Originally posted by MrPetkus This is generally true but, to a certain extent, it depends on technology and the sensors in question. Which company and how many resources are being put into what size sensor? The 16Mp Sony Exmor APS-C exceeds the DR of the 16Mp Canon APS-H and comes really close to matching ISO performance. In 2 years APS-C sensors may trump today's FF in every respect. Similarly, the 4/3 processors today are better than the APS-C of 3-4 years ago.
But assuming all sensor sizes were progressing at the same rate and by the same company, then sure, bigger will be better.
Bigger is definitely better, but unless we're a pro like some of the fellas here, do we really need the big sensors?
A digicam, like K-5, for instance, meets all my needs, lowlight, daylight, whatnot.
For video, I use dedicated camcorder, mirrorless & no problem with overheating.
The next cam better blow my socks off to warrant the $2500 price tag?
