Oh, I get it. You were confused by the "equivalists" who claim things like bokeh is better on FF, DoF is more shallow on FF, etc. I think it is best to just ignore all that, as it is based on convoluted comparisons. Basically, they want you to take a photo with FF camera, then go out of your way to try to imitate that photo with a crop sensor camera, to get the exact same FoV, DoF, and bokeh. And since it is impossible to get the same focal length, FoV, DoF, and bokeh at the same time, they claim APSC failed - it has to sacrifice some of those elements, like DoF, to achieve a "similar" photo. But this is a skewed comparison. Using less or more of the sensor, using a bigger or smaller film, will not change the rendering of the image. It will only change how much of the image area is recorded. Trying to then imitate a theoretical DoF and maintain a FoV, upsampling the photo and so on will always skew the results in favour of the "native" format
FF does not give better bokeh or shallower DoF. It just gives a bigger frame. If you try to force a camera with a smaller frame to get the same FoV and DoF (at the same time), you will have a hard time, and possibly get sub-par results. But nobody actually takes photos in that manner, first looking at DoF and bokeh magnification. Theory and practice.
