while the raw dynamic range similar to 5D mark III

估计就是那个sensor的延展。。。

以为是大招，结果是一坨大牙膏
t's convenient to think of the new 50MP as essentially an upscaled version
of the 20MP sensor inside the EOS 7D Mark II - minus the 7D II's Dual-pixel
AF. The pixel pitch of 4.14 microns is certainly very similar across both
sensors. Accordingly, Canon tells us that at a pixel level, noise levels
should be very similar to the EOS 7D Mark II and slightly better than what
we'd expect from a 5D Mark II (note: not a 5D Mark III). Oddly though,
maximum ISO sensitivity is capped at ISO 6400, which extends only up to 12,
800. Even more oddly, a Canon representative openly described this
limitation as ‘arbitrary'. This is strange because the EOS 7D Mark II (
remember the pixel pitch of its sensor is almost the same) can confidently
shoot at ISO sensitivity settings up to 51,200.
As far as dynamic range is concerned, we're told that the new 5DS and 5DS R
should give the same performance as the current EOS 5D Mark III. If true,
this means that the new cameras won't be able to offer the same industry-
leading dynamic range of Sony's current APS-C and full-frame sensors, but at
least it isn't a step backwards. And hey - 50MP!
