M6 ii

[Kayaker72]

Very interesting .... I thought of crop factor mostly as changing the field of view and not in terms of resolution. In that regard the M6II image from 16 ft looks to have similar field of view as the 5DMKIV at 10 ft thus the 1.6 factor. It does, of course get more pixels on target from a greater distance too assuming the two sensors being compared have similar pixel density.

As odd as this sounds, my idea of APS-C has changed over time. Currently, I more think of it as the image that you would get by cropping out the center of a FF sensor. You could do this "in camera" by having a smaller sensor or do it in post-processing if you started with a FF image. But they would yield the exact same image. The resolution of that image is determined by the pixel density. I have always known all of this, but I think I appreciate it more.

So, I really do not think of my M6II as a 32.5MP sensor, which it is. But, especially when comparing it to FF, more often think of it as an 82.5 MP FF sensor that is physically cropped. The benefit of the physical crop being smaller files, less expensive sensor.

Edit---yep, good article by Ari. It is a bit odd that I've always known this, but I do think I am appreciating the simplicity more. Where it gets a bit complicated is considering things like bokeh. For example, if I take the same image of a bird with my M6II and 5DIV, resize the bird to be the same size in both images in post process (mechanically cropped vs post-processing cropped), each image would have the same bokeh.
