No, it's definitively a subjective issue. If you go up and read your posts and Gordon's, you agree with one another on the objective fact that there is a measurable and demonstrable difference. Where Gordon differs from you is that under his shooting conditions (lighting, etc), workflow (Lightroom), processing, and output (eg print sizes), the difference is not a "quantum leap" as you put it. You can't measure and demonstrate a quantum leap.lol its not about agreeing to disagree or not. this is not a qualitative discussion. it is a quantitative concept not only noticeable anecdotally, but measurable and demonstrable.
