Originally posted by attack11 even if the iso performance is close to being as good, you won't get the ff goodness that the 5d delivers. every iso comparison i've seen online shows it's pretty useless at/above 3200. if that can be corrected with firmware updates, great. otherwise it's another k10d imo.
dont forget the 5D is 3 year old technology, the K20D is utalizing a newly developed chip.
are bigger pixels better than smaller pixels at capturing noise free light, in general, yes
but if someone goes out and develops a smaller pixel that can absorb light just as well, they just solved the problem didnt they?
you know regular CD roms? by your arguments Blue Ray disks are a pointless development.
