Ok folks, when will the next 5D/1Dx come out? Maybe in 3 years, many more, are you all saying that the technology is that slow? the cameras that just got release are here to stay for a while.
imo sensor design is slowing down.
today they are doing finetuning.
microlenses, faster read speed all fine, but how much does quantum efficiency increase?
as r.n clark wrote not much
Complications regarding the perceived performance of pixels, pixel size and sensor size in digital cameras over the last decade (about 2000 to 2009) is a significant refinement in technology. While the quantum efficiency of sensors in digital cameras has not really changed much, other factors that have improved include: fill factor (the fraction of a pixel that is sensitive to light), higher transmission of the filters over the sensor, better micro lenses, lower read noise, and lower fixed pattern noise.
you can´t expect huge jumps in sensor design today... well you can but that would be unrealistic.
making the sensitiv area of the sensor bigger (backlight, exmor) was a nice step but we will hit a wall sooner or later.
