So, to not must have a crop as second body for better reach FF must currently have 46MP. They absolutely must fix this because I don't always want to carry a second body.
I'm new to digital photography so the following could be a stupid questions.
Are you talking about doing the crop in post to simulate the same effect of a crop sensor?
Also I read an interesting article the other day from a National Geographic photographer (http://photocinenews.com/2010/10/22/nat-geo-shooter-ben-horton-compares-canon-glass-to-zeiss-glass/
) saying that the 5d mark II sensor can capture more detail than the Canon L lens can give it, so would we really benefit from 46 MP with the current lenses?
Would Canon need to make new and more expensive lenses to take advantage of 46MP? I looked at the prices for some medium format camera lenses and they seem to be significantly more expensive
Since the only drawback of more pixels is file size and possibly frame rate, which both may be addressed in different ways, there is no reason to not fix this very severe problem.
Does ISO performance/sensitivity get sacrificed at the cost of higher pixel densities since the pixels are a lot smaller?
