Reopening  a can of worms, equivalence and now... bokeh full frame vs crop sensors

Uhmmm... 2 things:

 

1. He means blur, not bokeh. Bokeh is about the quality of the blur, not the amount.
   
2. Equivalence is about the amount of blur already. 56 x 1.5 = 84mm Same FOV. f1.2 x 1.5 = f1.8. So, same blur.
   

And yes, if you want the same exposure time, again the crop factor. APS-C ISO 400 -> FF 400 x 1.5 x 1.5 = ISO 900. Same exposure time.
