Sorry I'm nonplussed. 75mp? really? Well depth must be pitiful in a 35mm format.
But if it is a corker of a chip, there is not much Canon glass that would do the sensor justice (I have a suite of L-series lenses and only 3 impress me, the 200mmF2.0, 500mm F4.0 and a Sigma 8mm fisheye (yep I know....
)
Just my 2 cents worth....
