When pointed to the fact that the resolution figures of Canon’s “L” lenses are much higher than the EOS 5D Mark III’s 22MP sensor needs, the Canon executive said (machine translated):
I to higher pixel unnecessarily is the opposite, but there is also a feeling if there is a high-performance lens that matches the number of pixels (pixel pitch), and wanting to take a look at the descriptive power of its true. By ultra-wide-angle zoom image quality is good came out to the periphery, and we look forward to the advent of high-resolution model of the EOS.
Sounds like Canon is realising that customers want higher sensor resolutions on their professional bodies.[DC.Watch via CR]
