing sharpness, but it has fewer MP, meaning it shows less detail.
My question is this: If I want the sharpest picture with the most detail (e.g. close-ups of wildlife), which DSLR should I choose? I currently struggle with my photographs because my shots are always ruined by noise (currently using the Canon 700D), making them look unsharp. I understand both cameras will perform better than the 700D, but I want to know which would perform best, and what the differences would be.
Thanks for your help.
I use the Canon 100-400mm MkII, so lens quality is not an issue. I understand a balance is required between resolution and low light performance, but what I'm really hoping for is a specific answer. E.g. "For an ISO less than 6400, the 5DS R would be sharper, but at higher ISOs the image would be sharper with the 5D MKIII because of the reduced noise"
