Thanks, I see what you're saying, but while the subject may appear "in focus" the "look" of the image will be different. Of course, this can be more desirable depending on what you are going for.Love the comparisons you're generating. Take this comment with a big grain of salt, but one other thing to consider is that if this is intended for social media, you don't need f/4 on the FF because at such small viewing sizes, you can't judge sharpness or what's in focus very accurately. IMO, "apparent" dof is significantly increased at small viewing sizes. This gives some advantage back to the larger sensor because it has more fudge room.
