Originally posted by beholder3 EVF images are never "downsampled", just as this would require both full readout plus downsampling on the fly. Just the same as video. The EVF is just a secondary display, no different to the main display on CMOS cameras.
The K3 I sensor doesnt provide 30 FPS full 24 Mpx sensor readout plus downsampling only because you can take and view on the display 30 FPS uncropped video.
Both low res displays on a mirrorless camera only show selective pixel readout.
Not. Any other parameter you might want to introduce is useless.
MPx/sec is the key compound measure for a cameras ability to capture image data and move it through whatever pipeline and processing into internal buffer before writing it to memory card. Nobody cares what happens in partial steps in between.
A sports shooter doesnt want 60 FPS 1.2 MPx images. They want the full data saved.
It is not a full readout for the evf, but it is also not just the amount of pixxels shown, especially for the high resolution cameras with evf. I cannot find specific data for the z7 right now, but it is a down sample, quite similar to the milcs that downsample 5k readouts for 4k video.
MPx/sec is very unefficient. The only thing that matters are fps, buffer size and time to clear the buffer. The nx1 can buffer pictures of less than 2 seconds in burst mode and takes a very long time to put them to sd card. How can this be a valid criteria for sports shooting or determining the compute power of the camera? The Canon 1DxM3 puts out roughly 400 MPx/s and is a totally different beast in any usecase. It computes everything faster and shoots faster by any means, there is nothing the NX1 can do faster, simply nothing.
With your parameter, the NX1 beats the Canon 1DxM3 in terms of speed and compute power and this is redicoules.
edit: Sony claims that even the A7 III supersamples 24MPx to 4k for video
