>>4373280>Wouldn't the fix to this just be opening the aperture up on FF to 1.4 or 1.8?Yeah. That's my point, a lot of the time you won't benefit from the shallower depth of field from full frame. You don't need to worry about getting an f/1.2 on a crop body in place of an f/1.4 on full frame, at least not for the depth of field. There are other reasons like making up for the ~1 stop advantage a full frame sensor would have in terms of stuff like noise and dynamic range, but with most portraits you're probably going to be able to shoot at or close to base ISO.
>You're getting less bokeh because you're having to stand further back for the same framingI don't know if I'd say less, just different. You'd be getting an enlarged background on the crop body the same as if you went from an 85mm to a 135mm on the full frame body. This is a bit of a shit example but it was quick and you can still get a rough idea of the difference, using a 50mm and going from ff on the left to aps-c mode on the right. The blurriness of the stuff in the background stays roughly the same, not a drastic difference you'd notice unless you were literally comparing side by side, but things are going to appear larger with a crop body.
